Heavily-hunted wolf populations have elevated stress, reproductive hormones, study reveals

Most of this is not particularly surprising (although it is always good to check your assumptions at the door), but the evolutionary consequences was something new (to me).

[Being hunted] can disrupt a wolf pack’s complex social structure, alter normal reproductive behaviour and introduce chronic stress that “may have evolutionary consequences,” the study found. Hunting can also decrease pack size, resulting in altered predation patterns, increased time spent defending kill sites from scavengers and may lead to increased conflict with humans and livestock, the study added.
