GALIMA, M.M.*; LOWE, C.; KELLEY, K.M.; California State University Long Beach; California State University Long Beach; California State University Long Beach: Endocrine and physiological impacts of fishing (line-catching) and confinement on the marine teleost, California sheephead (Semicossyphus pulcher) The impact of line-catching and confinement on the physiological stress response in the California sheephead (Semicossyphus pulcher) […]

WALKER, B.G.*; WINGFIELD, J.C.; BOERSMA, P.D.; Univ. of Washington, Seattle; Univ. of Washington, Seattle; Univ. of Washington, Seattle: Developmental and nutritional aspects of the adrenocortical stress response in free-living Magellanic penguin chicks In nest-bound chicks that are unable to defend themselves or avoid noxious stimuli, a robust adrenocortical stress response shortly after hatching may be […]

YAO, M*; WESTPHAL, N; DENVER, RJ; Univ. of Michigan; Univ. of Michigan; Univ. of Michigan: Acute stress-induced elevation in corticotropin-releasing hormone expression in Xenopus laevis. Corticotropin releasing hormone (CRH) plays a central role in the regulation of neuroendocrine, autonomic, and behavioral responses to physical and emotional stress. In nonmammalian vertebrates, CRH may regulate both the […]

BRAINERD, E.L.*; HOOGENDYK, T.A.; MOOMAW, H.A.; TOWNSEND, P.J.; University of Massachusetts, Amherst: Yawning, breathing and stretching in humans and other vertebrates We have collected video of yawn-like behaviors in cartilaginous and ray-finned fishes, a lungfish, salamanders, caecilians, mammals, turtles, lizards, an alligator and birds. All share a similar jaw movement pattern during yawning: a slow […]

RUBEGA, M.A. *; RAY, M.K. *; University of Connecticut: Surface tension transport in red phalaropes Phalaropus fulicarius; an examination of interspecific variation in a common feeding mechanism. Surface tension transport (STT), an avian feeding mechanism which uses the surface tension of the water adhering to prey to transport it along a bird’s beak and into […]

BORRELL, Brendan J.; Univ. of California, Berkeley: Suction Feeding in the Orchid Bees Energy flux during nectar feeding is optimal at an intermediate nectar sugar concentration, which depends on the morphology of the feeding apparatus and the modality of fluid feeding. Biophysical models predict that a shift from capillary-based lapping to suction feeding will lead […]

PATEK, S.N.*; KORFF, W.; CALDWELL, R.; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley: Springy saddles: a new model of energy storage in the mantis shrimp�s strike Mantis shrimp (Stomatopoda) have specialized feeding appendages which are used for smashing shells or spearing fish. We measured the speed and forces generated by […]

YANEGA, GREGOR; RUBEGA, MARGARET; University of Connecticut: Placing intramandibular kinesis in hummingbirds in the context of tetrapod feeding evolution During previous studies with ruby-throated hummingbirds (Archilochus colubris), we discovered a novel mode of intramandibular flexion in birds attempting to catch fruit flies. We document this mode of kinesis in two additional hummingbird species, magnificent hummingbird […]

WILLIAMS, S.H.; VINYARD, C.J.; WALL, C.E.; HYLANDER, W.L.; Duke University, Durham; Duke University, Durham; Duke University, Durham; Duke University, Durham: Masticatory strains in the mandibular corpus of selenodont artiodactyls Although selenodont artiodactyls have been the subject of several theoretical studies of masticatory biomechanics, very little is known about in vivo loading regimes in the mandible […]

RAMSAY , Jason B; WILGA, Cheryl D; University of Rhode Island; University of Rhode Island: Dual Function Shark Teeth Whitespotted bamboo sharks, Chiloscyllium plagiosum, readily feed on hard and soft prey. However, C. plagiosum does not possess dental morphology that is typically associated with prey crushing. Instead, they possess broad faced, cusped teeth commonly associated […]
