WARD, C.K.*; WILLIAMS, M; MENDONCA, M.T.; Auburn University; Auburn University; Auburn University: Decreased stress in the tropics: A physiological explanation for the Jimmy Buffet effect? The stress response is a highly conserved set of physiological and behavioral mechanisms that are initiated when there is a threat to homeostasis. Recently, studies have shown that vertebrates in […]

BREVES, J.P.; SPECKER, J.L.; University of Rhode Island; University of Rhode Island: Cortisol Stress Response of Juvenile Winter Flounder (Pseudopleuronectes americanus) to Predators Depletion of wild stocks of winter flounder (Pseudopleuronectes americanus) in the Northwestern Atlantic has warranted stronger fishing regulations in the last decade. The rearing of juvenile fish in hatcheries for release in […]

BALKE, M.J.; MAGLIA, A.M.; University of Missouri- Rolla; University of Missouri- Rolla: Comparative Morphology of the Anuran Nasal Capsule The nasal capsule of frogs is a highly complex, but poorly known morphological assembly. Because the cartilages of the capsule are difficult to identify using traditional methods of dissection and/or clearing-and-staining, they are rarely described. Thus, […]

SANFORD, Christopher P.; Hofstra University, New York: Comparative Kinematic Analysis of a Novel Feeding Mechanism in Salmonid Fishes Salmonid fishes possess a novel feeding mechanism that involves structural modification of the hyoid system. This tongue-bite apparatus of salmonids consists of a set of well-developed teeth on the dorsal surface of the anterior hyoid region and […]

RENN, Suzy C.P.; AUBIN-HORTH, Nadia; ANNIS, Sarah W.; HOFMANN, Hans A; Bauer Center for Genomics Research, Harvard University: Comparative Functional Genomics and the Study of Complex Phenotypes In “Non-Model” Organisms The recent and rapid speciation of African Cichlids has produced a wealth of behavioral and morphological phenotypes with little genomic divergence and thus offers an […]

NESTLER, J.R.*; WHEELING, R.J.; BRIDGER, C.; Walla Walla College; Walla Walla College; Union College: Circadian Cycle of Activity and Metabolism in the California Sea Cucumber (Parastichopus californicus) Sea cucumbers (Holothuroidea) are important in ocean communities by affecting physical and chemical characteristics of sediment through their deposit feeding activities. We examined the daily cycle of movement, […]

KAILASANATH, V.; BURMEISTER, S.S.; HOKE, K.L.; FERNALD, R.D.; Stanford University; Stanford University; Stanford University; Stanford University: Characterization of Multiple Estrogen Receptors in a Cichlid Fish Estrogen plays a critical role in development, physiology, and behavior of both males and females through its action on estrogen receptors (ERs). In the cichlid fish, Haplochromis burtoni, social behaviors […]

CLAESON, K.*; AGNOL�N, F.L.; APESTEGU�A, S.; Univ. of Massachusetts, Amherst; Museo Argentino de Ciencias Naturales B. Rivadavia, Buenos Aires; Museo Argentino de Ciencias Naturales B. Rivadavia, Buenos Aires: Ceratodontiformes (Pisces: Dipnoi) of Argentina Freshwater vertebrate remains recovered from Patagonia include many isolated dipnoan tooth plates. These fishes were prominent during the �Lacustrine Senonian� of the […]

MCGAW, I.J.; University Of Nevada, Las Vegas: Cardiovascular Dynamics of Postprandial Dungeness Crabs, Cancer magister, During Hypoxic Exposure Decapod crustaceans react to hypoxia with a pronounced bradycardia and diversion of hemolymph to ventral structures. In contrast, when they feed there is an increase in both cardiac and respiratory variables. The question then arises, as to […]

PEARSE, J.S.*; LEONARD, J.L.; BREUGELMANS, K.; BACKELJAU, T.; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz; Royal Belgian Istitute of Natural Sciences, Brussels; Royal Belgian Istitute of Natural Sciences, Brussels: COI data reveal surprises in clades of banana slugs (Stylommatophoa: Arionidae, genus Ariolimax). Banana slugs occur along the west coast of North America, […]
