TL;DR: This is the first examination of plasma DHEA concentrations in a wild rodent and the first field experiment on the regulation of plasmaDHEA in any wild mammal, and lays the foundation for future studies on the role of D HEA in non-breeding territoriality in this species and other mammals.

TL;DR: Miniaturized heart rate telemetry shows that Uroderma bilobatum uses a novel, cyclic, bradycardic state that reduces daily energetic expenditure by 10% and counteracts heart rates as high as 900 bpm during flight.

TL;DR: A phylogenetic comparison of 91 vertebrate species shows a dichotomous pattern with respect to CBG: a dominant branch, where high levels of CBG bind most of the GC, applies to the majority of vertebrates; and a secondary branch,where low levels ofCBG bind almost none of theGC, applied to a very small subset.

TL;DR: In this article, a large-scale experiment by fertilizing two 1 km 2 stands of white spruce in the southwestern Yukon with commercial NPK fertilizer from 1987 to 1994 was conducted.

TL;DR: The data suggest that flying squirrel cortisol levels are regulated by negative feedback at a higher set point than in related species, and that high circulating cortisol levels may be required to compensate for low target tissue responsiveness in this species.
