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 132-2  Thursday, Jan. 7 13:45  Semi-aquatic turtles use multiple gaits when moving under water MAZOUCHOVA, N.*; HSIEH, S.T.; Temple University, Philadelphia; Temple University, Philadelphia tue61612@temple.edu Water and land transitions often require gait changes specific to the environment. For example, on land, animals walk by supporting their body weight with their limbs, but when underwater, their […]

Meeting Abstract 132-6  Thursday, Jan. 7 14:45  Pressure field measurements in the study of fish-like swimming LUCAS, KN*; DABIRI, JO; LAUDER, GV; Harvard University; Stanford University; Harvard University klucas@fas.harvard.edu Pressure fields around the body provide a key avenue for fish to interact with their fluid world. Perhaps the most iconic examples are embodied by the fish’s lateral […]

Meeting Abstract 132-5  Thursday, Jan. 7 14:30  Oxygen consumption in drift feeding trout: energetic implications for habitat selection and prey choice JOHANSEN, JL*; AKANYETI, O; TAGUCHI, M; LIAO, JC; Whitney Laboratory for Marine Bioscience, University of Florida, FL 32080, USA; Whitney Laboratory for Marine Bioscience, University of Florida, FL 32080, USA; Dept. of Agricultural and Biological Engineering, […]

Meeting Abstract 132-4  Thursday, Jan. 7 14:15  Larvacean locomotion: a kinematic investigation using ROV-sampled, high-definition videos BAUMER, A.*; LEFTWICH, M.C. ; KATIJA, K. ; The George Washington University; The George Washington University; Monterey Bay Aquarium Research Institute abaumer@gwmail.gwu.edu Larvaceans, a free-swimming tunicate, are found throughout the world’s oceans. They filter their food (e.g. small plankton, detritus, particulates) […]
