Meeting Abstract 125-4  Sunday, Jan. 7 11:00 – 11:15  Disparate patterns of thermal adaptation between life stages in temperate vs. tropical Drosophila melanogaster LOCKWOOD, BL*; GUPTA, T; SCAVOTTO, R; University of Vermont; University of Vermont; University of Vermont Brent.Lockwood@uvm.edu http://www.uvm.edu/~bllockwo/ Many terrestrial ectothermic species exhibit limited variation in upper thermal tolerance across latitude. However, these trends may […]

Meeting Abstract 125-5  Sunday, Jan. 7 11:15 – 11:30  Cavefish Metabolic Adaptation: Hungry, Fat, and Healthy ROHNER, N; Stowers Institute for Medical Research nro@stowers.org Understanding the genetic basis of adaptation has broad implications not only for a basic understanding of evolution, but also for human pathologies given that many human diseases are a consequence of mis-adaptation to […]

Meeting Abstract 124-6  Sunday, Jan. 7 11:30 – 11:45  On the Hydrodynamics of Anomalocaris Tail Fins SHEPPARD, KA*; CARON, JB; RIVAL, DE; Queen’s University; University of Toronto; Queen’s University k.sheppard@queensu.ca The arthropod Anomalocaris canadensis, described from the 508 million-year-old Burgess Shale site, is considered the apex predator of the Cambrian period with its prominent compound eyes, grasping […]

Meeting Abstract 124-5  Sunday, Jan. 7 11:15 – 11:30  New Burgess Shale polychaete reveals the origin of the annelid head NANGLU, K*; CARON, J.-B.; University of Toronto; Royal Ontario Museum karma.nanglu@mail.utoronto.ca Annelida is one of the most speciose (~17,000 species) and ecologically successful phyla. Key to this success is their flexible body plan with metameric trunk segments […]

Meeting Abstract 124-1  Sunday, Jan. 7 10:15 – 10:30  Molgulid Tales SWALLA, BJ; Univ. of Washington, Seattle bjswalla@u.washington.edu https://faculty.washington.edu/bjswalla/ Transcriptome and genome data offer an exciting new approach to examine the origin and evolution of the chordate body plan. Chordate body plan evolution can be studied with two tunicate species with radically different larval body plans that […]

Meeting Abstract 124-2  Sunday, Jan. 7 10:30 – 10:45  Elongating animal body plans: the role of Notch/delta signaling in mollusc posterior growth JOHNSON, AB; LAMBERT, JD*; Univ. of Rochester; Univ. of Rochester dlamber2@mail.rochester.edu In many animal groups the anterior develops first, and the body elongates progressively by growth at the posterior pole. This may have been present […]

Meeting Abstract 124-4  Sunday, Jan. 7 11:00 – 11:15  Comparative genomics of seep-dwelling tubeworm (Siboglinidae: Annelida) endosymbionts LI, Y*; HALANYCH, KM; Auburn University yzl0084@auburn.edu The evolution of gutless siboglinids, which are important members of chemosynthetic communities, has been hypothesized to be driven by preference for reducing habitats and their dependence on endosymbionts. However, genomes from only a […]

Meeting Abstract 124-7  Sunday, Jan. 7 11:45 – 12:00  Comparative Transcriptomics Reveals Extensive Diversity of Insulin-like Peptides in Corals DOUGAN, KE*; RODRIGUEZ-LANETTY, M; Florida International University; Florida International University katherine.e.dougan@gmail.com Insulin is an evolutionarily important hormone with diverse roles in metabolism, cellular growth, development, and longevity in metazoans. While the pleiotropic roles of the insulin pathway are […]
