RESEARCH REPORTING SERIES
Research reports of the Office of Research and Development, U.S. Environmental
Protection Agency, have been grouped into nine series. These nine broad cate-
gories were established to facilitate further development and application of en-
vironmental technology. Elimination of traditional grouping was consciously
planned to foster technology transfer and a maximum interface in related fields.
The nine series are:
1. Environmental Health Effects Research
2. Environmental Protection Technology
3. Ecological Research
4. Environmental Monitoring
5. Socioeconomic Environmental Studies
6. Scientific and Technical Assessment Reports (STAR)
7. Interagency Energy-Environment Research and Development
8. "Special" Reports
9. Miscellaneous Reports
This report has been assigned to the ECOLOGICAL RESEARCH series. This series
describes research on the effects of pollution on humans, plant and animal spe-
cies, and materials. Problems are assessed for their long- and short-term influ-
ences. Investigations include formation, transport, and pathway studies to deter-
mine the fate of pollutants and their effects. This work provides the technical basis
for setting standards to minimize undesirable changes in living organisms in the
aquatic, terrestrial, and atmospheric environments.

FOREWORD
Protection of the environment requires effective regulatory actions
which are based on sound technical and scientific information. This infor-
mation must include the quantitative description and linking of pollutant
sources, transport mechanisms, interactions, and resulting effects on man
and his environment. Because of the complexities involved, assessment of
specific pollutants in the environment requires a total systems approach
which transcends the media of air, water, and land. The Environmental
Monitoring and Support Laboratory-Las Vegas contributes to the formation
and enhancement of a sound integrated monitoring data base through multi-
disciplinary, multimedia programs designed to:
• develop and optimize systems and strategies for moni-
toring pollutants and their impact on the environment
• demonstrate new monitoring systems and technologies
by applying them to fulfill special monitoring needs
of the Agency's operating programs
This report presents the species and abundance of phytoplankton in the
16 lakes sampled by the National Eutrophication Survey in the State of
Tennessee, along with results from the calculation of several commonly used
biological indices of water quality and community structure. These data
can be used to biologically characterize the study lakes, and as baseline
data for future investigations. This report was written for use by Federal,
State, and local governmental agencies concerned with water quality analysis,
monitoring, and/or regulation. Private industry and individuals similarly
involved with the biological aspects of water quality will find the document
useful. For further information contact the Water and Land Quality Branch,

INTRODUCTION
The collection and analysis of phytoplankton data were included in the
National Eutrophication Survey in an effort to determine relationships between
algal characteristics and trophic status of individual lakes.
•&
During spring, summer, and fall of 1973, the Survey sampled 250 lakes in
17 States. Over 700 algal species and varieties were identified and enumerated
from the 743 water samples examined.
This report presents the species and abundance of phytoplankton in the
16 lakes sampled in the State of Tennessee (Table 1). The Nyqaard's Trophic
State (Nygaard 1949), Palmer's Organic Pollution (Palmer 1969), and species
diversity and abundance indices are also included.

MATERIALS AND METHODS
LAKE AND SITE SELECTION
Lakes and reservoirs included in the Survey were selected through
discussions with State water pollution agency personnel and U.S. Environmental
Protection Agency Regional Offices (U.S. Environmental Protection Agency
1975). Screening and selection strongly emphasized lakes with actual or
potential accelerated eutrophication problems. As a result, the selection
was limited to lakes:
(1) impacted by one or more municipal sewage treatment plant outfalls
either directly into the lake or by discharge to an inlet tributary
within approximately 40 kilometers of the lake;
(2) 40 hectares or larger in size; and
(3) with a mean hydraulic retention time of at least 30 days.
Specific selection criteria were waived for some lakes of particular State
interest.
