Cold Fat Adaptations Hot/Cold Climates Hot High Sa:V

Organisms in hot climates have high surface area to volume ratios and light fur/feathers for cooling, while those in cold climates have low surface area to volume ratios, insulating fat, and hibernation.

Organismos em climas quentes têm alta relação área de superfície-volume e pelos/penas claras para resfriamento, enquanto em climas frios têm baixa relação área de superfície-volume, gordura isolante e hibernação.

Front Adaptations for very hot/cold climates
Back

    • hot (high SA:V to max cooling, pale fur and feathers that reflect radiation)
    • cold (low SA:V, thick layer of insulating fat under skin and hibernation (build up fat stores and lower metabollic rate to pass worst of cold weather in sleep)
