Colorado State researcher thinks Groundhog Day is about fatty acids rather than traditional tricks of light and shadow

. He speculates that linolenic acid levels in American groundhogs affect whether they emerge from hibernation early, rather than the presence or absence of their shadows.

Marmots and other hibernating animals spend the warm season gorging on leafy plants, seeds and nuts that contain varying amounts of these fatty acids. Autumnal temperature drops trigger a series of physiological events that can cause hibernation.

The 2000 Fulbright award is Florant's second and one of only two given to American scholars to work in Austria. He also received a Fulbright for research in France in 1983-84.
