Prey Switching of Sympatric Canids in Response to Variable Prey Abundance
Autor: Peter L. Meserve, John A. Yunger, Lynda A. Randa, Douglass M. Cooper
Publikováno v: Journal of Mammalogy. 90:594-603
We investigated the effects of fluctuating prey numbers on the foraging strategies and potential mechanisms for coexistence of 2 sympatric predators, coyotes (Canis latrans) and red foxes (Vulpes vulpes), in a heterogeneous environment in northeaster

We investigated predation risk and competition as they affected small-mammal foraging behavior in semiarid north-central Chile. Giving-up densities (GUD) of seeds were used to measure the foraging activity of the three most common small mammals at th

RESPONSE OF TWO LOW-DENSITY POPULATIONS OF PEROMYSCUS LEUCOPUS TO INCREASED FOOD AVAILABILITY
Autor: John A. Yunger
Publikováno v: Journal of Mammalogy. 83:267-279
Studies of food supplementation in small mammals often result in significant increases in population density. These numerical responses to increased food availability may interact with other variables, such as predation, territoriality, and emigratio

Role of Biotic Interactions in a Small Mammal Assemblage in Semiarid Chile
Autor: Luis C. Contreras, John A. Yunger, Fabian M. Jaksic, Peter L. Meserve, Julio R. Gutiérrez
Publikováno v: Ecology. 77:133-148
The role of biotic interactions including vertebrate predation and interspecific competition was studied among members of a semiarid small mammal assemblage in a long-term field manipulation in north central Chile. Fences and netting selectively excl

Heterogeneous Responses of Small Mammals to an El Nino Southern Oscillation Event in Northcentral Semiarid Chile and the Importance of Ecological Scale

Publikováno v: Journal of Mammalogy. 76:580-595
A prolonged El Nino Southern Oscillation (ENSO) event during 1991–1992 with three times the normal annual 85-mm rainfall was accompanied by major changes in numbers of small mammals at a semiarid Mediterranean site in northcentral Chile. Several de

Movement and spatial organization of small mammals following vertebrate predator exclusion
Autor: John A. Yunger
Publikováno v: Oecologia. 139(4)
Predation directly changes the demographics of prey, generally through a numerical decrease. An indirect effect of predators is alteration of movements and spatial patterns of prey. The relationship between these direct and indirect effects can be te

The aim of this study was to identify factors associated with malignant etiologies of childhood peripheral lymphadenopathy and to construct a model that may be used to assess the risk of malignancy.The medical records of 60 consecutive patients 18 ye

Predation, Competition, and Abiotic Disturbance: Population Dynamics of Small Mammals
Autor: John A. Yunger
Predation and food availability have been implicated in annual non-cyclic fluctuations of vertebrate prey at mid-latitudes. The timing and magnitude of these factors are unclear due to a lack of large-scale field experiments, little attention to inte
