Indeed, we observe almost no weight gain in juveniles throughout autumn capture season, which contrasts strongly with adults.

In the most optimistic scenario, Daubenton’s bats are taking advantage of this shift, fattening up quickly, and diving into the safety of the hibernaculum as soon as they can. However, it could also be an attempt to make the best of a bad job...

Surprisingly, Daubenton’s bats (at the same site and over the same time-frame) have EXTENDED their hibernation duration, with adult bats entering the hibernaculum much earlier than they used to (males: 2 days/year, females 1 day/year). But why? We think in response to their prey…

With temps rising, winters are getting milder and shorter, causing many organisms to extend their active periods in autumn and spring.
Natterer’s bats are doing this at an exceptional rate! Entering later, emerging earlier, reducing their hibernation period by nearly a month in just over a decade!

Systematic genetic monitoring of the species would be an incredibly valuable tool to track population dynamics, and we hope our work inspires the establishment of such a program! (6/6)
Big shoutout to the entire team that made this work possible! (none on Bsky unfortunately)

Turns out, this is not the case, as we found no mother-offspring pairs in any of the individuals sampled together, or even across the entire 4 year dataset. (3/6)
