SWANSON, DL*; THOMAS, NE; University of South Dakota: Relationship of plasma triglycerides and creatine kinase to overnight temperature in winter acclimatized small birds Plasma triglyceride (TG) levels and creatine kinase (CK) activity may increase during long-distance flights in migratory birds, TG as an additional lipid fuel source and CK as a result of flight-induced muscle […]

PAITZ, Ryan*; JANZEN, Fredric; BOWDEN, Rachel; Illinois State Univ.; Iowa State Univ.; Illinois State Univ.: Relationship between plasma and egg yolk steroid levels in the painted turtle In species that undergo rapid egg formation (e.g., birds), steroid concentrations in plasma and those in yolk often closely match. In contrast, in species in which the process […]

PORE, S.A.; SILVERMAN, L.N.; SPIVAK, A.; LIGHT, D.B.**; Lake Forest College; Lake Forest College; Lake Forest College; Lake Forest College: Regulated Volume Decrease in Alligator mississippiensis Erythrocytes |We examined regulated volume decrease (RVD) in Alligator mississippiensis erythrocytes. Cell volume was measured electronically with a Coulter counter. Exposure of erythrocytes to a hypotonic (0.5X) Ringer caused […]

The physiology of temperature-dependant sex determination (TSD) has been the subject […]

PICARD, Kathryn T.*; NEWSOM, Ellen; SECOR, Stephen M.; University of Alabama; University of Alabama; University of Alabama: Postprandial response of circulating metabolites for snakes Snakes experience significant increases in metabolic rate after feeding stemming from the many activities employed to breakdown, absorb, and assimilate their large intact meals. In maintaining such high levels of metabolism […]

HELMSTETTER, C; SECOR, S.M*; POPE, R.K.; LIGNOT, J-H; Louis Pasteur University; University of Alabama; Indiana University South Bend; Louis Pasteur University: Postprandial cellular replication and morphological responses of the Burmese python gastrointestinal tract. Changes in cellular ultrastructure and replication associated with the dramatic digestive regulation of the Burmese python (Python molurus) with fasting and feeding […]

WACKER, DW*; WALKER, BG; COVERDILL, AJ; O’BRIEN, S; WINGFIELD, JC; Univ. of Washington; Univ. of Washington; Univ. of Washington; Univ. of Washington; Univ. of Washington: Plasma testosterone and aggression in breeding sooty fox sparrows, Passerella unalaschcensis The Challenge Hypothesis states that males may up-regulate plasma testosterone (T) secretion in response to socially unstable situations. This […]

WILLIAMS, J.B.*; LEE, R.E.; University of Nevada Las Vegas; Miami University: Plant senescence cues entry into diapause in the gall fly, Eurosta solidaginis: resulting metabolic depression is critical for water conservation. Mechanisms and possible cues for seasonal increases in desiccation resistance in larvae of the goldenrod gall fly, Eurosta solidaginis, were examined before and after […]

COX, N.L.*; HALANYCH, K.M.; Auburn University, Alabama: Phylogeography of Sterechinus neumayeri from South American and Antarctic waters using the 16S mtDNA marker Separation of South America and Antarctica, approximately 30 million years ago, led to the creation of the Drake Passage and the Antarctic Circumpolar Current, subjecting Antarctic benthic fauna to isolation for nearly 25 […]
