Meeting Abstract S3-11  Thursday, Jan. 5 15:00 – 15:30  The search for mechanisms underlying evolutionary trade-offs in response to different selection pressures in the least killifish CRESPI, E. J.*; TRAVIS, J. A.; Washington State University; Florida State University erica.crespi@wsu.edu http://public.wsu.edu/~erica.crespi/Home.html Evolutionary theory predicts that natural selection acts to maximize fitness by optimizing a life history that includes […]

Meeting Abstract S3-9  Thursday, Jan. 5 14:00 – 14:30  The Role of GnIH in the Tradeoff Between Reproductive and Ingestive Behavior SCHNEIDER, Jill E.*; BENTON, Noah; RUSSO, Kim; BROZEK, Jeremy; KRIEGSFELD, Lance; Lehigh University; University of California, Berkeley audryfarber@gmail.com Adaptation requires successful reproduction, but reproductive processes are energetically expensive and can compromise the chances of survival during […]

Meeting Abstract S3-10  Thursday, Jan. 5 14:30 – 15:00  The Effects of Food Availabilty on the Maternal and Sociosexual Behaviors of Meadow Voles FERKIN, M.H.; University of Memphis mhferkin@memphis.edu https://umdrive.memphis.edu/mhferkin/public/index.htm Many female small mammals, such as meadow voles, Microtus pennsylvanicus , may face limited food availability during behavioral estrus, pregnancy, postpartum estrus and lactation. The amount of […]

Meeting Abstract S3-4  Thursday, Jan. 5 09:30 – 10:00  Neuroendocrine control of the seasonal switch from reproduction to foraging in garter snakes LUTTERSCHMIDT, D.I.; Portland State University, OR d.lutterschmidt@pdx.edu Many vertebrates exhibit distinct life-history stages that are associated with specific physiological and behavioral functions, such as reproduction, migration, and foraging. In seasonal organisms, resource availability relegates these […]

Meeting Abstract S3-6  Thursday, Jan. 5 11:00 – 11:30  Neural versus gonadal GnIH: Are they independent systems? BENTLEY, GE; UC Berkeley gb7@berkeley.edu Gonadotropin−inhibitory hormone (GnIH) acts to inhibit reproduction at all levels of the hypothalamo−pituitary−gonad (HPG) axis. For example, GnRH neurons express GnIH receptor and decrease firing in response to GnIH application. The anterior pituitary gland of […]

Meeting Abstract S3-1  Thursday, Jan. 5 08:00 – 08:30  Neural circuitry that mediates behavior governing the tradeoffs between survival and reproduction in Caenorhabditis elegans EMMONS, S.W.; Albert Einstein College of Medicine scott.emmons@einstein.yu.edu http://worms.aecom.yu.edu Though C. elegans is a tiny, 1mm, nematode with fewer than 400 neurons in its nervous system, it nevertheless faces the same challenges of […]

Meeting Abstract S3-3  Thursday, Jan. 5 09:00 – 09:30  How do maternal programming strategies differ in the Syrian hamster, a seasonal breeder? BROZEK, J TBA

Meeting Abstract S3-5  Thursday, Jan. 5 10:30 – 11:00  Food Supply and the Timing of Reproduction DEVICHE, P.J.*; BITTNER, S.; GAO, S.; VALLE, S.; Arizona State University; Arizona State University; Arizona State University; Arizona State University deviche@asu.edu The timing of reproduction generally is a critical component of fitness and is related to trophic resources. Ultimately, reproduction is […]
