Seasonal Diversities Of Lotic And Lentic Benthic Insect Populations, Jerry E. Bindel Jan 1977

Seasonal Diversities Of Lotic And Lentic Benthic Insect Populations, Jerry E. Bindel

Masters Theses

The benthic insect populations from Lake Charleston and the Embarras River above and below Lake Charleston were examined twice monthly for seasonal differences in number of organisms, number of taxa and species diversity from October 13, 1976 to February 16, 1977. The water quality parameters of alkalinity, carbon dioxide, dissolved oxygen, pH and temperature were also examined for each site to determine if any parameter showed a sufficient deviation as to exert an influence on the benthic insect populations. Low dissolved oxygen and high carbon dioxide values were noted and occurred at times corresponding to lower numbers of taxa and …
