Pre-Hibernation Behavior of Free-Living Hoary Marmots, Marmota caligata

Mammalia, 2023
Abstract Hoary marmots (Marmota caligata) dig burrows in alpine meadows rich in forage as ready refuge from potential predators. Refuge burrows enable hoary marmots to engage in risk-sensitive foraging when they are away from more secure resting burrows on talus slopes.

Social structure and facultative mating systems of hoary marmots (Marmota caligata)
Molecular Ecology, 2007AbstractMate‐choice theory predicts different optimal mating systems depending on resource availability and habitat stability. Regions with limited resources are thought to promote monogamy. We tested predictions of monogamy in a social rodent, the hoary marmot (Marmota caligata), at the northern climatic extreme of its distribution.

Isolation and characterization of microsatellite markers in hoary marmots (Marmota caligata)
Molecular Ecology Notes, 2004AbstractMicrosatellite loci were developed from hoary marmots (Marmota caligata) to aid in the investigation of the social structure and mating system of this species. Seven of the microsatellite loci developed were found to be moderately polymorphic with between two and seven alleles per locus.

Foods of the Hoary Marmot on Kenai Peninsula, Alaska
American Midland Naturalist, 1975Plant compositions of the diet and habitat of Marmota caligata were determined on three alpine mountains on the Kenai Peninsula, Alaska, in the summers of 1971 and 1972. Vetches (Astragalus and Oxytropis), sedges (Carex), fleabanes (Erigeron), fescues (Festuca), mosses, lichens (Cladonia),, dryas (Dryas) and willows (Salix) collectively made up about ...

Ecology of Paternal Behavior in the Hoary Marmot (Marmota caligata): An Evolutionary Interpretation
Journal of Mammalogy, 1975Male hoary marmots living in isolated colonies at Mount Rainier National Park demonstrated a significantly greater involvement with their infants than did males living in a larger, more interactive social situation. Paternal behavior correlated inversely with frequencies of extrapaternal social interaction.

I used 8 years of mark-recapture data to test alternative hypotheses about the relative influence of winter climate, social structure, and life history on survival, reproduction, and population dynamics of hoary marmots (Marmota caligata) in the southwest Yukon.
