(0 - 25 m tow) than nets fished in deeper, less productive waters
(0 - 100 m). In any case, without such a device, it obviously is
impossible to predict the efficiency of a net at the moment it
encounters a layer of plankton.
Recommendations
Devices are currently available, such as high-frequency sonar,
which graphically delimit layers of zooplankton (see Part VI).
Combined with such graphic devices, a net equipped with the device
described herein is a logical companion, permitting precise estimates
of net efficiency at any level during a vertical tow.

SECTION IV
ANALYSIS OF ZOOPLANKTON POPULATIONS
Both seasonal patterns in species abundance and estimates of
secondary productivity are important in understanding the dynamics of
competing species, let alone relating their dynamics to that of the
primary producers. We have produced detailed information on the
abundance of all species of Cladocera and Copepoda (Crustacea) at the
60 stations of the IFYGL Lake Ontario grid. Estimates of standing
crop are vital in estimating zooplankton grazing. Horizontal
distribution is important to understanding the development of
populations, with regard to the non-homogeneous or clumped distribution
of their food resources.
SEASONAL DISTRIBUTION OF THE CRUSTACEA
Bosmina longirostris, the most abundant cladoceran of Lake Ontario,
began to increase in abundance in April and May in inshore waters,
although rapid population growth does not result in large standing
crops until June (Table 1). Maximum densities were reached in
August inshore. In deeper, offshore waters, the initial standing
crops were lower in May and June, but July and August densities were
as high as 63,691/m3 (Table 2). Following a population crash in
November, Bosmina over-wintered as parthenogenetic females, at densities
of only 0.3-10.2/m3.
Bosmina coregoni, a larger Bosminid considered characteristic of
oligotrophic waters (see Section VIII), is also found in Lake Ontario.
It likewise overwinters at densities of k - 65/m3, but is currently
much less successful in Lake Ontario, reaching a maximum density of
2,050/m3 offshore in October (Table 2).
Among the daphnids, Daphnia retrocurva is currently most successful in
epilimnetic waters, again with an August maximum (11,965/m^) offshore
(Table 2). The smaller Ceriodaphnia lacustris is chiefly a summer
form, as is Holopedium gibber urn. Diaphanoscma sp. is a winter form,
in relatively low numbers (4 - 9/mJ) from November through March
(Table 2).
Polyphemus pediculus, a non-bivalve cladoceran often considered
predatory, is found only during August in offshore waters (Table 2).
Cyclops bicuspidatus was the most common cyclopoid of the offshore
waters, whereas Tropocyclops prasinus was more common inshore (Table 2).
Cf bicuspidatus was most abundant during July and August (l2,V78/m3),
and overwintered at high densities (121-^52/m3) in offshore waters
(Table 2). C. vernalis likewise reached its maximum abundance in
10
-------
August, but never exceeded densities of 650/nr. Tropocyclops is an
autumnal species, which reached densities of 1^,Ib5/m^ offshore at the
same time. Thus not only do C. bicuspidatus and T. pr a sinus show
different seasonal patterns, tiut their gross horizontal distribution,
to be examined further, is complimentary.
The calanoid copepods, often abundant in oligotrophic waters, are a
diverse assemblage in Lake Ontario, but are never especially abundant.
Unidentified copepodites were most alondant inshore during October-
November. The classical oligotrophic indicator, Diaptomus sicilis,
was most abundant offshore in June (lo^/m^) and July (119/m3"J^
Burytemora affinis, the recent invader from the sea, never exceeded
2350/mJ (August) in inshore waters (Table 1).
These data on relative density clearly indicate that Lake Ontario is
characterized by a single seasonal peak in zooplankton production
which occurs during August. Most species overwinter in the lake as
adults, the exceptions being the rare cladocerans, Holopedium,
Polyphemus and Diaphanosoma.

HORIZONTAL DISTRIBUTION OF CRUSTACEAN ZOOPLANKEOH
AT SPECIES POPULATION MAXIM
Water Duality is reflected in the horizontal distribution of the
crustacean zooplankton of Lake Ontario. From our sampling during the
1972-73 IFYGL survey, the distributions of each species are available
from a variety of water strata. In this section we will discuss the
horizontal surface (0 - 5 m) distribution of dominant forms at the
time of their seasonal population maxima.
Biologically it is important to interpret horizontal distributions.
Inputs of plant nutrients from rivers tributary to Lake Ontario likely
influence secondary production. Thus areas of unusually high standing
crops of zooplankton are likely indicators of stimulation by pollutants
of the nutrient-poor Ontario ecosystem. Likewise, physical factors
like upwelling, with associated increases in available plant nutrients,
may influence observed horizontal distributions of zooplankton. In
the final interpretation of Lake Ontario results, such information
must be considered.
Lastly, the Ontario ecosystem is extremely dynamic. Large populations
of warm-water cladocerans, initially developing inshore, may be
carried offshore, with little final correspondence between the location
of a clump in time and the environmental factors which led to its
development.
The Cladocera
The horizontal distributions of the cladoceran and copepod crustaceans
will be discussed as a sequence of possible eutrophic indicators from
Bosmina longirostris, the most useful key to extreme eutrophy, to
Diaptomus sicilis, the most primitive oligotrophic form,
The smallest major cLadoceran, Bosmina longirostris» is likely a
eutrophic indicator because of its diet, which permits grazing on
large forms of aLgae. It is predominantly an inshore form (Section V),
presently close to urban centers. Bosmina longirostris was found in
Ontario over 12 months, but reached maximum density during August 1972,
Clearly the horizontal distribution of B. longirostris is (a) character-
ized by greater densities inshore, and fb) associated with urban
shoreline development and river inflow. At maximum development from
21 - 25 August 1972, it reached densities of greater than 200,000/m3
off Toronto, Ontario, and 300,000 off Oswego, New York (Figure 3).
Likely the Oswego case was influenced as much by the agricultural
nutrient load of the Oswego River as by the city itself, whereas the
effect from Toronto is likely more directly associated with nutrients
originating from the city. In both cases, of course, such nutrient
stimulation is thought to have its primary impact upon the phytoplankton,
with the response which we have observed so clearly in the zooplankton
-------
Figure 3. Density (no./nr) of eutrophic Cladoceran Bosmina longirostris

