Just Five More Minutes: News On the Evolution of Hibernation
An international research team led by Senckenberg scientists Dr. Dimitrios-Georgios Kontopoulos and Prof. Dr. Michael Hiller has investigated the evolution of different types of torpor – the temporary sharp drop in metabolism and body temperature to conserve energy – in numerous mammals and birds. Their study, recently published in the scientific journal “Functional Ecology,” shows that the “energy-saving mode,” which is widespread in the animal kingdom, has emerged several times independently of each other in different groups of animals over the course of evolution. According to the study, the two main torpor types – the short-term “daily torpor” lasting up to 24 hours and the markedly more prolonged hibernation –…

Sea More Species? Genetic Differences Discovered in Blue Whale Populations
A research team from the Senckenberg Biodiversity and Climate Research Center (SBiK-F), the former LOEWE Center for Translational Biodiversity Genomics (TBG), and Goethe University Frankfurt has gained fascinating genetic insights into the evolution of the largest animal on earth, the iconic blue whale (Balaenoptera musculus). Their study, published in the journal “Molecular Ecology,” provides evidence that blue whales from the North Pacific and North Atlantic may represent separate subspecies. Conservation measures should be specifically adapted to the individual populations, according to the researchers from Frankfurt. Blue whales (Balaenoptera musculus) can reach a length of up to 30 meters and weigh over 180 tons, making them the largest known whale species…
