Is meadowlark habitat segregation within sympatry behaviorally mediated?
… provide a rigorous understanding of meadowlark habitat use within sympatry. At the patch scale, area-sensitivity, vegetation structure, and vegetation composition have been identified as important factors influencing habitat selection. It is also widely recognized that community assemblage is …

Causes and consequences of sexual habitat segregation in grizzly bears
I studied habitat use and population dynamics of 2 grizzly bear (Ursus arctos) populations to test 3 competing hypotheses of sexual habitat segregation (no avoidance, food competition, and sex competition) and 3competing hypotheses on the effects of adult male mortality on female reproduction …

Diet overlap and habitat segregation between redbreast sunfish and age-o smallmouth bass in the North Anna River, Virginia
… food resources measured in pools and riffle/run habitats fluctuated, but were never scarce. Bass and sunfish foraging behaviors were different, particularly in late summer. Microhabitat used by bass and sunfish was assessed by snorkeling and measuring eight variables in early and late summer. …

Factors Affecting the Distribution and Abundance of Microtus Ochrogaster and M. Pennsylvanicus in East-Central Illinois (Competition, Agonistic)
An apparent case of habitat segregation between the meadow vole (Microtus pennsylvanicus) and the prairie vole (M. ochrogaster) was investigated in east-central Illinois. Local distribution of the two species indicated a strong negative association. Multivariate analysis of variance of the …

The competitive dynamics of two Protea shrubs growing in a mixed fynbos stand
Patterns of segregation among Protea species were investigated. Interspecific competition was studied as a cause of these patterns. Two different methods were used for measuring competition in a mixed stand of P. lepidocarpodendron and P. corona/a growing on the Cape Peninsula. These were the …

Consequences of drought, flooding, and insect herbivory on the distributions of closely related willow and poplar (Salicaceae) species across hydrologic gradients in Minnesota wetlands
… mediated by water stresses likely caused habitat segregation among species. Furthermore, species in the Salicaceae family are known to host a variety of insect herbivores, which makes insect herbivory another possible process influencing beta diversity among the Salicaceae communities. …

Ecology and conservation of Formosan clouded leopard, its prey, and other sympatric carnivores in southern Taiwan
… Assessment of the prey base and available habitat indicated that prey depletion and habitat loss, plus historical pelt trade, were likely the major causes of extinction of clouded leopards in Taiwan. Using zero-inflated count models to analyze distribution and occurrence patterns of …

The Effects of Food, Cover and Competition on Demography, Dispersal and Density of Voles
… pennsylvanicus) populations that occupied habitat patches that differed in availability of high quality food and amount of vegetative cover. I tested a series of a priori hypotheses regarding the effects of habitat quality on the movement of individuals between habitats. These hypotheses …

Habitat use by wintering passerines in fire-managed forests along the U.S. Gulf Coast
<p>Coastal habitats are being impacted by land development, fragmentation, and disturbance related to climate change. The remaining natural areas need to use planned management that may, in some cases, include the use of prescribed fire to maintain habitat quality. Numerous species of passerines, …

Modeling Sex-Specific Seasonal Habitat Selection for Elk (Cervus Elaphus) in Central Washington
… exploiting a variety of environments. I studied habitat selection and sexual segregation of the Colockum elk herd in central Washington. I used a resource selection probability function (RSPF) to evaluate habitat use by males and females during summer and winter seasons. I assisted Washington …
