Abstract

Waking up to global warming Climate change affects the timing of regular events of plant and animal life, such as budding, migration and hibernation, as well as population dynamics and morphology. It is difficult to monitor all these interacting factors at once, but an extended life-history study of a hibernating mammal — a yellow-bellied marmot (Marmota flaviventris) population in a subalpine habitat in the Upper East River Valley, Colorado — provides data suited to the task. Climate change over the period 1976–2008 has caused earlier emergence from hibernation, lengthening the animals' growing season so that they are now heavier when they start to hibernate. At the same time, the fitness of large individuals has increased, leading to a rapid increase in population size. As Marcel Visser explains in the accompanying News & Views, the major challenge in climate-change ecology is to predict the impact of future climate change on populations. This work on marmots provides the type of data needed to achieve that aim.
