Meeting Abstract 86.4  Thursday, Jan. 7  How pterosaurs landed and why they evolved from bipedal ancestors PADIAN, Kevin*; MAZIN, Jean-Michel; BILLON-BRUYAT, Jean-Paul; Univ. of California, Berkeley; Univ. of Lyon1, France; Canton Jura, Switzerland kpadian@berkeley.edu There is continued controversy about how pterosaurs, the flying reptiles of the Mesozoic Era, walked on land. Major bauplan changes occurred with the […]

Meeting Abstract 86.2  Thursday, Jan. 7  Can nest-site choice compensate for the effects of climate change on reptiles with temperature-dependent sex determination? REFSNIDER, Jeanine*; JANZEN, Fredric; Iowa State University; Iowa State University refsnij@iastate.edu Numerous effects of climate change on ecosystems have been demonstrated. Reptiles with temperature-dependent sex determination may be particularly threatened, as increasing temperatures could lead […]

Meeting Abstract 86.1  Thursday, Jan. 7  Adaptive divergence in green anole lizards due to species invasions HSIEH, S.T.*; SMITHERS, C.; University of Florida, Gainesville; Temple University, Philadelphia, PA; University of Florida, Gainesville sthsieh@post.harvard.edu Phenotypic plasticity is cited as a mechanism that can facilitate adaptive evolution, by enabling an immediate response to sudden environmental changes, effectively “buying time” […]

Meeting Abstract 85.3  Thursday, Jan. 7  The purple sea urchin genome suggests local adaptation along a latitudinal gradient despite high gene flow. PESPENI, M.H.*; PALUMBI, S.R.; Stanford University; Stanford University mpespeni@stanford.edu Identifying adaptive genes is a central challenge in evolutionary biology, especially when high dispersal disrupts the signal of local adaptation. Here we develop a new SNP […]

Meeting Abstract 85.1  Thursday, Jan. 7  Chlorophyll synthesis by a sea slug (Elysia chlorotica) PIERCE, S. K.*; CURTIS, N. E.; SCHWARTZ, J. A.; Univ. of South Florida; Univ. of South Florida; Univ. of South Florida pierce@cas.usf.edu The intracellular chloroplast symbiosis between the sea slug, Elysia chlorotica, and chloroplasts of the chromophytic alga, Vaucheria litorea, is supported by […]

Meeting Abstract 85.2  Thursday, Jan. 7  Acclimation of thermal sensitivity in Drosophila melanogaster from high and low latitudes COOPER, B.S.*; CZARNOłęSKI, M.; ANGILLETTA, M.J.; Indiana University; Jagiellonian University; Indiana State University brascoop@indiana.edu Organisms modify their physiological functions in response to changes in their environment, a process referred to as acclimation. Recent studies of acclimation have been influenced […]

Meeting Abstract 84.2  Thursday, Jan. 7  Shape, size and performance of a crustacean predatory appendage CLAVERIE, T.*; CHAN, E.K.; PATEK, S.N.; Univ. of Massachusetts, Amherst; Univ. of California, Berkeley; Univ. of Massachusetts, Amherst tclaverie@gmail.com While variation in size can be intuitively linked to performance, the role of shape in the development and evolutionary radiations of predatory structures […]

Meeting Abstract 84.1  Thursday, Jan. 7  Claw force and cuticle strength: Functional morphology of fiddler crab combat ANDERSON, Stuart/P*; GEORGE, Matthew; SWANSON, Brook/O; Gonzaga University; Gonzaga University; Gonzaga University sanderson@gonzaga.edu Crabs in the genus Uca are sexually dimorphic, with males displaying extreme claw asymmetry in all species. It is thought that this extreme claw asymmetry is due […]
