Abstract |
The study determines the kinds and amounts of riparian leaves entering Doe Run, Meade County, Kentucky; determines the calorific equivalents of the different kinds of leaves entering the stream; documents whatever seasonal differences occur within species, determines the amounts of protein, carbohydrate, and lipid materials present in the different kinds of leaves; notes seasonal changes in those amounts; and determines the rates of loss of protein, carbohydrate, and lipid materials from leaves submersed in the stream over extended periods of time. Some quantitative and qualitative relationships between the streambank vegetation and the species composition of the leaves entering Doe Run were studied. Also, preliminary studies were made of the preference of different kinds of leaves by the indigenous amphipod Gammarus bousfieldi. |
