Caddisfly larvae weave nets between coarse sediment grains on river beds, which increase the fluid shear stress necessary to initiate sediment motion. I am collaborating with UCSB biologists in a series of laboratory experiments at the UC Berkeley Richmond Field Station to measure the effect of multiple species on threshold of motion shear stress and bed sediment dynamics. These experiments are linked with field studies being conducted by Lindsey Albertson and Brad Cardinale at SNARL. In particular, we intend to use the field conditions of Caddisfly larvae density and preferred grain size distribution to guide our experimental design in the laboratory. This application is for access to the reserve to support Lindsey Albertson's ongoing field project and to make non-intrusive and complimentary observations.