Ontario at 60 stations of IFYGL Biology Program
-------
a secondary one. But the usefulness of Bosmina longirostris as an
indicator of stress is obvious.
Bosmina coregoni, almost twice as large as B. longirostris at maturity,
has been considered an oligotrophic form. In contrast to the inshore
preferences of B.-longirostris, B. coregoni exhibited offshore blooms
of up to 30,0007m3, also during 5l ~^~^5 August 1972. These intense
concentrations were largely confined to the eastern end of Lake Ontario
(Figure k), with large aggregations of 20,000/m3 and I,500/m3 offshore
of Rochester, New York, and a cell of lesser density at the outflow of
the lake.
The third common cladoceran, Daphnia retrocurva, while not classically
used as an indicator of eutrophication, is a small species which
withstands fish predation well, and thus is very successful. Large
inshore concentrations were found again at Oswego (35»000/m^) and just
eastward from Oswego at Nine Mile Point (10,000/m3), the site of a
nuclear power plant complex from 21 - 25 August 1972. A third cell
of maximum densities of 20,000/m3 was located west of Rochester
(Figure 5).
The Copepods
Diaptomus sicjlis, in sharp contrast to the cladoceran Bosmina longiro-
stris, is the most oligotrophic form in the Great Lakes, and remains
the dominant species in oligotrophic Lake Superior. As expected of an
oligotrophic indicator, it develops its maximum population earlier (July)
than Bosmina longirostris (August), and this development occurs in
deeper, cooler midlake water-masses. Currently not nearly as abundant as
Bosmina, D. sicilis densities during 1972 did not exceed 375/m3. Two
large cells were found in eastern Lake Ontario (Figure 6), one occupying
most of the deepwater basin north of Rochester and Oswego, and the other
between this larger cell and the outlet during the period 10 - 1^ July
1972. Less intense inshore development was observed in shallow Mexico
Bay in the extreme southeast corner of the lake and in the western
portion just east of the Niagara River inflow.
Diaptomus minutus, a more mesotrophic species with the predatory
avoidance characteristics associated with small size at maturity, also
exhibited an offshore distribution at maximum development. Large
clumps with relatively low densities of 300 - 1000/m3 were found in both
the western and eastern parts of Lake Ontario frcm 12-16 June 1973»
In contrast to the cladocerans, these cells were always centered well
offshore (Figure 7).
The cyclopoid copepods have not been used as indicators of pollution
in the traditional sense. They are likely predators which obtain a
living by piercing and sucking body fluids from rotifers and small
crustaceans. Three species are dominant in Lake Ontario. In order
of abundance, these are Cyclops bicuspidatus, C. vernalis and
Tropocyclops prasinus. Cyclops bicuspidatus reached its population
maximum in July, C. vernalis in August, and Tropocyclops in October 1972.

Cyclopoid copepodites, or immatures of the above three species, were
abundant from 21 - 25 August 1972, both inshore and offshore (Figure 8).
A large cell with maximum densities of 50,000/m3 was present in shallow
eutrophic Mexico Bay in southeast Lake Ontario, but the greatest
concentrations were in the central basin of the lake (100,000/m3) and
inshore just southwest of Toronto (90,000/m3). Cyclopoids develop
rather slowly, and it is likely that large aggregations may drift
about the lake for long periods of time with little relationship to
the origin of the underlying environmental factors responsible for
their initial population explosion.
Cyclops bicuspidatus, the most, abundant of the cyclopoid copepods, is
a spring species reaching a maximum abundance by early (10 - lU) July.
In eastern Lake Ontario it was most abundant over deepwater at Station 75
(20,000/mJ). In the western waters a large cell was located in midlake
(70,000/nr3) and another inshore at Toronto (50,000/m3). The density
of Cyclops in the inflowing waters from Lake Erie was apparently rather
low (10,000/m3), as illustrated in Figure 9. Since Cyclops is a seizer
and serum sucker probably feeding upon rotifers and small crustaceans,
its distribution may reflect the abundance of such foods, but is
likely less closely tied to algal and nutrient distributions and thus
is not useful as an indicator of environmental stress.
Cyclops vernalis was much less abundant than C. bicuspidatus. Two
small concentrations were observed in western~~Lake Ontario during
August (Figure 10), one off of Toronto (1500/m3), from 21 - 25 August
1972. Elsewhere densities ranged between 250 and 1500/ra3. Together
with the data on C_. bicuspidatus, these densities of C. vernalis may
enable modellers to estimate the incidence of zooplankton (non-fish)
predators.
Tropocyclops prasinus is an autumnal form which reached densities of
335,000/m3 during October 1972 (Figure 11). it was found in a very
large inshore bloom (200,000/m3) west of the Murray Canal, which
connects the Bay of Quinte to Lake Ontario, from 30 October through
3 November 1972. The relationship of such blocms in Popham's Bay to
nutrient inputs from the Bay of Quinte should be answered.
Generalities Regarding the Horizontal Distribution of the
Crustacean Zooplankton
Certainly the cladocerans are most abundant close to shore, while the
copepods prefer deeper waters. These data illustrate differences
within these two orders, indicating clearly that some cladocerans
prefer more eutrophic conditions than others, while seme copepods are
more oligotrophic than others. Bosmina longirostris, clearly the most
eutrophic form, exhibits a tendency to explode in areas of known
perturbation, especially off the Oswego River and the City of Toronto.
Bosmina coregoni, a more oligotrophic indicator on a relative scale,
is found in large offshore clumps, well away from major sources of
inorganic and organic plant nutrients. Daphnia retrocurva is

intermediate between the Bosminas in its response, probably closer
to B. longirostris.
Clearly Diaptomus sicilis. often called the most oligotrophic crustacean,
exhibits an offshore distribution, as does Diaptomus minutus. From
our observation, strongly influenced by information in the literature,
we have erected a continuum of species, indicative of early oligotrophy
to eutrophy. For these found in Lake Ontario, the extremes might include:
Early oligotrophy: Diaptomus sicilis
Oligotrophy: Bosmina coregoni
Mesotrophy: Diaptomus minutus
Eutrophy: Daphnia retrocurva
Late Eutrophy: Bosmina longirostris
Communities of Lake Ontario Under Stress
Four restricted areas of this tremendously large system are currently
under stress, as indicated by their zooplankton communities. These
include the waters adjacent to Metropolitan Toronto, those off the
Oswego River, and three shallow and productive Bays, Mexico Bay in
southeast Lake Ontario and Popham's and Weller's Bays adjacent to the
Murray Canal which connects Lake Ontario to the Bay of Quinte on the
northeastern Canadian shore.
We have concluded that these areas are under stress, based on a
consideration of the relative numbers of cladocerans and calanoid
copepods found at maximum density, usually during July and August,
In the four areas under stress, the mean density of Bosmina longirostris
at population maximum was 150,000/nP, while that for Diaptomus sicilis
and minutus was 312/m > for a Bosmina;Diaptomus ratio of ^80:1 (Table 3).
In more oligotrophic waters at stations 17 » 77 and 83, the mean density
of Bosmina was 1000/m3 and that of Diaptomus was 255/m^, for a
Bosmina;Diaptcmus ratio of 3-9:l- Thus Diaptomus, the oligotrophic
form, is relatively more abundant in oligotrophic waters as indicated.
Bosmina, on the other hand, was 150 times more abundant in eutrophic
than oligotrophic waters in this example.
Clearly, the Environmental Protection Agency should consider solutions
to problems of accelerated eutrophication in U.S. territorial waters
near Oswego and especially in Mexico Bay, and the Canadian government
should be concerned with the same problem in the area of Toronto and
in shallow Popham's and Weller's Bays on the northern coast of Lake
Ontario. It may be possible to separate cultural causes from simple
morphometric (depth) relationships in these cases. That is, the
problems associated with the input of nutrients from the Oswego River
and Toronto may have engineering or other technical solutions. The
problems of high productivity in the shallow bays may be primarily-
associated with their morphometry. These bays may be important feeding
grounds for young fishes and a slowing of their eutrophication may
be neither feasible nor desirable.

