Sex differences in the thermoregulation and evaporative water loss of a heterothermic bat, Lasiurus cinereus, during its spring migration Sex differences in the thermoregulation and evaporative water loss of a heterothermic bat, Lasiurus cinereus, during its spring migration
This study quantifies sex differences in thermoregulation and water loss of a small (20-35 g) insectivorous heterothermic mammal, the hoary bat Lasiurus cinereus, during its spring migration. We measured body temperature, metabolic rate and evaporative water loss, and calculated wet thermal conductance, for bats exposed to air temperatures ranging from 0 to 40°C for periods of 2-5 h...

Roosting habits of four bat species in the Black Hills of South Dakota Roosting habits of four bat species in the Black Hills of South Dakota
The availability of suitable roosts influences the distribution and abundance of bats. Quantifying roosting requirements is a necessary step toward effectively monitoring, managing, and conserving bats. Our objectives were to locate and characterize the natural, daytime summer roosts of Myotis septentrionalis, M. thysanodes, M. volans, and Eptesicus fuscus in the Black Hills of South...

The bats of Wyoming The bats of Wyoming
We examined 1280 bats of 12 species submitted to the Wyoming State Veterinary Laboratory (WSVL) for rabies testing between 1981 and 1992. The most abundant species in the sample was Myotis lucifugus, followed by Eptesicus fuscus, Lasionycteris noetivagans, M. ciliolabrum, and M. volans. Using the WSVL sample and additional museum specimens, we summarized available records and knowledge...

Effect of elevation on distribution of female bats in the Black Hills, South Dakota Effect of elevation on distribution of female bats in the Black Hills, South Dakota
Presumably, reproductive female bats are more constrained by thermoregulatory and energy needs than are males and nonreproductive females. Constraints imposed on reproductive females may limit their geographic distribution relative to other bats. Such constraints likely increase with latitude and elevation. Males of 11 bat species that inhabit the Black Hills were captured more...
