The yellow-bellied marmot spends approximately 80% of its life in a burrow. Burrows provide protection from the rigors of the environment, pred- ators and other marmots. They provide a hibernaculum in winter and may func- tion as a nursery in summer. Selection of a burrow site is therefore an import

Using a densimeter technique, a kinetic analysis was made, employing both entrance and exit studies, of the permeability of erythrocytes of brook trout (Salvelinus fontinalis), rainbow trout (Salmo gairdneri), German brown trout (Salmo trutta) and cutthroat trout (Salmo clarki) to glycerol, ethylene

The kinetics of both swelling and shrinking of erythrocytes of the yellow-bellied marmot, golden-mantled ground squirrel, chipmunk, deer mouse, long-tailed vole, montane vole and western jumping mouse indicate that glycerol, ethylene glycol, urea and thiourea penetrate by means of facilitated diffus

A comparison of blood values of American goldfinches during summer and winter in Michigan reveals an increase in blood characteristics of winter individuals similar in extent to that of winter pine siskins, raising the possibility that the blood parameters of high altitude birds reflect adjustments

Seasonal changes in the body weights of yellow-bellied marmot (Marmota flaviventris) populations were studied for 8 years in western Colorado. Marmots may be classified by size into four age groups: juvenile, yearling, 2-year-old, and 3-year-old or older, each group with significantly different mean

The relationship between female reproductive success and both spring food and hibernacula resources was examined in a high—altitude population of yellow—bellied marmots (Marmota flaviventris). The number of offspring a female weaned was significantly associated with the estimated number she could po

Caloric equivalents for aboveground parts of Rocky Mountain subalpine and alpine herbaceous plants averaged 4,859 cal/g ash-free oven-dry weight. Ash content averaged 9.8% for 17 forbs. Both caloric content and ash content ranged higher than values for alpine species from New Hampshire.
