Meeting Abstract 66.5 Jan. 7 Intestinal hydrolase activity of the Burmese python, Python molurus COX, C.L.*; SECOR, S.M.; University of Alabama; University of Alabama clcox@bama.ua.edu For the Burmese pythons, the dramatic postprandial upregulation of intestinal nutrient uptake is predictably matched with concurrent upregulation of intestinal hydrolase activity. Therefore we measured from the Burmese python the postprandial response […]

Implications of meal type effects on specific dynamic action for optimal foraging
Meeting Abstract 66.3 Jan. 7 Implications of meal type effects on specific dynamic action for optimal foraging OTT, Brian D.*; SECOR, Stephen M.; The University of Alabama; The University of Alabama brian.d.ott@ua.edu Specific dynamic action (SDA), the cost of meal digestion and assimilation, is proposed to be a large component of the energy budget of amphibians and […]
Implications of brooding python postural changes on embryonic gas exchange and water loss
Meeting Abstract 66.6 Jan. 7 Implications of brooding python postural changes on embryonic gas exchange and water loss STAHLSCHMIDT, Z.R.**; DENARDO, D.F.; HOFFMAN, T.C.M.; Arizona State University; Arizona State University; Arizona State University zs@asu.edu Female pythons typically coil tightly around their eggs throughout the incubation period (40-80 days). While this behavior has been shown to provide thermal […]
Gila monster digestion and exendin-4 absence of exendin-4 effect on metabolism, intestinal performance, or plasma nutrient concentrations
Meeting Abstract 66.4 Jan. 7 Gila monster digestion and exendin-4: absence of exendin-4 effect on metabolism, intestinal performance, or plasma nutrient concentrations CHRISTEL, Carolyn M.*; DENARDO, Dale F.; SECOR, Stephen M.; Arizona State University; Arizona State University; University of Alabama carolyn.christel@asu.edu Gila monsters, one of two venomous lizard species, actively forage in their desert environment for eggs […]
Voluntary exercise and aerobic performance in several small mammals
Meeting Abstract 65.8 Jan. 7 Voluntary exercise and aerobic performance in several small mammals CHAPPELL, MA; Univ. of California, Riverside mark.chappell@ucr.edu The upper limit of sustainable metabolic power output is set by maximum oxygen consumption (VO2max). Physiologists have considerable data on VO2max from a variety of species, but little is known about how frequently animals approach VO2max […]
Unidirectional flow in the lungs of archosaurs
Meeting Abstract 65.1 Jan. 7 Unidirectional flow in the lungs of archosaurs FARMER, CG; Utah Artificial Heart Institute farmer@biology.utah.edu “A satisfactory answer has not been found to the question of the benefit of unidirectional air flow in bird lungs” (Meyer et al., 1981). Studies on pulmonary air flow of the sister group to birds, crocodilians, may provide […]

Gas exchange patterns in beetles from Southwestern USA
Meeting Abstract 65.3 Jan. 7 Gas exchange patterns in beetles from Southwestern USA KAISER, A.*; QUINLAN, M. C.; Midwestern University, Glendale, AZ; Midwestern University, Glendale, AZ akaise@midwestern.edu The unique CO2 release pattern of discontinuous gas exchange (DGE) in insects is often assumed to have evolved to conserve body water. Recently, several alternative hypotheses have been presented to […]
Effects of Experimental Erythropoietin Elevation on Voluntary Exercise and Maximal Aerobic Capacity in House Mice
