Meeting Abstract S3.7  Tuesday, Jan. 4  Pairing dynamics and the origin of species PUEBLA, Oscar*; GUICHARD, Frédéric; BERMINGHAM, Eldredge; Smithsonian Tropical Research Institute ; McGill University; Smithsonian Tropical Research Institute oscar.puebla@mail.mcgill.ca All species are the end-product of speciation, the evolution of reproductive isolation between previously interbreeding populations. In the presence of gene flow between diverging populations (in […]

Meeting Abstract S3.11  Tuesday, Jan. 4  Next-generation sequencing and population genomics: an outlook for the future of speciation studies ROCHA, Luiz A; Univ. of Texas at Austin rocha@mail.utexas.edu The genic view of speciation (GVS) states that speciation is driven by processes at the gene (not the individual) level, that genomes are not cohesive, but porous, and that […]

Meeting Abstract S3.5  Tuesday, Jan. 4  Diversification of sympatric broadcast-spawning limpets (Cellana spp.) within the Hawaiian archipelago BIRD, C E*; HOLLAND, B S; BOWEN, B W; TOONEN, R J; University of Hawai’i at Manoa cbird@hawaii.edu Speciation remains a central enigma in biology, and nowhere is this more apparent than in shallow tropical seas where biodiversity rivals or […]

Meeting Abstract S3.6  Tuesday, Jan. 4  Assortative fertilization across hybrid genotypes promotes reproductive isolation in a bimodal hybrid zone between Mytilus blue mussels MCCARTNEY, MA*; SCHMIDT, VS; Univ. of North Carolina, Wilmington; MBL, Woods Hole mccartneym@uncw.edu Support for the view that hybrid zones demonstrate speciation in progress (rather than its failure to complete) comes from comparative studies […]

Meeting Abstract S2.8  Tuesday, Jan. 4  The ontogeny and physiology of daily oral behaviors LANGENBACH, Geerling EJ*; VAN WESSEL, Tim; ACTA, Amsterdam; University of Twente, Enschede g.langenbach@acta.nl In the masticatory system, muscle activities are the main source of force. The daily jaw muscle activity is a measure for the total daily loading of the tissues involved. The […]

Meeting Abstract S2.11  Tuesday, Jan. 4  The mandibular instantaneous center of rotation in non-human primates and its relation to gape. TERHUNE, Claire E.*; IRIARTE-DIAZ, Jose; TAYLOR, Andrea B.; ROSS, Callum F.; Duke University; University of Chicago; Duke University; University of Chicago claire.terhune@duke.edu Kinematic analyses of mandibular movement in humans have demonstrated that the location of the mandibular […]

Meeting Abstract S2.7  Tuesday, Jan. 4  The development and evolution of mammalian swallowing CAMPBELL-MALONE, R*; CROMPTON, A W; THEXTON, A J; GERMAN, R Z; Johns Hopkins University; Harvard University; King’s College, London; Johns Hopkins University rzgerman@jhu.edu Suckling is a synapomorphy that characterizes mammals. It consists of two distinct behaviors: (1) sucking, a cyclic tongue-based behavior, which is […]

Meeting Abstract S2.3  Tuesday, Jan. 4  Shifts in muscle activity patterns during the evolution of feeding in gnathostomes KONOW, N*; HERREL, A; WILLIAMS, S; ROSS, CF; DE VREE, F; CROMPTON, AW; GERMAN, RZ; SANFORD, CPJ; GINTOF, C; Brown University; CNRS/MNHH; Ohio University; University of Chicago; University of Antwerp; Harvard University; Johns Hopkins University; Hofstra University; Hofstra University […]

Meeting Abstract S2.4  Tuesday, Jan. 4  Patterns of jaw-muscle recruitment evolution in mammals WILLIAMS, SH*; VINYARD, CJ; CROMPTON, AW; HYLANDER, WL; Ohio University, Athens; NEOUCOM, Rootstown; Harvard, Cambridge; Duke Univ., Durham willias7@ohio.edu The evolution and subsequent diversification of mammals is characterized by marked changes in the morphology of the masticatory apparatus, and these marked changes are presumably […]
