KAHN, P.F.**; MENDONCA, M.T.; Auburn University, Auburn, Alabama; Auburn University, Auburn, Alabama: Seasonal Changes in Sex Steroids of the Gopher Tortoise (Gopherus polyphemus) and Their Relationship to Upper Respiratory Tract Disease Anthropogenic factors have contributed substantially to the decline in threatened gopher tortoise populations. However, disease may also be a considerable threat to the survival […]

BLOMQUIST, Charles H.*; LIMA, Paul H.; ATKINSON, Shannon; University of Minnesota; University of Minnesota; Alaska SeaLife Center/University of Alaska Fairbanks: Activity of Steroidogenic Enzymes in Placenta and in Lung, Fat and Skin of the Steller Sea Lion Pup (Eumetopias jubatus) Steroidogenic enzymes that regulate levels of estrogens and androgens in mammalian tissues may be targets […]
Why do Africanized honey bees have higher metabolic capacities than Europeans
Meeting Abstract 38.5 Jan. 5 Why do Africanized honey bees have higher metabolic capacities than Europeans? GRAYSON, Dina L.*; HARRISON, Jon F.; FEWELL, Jennifer H.; Arizona State University Dina.Grayson@asu.edu Africanized honey bees (AHB, Apis mellifera scutellata) are a highly successful invasive species that has spread throughout the neotropics by out-competing, hybridizing with, and replacing existing European honey […]
Ventilation is metabolically expensive in resting and running guinea fowl
Meeting Abstract 38.3 Jan. 5 Ventilation is metabolically expensive in resting and running guinea fowl MARKLEY, J.S.*; CARRIER, D.R.; University of Utah; University of Utah markley@biology.utah.edu Avian ventilation may be metabolically costly because the mechanical work required to overcome the inertial and gravitational resistance to movement of the mass of the sternum, associated flight muscles, and viscera […]
Neutrons, Niches, and Adaptive Radiation in Cinclodes Ovenbirds
Meeting Abstract 38.2 Jan. 5 Neutrons, Niches, and Adaptive Radiation in Cinclodes Ovenbirds MARTINEZ DEL RIO, C.*; SABAT, P.; Univ. of Wyoming; Univ. de Chile cmdelrio@uwyo.edu Passerines are astoundingly speciose and ecologically diverse. However, remarkably few songbird species have evolved a marine habit. The genus Cinclodes (Furnariidae) is an exception. In addition to species that inhabit terrestrial/freshwater […]

Does body size affect the safety margin for oxygen delivery in flying dragonflies
Meeting Abstract 38.4 Jan. 5 Does body size affect the safety margin for oxygen delivery in flying dragonflies? HENRY, J.R.*; HARRISON, J.F.; Arizona State University; Arizona State University Joanna.Henry@asu.edu It has been widely hypothesized that the evolution of insect gigantism during the late Paleozoic was permitted due to increased atmospheric oxygen levels at the time. One mechanism […]

Meeting Abstract 38.2 Friday, Jan. 4 Physiological dimorphisms in pre- and post-reproductive spotted salamanders: endocrine and mitochondrial density differences FINKLER, M.S.*; WILLIAMS, M.K.; MCELVEEN, R.T.; Indiana Univ. Kokomo; Indiana Univ. Kokomo; Indiana Univ. Kokomo mfinkler@iuk.edu We investigated potential differences in circulating levels of corticosterone and thyroxine and in mitochondrial densities in various tissues of male and female […]
PERIRECEPTOR ROLE FOR THE HARDERIAN GLAND IN PHEROMONE DETECTION IN GARTER SNAKES
Meeting Abstract 38.4 Friday, Jan. 4 PERIRECEPTOR ROLE FOR THE HARDERIAN GLAND IN PHEROMONE DETECTION IN GARTER SNAKES MASON, R.T.*; HALPERN, M.; Oregon State University; SUNY Health Science Center at Brooklyn masonr@science.oregonstate.edu One of the few vertebrate pheromones that has been isolated, purified, and characterized is the sex pheromone of the red-sided garter snake (Thamnophis sirtalis parietalis).
