Brown bears store fat for a good winter

Seasonal lipid adjustments in body fat go hand in hand with hibernation (Photo Jon M. Arnemo)

Some people would like to hibernate through the winter - just like brown bears do every year. Hibernating bears lower their body temperature only slightly (2-5 ° C) to a value between 30 ° C and 36 ° C. The role of body fat composition on winter hibernation was now examined for the first time in wild brown bears by an international team led by researchers from the University of Strasbourg and the Vetmeduni Vienna. The two most important findings: unsaturated fatty acids play an important role during hibernation and the composition of the fat stores of large hibernating animals is very similar to that of small hibernators. As shown by Sylvain Giroud and his co-authors, the shift in lipid composition appears to be an evolutionarily conserved hibernation phenomenon that appears independent of body mass and body temperature.

The article “Lipidomics Reveals Seasonal Shifts in a Large-Bodied Hibernator, the Brown Bear 1” by Sylvain Giroud, Isabelle Chery, Fabrice Bertile, Justine Bertrand-Michel, Georg Tascher, Guillemette Gauquelin Cook, Jon M. Arnemo, Jon E. Swenson , Navinder J. Singh, Etienne Lefai, Alina L. Evans, Chantal Simon and Stéphane Blanc was published in Frontiers in Physiology.

In Svalbard reindeer the inner clock is always ticking

All animals have an internal clock with a cycle length that deviates slightly from 24 hours, and that synchronizes based on cues from external "timers", usually the daily change from day to night. It was uncertain whether this internal clock also functions in the Polar Regions, where there is continuous darkness for months during winter and steady light in the summer. A research team led by Walter Arnold from the Research Institute of Wildlife Ecology at the Vetmeduni Vienna examined this question for wild reindeer on Svalbard, using for the first time a high-resolution telemetry system. They studied not only the behavior, but also the physiology of the animals. They found that - contrary to earlier findings - a circadian rhythm persists throughout the year.

The article “Circadian rhythmicity persists through the Polar night and midnight sun in Svalbard reindeer 6” by Walter Arnold, Thomas Ruf, Leif Egil Loe, R. Justin Irvine, Erik Ropstad, Vebjørn Veiberg and Steve D. Albon was published in Scientific Reports.
