The Siberian hamster is a model organism for studying seasonal biological rhythms. They breed during the spring and early summer, but as fall approaches, their bodies change dramatically. The hamsters ...

Analysis of the first fully-sequenced genome of the Siberian hamster shows how these small, seasonal breeders adapt their bodies and energy usage to survive the winter. The research, published this ...

Many animals, including humans, have internal clocks and calendars to help them regulate behavior, physiological functions and biological processes. Although scientists have extensively studied the ...

Many animals experience marked seasonal fluctuations in environmental conditions. In response, animals display adaptive alterations in physiology and behaviour, including seasonal changes in immune ...

Siberian hamsters respond to food deprivation or restriction by increasing their food hoarding and do so proportionately to the degree of body mass (fat) loss. These data suggest that Siberian ...
