Characterization of how snow properties vary across spatial scales using correlation lengths and variogram analysis

Complete or near-complete elimination of local populations due to environmental catastrophe

Areas where organisms can persist during periods of unfavorable climate change

Differential behavioral responses based on whether female marmots are reproductive or non-reproductive

Valley wind that develops due to differential heating between valley floor and surrounding slopes, typically flowing upslope during daytime

Analysis of carbon and nitrogen isotope ratios to determine trophic position and dietary composition

Predicts that a species' high-elevation range limit is determined by harsh abiotic conditions whereas its low-elevation range limit is set by antagonistic species interactions
