Landscape condition influences energetics, reproduction, and stress biomarkers in grizzly bears

Abstract Environmental change has been shown to influence mammalian distribution, habitat use, and behavior; however, few studies have investigated the impact on physiological function. This study aimed to determine the influence of landscape condition on the expression of target proteins related to...

One stress related protein, complement C3, was positively influenced by increased percent conifer.
