KIHSLINGER, Rebecca L.; NEVITT, Gabrielle A.; Univ. of California, Davis: Examining effects of the early rearing environment on the development of phenotype in steelhead alevins. The early rearing environment plays a critical role in the development and expression of phenotype. This vital role is frequently underestimated in captive rearing or hatchery situations. Hatcheries consistently produce […]

MAXMEN, A.B.*; CUTLER, E.; GIRIBET, G.; Harvard University; Harvard University; Harvard University: Evolutionary relationships within the protostome phylum Sipuncula; A molecular analysis of ribosomal genes and histone H3 sequence data The internal phylogeny of the phylum Sipuncula is investigated by means of DNA sequence data from three nuclear markers, two ribosomal genes (18S rRNA and […]

LYNOTT, A.J.; BAKKEN, G.S.; BANTA, M.R.; Indiana State University; Indiana State University; University of Northern Colorado: Estimating the Body Temperature of Swimming Mallard Ducklings (Anas platyrhynchos) with Infrared Thermography Body core temperature (Tb) is an important physiological parameter in thermoregulatory studies, but accurate measurements in young birds can be difficult. Radiotelemetry requires time to recover […]

DAZLEY, J.S.; FARMER, C.G.; MOORE, J; CLAYTON, F.; University of Utah; University of Utah; Veterans Administration Hospital; Veterans Administration Hospital: Esophageal Structure and Function in the American alligator An appreciation of the usefulness of reptiles as model organisms to study regulatory physiology of the gastrointestinal system is increasing. In contrast to most mammals, that generally […]

AVENI-DEFORGE, K.J.; WETHEY, D.S; Univ. of South Carolina, Columbia; Univ. of South Carolina, Columbia: Emergent properties of strength of attachment in beds of mussels Individuals within a mussel aggregation resist the hydrodynamic forces of lift and drag by attaching byssal threads to the substrate on which they live and to their neighbors. This matrix of […]

OUFIERO, C.E.*; ANGILLETTA, M.J.; Indiana State Univ., Terre Haute: Embryo Energetics and Thermal Acclimation at Fluctuating Temperatures Variation in incubation temperature may cause differences in metabolic rate at the embryonic stage, which may also persist in juveniles. Previous studies of reptiles have documented effects of constant incubation temperatures on the energetics of embryos and the […]

O’REILLY, K.M.*; FORTIN, J.K.; GJELTEN, A.A.; Univ. of Portland, OR; Washington State Univ., Pullman; Univ. of Portland, OR: Elevated adrenocortical response to stress in overwintering chickadees and nuthatches at high elevation Birds living at high elevations experience more rigorous winter weather conditions than birds living at low elevations. One mechanism birds may use to cope […]
