Meeting Abstract 16.2  Friday, Jan. 4  20-hydroxyecdysone (20E) Signaling Delay in Starvation Resistant Drosophila REYNOLDS, L. A.*; GIBBS, A. G.; University of Nevada, Las Vegas; University of Nevada, Las Vegas reyno172@unlv.nevada.edu We selected for adult starvation resistance in replicated outbred populations of Drosophila melanogaster. These populations accumulate greater lipid stores as larvae that they then use to […]

Meeting Abstract 16.4  Saturday, Jan. 4 11:00  Spatial and temporal variation in phenotypic selection in the lizard Anolis sagrei WARNER, D.A.*; HARRISON, A.; REEDY, A.; University of Alabama at Birmingham; Harvard University; University of Virginia dawarner@uab.edu Populations often experience substantial spatial and temporal variation in environmental and demographic features. This variation can impact the strength and form […]

Meeting Abstract 16.3  Saturday, Jan. 4 10:45  Mechanisms of niche divergence in an Atlantic Forest lizard group STRANGAS, M.L.*; RECODER, R.S.; RODRIGUES, M.T.; CARNAVAL, A.C.; City University of New York; Universidade de Sao Paulo; Universidade de Sao Paulo; City University of New York mariastrangas@gmail.com Determining the mechanisms that drive niche divergence in closely related taxa has the […]

Meeting Abstract 16.6  Saturday, Jan. 4 11:45  Local Adaptation of Trait Integration: Predicting the Evolutionary Trajectories of Complex Phenotypes GARCIA, M.J.*; EARLEY, R.L.; Univ. of Alabama; Univ. of Alabama mjgarcia@crimson.ua.edu An individual’s phenotype results from the interactions of many highly “integrated” traits. A fundamental goal in evolutionary studies is to understand the mechanisms that generate/maintain such connections, […]

Meeting Abstract 16.2  Saturday, Jan. 4 10:30  Genetic diversification in Rotifera: Successful Dispersal and Colonization or Local Adaptation WALSH, E.J.*; REYES, D.E.; HAMDAN, L.; RAMOS CHAVEZ, J.; KORDBACHEH, A.; Univ. of Texas at El Paso ewalsh@utep.edu Advances in molecular systematics have uncovered cryptic species in a wide variety of aquatic microinvertebrates. Here we examine genetic diversification of […]

Meeting Abstract 16.1  Saturday, Jan. 4 10:15  Do clines in Drosophila flight morphology result from adaptive environment-phenotype matching? RUSSEY, WA*; FRANKINO, WA; Univ. of Houston; Univ. of Houston warussey@gmail.com Drosophila exhibit convergent genetically-based clines and phenotypic plasticity in absolute and relative wing size; relative to warm environments, cooler environments produce large flies with disproportionately large wings. Although […]

Meeting Abstract 16.5  Saturday, Jan. 4 11:15  Delineating ecological niches and their evolution from stable isotopes and museum specimens RADER, J. A.*; DILLON, M. E. ; MARTINEZ DEL RIO, C.; University of Wyoming; University of Wyoming; University of Wyoming rader@raderstudios.com The niche is a fundamental concept in ecology, but is often difficult to operationalize and quantify. We […]

Meeting Abstract 16.1  Sunday, Jan. 4 10:15  Targets of selection and potential constraints shape the evolution of the locomotor system in lizards. SCALES, JA*; BUTLER, MA; University of South Florida; University of Hawaii jscales@usf.edu Many complex phenotypes such as the locomotor system perform multiple, and sometimes conflicting functions. The evolution of traits underlying such phenotypes may therefore […]
