Coat color variation in North America generally follows which geographical ecological rule?
Answer
Gloger’s rule
Coat coloration in North American wolves shows distinct geographical patterns that align with Gloger’s rule. This rule suggests that within a species, populations living in more humid or warmer environments tend to exhibit darker pigmentation compared to those in drier or colder environments. In the North American context, this translates to white wolves being predominant in the Canadian Arctic regions, while the coloration transitions to predominantly gray as one moves further south into less extreme, often wetter, territories.
