Daubenton's bats are now entering hibernation a month earlier than 13 years ago without increasing fat reserves, highlighting shifting survival challenges linked to climate change. doi.org/g955mn
An unexpected reaction to climate change: Daubenton's bats are hibernating for longer
The days are getting shorter, the temperatures are dropping. Numerous animals are migrating south, others are seeking their hibernacula—including bats.

Proud to present our latest 🦇 paper! Using 13 years of data, we show that hibernation timing has shifted dramatically in two bat species, but in opposite directions 😮
Huge congrats to Gabi, Frauke, and the whole team.

Whose poo?
New research shows bats are more likely to investigate new home if it smells of a friend's poo.
Hmm. Let's not try this at home humans!

Great opportunity!
One more month to the application deadline for a PhD position studying active sensing collectives in the wild with multiple sensors.
Do you like this weird mix of animal behaviour, coding, and cool gadgets? Then check out the thread to see what our lab does and more on the position itself!!

We're looking for a PhD candidate who will characterise what echolocating agents do in groups using a multi-sensor rigs in the field. Wouldn't it be cool to finally figure out how bats manage their calling and flying - and even reconstruct what they may be hearing to make these decisions? 5/n

Equally happy to share our new paper!
It turns out malaria's little brother is infecting Myotis bats 🦇 and bat flies 🪰 all over Europe. Definitely an under-appreciated pathogen that deserves some more study and attention.

Now that I sort of know my way around here, I guess it's finally time for an intro post. I'm a postdoc at the University of Greifswald working on all things batty! 🦇
I'm terrible at posting regularly, but enjoy lurking along and reading about new pubs/discussions and all the other goings on.