SECTION V
EFFECTS OF URBAN CENTERS OS ZOOPLAMKTON POPULATIONS
INTRODUCTION
The zooplankton faunas of the Leurentian Great Lakes reflect water
quality, with seasonal population equilibria apparently achieved in
a short time between the quantity and quality of algal foods and the
density of grazers. Thus, to some degree, the variety and abundance
of the zooplankton is a reflection of the secondary influences of
nutrient loading. In a similar fashion the population size structure,
and ultimately the species composition of the zooplankton, is influenced
by their fish predators (Wells, 1970).
As a working hypothesis, we suggest that urban development along the
shores of Lake Ontario influences the community structure of inshore
zooplankton populations during a growing season. A proposed mechanism
might involve the input of nutrients, in turn stimulating the production
of bluegreen algae, or the discharge of substances inhibitory or lethal
to zooplankton growth. However, we will not attempt to further define
this mechanism now. The purpose of this particular analysis of data
was to test this hypothesis. Basically three questions are important.
First, do differences in community structure occur lakewide on a
defined horizontal scale within a growing season? If so, are such
differences in community structure related to long-term changes
demonstrated for Lake Ontario? And most importantly, what do such
differences infer regarding the eutrophication of Lake Ontario's
ecosystem?
Definition of the time-scale of changes during community succession is
important to understanding eutrophication. This succession has been
partially answered. Over time, the zooplankton of the Great Lakes
probably have adapted to both changing foods and predators. During a
recent period of accelerated cultural eutrophication commencing about
1900 (Beeton, 19^9)» major changes in zooplankton community structure
probably were initiated. Diaptomus sicilis, the dominant form in
Lake Superior, seems the most oligotrophic form in the Great Lakes
(Patalas, 1972). Toward the eutrophic end of the spectrum, the summer
zooplankton community of Lake Ontario has shifted since 1939 from
dominance by Diaptomus to an abundance of Bosmina longirostris (McNaught
and Buzzard, 1973)•Thus long-term shifts have been documented for
Lake Ontario and probably have occurred in all of the lower Great Lakes.
Lake Ontario is the seventeenth largest body of freshwater in the world
(Hutchinson, 1957), an international resource of tremendous value to
both the united States and Canada. Lake Erie, upstream to Lake Ontario,
is certainly responsible for important organic and inorganic inputs.
Thus it is also the purpose of this analysis of the Ontario ecosystem
30
-------
to detect the ecological impact of in basin inputs of nutrients and
other substances. This will be attempted by dividing Lake Ontario
into three segments, with special attention given to proximity to
human influence. These designated areas thus include (l) inshore
waters adjacent to urban centers and less than 30 m in depth, (2) inshore
waters not offshore frcm but adjacent to rural areas, and (3) offshore
waters greater than 30 m in depth.
Vertical plankton hauls were taken from the NOM R/V Researcher at the
60 IFYGL sampling stations (Figure 12) on the cruises of 12 - 16 June,
10 - Ik July and 21 - 25 August 1972. Fortunately these 60 stations
selected by the IFYGL management were comparable within the framework
of our lakewide division. The urban inshore stations had a mean depth
of lU.O m, whereas those stations designated rural inshore had a mean
depth of 18.5 m.
COMPARISON OF ZOOPLANKTON COMMUNITIES
Basically three types of comparisons will be made between populations
inhabiting urban inshore, rural inshore, and offshore waters. First
the relative densities of each species will be contrasted. Secondly,
traditional measures of Shannon-Weaver diversity, richness and evenness
will be utilized. Lastly, community indices, including the theoretical
community competition coefficient (ji.) and community carrying-capacity
(K) (Levins, 1968) will be used. Discussion and application to Great
Lakes problems of these indices by Vandermeer (1972), Lane and
McWaught (1970), and McNaught and Buzzard (1973) may be consulted for
information on formulations and application.
Density Differences
In comparing densities (Table k)} relatively higher numbers, but fewer
species of many cladocerans were found in urban inshore waters.
Daphnia longiremis was limited to offshore waters, while Bosmine
longirostris, Ceriodaphnia, Chydorus, Polyphemus and Diaphanosoma were
usually more abundant offshore. However, on a unit volume basis (no./m3)
the cladocerans, usually considered warm water organisms, were more
abundant inshore than offshore during June-August (mean of 6i4-,325/m3
versus 33,737/m3). Roth and Stewart (1973) found a similar situation
in Lake Michigan. In contrast to the cladocerans, the cyclopoid
copepods did not exhibit such an obvious trend. Among the calanoid
copepods, both Diaptomus minutus and D. oregonensis were more abundant
offshore, as was Limnocalanus, a cold water form. A two-way analysis
of variance demonstrated that zooplankton densities varied significantly
(p < .01) with time (Table 7), but not with location. Clearly there
are seasonal pulses in zooplankton densities, as we have long realized,
but the differences between urban inshore, rural inshore and offshore
waters are not effectively described in terms of total crustacean
zooplankton densities.

