Abstract The purpose of this chapter is to demonstrate a method to generate your own presence and absence data and distribute those samples using specific ecological characteristics found in remotely sensed imagery.

Studies carried out for nearly 40 years in one place have enabled us to evaluate the gener- ality of this focus. Early observations in one high-altitude, rocky-bottom

Circadian rhythms of body temperature were evident during deep torpor in 11 of 12 individuals. The mean period was 23.94 hours. Circadian cycles of oxygen consumption were apparent in Jive of 14 marmots. Arousal tended to occur during the increase phase of the cycle. This report may be the Jirst to
