MATE-SEARCHING BEHAVIORS IN THE FRESH-WATER CALANOID COPEPOD LEPTODIAPTOMUS ASHLANDI

Copepods are the major primary grazer in the Great Lakes of North America. To maintain their populations, copepods reproduce sexually fertilized eggs. Therefore, male and female copepods have to encounter each other for successful mating. Since they live in a three-dimensional environment, it is difficult to find each other. In marine calanoid copepods, males track females by chemoreception in combinations with behavior patterns (Doall et al. 1998). My question is: do fresh-water calanoid copepods find their mates in the same manner as the marine ones do? The animals were caught in the Lake Michigan, off-shore Milwaukee, kept in the laboratory until mature, sorted, and introduced to the 3D optical set-up of Strickler (1998). The results will be shown in a video.
