A technique for using patch giving up densities to investigate habitat preferences, predation risk, and interspecific competitive relationships is theoretically analyzed and empirically investigated in a community of four Arizonan granivorous rodents.
Hazardous duty pay and the foraging cost of predation
The concepts and research associated with measuring fear and its consequences for foraging, including titrating for fear responses in foragers has some well-established applications and holds promise for novel methodologies, concepts and applications are reviewed.
The Ecology of Fear: Optimal Foraging, Game Theory, and Trophic Interactions
This work extends foraging theory to consider a predator-prey game of stealth and fear and then embeds this game into the modeling of predator- prey population dynamics, which identifies the endpoints of a continuum of N-driven (population size) versus μ- driven (fear) systems.
Vigilance, patch use and habitat selection: Foraging under predation risk
A model for predicting how an optimal forager should jointly use vigilance and GUD to trade-oV food and safety while feeding from a food patch and the amount of food left by a forager in a depletable food patch is presented.
Tragedy of the commons as a result of root competition
1  We develop and test a game‐theoretic model for considering the effects of intra‐ and interplant competition on root proliferation and reproductive yield. 2  We predict that if space and resources
The Selective Interactions of Dispersal, Dormancy, and Seed Size as Adaptations for Reducing Risk in Variable Environments
A model explores how changes in the number of independent environmental patches, the probability of favorable conditions, the radius of dispersal, and spatial and temporal autocorrelation of environmental conditions alter selection on the interacting syndrome of seed traits.
Desert rodent community structure : a test of four mechanisms of coexistence
Four mechanisms of coexistence are considered that may contribute to the diversity of desert granivorous rodent communities and best explained the presence of Perognathus amplus, Dipodomys merriami, and Spermophilus tereticaudus in the community.
Foraging : behavior and ecology
This volume brings together twenty-two experts from throughout the field to offer the latest on the mechanics of foraging, modern foraging theory, and foraging ecology, and will be the definitive guide to the field.
Environmental Heterogeneity and the Coexistence of Desert Rodents
"The desert is a simple ecosystem. You can imagine that you can understand it . ... " I This, perhaps, more than any other reason has drawn community ecologists to study desert rodents. In the five
