PACKARD, M.J.; PACKARD, G.C.; Colorado State Univ.: Cold acclimation and cutaneous resistance to freezing in hatchling painted turtles, Chrysemys picta Neonatal painted turtles overwinter in the natal nest and may be exposed to prolonged periods of ice and cold. Hatchlings survive by supercooling, a capability that depends on their ability to resist the inoculative freezing […]

BAKER, P.J.*; COSTANZO, J.P.; IVERSON, J.B.; LEE JR., R.E.; Miami University; Miami University; Earlham College; Miami University: Adaptations to terrestrial hibernation of hatchling northern map turtles (Graptemys geographica) Field observations and laboratory experiments were conducted on hatchlings of the northern map turtle (Graptemys geographica), a species that commonly overwinters within the natal nest in the […]

LEHMER, Erin M; Colorado State University: A Rare Incident of Hibernation in Free-Ranging Black-Tailed Prairie Dogs In the natural environment, hibernating sciurids generally remain dormant during winter and enter numerous torpor bouts from the time of first immergence in fall until emergence in spring. This is in contrast to free-ranging black-tailed prairie dogs (Cynomys ludovicianus), […]

COOKE, SJ; PHILIPP, DP; University of Illinois; Illinois Natural History Survey: Physiological Consequences of Translocation and Interstock Hybridization of a Freshwater Teleost Fish The cardiovascular response to exhaustive exercise among differentiated stocks of largemouth bass was compared at 10°C and 20°C as an assessment of local adaptation and interstock hybridization. Cardiac parameters (both resting and […]

NUSSEAR, K.E.*; TRACY, C.R.; University of Nevada, Reno; University of Nevada, Reno: Influence of animal absorptance on the thermal biology of desert tortoises Individual desert tortoises have markedly different shell coloration and pigmentation. Those differences can affect the animal�s absorptance to solar radiation across the entire solar spectrum (i.e. the UV, Visible, and near Infrared). […]
