Meeting Abstract S7-1.3.1  Jan. 6  Form and Function of Identified Insect Motoneurons DUCH, Carsten; Arizona State University carsten.duch@asu.edu Understanding complex neural circuitry requires an understanding of the functions of its basic components – individual neurons. A single neuron�s dendritic tree may receive thousands of input synapses. Input integration and computation are strongly affected by synapse distributions, dendritic […]

Meeting Abstract S7-1.1.1  Jan. 6  Changing Speeds in a Central Pattern Generator SATTERLIE, Richard; University of North Carolina Wilmginton satterlier@uncw.edu Several common threads run through the fabric of central pattern generator networks, including those at the circuit level, such as reciprocal inhibition, at the cellular level, such as postinhibitory rebound, and at the molecular level, such as […]

Meeting Abstract S7-1.4.2  Jan. 6  An Inhibitory Spinal Reflex Between Elbow Flexor Synergists BARRY, BK*; ENOKA, RM; Univ. of Colorado, Boulder; Univ. of Colorado, Boulder Benjamin.Barry@colorado.edu Decades of work on spinal reflexes in humans based on measuring Hoffmann (H) reflexes in muscles of the forearm and lower leg has provided a relatively limited understanding of the modulation […]

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 S6-1.4  Jan. 5  Urbilaterian Reproduction: the evolution of metazoan germ cell specification mechanisms EXTAVOUR, Cassandra G M; University of Cambridge cgme2@hermes.cam.ac.uk A key focus of evolutionary developmental biology in recent years has been to elucidate the evolution of developmental mechanisms as a means to reconstructing hypothetical last common ancestors of various sister clades. Promiment among […]

Meeting Abstract S6-1.3  Jan. 5  Postcopulatory male-female interactions in Drosophila melanogaster: dissecting the female side. LAWNICZAK, Mara*; BEGUN, David; UCL/UCDavis; UCDavis marakat@gmail.com In Drosophila, what we know about the proteins involved in post-mating interactions is heavily biased towards the male side. Genes important in female-mediation of seminal fluid and sperm (including female effects on the outcome of […]

Meeting Abstract S6-1.6  Jan. 5  Genetics and molecular evolution of male reproductive genes CIVETTA, Alberto; University of Winnipeg a.civetta@uwinnipeg.ca It has been shown that genes with a role in reproduction evolve relatively faster than others. Most comparative genomics analyses however, have pooled a wide variety of genes into a single sex-related category and differences in rates across […]