Diversity Differences
Comparison of the three lake regions, losing Shannon-Weaver diversity,
as well as the richness and evenness components, illustrated some
significant differences between watermasses (Tables § - 6). In all
three summer months, the' urban inshore areas exhibited the lowest
diversity (1.13 - 1.66 bits), with rural inshore areas intermediate
(2.1*3 - 2.93) and offshore waters most diverse (2.9^ - 3-31). Note
that these ranges in diversity do not overlap. During the months
June and July fewer species (12 - lU) were found in urban inshore areas,
and the richness component was lower (2.1*9 - 3-85) than in offshore
waters (3.76 - ^.32). In August the evenness component accounted for
reduced diversity in urban inshore waters. The location and time
effects on diversity were both highly significant (p < .01), as shown
in Table 7.
Differences in Community Indices
Biotic communities should evolve toward a moderately low level of
interspecific competition, otherwise species extinction will force
such evolution. In apparently stable planktonic communities, as in
oligotrophic lakes, the mean community competition coefficient might
be on the order of 0.3. For a larger number of samples collected from
Lake Michigan the mean community alpha was 0.31 (Lane and McNaught,
1970). Thus a third comparison, between location and alpha, was
attempted (Table 7). During the months of June, July and August, 1972,
the mean community alpha was highest for the communities of urban
inshore waters. In two of three cases, alpha was lowest for communities
of. offshore waters. These indices suggest that offshore communities,
with reduced levels of potential interspecific competition, are the
most stable ecologically. In contrast, the urban inshore communities
were again judged least stable, and by using an index independent of
the previous Shannon-Weaver diversity computation. The effect of
location upon alpha was highly significant (p < .01), while there was
also a significant effect (p < .05) of time of year (Table 7). Thus
two ecological indices have suggested greater instability in urban
inshore regions.
Similarly, a second community index, carrying capacity (K), was higher
for urban inshore waters, as compared to rural inshore areas (Tables 5 -
6). Since this theoretical estimate of carrying capacity is calculated
using alpha (Levins, 1968), this conclusion is not unexpected. However,
the ratio (U/K) of observed density (u) to theoretical carrying capacity
(K) is probably a better index of eutrophication. During these same
three months the N/K ratio suggested that urban are-s were closer to
carrying capacity than rural inshore waters. Moreover, since we are
dealing with r-selection organisms, which fill only a small fraction
of their carrying capacity, it was logical that these ratios would
remain below 15$. It should also be noted that the offshore communities
of zooplankton are closest to theoretical capacity (11 - 12$). A
two-way AHOVA suggested that the effect of location on the ratio of NK

was not significant (p > .05) (Table 7). Thus the ratio of observed
to theoretical carrying capacity (N/K) does not confirm the other
evidence suggesting that dramatic changes are occurring within water-
masses off larger cities along Lake Ontario's shores.
SIGNIFICANCE
Fewer species of crustacean zooplankters were found in urban inshore
areas of Lake Ontario than in adjacent inshore or offshore regions.
While the cladocerans Daphnia, Ceriodaphnia and Chydorus are important
in rural inshore areas, they have given way to Bosmina longirostris
and Cyclops in urban inshore waters.
Ecologically it was significant that seasonal and geographical
differences in zooplankton distribution wherein the urban inshore
waters were presumed more eutrophic than offshore waters, paralleled
changes that have occurred in the zooplankton communities of the
Great Lakes over much longer periods of time. These findings thus
suggest that in waters offshore of urban centers we find drifting,
planktonic communities which are highly modified, even though drifting
along shore rapidly at velocities of 10 km/day (Scott, 1973). The
causal effects of changes in zooplankton community composition off
large cities quite plausibly are included in the concepts of algal
resource availability, zooplankton selective feeding, and zooplankton
predator abundance. These mechanisms are currently being investigated
in our laboratory.
From a management viewpoint, the indices of diversity and theoretical
community competition may be used to identify similar urban-influenced
watermasses. More importantly, such indices should be useful in the
conduct of surveys, especially as nutrient inputs to the Great Lakes
are reduced.

SECTION VI
ACOUSTICAL ESTIMATES OF ZOOPLAHKTON BIOMASS
THE ACOUSTICAL METHOD FOR DETERMINATION
OF ZOOPLANKTOH BIOMASS
The echo-Integrating sonar, especially designed to be sensitive to
particles of the size and density of zooplankton, has been described
previously (McNaught, 1973). The approach was to transmit an exact
waveshape (sound-wave) and detect the return, using a 100 channel
signal averager. Each channel thus corresponded to 1% of depth (or
time). The returning signal was simultaneously fed into an synchronous
demodulator, then to a storage oscilloscope, providing a picture of
zooplarikton abundance with depth over time. The data from the signal
averages, the heart of the system, were also displayed on an X-Y
plotter, and later processed from paper tape using a program described
below.
The 5-frequency sonar (53 or 80 kHz, 120, 200 and 500 kHz) operates
on the principal that the maximum reflectivity from small targets
(zooplankton) nearly the same density as water itself is obtained
when the wavelength of sound is equivalent to the diameter of the
(sphaerical) target (McNaught, 1968, 1969). Thus, as successively
higher frequencies are employed, smaller and smaller organisms can
be detected. For example, sound at a frequency of 200 IsHz is maximally
reflected by particles 2 mm in diameter, with reasonable sensitivity to
particles down to 1 mm in diameter. Sound at a frequency of 500 kHz
is maximally reflected by particles 0.8 mm in diameter, and to some
extent by particles as small as O.ij- mm (Figure 13). Thus these two
frequencies combined can be employed to give an estimate of the biomass
of zooplankton between 0.8 and 2 mm in diameter. In the same way,
signals from the 200 kHz and 120 kHz projectors provide an estimate of
the biomass of zooplankton between 2 mm and 3 mm in diameter, and the
120 kHz and 80 kHz projectors provide an estimate of the biomass
between 3 mm and 5 mm, which is chiefly fish larvae and fishes. These
low-frequency projectors are thus used to eliminate echoes from fishes
from the zooplankton biomass estimate (or alternatively, to estimate
the biomass of fishes in Lake Ontario),
Corrections for properties of Sound and Transducers
In determining the zooplankton biomass with depth using acoustical
techniques, only physical correction factors have been employed. The
necessary factors are (a) the relative strength of the acoustical
output (frequency normalization) for each frequency transducer? (b) the
relative attenuation of sound at 80, 120, 200 and 500 kHz, and (c) the
beam angle of the transducer (Table 8). These correction factors have
been employed in writing a program to correct raw field data.

Data Correction
In Table 9a we see an example of raw field data (first four sets at
80, 120, 200 and 500 KHz). These acoustical reflectivities have been
multiplied by the suggested correction factors (Table 8) to yield
four sets of "corrected profiles" (Table 9b). Then these corrected
profiles are subtracted (120 - 80 kHz, 200 - 120 kHz and 500 - 200 kHz)
to yield biomass estimates for particles of the three size ranges
previously indicated (Table 9c). Since the data are not useful in 1%
increments of the gated interval or scan depth, they are then converted
to acoustical reflectivity per 5 m interval, again for three size
ranges (last block) (Table 9d).
Calibration of Acoustical Technique
An empirically based calibration was made by comparing the sum of
differences in acoustical reflectivity, specifically between the
200 kHz and 120 kHz channels and the 500 kHz and 200 kHz channels,
with the product of numerical density of zooplankton and their mean
weight. This calibration utilized the data of the cruises of 21 - 25
August 1972 when animals were abundant and 30 October - 3 November
1972 when animals were relatively scarce. Because the 6kv aperture
net used to collect animals was most efficient over a 5 m tow, and
because the sonar likewise was most sensitive frcm 0 - 5 m, all
calibration points were based upon 0 - 5 m data. A linear regression
was obtained for the relationship between acoustical reflectivity
(D.C. volts) and zooplankton biamass (g/m3 dry-wt), such that biomass
(g/m3) is related to corrected acoustical reflectivity (D.C. volts)
as follows:
(Corrected )
Biomass (g/m3) = 0.681 + 13-53 (Aeoust. Ref)
Thus we observe (Figure Ik) that the acoustical technique is insensitive
to biomass levels of less than 0.68 g dry-wt/m^. At very low acoustical
reflectivity, it appears that biomass is overestimated.

