Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not ...
During winter dormancy, plant metabolism comes to a virtual standstill, due in part to low temperatures that slow chemical activity. [1]Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped.
The energy expenditure of chasing and fighting during the breeding season can result in a buck losing an immense amount of weight, with some research documenting losses of as much as 20% of body weight with some sources showing body mass losses of up to 30%. [11] On average, a buck before breeding season can weigh up to 180 pounds (82 kg).
During the winter season, the zookeeping team provides routine care while adapting to the needs of several species. All animals remain on-site throughout the year in their various homes.

The white-tailed ptarmigan has a diet of buds, leaves, flowers and seeds. The nest is a simple depression in the ground in which up to eight eggs are laid. After hatching, the chicks soon leave ...
Hence, seasonal breeders can be divided into groups based on fertility period. "Long day" breeders cycle when days get longer (spring) and are in anestrus in fall and winter. Some animals that are long day breeders include ring-tailed lemurs, horses, hamsters, groundhogs, and mink. "Short day" breeders cycle when the length of daylight shortens ...
resting, for a bud that forms at the end of a growth season, and then lies dormant until the onset of the next growth season; dormant or latent, for buds whose growth has been delayed for a rather long time. The term is usable as a synonym of resting, but is better employed for buds waiting undeveloped for years, for example epicormic buds;
