Shifts in population density centers of a hibernating mammal driven by conflicting effects of climate change and disease

Justin G. Boyles,
Virgil Brack,
Katie E. Marshall
et al.

Abstract: Populations wax and wane over time in response to an organism's interactions with abiotic and biotic forces. Numerous studies demonstrate that fluctuations in local populations can lead to shifts in relative population densities across the geographic range of a species over time. Fewer studies attempt to disentangle the causes of such shifts. Over four decades (1983–2022), we monitored populations of hibernating Indiana bats (Myotis sodalis) in two areas separated by ~110 km. The number of bats hibernating in … Show more

“…Contrary to our predictions, despite the relatively cool ambient temperature, the “active” season for M. lucifugus was similar in duration to that observed for numerous populations a further south (Table 3). However, many of the published studies we reviewed for comparison were carried out more than three decades ago and the population may now experience shorter hibernation periods than originally reported (Boyles et al, 2024).…”

“…However, many of the published studies we reviewed T A B L E 3 Dates for emergence and immergence of Myotis lucifugus at winter hibernacula throughout their range, organized on the order of earliest emergence. for comparison were carried out more than three decades ago and the population may now experience shorter hibernation periods than originally reported (Boyles et al, 2024). For reproductive females, spring emergence initiates the onset of gestation (Wimsatt, 1944), and moving from the cooler hibernacula into warmer maternity roosts allows females to take advantage of passive warming, further promoting fetal development (Geiser & Drury, 2003).…”

“…Increased temperature during arousal periods inhibits fungal growth (Forney et al 2022), suggesting the increase in arousal frequency could be a host response to fungal infection. Some bat populations have increased in their southern range, despite WNS and decreases in the north, perhaps due to the longer availability of insects increasing their hibernation resources (Boyles et al 2024). Population stabilisation and increase of tricoloured bats (Perimyotis subflavus) in the presence of WNS have been associated with greater use of colder microclimates within their hibernacula (Loeb & Winters 2022).…”