Sampling sites for a lake were selected based on available information
on lake morphometry, potential major sources of nutrient input, and on-site
judgment of the field limnologist (U.S. Environmental Protection Agency
1975). Primary sampling sites were chosen to reflect the deepest portion
of each major basin in a test lake. Where many basins were present, selection
was guided by nutrient source information on hand. At each sampling site,
a depth-integrated phytoplankton sample was taken. Depth-integrated samples
were uniform mixtures of water from the surface to a depth of 15 feet
(4.6 meters) or from the surface to the lower limit of the photic zone
representing 1 percent of the incident light, whichever was greater. If
the depth at the sampling site was less than 15 feet (4.6 meters), the
sample was taken from just off the bottom to the surface. Normally, a lake
was sampled three times in 1 year, providing information on spring, summer,
and fall conditions.
SAMPLE PREPARATION
Four nrilliliters (ml) of Acid-Lugol's solution (Prescott 1970) were
added to each 130-ml sample from each site at the time of collection for
preservation. The samples were shipped to the Environmental Monitoring and
Support Laboratory, Las Vegas, Nevada, where equal volumes from each site
were mixed to form two 130-ml composite samples for a given lake. One
composite sample was put into storage and the other was used for the
examination.
-------
Prior to examination, the composite samples were concentrated by the
settling method. Solids were allowed to settle for at least 24 hours prior
to siphoning off the supernate. The volume of the removed supernate and the
volume of the remaining concentrate were measured and concentrations determined.
A small (8 ml) library subsample of the concentrate was then taken. The
remaining concentrate was gently agitated to resuspend the plankton and
poured into a capped, graduated test tube. If a preliminary examination of a
sample indicated the need for a more concentrated sample, the contents of the
test tube were further concentrated by repeating the settling method. Final
concentrations varied from 15 to 40 times the original.
Permanent slides were prepared from concentrated samples after analysis
was complete. A drop of superconcentrate from the bottom of the test tube
was placed in a ring of clear Karo®Corn Syrup with phenol (a few crystals of
phenol were added to each 100 ml of syrup) on a glass slide, thoroughly
mixed, and topped with a coverglass. After the syrup at the edges of the
coverglass had hardened, the excess was scraped away and the mount was
sealed with clear fingernail polish. Permanent diatom slides were prepared
by drying sample material on a coverglass, heating in a muffle furnace at
400 C for 45 minutes, and mounting in Hyrax®. Finally, the mounts were
sealed with clear fingernail polish.
Backup samples, library samples, permanent sample slides, and
Hyrax-mounted diatom slides are being stored and maintained at the
U.S. Environmental Monitoring and Support Laboratory-Las Vegas.
EXAMINATION
The phytoplankton samples were examined with the aid of binocular
compound microscopes. A preliminary examination was performed to precisely
identify and list all forms encountered. The length of this examination
varied depending on the complexity of the sample. An attempt was made to
find and identify all of the forms present in each sample. Often forms were
observed which could not be identified to species or to genus. Abbreviated
descriptions were used to keep a record of these forms (e.g., lunate cell,
blue-green filament, Navicula #1). Diatom slides were examined using a
standard light microscope. If greater resolution was essential to accurately
identify the diatoms, a phase-contrast microscope was used.
After the species list was compiled, phytoplankton were enumerated using
a Neubauer Counting Chamber with a 40X objective lens and a 10X ocular lens.
All forms within each field were counted. The count was continued until a
minimum of 100 fields had been viewed, or until the dominant form had been
observed a minimum of 100 times.

QUALITY CONTROL
Internal quality control checks on species identifications and counts
were performed on a regular basis between project phycologists at the rate
of 7 percent. Although an individual had primary responsibility for analyzing
a sample, taxonomic problems were discussed among the phycologists.
Additional quality control checks were performed on the Survey samples
by Dr. 6. W. Prescott of the University of Montana at the rate of 5 percent.
Quality control checks were made on 75 percent of these samples to verify
species identifications while checks were made on the remaining 25 percent
of the samples to verify genus counts. Presently, the agreement between
quality control checks for species identification and genus enumerations is
satisfactory.
-------
RESULTS
The Appendix summarizes all of the phytoplankton data collected from
the State by the Survey. It is organized by lake, including an alphabetical
phytoplankton species list with concentrations for individual species given
by sampling date. Results from the application of several indices are
presented (Nygaard's Trophic State, Palmer's Organic Pollution, and species
diversity and abundance). Each lake has been assigned a four digit STORET
number. [STORET (STOrage and RETrieval) is the U.S. Environmental Protection
Agency's computer system which processes and maintains water quality data.]
