Limnological studies of lentic waters in Idaho: a comparison of crustacean populations and sampling techniques in four mountain lakes of Idaho. Research technical completion report, project A-018-IDA Item Info

Standing crop of microcrustaceans were compared in four mountain lakes in northeast Idaho. Results over two summers indicated that the lower meadow lakes had higher densities of crustaceans than the headwall lakes. These findings were based on vertical plankton hauls. Four different field methods of collection together with various sample sizes were also compared. Reliability of data was possibly affected by small sample sizes and avoidance behavior of the crustaceans to the samplers. The four lakes had a similar species composition and low density of crustaceans. Fisher's coefficient of dispersion s2/x-bar was computed for all samples and used as a measure of horizontal dispersion. Mean total crustacean density and dispersion approximated taxa density and dispersion. Tables and graphs are included.
