A test of the ‘hot’ mustard extraction method of sampling earthworms
Abstract Earthworm densities in soil are difficult to quantify. Part of the problem is that they are incorporated closely into the soil structure, which makes their extraction tedious and timeExpand
Body Size and Coexistnce in Desert Rodents: Chance or Community Structure?
We use a simple test to evaluate the null hypotheses that desert rodent communities are composed of species assembled at random with respect to body size. This hypothesis is unequivocally rejectedExpand
Interpatch movements in spatially structured populations: a literature review
We used published data of individuals moving among habitat patches to answer questions pertaining to frequency of interpatch movements and subsequent effects on population dynamics. A review of 415Expand
Connectivity in an agricultural landscape as reflected by interpond movements of a freshwater turtle.
Connectivity is a measure of how landscape features facilitate movement and thus is an important factor in species persistence in a fragmented landscape. The scarcity of empirical studies thatExpand
Foraging of Gray Squirrels on an Urban‐Rural Gradient: Use of the Gud to Assess Anthropogenic Impact
Responses of organisms to urbanization may involve adjustments in behavior. To qualify such behavioral plasticity we measured the degree to which gray squirrels (Sciurus carolinensis) exploitedExpand
Bumble Bee Colonization, Extinction, and Reproduction in Subalpine Meadows in Northeastern Utah
The distributional patterns of six bumble bee (Bombus) species in discrete subalpine meadows in Utah were studied over the course of a summer. Data on the movements of individuals were obtainedExpand
Seed Removal Experiments on Desert Rodents: The Microhabitat by Moonlight Effect

Influence of herbivorous mammals on an old-field plant community: years 1-4 after disturbance
Plant community composition and change was studied in the presence and absence of different mammalian herbivores over the first four years after a disturbance that returned the field to the seedExpand
LANDSCAPE ECOLOGY OF MAMMALS: RELATIONSHIPS BETWEEN DENSITY AND PATCH SIZE
A much discussed issue in landscape ecology is how processes that operate within spatially subdivided subpopulations scale-up to create a larger, landscape-level dynamic. A first step in answeringExpand
Use of space and habitats by the eastern Chipmunk, Tamias striatus
Regression analyses showed a significant, positive association between capture frequency of eastern chipmunks ( Tamias striatus ) and open-understory and closed-overstory habitats. Analyses withinExpand
