Territoriality and mating system of California voles
(1) In this study I used radiotelemetry to examine patterns of space use by free-ranging California voles (Microtus californicus) both before and after the provision of supplemental food (freshExpand

Eastern chipmunks increase their perception of predation risk in response to titmouse alarm calls
Vocally signaling a predator's presence through alarm calls creates public information regarding risk in the environment. If having this information confers an advantage, eavesdropping behavior, theExpand

Defining the Scientific Issues
This chapter introduces the problems with which the book deals and lays out the structure of the analysis. We introduce the needs, both scientific and practical, for developing a new theory ofExpand

Abstract Spatial heterogeneity in risk is a critical component of predator-prey interactions. However, at small spatial scales, it is difficult to quantify predation risk without altering it. We usedExpand

Experimental analysis of aggression and spacing behavior in California voles
Spacing behavior is thought to be an important means of population regulation, but the phenomenon itself is poorly understood, especially in cryptic, secretive small mammals, in this study 1 examinedExpand

Effects of density and season on the population rate of change in the meadow vole
We developed an empirically based model of density-dependent vole population growth based on experimental data on population dynamics of Microtus pennsylvanicus in large field enclosures. StatisticalExpand

Sexual Dimorphism and Mating Systems in Voles
Here we respond to the criticism that use of body length is an incorrect and misleading measure of sexual dimorphism in body size (Boonstra et al., 1993, J. Mammal., 74:224–229). Despite theExpand

Does social behavior drive vole cycles? An evaluation of competing models as they pertain to California voles
The literature contains a number of verbal and mathematical models that assert that social behavior drives the multiannual density cycles characteristic of many vole species. Many of the assumptionsExpand
