DAHLMAN, J.M.*; MARGOT, K.; HORWITZ, J.; POSNER, M.; Ashland University; Ashland University; Univ. of California, Los Angeles; Ashland University: Chaperone function of the heat shock protein alpha crystallin in the zebrafish lens Alpha crystallin is a small heat shock protein that is expressed in the ocular lens of all vertebrates. It contributes to the refractive […]

SHAFER, T.H.*; ROER, R.D.; GAY, D.M.; ALEXANDER, M.S.; University of North Carolina at Wilmington: Changes in hyposaline tolerance during the development of blue crab embryos (Callinectes sapidus) Ovigerous blue crabs (Callinectes sapidus) are found throughout the estuaries of southeastern NC. Therefore, their externally developing embryos are exposed to a range of ambient salinities. By the […]

WEATHERLY, J.N.; University of North Dakota: Changes in Rats’ Behavior as a Function of Upcoming Food Substance: Paradoxical Results Research has shown that rats will decrease their consumption of a substance low in hedonic value when they will soon have the opportunity to consume a highly valued substance. Other research has shown that rats will […]

LIGHT, D.B.; CAMPION, B.K.; Ripon College; Ripon College: Cell Volume Regulation by Hyla chrysoscelis Erythrocytes Hyla chrysoscelis (Cope�s gray treefrog) is a freeze-tolerant anuran. The process of freezing and thawing of extracellular fluid generates an osmotic imbalance with intracellular fluid compartments. Accordingly, we examined regulated volume decrease (RVD) by erythrocytes of this species. Cell volume […]

ERDMANN, C.G.; CAIN, S.D.; Friday Harbor Labs, Univ. of Washington; Friday Harbor Labs, Univ. of Washington: C-Fos-like immunoreactivity in the nervous system of the nudibranch mollusc Tritonia diomedea In the sea slug Tritonia diomedea, the morphology and accessibility of the brain has allowed researchers to use sharp electrodes to record intracellularly from as many as […]

PEREYRA, M.E.*; MORTON, M.L.; HAHN, T.P.; U.C. Davis; U.C. Davis; U.C. Davis: Behavioral Indicators of Photorefractoriness in Free-living Dusky Flycatchers Traditionally, spontaneous gonadal regression under stimulatory day lengths has been used to indicate the onset of photorefractoriness, particularly in captive birds. Under natural conditions, the loss of photosensitivity and onset of photorefractoriness are more difficult […]

HOFFMAN, G.G.*; ELLINGTON, W.R.; Florida State Univ.; Florida State Univ.: Bacterial expression of a functional, octameric mitochondrial creatine kinase from a polychaete. Creatine kinase (CK), which catalyzes the reversible phosphorylation of creatine, is widely distributed in lophotrochozoan protostomes and deuterostomes. Multiple gene duplication events have led to the production of isoforms which may be expressed […]

ROBINSON, N.M.*; WALTERS, L.J.; Univ. of Central Florida, Orlando: Asexual reproduction via fragmentation in the bryozoan Zoobotryon verticillatum The spaghetti bryozoan Zoobotryon verticillatum (Gymnolaemata) is found in warm water marine environments worldwide. In Mosquito Lagoon (northernmost section of the Indian River Lagoon system), the abundance of drift and attached Z. verticillatum varied greatly throughout the […]

FARRELL, W.J.*; HAYES, K.A.; WILCZYNSKI, W.; The University of Texas at Austin: Arginine Vasotocin Alters Mirror-Elicited Aggressive Behavior in Green Anolis Lizards (Anolis carolinensis). The neuropeptide arginine vasopressin and its non-mammalian homologue, arginine vasotocin (AVT) have been implicated in the regulation of a variety of species-typical social behaviors including male aggression. Prior reports suggest that […]
