Meeting Abstract 64.1  Thursday, Jan. 6  Dip Listening: Do Frogs Do It? VELEZ, A.*; BEE, M.A.; University of Minnesota – Twin Cities velez011@umn.edu The background noise generated in dense social aggregations, such as choruses or crèches, places constraints on communication. We know relatively little about how nonhuman animals may be adapted to exploit various acoustic features of […]

Meeting Abstract 64.6  Thursday, Jan. 6  Biogenic amine receptor gene expression in the immune system and nervous system of the Texas field cricket (Gryllus texensis) EASY, Russell H.*; ADAMO, Shelley A.; Dalhousie University; Dalhousie University reasy@dal.ca The biogenic amine octopamine regulates behaviour, mediates the stress response, and modulates immune function in insects. Tyramine is the synthetic precursor […]

Meeting Abstract 64.5  Friday, Jan. 6  A single, stepwise origin of ectolecithality in Platyhelminthes? LAUMER, C.E.*; GIRIBET, G.; Harvard Museum of Comparative Zoology; Harvard Museum of Comparative Zoology claumer@oeb.harvard.edu Ectolecithality is a process of functionally and (usually) spatially divided oogenesis that effects distinct populations of vitelline cells and nearly-yolkless germ cells. The origin of ectolecithality may have […]
