Meeting Abstract 23.4 Friday, Jan. 4 Natural Neuroprotection in the Brains of Marine Mammals: Why swimming dolphins don�t stroke WILLIAMS, T.M.**; ZAVANELLI, M.; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz williams@biology.ucsc.edu Whereas neural impairment in human drowning victims can occur within a few minutes of submergence, extreme mammalian divers, most notably Weddell seals (Leptonychotes […]
Extreme starvation tolerance in snakes What makes them so different from other vertebrates
Meeting Abstract 23.3 Friday, Jan. 4 Extreme starvation tolerance in snakes. What makes them so different from other vertebrates? MCCUE, Marshall D; University of Arkansas mmccue@uark.edu Many snakes demonstrate the ability to survive periods of fasting that can last in excess of one year � a feat rarely matched by other vertebrates. Here I present the results […]

Hormonally-mediated maternal effects the mothers perspective
Meeting Abstract 22.3 Thursday, Jan. 3 Hormonally-mediated maternal effects � the mother�s perspective TRAVERS, M.*; CLINCHY, M.; WILLIAMS, T.D.; ZANETTE, L.; SFU & UWO; UWO; SFU; UWO mtravers@sfu.ca Hormonally-mediated maternal effects involve transfer of hormones from the mother�s circulation to offspring via egg yolk. Hormones that have potential �adaptive� effects in offspring also have important functional roles […]
