Title:
Aquatic environment and food habits of mayflies. Research technical completion report, project A-022-IDA
Authors:
Brusven, M. A.; Gilpin, B. R.
Date Created (ISO Standard):
1969-06
Description:
The food habits and ecology were studied for 31 species of mayfly nymphs from the St. Maries River in Idaho, during 1967 and 1968. Mayfly nymphs were basically herbivores, feeding on variable amounts of detritus, diatoms and filamentous algae; insects were occasionally consumed. The feeding habits depended largely on the microhabitat of the nymph, e.g. riffle species generally fed more on filamentous algae and diatoms while pool-inhabiting nymphs fed largely on detritus. Different age c:lasses of nymphs usually fed on the same relative composition of food. Nymphs of many mayfly species demonstrated similar microhabitat affinities, although the macrohabitats were often dissimilar. Bottom type and current speed were important factors limiting mayfly distribution. A dendrogram was used to correlate station similarities biotically; several diverse habitats supported the same species.