VERTICAL PROFILES OF RELATIVE ZOOPIANKTOH BIOMSS
Since the trophogenic zone, or the waters where phytoplankton photo-
synthesis exceeds respiration, is confined to the upper 30 m in Lake
Ontario, previous studies of zooplankton abundance have centered upon
the upper 50 m of water (Patalas, 1969* Watson, 197*0« A major
contribution of the zooplankton acoustical samples is an indication of
abundant, zooplankton size particles at greater depths than 50 m.
Once acoustical data have been placed in 5 m depth intervals for each
station (Table 9)» it is relatively simple to produce a lakewide
estimate (Table 10) for each cruise. On 30 October - 3 November 1972,
2 - 3 ram particles (200 - 120 kHz) and 0.8 - 2 mm particles (500 - 200
kHz) were both most abundant in the deepest waters at 230 m depth
(Table 10). Summaries for the distribution of 0,8 - 3.0 mm particles,
the size-range for most crustacean zooplankton, are presented in Table 1]
and Figure 15. During 21 - 25 August 1972 particles were relatively
most abundant between 100 and 200 m depth, from 30 October - 3 November
1972 zooplankton sized particles were most common in the deepest waters.
Over the period 12 - l6 June 1973» these same particles were most
abundant between 60 and 130 m depth. These average estimates of biomass,
made using acoustical techniques, are for all 60 stations of the IFYGL
grid and usually represent a mean derived from 5 days of measurements
made both day and night.

HORIZONTAL DISTRIBUTIONS OF ZOOPLANKTON BIOMASS
(ACOUSTICAL EST.)
Detailed analysis of horizontal distribution of column
bioaass (zooplankton g dry-vt7m^7 ~~~
21-25 August 1972 ---
The lakewide distribution of zooplankton biomass reached a maximum
during late summer 1972 (August). As expected the largest bicmass per
surface area was in deepwater. During 21-25 August 1972, notable
concentrations of biomass were observed at stations 85 and 89 in
eastern Lake Ontario and stations 32, Uk and ^5 in western Lake Ontario
(Figure 16). The mean biomass per unit volume of lake-water, considering
all stations at all depths, was estimated to be 11.8k g dry wt/m3. This
very high value resulted, as indicated in the previous section, as a
result of a large acoustical reflectivity from targets located at
100 - 200 m depth,(Table 12).
5-9 February.1973 ---
The lakewide distribution of zooplankton bicmass in February 1973 was,
as expected, lower than in August 1972, but again greatest in deepwater.
Three large cells are noted (Figure 17), one in the mid-western section
of the lake with a large area greater than 500 g/m , one in rnidlake
off Rochester, with 300 g/m , and one in eastern midlake with a biomass
of 150 g/m2. A single large inshore area of high zooplankton bicmass
was observed off the Oswego River, with a small area greater than
150 g/m, rather high for shallow water (Table 13).
June 1973
By June 1973 the lakewide biomass had increased to a mean of 3.0 gm dry
wt/m-^ (per unit volume), as shown in Table lU. Two large cells were
located in western Lake Ontario, centered upon stations 10 and 32. An
inshore cell was located west of Rochester, centered on station 5&>
and a high concentration of particles was observed in Mexico Bay. Again
the general principal of a predominantly deepwater distribution of
bicmass is evident (Figure 18).
Comparison with Previous Estimates of Zooplankton Biomass
Zooplankton biomass estimates for Lake Ontario were made by Watson (197M
from animals taken in vertical tows frcm 50 m to the surface (Table 15).
It is immediately obvious that our estimates are about lOOx those made
previously. This is because (a) the efficiency of net sampling, about
$, was not considered, and (b) because we have placed much of the
bicmass (estimated acoustically) below 50 m. It is necessary at this
time that our acoustical estimates be considered preliminary. But they
should provide a considerable stimulus to verify or deny the existence
of considerable zooplankton biomass at depths greater than 100 m in
Lake Ontario.

SECTION VII
COMPARATIVE MATHEMATICAL ANALYSIS OF ZOOPLANKION COMMUNITIES
INTRODUCTION
One of the important topics of ecology is the comparison of different
communities. Communities found in similar environments as well as
those occupying very different environments can be compared for species
composition, species interactions and mass and energy flow, as well as
other community properties. Comparison can "be descriptive and qualita-
tive, or some quantitative measures of community structure and the roles
of species can be developed.
This study utilizes the competition matrix by Levins (1968) as a model
from which to develop such measures. A very simple definition of
community is implied by this model, simply a group of species interacting
at a time and place — the question of whether the community is a
natural biological unit (Poole, 197^) is of no concern.
The use of the competition matrix restricts the concept of community
to a group of competitors and therefore to essentially one trophic
level. This study considers a community consisting of only the
dominant herbivorous zooplankters as the cladocerans, Daphnia galeata,
Daphnia longiremis, Bosmina, Diaphanosoma, and the calanoid copepods,
Diaptomus minutus and Diaptomus sicilis. Cmnivores and carnivores are
excluded from the model.
Three different levels of community structure are investigated with
measures developed from the competition matrix. First, the individual
interactions between species can be considered. Then the importance of
each species in terms of competition levels can be investigated. Finally,
at the community level, the average intensity of competition and
community stability can be studied.
Additional measures not directly related to the competition matrix are
also considered in this study. Niche breadths, as a property of species,
and community diversity, a community property, are essentially informa-
tion measures which can be applied to comparing communities.
Utilizing these measures of the entire community the following hypothesis
can be investigated: During the period between spring and fall turnovers
of the lake the zooplankton community evolves toward reduced competition,
increased stability and increased diversity.
The competition matrix is based on a model of interacting species first
used by Volterra (1926). This model has been given two interpretations.
First, it can be considered as a simple model of population dynamics in
6k
-------
its own right. Secondly, it can be viewed as an approximation to
certain more complex models in some region around equilibrium. It is
this latter interpretation which we are considering here with the
resulting limiting assumption that the community under consideration is
always in a near equilibrium state. For this reason the zooplankton
communities considered all occur at summer dates when the equilibrium
conditions are more nearly met.
MATHEMATICAL THEORY
Competition Matrix
The competition matrix arises from the Volterra (1926) system for m
interacting species
- -t* -
m
a n
ii
= 1; i = 1,2,-—m
(1)
where n. - population density of the ith species
Pi - intrinsic growth rate of the ith species
k. - carrying capacity of the ith species
cj. - competition coefficient jth species on the ith species
ay measures the number of individuals of species, i, displayed by one
individual of species, j, when the system is near equilibrium. The
Ojj can be grouped in an array known as the competition matrix (Levins,
19o8), This matrix, A , is of the form
a

