One Species Hibernates Shorter, the Other Longer: Rapid but Opposing Responses to Warming Climate in Two Sympatric Bat Species
1 Introduction Climate change is altering the timing of seasonal biological events, such as migration, hibernation and reproduction, across a wide range of taxa and ecosystems (Parmesan and Yohe 2003; Thackeray et al. 2016). In temperate and cold environments, hibernation is a key phenological trait for many mammals, enabling them to survive adverse winter conditions (Geiser 2021).
In‐situ responses of temperate‐zone bats to climate change
INTRODUCTION Bats are highly successful mammals from an evolutionary perspective. In the Eocene, the forests of the northern hemisphere were home to bats that were morphologically and behaviorally remarkably similar to the bats that live there today.
Die Thermomechanik roter Blutzellen und der Winterschlaf
Jedes Jahr verschlafen Millionen von Tieren die kalten Wintermonate – doch wie schafft es ihr Körper, bei niedrigen Temperaturen weiterhin zu funktionieren? Wir haben nun die mechanischen Eigenschaften von roten Blutzellen bei Menschen sowie von zwei Fledermausarten untersucht, von denen eine Winterschlaf hält, während die andere ganzjährig aktiv ist.

Heat over heritability: Increasing body size in response to global warming is not stabilized by genetic effects in Bechstein's bats
Temperature conditions and changes in body size Ambient temperature data were provided by the Bayerische Landesanstalt für Wald und Forstwirtschaft (LWF) from the local meteorological station ‘Waldklimastation’ (WKS; ID WUE57) and the DWD Climate Data Center (meteorological station ‘Würzburg’; ID 0570558).
Mitochondrial DNA (mtDNA) reveals that female Bechstein’s bats live in closed societies
Abstract We present a microgeographic analysis of mitochondrial DNA (mtDNA) in Bechstein’s bats using three sources of control region sequence variability, including a novel mtDNA microsatellite, to assess individual relatedness both within and among 10 maternity colonies. Comparison of marker variability among 268 adult females revealed little genetic variability within each colony. However, most colonies were clearly distinguished by colony-specific mitochondrial haplotypes (total n = 28).