The first two digits of the STORET number identify the State; the last two
digits identify the lake.
NYGAARD'S TROPHIC STATE INDICES
Five indices devised by Nygaard (1949) were proposed under the assumption
that certain algal groups are indicative of levels of nutrient enrichment.
These indices were calculated in order to aid in determining the surveyed
lakes' trophic status. As a general rule, Cyanophyta, Euglenophyta, centric
diatoms, and members of the Chlorococcales are found in waters that are
eutrophic (rich in nutrients), while desmids and many pennate diatoms
generally cannot tolerate high nutrient levels and so are found in oligotrophic
waters (poor in nutrients).
In applying the indices to the Survey data, the number of taxa in each
major group was determined from the species list for each sample. The
ratios of these groups give numerical values which can be used as a biological
index of water richness. The five indices and the ranges of values established
for Danish lakes by Nygaard for each trophic state are presented in Table 2.
The appropriate symbol, (E) eutrophic and (0) oligotrophic, follows ea ch
calculated value in the tables in the Appendix. A question mark (?) was
entered in these tables when the calculated value was within the range of
both classifications.
PALMER'S ORGANIC POLLUTION INDICES
Palmer (1969) analyzed reports from 165 authors and developed algal
pollution indices for use in rating water samples with high organic pollution.
Two lists of organic pollution-tolerant forms were prepared, one containing
20 genera, the other, 20 species (Tables 3 and 4). Each form was assigned
a pollution index number ranging from 1 for moderately tolerant forms to 6
for extremely tolerant forms. Palmer based the index numbers on occurrence
records and/or where emphasized by the authors as being especially tolerant
of organic pollution.

In analyzing a water sample, any of the 20 genera or species of algae
present in concentrations of 50 per milliliter or more are recorded. The
pollution index numbers of the algae present are totaled, providing a genus
score and a species score. Palmer determined that a score of 20 or more for
either index can be taken as evidence of high organic pollution, while a
score of 15 to 19 is taken as probable evidence of high organic pollution.
Lower figures suggest that the organic pollution of the sample is not high,
that the sample is not representative, or that some substance or factor
interfering with algal persistence is present and active.
SPECIES DIVERSITY AND ABUNDANCE INDICES
"Information content" of biological samples is being used commonly by
biologists as a measure of diversity. Diversity in this connection means the
degree of uncertainty attached to the specific identity of any randomly
selected individual. The greater the number of taxa and the more equal their
proportions, the greater the uncertainty, and hence, the diversity (Pielou
1966). There are several methods of measuring diversity, e.g., the formulas
given by Brillouin (1962) and Shannon and Weaver (1963). The method which is
appropriate depends on the type of biological sample on hand.
Pielou (1966) classifies the types of biological samples and gives the
measure of diversity appropriate for each type. The Survey phytoplankton
samples are what she classifies as larger samples (collections in Pielou1s
terminology) from which random subsamples can be drawn. According to Pielou,
the average diversity per individual for these types of samples can be
estimated from the Shannon-Wiener formula (Shannon and Weaver 1963):
H = -I P1 logx PI
1 = 1
where P is the proportion of the ith taxon in the sample, which is calculated
from n./N; n- is the number of individuals per milliliter of the ith taxon;
N is trie total number of individuals per ml; and S is the total number of
taxa.
However, Basharin (1959) and Pielou (1966) have pointed out that H
calculated from the subsample is a biased estimator of the sample H, and if
this bias is to be accounted for, we must know the total number of taxa
present in the sample since the magnitude of this bias depends on it.
Pielou (1966) suggests that if the number of taxa in the subsample falls
only slightly short of the number in the larger sample, no appreciable error
will result in considering S, estimated from the subsample, as being equal to
the sample value. Even though considerable effort was made to find and
identify all taxa, the Survey samples; undoubtedly contain a fair number of
rare phytoplankton taxa which were not encountered.
