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
For many species, it’s triggered by the days becoming shorter/longer. Temperature typically is not a factor.
