dc.description.abstract | Lab experiments were performed in the spring of 1995 at UMBS at Douglas Lake, Michigan to test the preference of freshwater clams for different substrates as well as current velocity. Experiments were performed with Ligumia nasuta, Anodonta grandis, and Lampsilis radiata siliquoidea, which commonly occur together in Douglas Lake. We do not believe that L. nasuta, A. complanata or L. r. siliquoidea frequently inhabit the stream areas surrounding Douglas Lake, which are commonly inhabited by the species Elliptio complanata. Using movement and feeding frequency as measures of fitness, we monitored the effects of varying currents and substrates on lake dwelling clams. We assumed increased feeding frequency and decreased movement to be proxies of fitness in different habitats. A positive relationship between increasing curent and clam movement supported our initial hypothesis that clams move significantly more when subject to higher current. We did not find any significant difference in feeding frequency betweeen substrates, however feeding increased significantly with increased velocity. Results from this study illustrate that variations in habitat may result in the enhanced fitness of clams. Species dispersal may be a result of different species' abilities to adapt to given habitat conditions. | en_US |
