Meeting Abstract 91-2  Wednesday, Jan. 6 10:30  Illuminating the Toll-like receptor pathways in hemichordates TASSIA, MG*; HALANYCH, KM; Auburn University; Auburn University mgt0007@auburn.edu Most invertebrates must rely solely on their innate immune system to defend against pathogenic microbes. Unlike the immunoglobulins of vertebrate adaptive immunity, innate immune receptors do not recombine to diversify their ligand specificity – […]

Meeting Abstract 91-6  Wednesday, Jan. 6 11:30  Genomic analysis of hybrid vigor in the Pacific oyster: genetic distance and ribosomal protein stoichiometry MEYER, E*; KIRK, NL; Oregon State University eli.meyer@science.oregonstate.edu Hybrid vigor has important consequences for fitness in natural populations and production in crop species, but its functional basis remains poorly understood. We used genome-wide SNP genotyping […]

L.; WEIGEL, E.G.*; WERREN, J.W.; Spelman College; Spelman College; University of Rochester emilygweigel@gmail.com http://www.choosyfemale.com The inter-organismal movement of genetic material by means other than reproduction, or horizontal gene transfer (HGT), may be more common in eukaryotes than […]

Meeting Abstract 91-5  Wednesday, Jan. 6 11:15  DNA methylation is a signiture of transcriptional and evolutionary stability in stony corals DIXON, GB*; BAY, LK; MATZ, MV; Univ. of Texas, Austin alfire.sidik@gmail.com The likeness of gene regulation to a light switch— either turned on or off— is considered instructive but overly simplistic. There is however an epigenetic element […]

Meeting Abstract 91-3  Wednesday, Jan. 6 10:45  Coevolution between nuclear and mitochondrial genomes HAVIRD, J.C.*; SLOAN, D.B.; Colorado State University; Colorado State University justin.havird@colostate.edu http://jchavird.wix.com/jchavird A mitochondrial genome is retained in all eukaryotes with a functional electron transport chain. However, in order for the mitochondria to meet the energy needs of eukaryotic cells, genetic products from the […]

Meeting Abstract 90-6  Wednesday, Jan. 6 11:15  Tracheophones revisited: The three sound source syrinx GARCIA, S.M.*; KOPUCHIAN, C.; FUXJAGER, M.J.; MINDLIN, G.B.; GOLLER, F.; University of Utah; CECOAL-CONICET; Wakeforest University; FCEN-Universidad de Buenos Aires; University of Utah Sarah.Garcia@utah.edu Avian vocalizations are highly diverse, and arise from an interplay between morphology, aerodynamics and neuromuscular control. Although variation in […]

Meeting Abstract 90-7  Wednesday, Jan. 6 11:30  Sex differences in spatial memory, hippocampal volume, and oxytocin receptor density in prairie voles Microtus ochrogaster. RICE, M.A*; HOBBS, L.E.; WALLACE, K.J.; OPHIR, A.G.; Cornell University; University of Massachusetts Amherst; Cornell University; Cornell University mr868@cornell.edu Sex differences in brain and behavior are well documented in many species. Conventional thought is […]

Meeting Abstract 90-5  Wednesday, Jan. 6 11:00  Mechanisms of wing stiffening during fast swimming in a pteropod mollusc SATTERLIE, RA; University of North Carolina Wimington satterlier@uncw.edu Acceleration from slow to fast swimming in the Pteropod Mollusc Clione limacina includes two biomechanical changes in wing activities: a change in angle of attack and wing stiffening. In our search […]
