Résumé
Periods of mating, gestation, parturition, appearance of young from the burrow, and litter size differ as a result of latitude and altitude. During summer, marmots accumulate fat reserves, and weight loss during hibernation can be as much as 37 percent of total body weight. Marmots are monestrous, having one estrous cycle per year.
