This means that animals like the raccoon can quickly become active again if temperatures rise or the snow melts. [1] Other animals that winter rest are badgers . Although a bear's body temperature decreases less than that of other mammals which undergo true hibernation, mostly changing around 6-7 degrees Celsius, this is a result of their large ...
On the other hand, dormancy can be triggered after a normal growing season by decreasing temperatures, shortened day length, and/or a reduction in rainfall.