end contains information on competition between individuals of different
species.
The o^.- measure the displacement of species i per individual of species
j. ItJis often of more interest to consider the displacement of species
i due to the entire population of species j. If we let n represent the
equilibrium population of species j, then 0: .=6. would be a measure of
this displacement. We can think of this as weighting each element a..
by the population density n.. In order that the new elements be scaled
similarly to c^ ., a normalizing factor (n"ave)~1j where navg = - j. n ,
j=l
-------
is used and an adjusted competition matrix A is formed with elements
n
eve
(3)
These elements indicate the relative competitive impact of species j
on species i.
While a comparison of communities can be made using the «. . or a1..
values directly, data reduction techniques can often facilitate the
analysis. A number of these techniques are based on averaging over
the competition matrix in different fashion.
Vandermeer (I9?2a) suggested two approaches. First is the row average,
which he termed the community effect. It measures the competition
faced by a species. The ith row average,, <^. (or "..), is defined as
a £lj a
1 m 3=1 lj
(where _A_ means "is defined as")
A second measure is the column average, termed the species effect.
This is defined as
m
1 E
a-jA.*i=1aij (5)
and similarly for a^.. This measures the impact of a species on the
community, a. . can oe written
ave
and considered to be a normalized effective population density (normal-
ized by navg), where effective refers to competitive impact. This
measure is useful in rank ordering species in terms of their importance
in the community as a function of competition.
Eow and column averages are species' properties and can be used in
comparing the roles of species within and between communities. Another
species measure, not a function of the a's, is niche breadth. If
species i has a one dimensional niche divided into r micro-environments
66
-------
and pik is the proportion of the species utilizing the kth environment,
then
Z Pik
k-1
is a measure of niche breadth (Levins, 1968). For a two dimensional
niche such as is used in this study the relationship becomes
(8)
k=U=l
If the two dimensions are independent equation (8) can be written
Properties of whole communities can be measured as well. Levins (1968)
suggested the average a as s measure of niche separation in the community.
This parameter,
m m
m
is a measure ofnaverage species co-occurrence in Levins' original
formulation. "& , analogous to "3, is a community measure of competition
in the present formulation.
Diversity is another example of a community property_and is often
measured by the Shannon-Weaver information measure, d, community diver-
sity, is defined as
_ m n. n
d A . r J ln J (11)
-------
Utilizing a^ es a' weighted version of n., a second diversity index, cP-,
can be formed in a way analogous to equation (11).
We now have four community measures, a" depends on niche structures and
is essentially independent of population densities, d, on the other
hand, is a measure of population densities and does not depend on niche
structure. "$• and c£ are both mixed measures, including information
on niche structure and population densities.
System Matrix
If we are interested in the dynamics of a cctnmunity in a near equilibrium
state and particularly in its local stability, analysis of the system
matrix is required. To determine this matrix the system is linearized
around its equilibrium point. The linearized system is
m
- n.j); 1 - 1,2,— m (12)
where the a^. ere defined as
oi. . ^ a ^ p. m
anj v ^
The resultant value of a. is
n n .

The aij form the elements of A, the system matrix. A and A* are
relates by a simple matrix transformation. If D is a diagonal matrix
(all zeros except along the main diagonal) and the diagonal elements
are d.± = - Pjni , then A = DA.
Equation (12) can be re-written in matrix form as
n = A(n - n) (15)
68
-------
The solution for n - n, valid only near n, is of the form
, t
m Ak
n - n - z c.
.
(16)
Where the m values ^k, knov/n as the eigenvalues of the system matrix A,
are the roots of the equation
Ml|= 0. (17)
I is the identity matrix and U-A.l| is the determinant of A-AI.
The stability of the equilibrium depends on the eigenvalues. If any
A^ has a positive real part the equilibrium is unstable. Thus, if we
designate by ^j^,. the eigenvalue with the largest real part, A seems
a good measure of community stability (May, 1973). We shall return to
this point later.
The Competition Coefficient
Basic to both the competition matrix and the system matrix is the
competition coefficient. Levins (1968) initially used as an approxima-
tion to competition the probability of co-occurrence, essentially a
niche overlap model of competition. Levins (Lane, 1971) and others
(MacArthur, 1972; May, 1973; Schoener, 197^; Yandermeer, 1972b) have
discussed other forms of niche overlap models. This study will utilize
a rather simple form.
Assume initially a one dimensional resource spectrum, R]_, i^j lL> where
I?k is the equilibrium density (or standing crop) of the kth resource
group. Let <)>., be the rate per unit density at which species i utilizes
resource k. Then ^ R, $ ,

be expressed as s.p., where •; p = 1.

The model developed for herbivorous zooplankton considers a two-
dimensional resource spectrum (or niche). These dimensions are known
as habitat selection and resource allocation (Lane, 1971). Habitat
selection refers to the vertical distribution of zooplankton species
in the water column and overlap in this niche dimension is co-occurrence.
Resource allocation refers to size-selective feeding by the zooplankton
(Burns, 1968; Wilson, 1973). In turn the density of the resources,
largely phytoplankton, must be described in terms of both vertical
distribution and size distribution. The resource is now described as

