How Climate Change Alters Rhythms of the Wild

The more scientists look, the more connections they see between shifts in climate and changes in animal behavior and populations. On page 854, researchers report that while the number of dippers in a population in southern Norway fluctuated between 1978 and 1997, it followed an upward trajectory that was closely associated with an atmospheric pressure system called the North Atlantic Oscillation and the milder winter temperatures it brought. These and other findings pouring in could have huge implications for conservation.
