Postprandial changes in cardio-respiratory responses of the Savannah monitor (Varanus exanthematicus

CROSSLEY, D. A.*; HICKS, J. W.; BENNETT, A.F.: Postprandial changes in cardio-respiratory responses of the Savannah monitor (Varanus exanthematicus Cardio-respiratory control has been well characterized in numerous endothermic vertebrates, however our understanding of these systems in ectothermic vertebrates remains poorly understood. The purpose of this study was to thoroughly assess the cardiovascular and pulmonary responses […]

How does the respiratory response to hypoxia change throughout ontogeny in a grasshopper and a caterpillar

GREENLEE, K.J.*; HARRISON, J.F.; EGBERT, K. : How does the respiratory response to hypoxia change throughout ontogeny in a grasshopper and a caterpillar? As insects age, body size can increase dramatically. For example, grasshoppers (Schistocerca americana) grow to 100 times their original mass, and larval tobacco hornworms (Manduca sexta) increase an impressive 7,000-fold from hatchling […]

Hovering performance of hummingbirds in hyperoxic gas mixtures

Altshuler, D.L.*; Chai, Peng: Hovering performance of hummingbirds in hyperoxic gas mixtures We present a test of the hypothesis that inspiration of hyperoxic air increases hummingbird hovering performance when birds are challenged aerodynamically. We measured the maximum duration of hovering flight and the simultaneous oxygen consumption of ruby-throated hummingbirds (Archilochus colubris) in low density heliox […]

Variation in growth of Brown-Headed Cowbird nestlings and energetic impacts on their host parents

KILPATRICK, A.M.: Variation in growth of Brown-Headed Cowbird nestlings and energetic impacts on their host parents. I tested several hypotheses about the plasticity of avian growth by comparing growth of Brown-Headed Cowbird (Molothrus ater) nestlings in twenty different host species. Cowbird growth was positively correlated with site latitude (which negatively co-varied with maximum temperature) and […]
