Effects of capture on stress-axis measures in endangered little brown bats (<i>Myotis lucifugus</i>)
No full textLittle brown bats (Myotis lucifugus) are a widely distributed species in North America that have been decimated
by the fungal disease white-nose syndrome. As such, little brown bats are the focus of monitoring and research
initiatives that often include capturing and handling free-ranging individuals. We examined the stress response of
198 adult female little brown bats after being captured from three bat houses, during the summer. Our objective
was to inform best practices to researchers capturing and handling bats in the wild. We compared the stress
response among bats held for 30 min, and then among bats held alone or in
a group with conspecifics. We measured the levels of plasma total and free cortisol, maximum corticosteroid
binding capacity (MCBC), and blood glucose. Relative to baseline, total and free cortisol levels were significantly
higher in bats held for 15–30 min and higher still in those held for > 30 min. Blood glucose levels were elevated
after >30 min of holding. MCBC levels showed no differences among holding times. We detected a weak effect
of social holding condition, with solitary-held bats having lower total cortisol levels than group-held bats,
but MCBC, free cortisol, and blood glucose levels showed no effect of social holding condition. Our findings
demonstrate that capture time should be minimized and suggest that little brown bats should be handled and
released within 30 min of capture as means of reducing stress. Further, solitary holding did not appear to increase
stress measures, which supports holding bats individually after capture, instead of in groups, to reduce risk of
pathogen and parasite transmission

No full textAnthropogenic noise decreases activity and calling behavior in wild mice
No full textBackground Animals rely on sound to mediate a myriad of daily activities, and anthropogenic noise is a pollutant that alters the natural soundscape within which they are active. As human infrastructure expands, broadband anthropogenic noise increases, which can affect behaviors of free-living nocturnal animals. Mice are nocturnal animals that produce ultrasonic calls as part of their behavioral repertoire. Methods We assessed effects of anthropogenic and natural noise on the behaviors of wild deer mice (Peromyscus maniculatus) and woodland jumping mice (Napaeozapus insignis), two species of mice that produce ultrasonic calls. We measured activity, foraging behavior at a foraging tray, and calling behavior to broadcasts of natural and anthropogenic noise, compared to a baseline with no broadcasting, at 25 focal areas in the Southern Appalachian Mountain Range of North Carolina, USA. Results Deer mice exposed to anthropogenic noise spent less time in focal areas with broadcasted anthropogenic noise. Mice took longer to begin foraging in the presence of anthropogenic noise, they spent less time at the foraging tray, and left fewer husks but consumed the same number of seeds as mice exposed to natural noise. Deer mice were less likely than woodland jumping mice to be the first to enter the focal area and approach food when in the presence of anthropogenic noise. Both species produced few ultrasonic calls in the presence of broadcasted natural and anthropogenic noise compared to their baseline level of calling. We present the first calls recorded from woodland jumping mice. Conclusion Anthropogenic noise affects activity, foraging behavior, and calling behavior of nocturnal mice. Natural noise also affects the calling behavior of mice. Mouse species respond differently to anthropogenic noise, with deer mice appearing more sensitive to anthropogenic noise than woodland jumping mice. Responses to noise could have important effects on the ecology of mice and these two species respond differently. Species differences should be considered when mitigating the effects of noise in conservation ecology
