Research

Project Details

Terry Root utilized her fellowship to forecast the possible ecological consequences of global warming. Her research group focused on increasing the understanding of the basic physiological/ecological mechanisms that may be shaping the northern range boundaries of North American animals, particularly wintering birds.

Her allozyme and genetic studies of Northern Cardinals revealed that there were no recognizably distinct populations, thereby strongly suggesting that the geographic variation in physiology across their winter range is due to individual acclimatization. The reason that the northern boundaries of wintering ranges of various birds are not farther north is apparently due to the fact that enough fat cannot be stored by individuals in more northerly locations to sustain them throughout the cold night. This provided insight into the mechanism limiting species' northern range boundaries, which in turn allowed forecasting of range shifts with warming.

The similarity in individuals indicates that temperature, rather than day length, is the more important factor. Therefore, as the globe starts warming, these birds could potentially move northward. The locations of the northern boundaries of the winter ranges of birds shift annually. These results indicate that in warmer years individuals of at least some bird species winter farther north than they do in colder years.

Biography

Terry Root studies the ecology and physiology of wintering North American songbirds to learn how temperature affects the location of their ranges. The goal of her research is to increase understanding of how animals may respond to rapid climate change. For instance, species with ranges limited by temperature may be able to shift their ranges northward immediately, while species with ranges limited by vegetation will not be able to shift quickly. The latter will need to wait many decades for the vegetation to change. Such differential movement of species could cause a tearing apart "of species communities as we know them today."
