Spatiotemporal Variation in Survival of Male Yellow-bellied Marmots

Variation in vital demographic (e.g., survival) rates of males can influence population dynamics, but the male segment of the population is frequently ignored in ecological studies of mammals. Using a multistate capture– mark–recapture model and 44 years (1962–2006) of data from 17 habitat patches, we investigated spatial and temporal variation in age-specific survival rates of male yellow-bell...

Olfactory Predator Discrimination in Yellow-Bellied Marmots

Many mammals discriminate the scents of their predators (reviewed in Apfelbach et al. 2005) and this trait may be heritable (there is genetic variation in the degree of response to synthetic fox [Vulpes vulpes] odor in rats [Rattus norvegicus], Rosen et al. 2006). The mechanism underlying this identification may be relatively experience-independent, or it may rely on specific experience with pr...

Why do yellow-bellied marmots call?

Armitage is at the Department of Systematics and Ecology, University of Kansas, Lawrence, KS 66045, U.S.A. When we see animals do things that are potentially risky, such as alarm calling around predator...
