Meeting Abstract 103-6  Saturday, Jan. 7 14:45 – 15:00  The gut yeast microbiota determines insect recovery from chill coma JIMÉNEZ PADILLA , Y; LACHANCE, M-A; SINCLAIR, BJ*; Western University, London, ON, Canada bsincla7@uwo.ca http://publish.uwo.ca/~bsincla7/ Understanding the role of the microbiota in determining animals’ physiological phenotypes remains a grand challenge in organismal biology. Although yeasts are a key […]

Meeting Abstract 103-7  Saturday, Jan. 7 15:00 – 15:15  Performance benefits of slow migratory behavior in a predictable dynamic habitat HAYFORD, HA*; CARRINGTON, E; University of Washington; University of Washington hayford@uw.edu Behavior plays a fundamental role in regulating the thermal environment experienced by an ectothermic animal. Animal speed and spatiotemporal patterns of environmental variation determine the temporal […]

Meeting Abstract 103-1  Saturday, Jan. 7 13:30 – 13:45  AMPK Activity Increases in Response to Acute Cold Stress in the Zebra Mussel JOST, JA; Bradley University jjost@fsmail.bradley.edu Ectothermic species are affected by environmental fluctuations, and studies are needed on thermal tolerances since changes in ambient temperature affect metabolic demands. Zebra mussels are highly invasive, yet little is […]

Meeting Abstract 103-6  Saturday, Jan. 6 14:45 – 15:00  Novel Cell Adhesion Mechanisms in Sponge Tissues MITCHELL, JM*; NICHOLS, SA; University of Denver yinnismc@gmail.com A fundamental requirement for multicellularity is cell adhesion. This includes mechanisms by which cells adhere to each other, and to their secreted extracellular matrix (ECM). Two well characterized adhesion complexes in animals include: […]

Meeting Abstract 103-8  Saturday, Jan. 6 15:15 – 15:30  Gene expression in appendages of Centruroides sculpturatus clarify the evolutionary origin of the scorpion pectine SANTIBANEZ-LOPEZ, CE*; NOLAN, ED; SETTON, EVW; SHARMA, PP; Univ. Wisconsin-Madison; Univ. Wisconsin-Madison; Univ. Wisconsin-Madison; Univ. Wisconsin-Madison santibanezlo@wisc.edu The versatility of the articulated appendages of arthropods has contributed to their evolutionary success, granting them […]

Meeting Abstract 103-4  Saturday, Jan. 6 14:15 – 14:30  Function of BMP signaling in the annelid Capitella teleta and implication for nervous system evolution CORBET, M; JOYCE, C; SUR, A; RENFRO, A; MEYER, NP*; Clark University nmeyer@clarku.edu A key question concerning animal evolution is how centralized nervous systems (CNSs) evolved and contributed to organismal diversity. In many […]

Meeting Abstract 103-3  Saturday, Jan. 6 14:00 – 14:15  From Genes to Fossils: Investigating the Evolution of Axial Patterning in Tetrapods through Deep Time BÖHMER, C; Muséum National d’Histoire Naturelle Paris boehmer@vertevo.de Major evolutionary events in vertebrate evolution were accompanied by substantial changes in the axial skeleton including modifications in the Hox genes. These genes are critical […]

Meeting Abstract 103-2  Saturday, Jan. 6 13:45 – 14:00  Exploring adaptive and novel traits of bat faces through morphometrics and developmental genetics CAMACHO, J*; TABIN, CJ; ABZHANOV, A; Harvard University; Harvard Medical School; Imperial College London jcamacho@fas.harvard.edu https://scholar.harvard.edu/jasminc The New World leaf-nosed bats (phyllostomids) display exemplary morphological adaptations associated with specialized modes of feeding. Phyllostomid bat skulls […]

Meeting Abstract 103-1  Saturday, Jan. 6 13:30 – 13:45  Early Eye Development in the Squid Doryteuthis pealeii and the Evolution of Morphogenesis KOENIG, KM; Harvard University kmkoenig@fas.harvard.edu Classically, the cephalopod eye is known for its morphological similarity to the vertebrate single-chambered eye. However, this complexity is independently evolved. While vertebrate and fly eye and organ formation have […]
