Stress-associated metabolites vary with both season and habitat across populations of a climate sentinel species
ABSTRACTRelating physiological stress to habitat quality could refine conservation efforts. Habitat quality, which is often inferred from patch occupancy or demographic rates, might be measured in a more timely and nuanced way using metrics of physiological stress. To understand whether stress-assoc...

ABSTRACTRelating physiological stress to habitat quality could refine conservation efforts.