SECTION VIII
A HYPOTHESIS ON CALANOID SUCCESSION TO CLADOCERANS
DURING EUTROPHICATION
INTRODUCTION
Changes in the species composition of the crustacean zooplankton have
long been used as an indication of the Increased eutrophication of
freshwaters. The best known indicator, Bosmina longirostris, was
observed to replace the larger B. coregoni after 50 years of enrichment
of the Zurichsee (Minter, 1938). B. longirostris likewise replaced
B. coregoni in Linsley Pond following a period of increased productivity
TDeevey, 19^2).
In the Laurentian Great Lakes a complicated series of changes have been
detailed. In Lake Michigan the cladocerans Daphnia retrocurva and
D. galeata dominated in 1927 (Brooks, 1969) and 195^ (Wells, I960),
gave way to the smaller and likely more predation-free D. longiremis
by 1966, while D. retrocurva was again dominant by 1968~~(wells, 1970).
Likewise, Leptodora kindtii, the largest cladoceran, was common in
195^-j rare in 1966 and common again by 1968, as were the large calanoids
Limnocalanus macrurus, Epischura lacustris, and Diaptomus sicilis
(Wells, I960 and 1970). Such data have been interpreted as a response
to high alewife predation through 1966 (Brooks, 1969), with a return
to 195^-like populations following the alewife dieoff after 1966 (wells,
1970). By 1972, Bosmina longirostris and Cyclops bicuspidatus were
dominant (Roth and Stewart, 1973)-
Similarly, in Lake Ontario Diaptomus and Daphnia were abundant in 1939>
whereas Cyclops bicuspidatus and Bosmina longirostris took over as in
Lake Michigan by 1969 (McNaught and Buzzard, 1973).Bosmina is now
especially abundant inshore and nearby urban areas (McNaught, 197*0-
In Lake Erie similar communities were dominated by D. galeata in 1938,
with D. retrocurva second (Chandler, 19^-0), whereas by 1959 the smaller
D. retrocurva had succeeded (Bradshaw, 196i). Again we could have
interpreted these observations as evidence of size-selective predation,
but in my opinion the size spectrum of food resources must also be
considered.
Clearly a better understanding of eutrophication will result from a
greater knowledge of selective factors governing changes in species
composition. Brooks (1969) has suggested that, in addition to enrich-
ment, planktivory by fishes and zooplankton filtering capacity are
primary factors in species succession. But additional factors under
two following headings are also vital; all emphasize the nutritional
aspects of a nutritionally dilute environment:
71
-------
I. Evolutionary responses to variable phytoplankton foods.
A. evolution of generalists and specialists with regard to
selective algal grazing by zooplankton
B. evolution for increased filtering capacity
C. evolution for increased ingestion rate and efficiency,
both by size and density of algae
D. evolution toward increased efficiency of digestion
II. Evolutionary responses to fish predation.
A. evolution for small adult size at maturity
B. evolution of biotic potential (r-selection organisms with
high intrinsic Mrth rates (b.^) °r low death rates)
C. evolution for reduced visibility, especially of larger
adults.
EVIDENCE FCE EVOLUTIONARY TRENDS
From studies of zooplankton feeding it has been evident that some
oligotrophic forms are nannoplankton specialists, while many eutrophic
species are generalists. But little argument exists regarding whether
zooplankton are size-selective feeders. Calanoid copepods are special-
ists on nannoplankton, as confirmed by field studies. Eudiaptomus in
Lake Erken preferred nannoplanktonic chrysomonads (Nauwerck, 1963).
Similarly 70$ of the diet of Diaptomus consisted of phytoplankton of
less than 6% diameter in one study (Lane, 1971), while in another
most was less than 22y (Bogdan and McNaught, 197^). In contrast,
Bosmina longirostris had a preferred range of particles in the nanno-
plankton category (1 - 15y ) according to Gliwicz (1969), but has also
been observed to consume a sizeable percentage (50$) of cells above
6Uy (Lane, 1971). These differences in size will be used to calculate
grazing (Table 16).
Thus each organism has been given an adaptive value within the framework
of lake productivity. In actual application here, the relative values
for each of the 8 components to which the zooplankton show adaptation
are summed to determine the adaptive value. The 8 components had
relative values from 5 to 100 and the resulting adaptive values for
Diaptanus. Daphnia and Bosmina range from 3^ to 642 (Table Ib).
The advantages of increased filtering capacity were discussed by Brooks
(1969), who found that filtering capacity increased as the square of
body length (Brooks and Dodson, 1965). Indeed.the larger Daphnia
filtered nannoplankton at the same rate as Diapt-omus (Table 16), while
Bosmina longirostris lagged on all resources (Bogdan,197^). Dodson
(1974) has suggested that the advantages of size and filtering capacity
alone were not enough to insure survival.
The efficiency of ingestion appears 'to be a dominant factor in contrasting
the evolution of feeding. .Studies by McMahon and Rigler (1963) on

Daphnia magne and Richman (1966) on Diaptomus oregonensis have been
compared (Figure 19). The ingestionrate (Ij.) has been described by
the above authors in terms of cells ingested, where:
Ir = ceils ingested/animal/day
Thus Diaptcmus feeding in a concentration of cells characteristic of
oligotrophic lakes (925 cells/ml), ingested cells at a rate of 1800
cells/an/day (Figure 19). Daphnia, filtering at similar rates, would
ingest only ^00 cells/an/day. In contrast, at an mesotrophic concentra-
tion of 2600 cells/ml, these graphs would indicate an ingestion rate
for Diaptomus of 5000 cells/an/day, while Daphnia would ingest 1300
cells/an/day. Clearly at oligotrophic and mesotrophic concentrations
of planktonic algae, Diaptomus has a higher ingestion rate (Figure 19).
Diaptcmus thus has a higher ingestion efficiency at low densities, in
these experiments, Daphnia was fed yeast and Diaptomus algae. While
more such efficiencies must be determined for natural assemblages,
these comparative results suggest that Diaptcmus is adapted to existing
on a more dilute food source than Daphnia, which is better adapted to
the rigors of life in eutrophic waters, with its highly developed
respiratory system.
Just recently, Bogdan and McWaught (197*0 have examined ingestion
efficiency with regard to the size of algal foods. Diaptomus, the
nannoplankton specialist, is three times more efficient on nannoplankton
(.016) than netplankton (.005), tut Daphnia, the generalist, was
equally efficient on both (.065 and .062). These findings again suggest
Diaptcmus to be well adapted to oligotrophy.
The last nutritional item, the evolution of the efficiency of digestion,
relates to both the size and packaging of the algae resource, Recently
Porter (1973) has found that green algae encased in thick gelatinous
sheaths pass the gut of Daphnia galeata in viable condition. Much needs
to be done relating the efficiency of digestion to size, packaging,
available digestive enzymes, etc. and this parameter will not be given
a value here.
Growth related responses have likely evolved with regard to fish
predation. Evolution toward smell size of the adult at the time of
first brooding is of considerable benefit under heavy predation. We
have examined the size of Diaptomus sicilis (1.6 mm), Daphnia galeata
(1.0 ma), and Bosmina longirostris (0.26 mm) at the time of first
birth. Quite obviously, Bosmina has a considerable advantage in this
regard. Within genera, certain species also have an advantage, as
•§• lopgirostris is smaller than B. coregoni (0.5 mm) of oligotrophic
waters, possibly one of the important factors explaining the often
noted succession between these two species.
In a similar fashion, r-selection organisms can withstand considerable
predatory pressure through a high intrinsic growth rate. Additionally,
selection for high growth rate (r) in planktonic organisms has enabled

