Extreme Weather Events Sync Rise and Fall of Arctic Populations

Climate change and changes in weather can affect species in many ways. From altering migration patterns, to varying plant growth leading to deviating diets, to extending or decreasing hibernation periods, climate can ultimately influence the success of a species. In an attempt to study some of these effects, a group of Norwegian scientists have found that extreme climate events can cause population fluctuations not only among single species, but also in a relatively simple high arctic community.
