Meeting Abstract 101.2  Thursday, Jan. 7  Immunohistochemical and Histological Analyses Indicating the Presence of SCP-like Neuropeptides in Larval Crassostrea virginica (Bivalvia) ELLIS, IE*; KEMPF, SC; Auburn University; Auburn University ellisir@auburn.edu The Eastern oyster Crassostrea virginica is an important species within both estuarine ecosystems and the aquaculture industry. Investigating how the larval nervous system affects larval behaviors, such […]

Meeting Abstract 101.6  Thursday, Jan. 7  Effects of temperature on the motor control of chameleon feeding ANDERSON, C.V.*; DEBAN, S.M.; University of South Florida cvanders@mail.usf.edu Environmental temperature effects muscle contractile velocity and thus constrains the activity patterns of ectotherms. As temperature decreases, performance of muscle-powered movements such as locomotion and tongue protraction decline and hinder prey capture […]

Meeting Abstract 101.3  Thursday, Jan. 7  Discrete odor sampling of the Oregon shore crab Hemigrapsus oregonensis during ontogeny WALDROP, LD; Univ. of California, Berkeley lwaldrop@berkeley.edu Crabs, like many malacostracan crustaceans, sense chemical signals in their fluid surroundings using chemosensory hair arrays on antennules to discretely sample odor-laden fluid (sniffing). Sniffing occurs when a quick downstroke of the […]

Meeting Abstract 100.5  Thursday, Jan. 7  Mapping the Epigenetic Landscape: Rediscovering Waddington in the Post-Genomic Age JAMNICZKY, H.A.*; BOUGHNER, J.C.; GONZALEZ, P.N.; PARSONS, T.E.; POWELL, C.D.; ROLIAN, C.; SCHMIDT, E.J.; BOOKSTEIN, F.L.; HALLGRIMSSON, B.; Univ. of Calgary, Canada; Univ. of Calgary, Canada; Univ. Nacional de La Plata, Argentina; Univ. of Calgary, Canada; Univ. of Calgary, Canada; Univ. […]

Meeting Abstract 100.4  Thursday, Jan. 7  Integration of squirrel mandibles ZELDITCH, M.L.*; SWIDERSKI, D.L.; Univ of Michigan, Ann Arbor; Univ of Michigan, Ann Arbor zelditch@umich.edu Understanding how developmental modules are assembled into functionally integrated morphologies is central to our understanding of biological organization. Morphological integration, a key part of that organization, coordinates variation among parts, maintaining relationships […]

Meeting Abstract 100.3  Thursday, Jan. 7  Evolutionary reorganization of moth wing patterns towards a ‘dead leaf’ resemblance SUZUKI, Takao*; KURATANI, Shigeru; RIKEN CDB, Japan; RIKEN CDB, Japan tsuzuki@cdb.riken.jp How an enormous organismal diversity and complexity could have evolved is a fundamental question of design principles of living organisms. As seen in vertebrate head skeleton evolution, the diversity […]

Meeting Abstract 100.2  Thursday, Jan. 7  Evolutionary lability of integration in Cambrian ptychoparioid trilobites WEBSTER, M.*; ZELDITCH, M.L.; Univ. Chicago; Univ. Michigan mwebster@geosci.uchicago.edu Phenotypic integration can constrain evolution by channeling variation into few dimensions: lineages characterized by strong and invariant integration structures should have little capacity to generate morphological novelty, especially if integration arises through direct interactions […]

Meeting Abstract 100.1  Thursday, Jan. 7  Darwin’s Avicularia: How an Early Sense of Modularity Links Vestigiality, Functional Innovation and the Evolution of Polymorphism CARTER, M.C.; LIDGARD, S.*; GORDON, D.P.; GARDNER, J.P.A.; Victoria University of Wellington, New Zealand; Field Museum, Chicago ; National Institute of Water and Atmospheric Research, Wellington, New Zealand ; Victoria University of Wellington, New […]

Meeting Abstract 99.4  Thursday, Jan. 7  Towards the mechanistic basis of digit identity frame shift in birds WAGNER, G. P. *; YOUNG-BRIM, R. ; Yale University; Yale University gunter.wagner@yale.edu One of the most enduring conflicts in homology assessment is the evidence concerning the identity of anvian digits in the wing. Anatomical and paleontological evidence shows that the […]

Meeting Abstract 99.5  Thursday, Jan. 7  Posterior HoxA and HoxD Genes in Avian Limb Development FOWLER, D.A.**; DE BAKKER, M.A.G.; RICHARDSON, M.K.; Institute of Biology Leiden (IBL), Leiden University; Institute of Biology Leiden (IBL), Leiden University; Institute of Biology Leiden (IBL), Leiden University d.a.fowler.2@umail.leidenuniv.nl Comparative studies of regulatory networks and their constituent signaling factors provide a powerful […]
