Sagebrush steppe systems represent one of North America’s greatest conservation challenges. Shrinking habitat and declining animal populations have prompted researchers to fill gaps in our understanding of the ecology of this system, particularly at a scale relevant to individual animals. What animals eat and why are fundamental questions linked to habitat quality and use. We investigated the temporal and spatial heterogeneity of the dietary quality of food to better understand habitat use by a sagebrush specialist, the pygmy rabbit (Brachylagus idahoensis). Within a foraging patch, pygmy rabbits selectively browse on individual Wyoming big sagebrush (Artemisia tridentata wyomingensis) that are …
