Abstract: Recent studies on stream drift, or the downstream transport of organisms, has shown a variety of different mechanisms that affect the way an organism drifts.  Most of this research has been done on invertebrates, with very little on vertebrates, such as aquatic salamanders.  I proposed that water velocity is an important factor in the drift of two species of larval salamanders: Desmognathus quadramaculatus (both small and large size classes) and Eurycea cirrigera (only small size class).  Since both species have two distinct size classes present in the stream, it was proposed that differences in movement based on size and/or species would also occur.  To conduct this experiment, two artificial streambeds, with differing levels of water velocity, were used.  The levels of water velocity used in the experiment treatments did not have a different affect on the movement of organisms.  Since downstream movement of all animals was quite common, this implies that drift has occurred.  There were significant differences in the amount of movement of large D. quadramaculatus and small E. cirrigera, implying that the combined differences in species and size are a factor in larval movement.  Determining the mechanisms for larval drift is important for defining salamander populations in an aquatic community.
