SIEG, Annette*; O’CONNOR, Michael; Drexel University; Drexel University: Exploring the Possible Radiative Origins of Interspecific Metabolic Allometries The correlation between body size and a large suite of organismal characteristics has been a subject of much interest in the biological community; and, recently, the scaling of metabolic rate with body size has received renewed attention. The […]

HUGHES, Bradley/S. *; CULLUM, Alistair/J.; BENNETT, Albert/F.; University of California, Irvine; Creighton University; University of California, Irvine: Experimental Evolutionary Adaptation to Environmental pH in the bacterium Abstract�The evolutionary responses of organisms to changes in abiotic environmental factors�such as temperature and pH�have been of longstanding interest, because they are naturally variable and can sometimes reach stressful […]

HAYASHI, C.Y.*; SWANSON, B.O.; BLACKLEDGE, T.A.; SUMMERS, A.P.; Univ. of California, Riverside; Pacific University, Oregon; Univ. of Akron, Ohio; Univ. of California, Irvine: Evolution of the Material Properties of Spider Dragline Silk The evolution of biological materials is poorly understood, but is critical for understanding biodiversity. For example, the performance, and hence evolution of spiders […]

WIERSMA, P.*; MUNOZ-GARCIA, A.; WILLIAMS, J.B.; Ohio State Univ.; Ohio State Univ.; Ohio State Univ.: Do basal metabolic rates of tropical birds suggest a low pace of life? The effects of extrinsic factors on life-history trade-offs may result in a slow to fast �pace of life� continuum. Tropical and temperate climates are supposed to generate […]

Meeting Abstract 76.3  Sunday, Jan. 6  Unsteady computational fluid dynamics computation of fish suction feeding on stationary prey SKORCZEWSKI, T.L.*; CHEER, A.Y.; WAINWRIGHT, P.C.; CHEUNG, S.H.; University of California, Davis; University of California, Davis; University of California, Davis; University of California, Davis tskorc@math.ucdavis.edu During a suction feeding event, a fish rapidly expands its buccal cavity, thus creating […]

Meeting Abstract 76.5  Sunday, Jan. 6  Morphology of a picky eater: A novel mechanism underlying premaxillary protrusion and retraction within Poeciliidae HERNANDEZ, L.P.*; FERRY-GRAHAM, L.; GIBB, A.C.; George Washington University; Moss Landing Marine Labs; Northern Arizona University phernand@gwu.edu Upper jaw protrusion is hypothesized to improve feeding performance in teleost fishes by enhancing suction production and the stealth […]

Meeting Abstract 76.4  Sunday, Jan. 6  Jaw protrusion increases the hydrodynamic forces suction feeding fishes exert on their prey HOLZMAN, R*; DAY, SW; MEHTA, RS; WAINWRIGHT, PC; Univ. of California, Davis; Rochester Inst. of Technology; Univ. of California, Davis; Univ. of California, Davis raholzman@ucdavis.edu Jaw protrusion is a major innovation found in several groups of modern fishes.

Meeting Abstract 76.1  Sunday, Jan. 6  Hyoid system in specialized and generalized gasterosteiforms LEYSEN, H.*; ADRIAENS, D.; Ghent University, Belgium; Ghent University, Belgium heleen.leysen@ugent.be The family of Syngnathidae (Gasterosteiformes) encompasses the pipefishes and seahorses. Apart from the prehensile seahorse tail and the elongated pipefish body, syngnathids are characterized by a remarkable cranial morphology with an elongated snout. […]

Meeting Abstract 76.2  Sunday, Jan. 6  Evolution of prey capture kinematics in centrarchid fishes WAINWRIGHT, P.C.**; MEHTA, R.S.; TRAN, H.Q.; ODUFALU, F.; Univ. of California, Davis pcwainwright@ucdavis.edu How are prey capture kinematics modified during the evolutionary diversification of suction feeding fishes? Little is known about this process, and yet modifications to kinematics may accompany trophic specialization and […]