-------
In the Shannon-Hiener formula, an increase in the number of taxa and/or
an increase in the evenness of the distribution of individuals among taxa
will increase the average diversity per individual from its minimal value of
zero. Sager and Hasler (1969) found that the richness of taxa was of minor
importance in determination of average diversity per individual for phytoplank-
ton and they concluded that phytoplankton taxa in excess of the 10 to 15 most
abundant ones have little effect on H, which was verified by our own calcula-
tions. Our counts are in number per milliliter and since logarithms to the
base 2 were used in our calculations, H is expressed in units of bits per
individual. When Individuals of a taxon were so rare that they were not
counted, a value orl/130 per mill liter or 0.008 per mililiter was used in
the calculations since at least one individual of the taxon must have been
present in the collection.
A Survey sample for a given lake represents a composite of all phytoplank-
ton collected at different sampling sites on a lake during a given sampling
period. Since the number of samples (M) making up a composite is a function
of both the complexity of the lake sampled and its size, it should affect the
richness-of-taxa component of the diversity of our phytoplankton collections.
The maximum diversity (MaxH) (i.e., when the individuals are distributed
among the taxa as evenly as possible) was estimated from logo S, the total
diversity (D) was calculated from HN, and the evenness component of diversity
(J) was estimated from H/MaxH (Pielou 1966). Also given in the Appendix are
L (the mean number of individuals per taxa per milliliter) and K (the number
of individuals per milliliter of the most abundant taxon in the sample).
land (1976) suggests that diversity indices be expressed in units of
"sits", i.e., in logarithms to base S (where S is the total number of taxa in
the sample) instead of in "bits", i.e., in logarithms to base 2. Zand points
out that the diversity index in sits per individual is a normalized number
ranging from 1 for the most evenly distributed samples to 0 for the least
evenly distributed samples. Also, it can be used to compare different
samples, independent of the number of taxa in each. The diversity in bits
per individual should not be used in direct comparisons involving various
samples which have different numbers of species. Since MaxH equals log S,
the expression in sits is equal to logs S, or 1. Therefore diversity in sits
per individual is numerically equivalent to J, the evenness component for the
Shannon-Wiener formula.
SPECIES OCCURRENCE AND ABUNDANCE
The alphabetic phytoplankton species list for each lake, presented in
the Appendix, gives the concentrations of individual species by sampling
date. Concentrations are in cells, colonies, or filaments (CEL, COL, FIL)
per milliliter. An "X" after a species name indicates the presence of the
species on that date in such a low concentration that it did not show up in
the count. A blank space indicates that the organism was not found in the
sample collected on that date. Column S is used to designate the examiner's
subjective opinion of the five dominant taxa in a sample, based upon relative
size and concentration of the organism. The percent column (%C) presents, by
abundance, the percentage composition of each taxon.

APPENDIX. SUMMARY OF PHYTOPLANKTON DATA
This appendix was generated by computer. Because it was only possible
to use upper case letters in the printout, all scientific names are printed
in upper case and are not italicized.
The alphabetic phytoplankton lists include taxa without species names
(e.g., EUNOTIA, EUNOTIA #1, FLAGELLATE, FLAGELLATES, MICROSYSTIS INCERTA ?,
CHLOROPHYTAN COCCOID CELLED COLONY). When species determinations were not
possible, symbols or descriptive phrases were used to separate taxa for
enumeration purposes. Each name on a list, however, represents a unique
species different from any other name on the same list, unless otherwise
noted, for counting purposes.
Numbers were used to separate unidentified species of the same genus. A
generic name listed alone is also a unique species. A question mark (?) is
placed immediately after the portion of a name which was assigned with uncer-
tainty. Numbered, questioned, or otherwise designated taxa were established
on a lake-by-lake basis; therefore NAVICULA #2 from lake A cannot be compared
to NAVICULA #2 from lake B. Pluralized categories (e.g., FLAGELLATES, CENTRIC
DIATOMS, SPP.) were used for counting purposes when taxa could not be properly
differentiated on the counting chamber.