a rapid response to resource explosion. Our species have been calibrated
using field data for Daphnia galeata (Hall, 19§^) and Diaptomus and
Bosmina longirostris (McNaught, unpublished). The significantly lower
maximum birth rate for Diaptomus (Tablel6) will likely become a limiting
factor under eutrophic conditions.
Once the organismic factors had been described (Table 16, Section l),
we proceed to give them relative values. However, it must be noted that
individual feeding and growth factors have not been weighted. In
nature some are certainly more important than others. In many cases,
specific values for high or low foods were available. Potentially
adaptive characteristics have been summarized (Table 16) by actual and
relative value.
POPULATION GROWTH AMD GRAZING
Determination of relative population growth and grazing in Lake Superior
served as the calibration for our oligotrophic lake. During August
three species of Cyclotella constituted 76$ by density of the phyto-
plankton (Schelske, et al. 1972) and ranged in size from 2.5y to 15p
in diameter. The remaining algae were predominantly flagellates. Thus
the bulk of the phytoplankton was less than 15M and fell in the 1 - 22|i
category (Stoermer,1973) while cell densities ranged from 350 - 1500
cells/ml.
Lake Ontario is the mesotrophic example. In August, the time of maximum
phytoplankton standing crop, the plankton is evenly composed of chloro-
phytes (38$), cyanophytes (3^), cryptomonads (12$)j dinoflagellates (12$)
and chryscmonads (U$) (Munawar and Nauwerck, 1971). These forms ranged
in size from 2 - 137^ in diameter, with almost all between 2 - 65y ,
and the largest sub group of these between 2 - 22y
To determine grazing, on an individual basis for each species, we have
simply multiplied filtering rate (F) times the efficiencies for
ingestion with size (Eg), times the ingestion rate (l) times the
standing crop of phytoplankton (%>), for Lake Superior within the 1 - 22U
size category (925 cells/ml) and for Ontario (Stoermer, 1973) within
the 1 - 22P (1300 cells/ml) and 22 - 65y (1300 cells/ml) categories.
This calibration suggests more Bosmina when netplankton is abundant,
as Hrblcek et al. (I96l) have observed. Thus relative grazing (G)
is denoted;
G - F • Ip • Eg • Kp (21)
To determine net production, we used the exponential growth equation:
IT = N ert (22)
to v '
where N = number at time t, K = number at the onset, and r = the
intrinsic growth rate. Furthermore:
r = b - d
76
-------
where intrinsic birth rates (b) were used as designated in Table 7, and
death rates for Diaptomus (0,10 ind/ind/day), Daphnia (0.5 ind/ind/day),
and Bosmina (0.01 ind/ind/day) were based relative to size. Fish preda-
tion was considered negligible in Lake Superior, and high in Lake Ontario.
Production was calculated for e period of 10 days, to illustrate the
potential of these populations. Then to determine the impact of grazing,
we simply multiplied the individual grazing rate (G) times herbivore
abundance (K). As opposed to the organismic subtotal of relative values,
we have termed this the Production-Grazing subtotal (Table 16, Section II).
Once each of these factors of evolutionary significance had been assigned
a relative value, we applied the non-parametric Wilcoxon's paired, signed
ranks test (Sokol and Rohlf, 19&9) to see whether one column (components
of adaptation for a species) was significantly different from another.
Under oligotrophic conditions, Diaptcmus totaled kSi pts., but was not
significantly better adapted than Bosmina with ^01 pts. (T = 11, p^O.l);
on the other hand, Daphnia was better adapted (T = 0, p<0.1) than
Bosmina. Under mesotrophic conditions, Daphnia was significantly
(T = 6, p<0.1) better adapted than Diaptomus, while Bosmina was not
(T = 9, p>0.1).
CONCLUSIONS
The sum total of all relative Organismic and Production-Grazing subtotals
has been called the Adaptation Value (Table 16). These Adaptation Values
suggest that Diaptomus would be successful in an oligotrophic lake like
Superior, because of its superior filtering capacity and its high inges-
tion rate at low cell densities and high ingestion efficiency at small
cell sizes. Bosmina was not predicted successful under similar condi-
tions, because of its low filtering capacity.
In contrast, in mesotrophic Lake Ontario the feeding generalist, Bosmina,
was predicted successful because of its ingestion efficiency on small and
large cells alike, its small size at maturity, which reduces fish preda-
tion and its high intrinsic birth rate (bm=x). Indeed, Diaptomus sicilis
is the dominant organism in Lake Superior (Patalas, 1969)> and occurs in
all of the Great Lakes (Robertson, 1966), while Bosmina longirostris
dominates in Lake Ontario (McWaught and Buzzard, 1973).
However, in both trophic simulations Daphnia was predicted more success-
ful than observed in nature, due to its high filtering capacity, high
ingestion efficiency on both small and large cells, and its high intrinsic
birth rate. Clearly we have more to consider in this case, and possibly
fish predation upon Daphnia has been undervalued. Also, Daphnia retro-
curva and Diaptomus have been observed to co-occur, made possible through
resource allocation (Lane and McNaught, 1973).
Regarding zooplankton succession, we have added the important concepts
of ingestion rate with the size of food, and ingestion efficiency with
the density of algae, to Brooks (1969) emphasis upon filtering capacity.
Further investigation of feeding habits should detail the successes in
the Great Lakes of species like Daphnia retrocurva, leading to a better
understanding of eutrophication.

18. ABSTRACT
The Crustacean zooplankton are excellent indicators of environmental perturbation,
especially if enough of their biology is known to explain why certain species
increase with nutrient enrichment of lakes. The distribution of zooplankton
in Lake Ontario suggested that eutrophic indicators were found in the vicinity
of major urban centers.* Furthermore, mathematical indices, including diversity,
the community competition coefficient, and carrying capacity, separated urban
inshore from rural inshore waters, further evidence of perturbation. Biomass
estimates made with new acoustical techniques indicated that most of the
zooplankton biomass was in deep waters, thus the eutrophication of Ontario's
waters, both nearshore and in the vicinity of cities, is still localized in
nature. Mathematical techniques have been developed to model such perturbations.
The report was submitted in fulfillment of an EPA project, Grant No. 800536,
by the State University of New York at Albany under the sponsorship of The
Environmental Protection Agency. Work was completed as of 15 August
*The ratio of the number of Bosmina longirostris, the most successful eutrophic
species, to Diaptomus sicilis, the most oligotrophic form,supported this
conclusion.
