Bears pack on fat when preparing to hibernate each winter. To avoid the health risks often associated with human obesity, the bears have specialized gut microbiota that takes in more energy from food in the summer.
Although the appearance of plants and trees are known to change between seasons, a new study from Temple University offers recommendations for designing landscapes in temperate climates that people can enjoy year-round. This includes planting evergreens and plants that produce colorful berries.
Red deer living across Europe prefer to graze on grasses and short shrubs, but when food sources are covered by feet of snow and ice, their stomachs shrink and their bodies take in nutrients more efficiently than in more plentiful summers.
Scientists have long beleived that three species of Madagascan lemurs were the only primates that hibernate. But new findings suggest that pygmy slow lorises, a relatively small primate that belongs to the so-called wet nosed classification from Southeast Asia, take long wintertime naps, too.
As the weather starts to get colder, female hamsters may start acting out. That is because different levels of melatonin actually trigger a sex hormone known to cause aggression, suggesting sex hormones play an important role in controlling such behaviors.
