Behavior response of an alpine lake copepod to thin layer structure
The objective of this study is to determine for the alpine copepod Hesperodiaptomus shoshone whether a) the species responds to hydromechanical cues in a manner similar to marine copepods, and b) if shear strain rate is an important cue in mating behavior. A free shear flow was simulated in the labo...
