Bioenergetic Prediction of Climate Change Impacts on Northern Mammals
Climate change will likely alter the distribution and abundance of northern mammals through a combination of direct, abiotic effects ( e.g., changes in temperature and precipitation) and indirect, biotic effects ( e.g., changes in the abundance of resources, competitors, and predators).

Climate change will likely alter the distribution and abundance of northern mammals through a combination of direct, abiotic effects ( e.g., changes in temperature and precipitation) and indirect, biotic effects ( e.g., changes in the abundance of resources, competitors, and predators). Bioenergetic approaches are ideally suited to predicting the impacts of climate change because individual energy budgets integrate biotic and abiotic influences, and translate individual function into population and community outcomes. In this review, we illustrate how bioenergetics can be used to predict the regional biodiversity, species range limits, and community trophic organization of mammals under future climate scenarios. Although reliable prediction of climate change impacts for particular species requires better data and theory on the physiological ecology of northern mammals, two robust hypotheses emerge from the bioenergetic approaches presented here.
