Meeting Abstract S6-2.3  Jan. 5  Measuring the costs & benefits of receiving sperm in Drosophila melanogaster RICE, William/R*; STEWART, Andrew/D; MORROW, Edward/H; KUIJPER, Braum; Univ. of California; Univ. of California; Uppsala University; Uppsala University rice@lifesci.ucsb.edu Female D. melanogaster commonly mate again (remate) before they have used all sperm form a prior mating. We evaluated the costs and […]

Meeting Abstract S6-2.1  Jan. 5  Functions of seminal proteins in reproductive interactions between the sexes in Drosophila WOLFNER, M.F.*; RAVI RAM, K.; MUELLER, J.M.; WONG, A.; MCGRAW, L.A.; ALBRIGHT, S.N.; SIROT, L.K.; PAGE, J.L.; Cornell University; Cornell University; Cornell University; Cornell University; Cornell University; Cornell University; Cornell University; Cornell University mfw5@cornell.edu The seminal proteins that females receive […]

Meeting Abstract S6-2.4  Jan. 5  Complex male X female interactions and the evolution of ejaculate characterstics PITNICK, Scott*; BJORK, Adam; PATTARINI, James; Syracuse University; Syracuse University; Syracuse University sspitnic@syr.edu Ejaculate-female interactions are poorly understood but are expected to be widespread, complex and to have important implications for differential male fertilization success, the evolution of polyandry and diversification […]

Meeting Abstract S6-2.2  Jan. 5  Adaptive Evolution and Coevolution of Sperm – Egg Recognition Molecules SWANSON, WJ*; AAGAARD, J; CLARK, N; University of Washington wswanson@gs.washington.edu The molecular basis of speciation remains one of the outstanding questions in evolutionary biology. Recent studies have indicated that the rapid evolution of reproductive proteins may be involved in reproductive isolation and […]

Meeting Abstract S6-2.3  Saturday, Jan. 5  Social Regulation of the Brain FERNALD, R.D.; Stanford University How does behavior change the brain? The long term objective our research program is to understand how social interactions produce specific changes in the brain. While it is common to study how the brain controls behavior, learning how the brain is influenced […]

Meeting Abstract S6-2.2  Saturday, Jan. 5  Musk Shrews: A Novel Model for Eating Disorders SCHNEIDER, Johanna S.; University of Virginia johanna.schneider@virginia.edu Concurrent with the rise in obesity has been the identification of binge eating disorder (BED). This disorder is characterized by repeated, intermittent overconsumption of food, but is distinguishable from bulimia in that food intake is not […]

Meeting Abstract S6-2.1  Saturday, Jan. 5  GnRH II A Multipurpose Peptide RISSMAN, Emilie F.; University of Virginia rissman@virginia.edu We have pioneered the use of the musk shrew (Suncus murinus) for studies of reproductive behavior. One of our novel findings is that this primitive placental mammal has at least two forms of gonadotropin releasing hormone (GnRH) in brain. […]

Meeting Abstract S6-2.4  Saturday, Jan. 5  Behavioral and physiological consequences of an audience in the group living cichlid, Astatotilapia burtoni DESJARDINS, J.K.; FERNALD, R.D.; Stanford University; Stanford University In social animals, communication rarely involves only two animals. Rather individuals or groups of animals form an audience within range of the signaler and the receiver. Audience members can […]
