Employing new methodology, the study investigates the link between climate change, demography and life history in the yellow bellied marmot over a 30 year period. Results indicate in response to warming conditions, marmots emerge earlier from hibernation and wean young sooner, leading to a longer growth season and higher body mass at hibernation—resulting in a significant increase in population size.
