Abstract
Kseniia Kravchenko and Joanna Furmankiewicz, from the University of Wrocław, Poland, used continuous acoustic monitoring and temperature measurements inside and outside the roost of the common noctule bats (Nyctalus noctula) to understand winter activity patterns. They focused on a northern region that has only been used for hibernation in recent decades. The bats displayed circadian periodicity of nighttime activity and daytime rest, but only when temperatures were above 0 °C. Below 0 °C — temperatures that would see high costs of flight and low presence of food — the bats seemed to remain in deep torpor. This potential flexible adjustment to environmental conditions may explain the common noctule’s success in recent northward expansion.
