What makes an animal swap between summer and winter coats?
Is it timed by a biological clock?
Is it temperature?
Or is it just diet maybe?
Take an arctic fox for example. It sheds its winter coat going into summer, if you move that fox to a warmer climate will the foxes fur stay perpetually in “summer mode”.
In: Biology
The entire nature shifts between seasons. That includes the plants, trees and flowers. All fauna and flora.
It’s a biological clock. They sense temperature changes, sunlight, duration of day and night, angle of sun in the sky and shadows. Its a complex, synchronized system….
(Humans are among the very few species that can reproduce all year long. For most species reproduction is seasonal).
