Explanation:

Most mammal and bird species inhabiting temperate and arctic environments undergo periodical moults one to three times a year. The moults replace worn out and old hairs or feathers and result in new, structurally different coats better suited for the upcoming season (Ling, 1972). In the group of species that we focus on here, brown or greyish brown summer coats are annually shed and replaced with new fully or mostly white fur or plumage. Therefore, in SCC species, individuals are capable of producing multiple phenotypic morphs (polyphenism; Mayr, 1963), i.e. winter white and summer brown colour morphs, and therefore SCC species fundamentally differ from others exhibiting non‐seasonal discrete
