Distribution, Movement, Habitat Usage, Food Habits, and Associated Behavior of Reintroduced Elk in Theodore Roosevelt National Park

Management of Roosevelt Elk Habitat and Harvest

Vegetation changes associated with a population irruption by Roosevelt elk

Interactions between large herbivores and their food supply are central to the study of population dynamics. We assessed temporal and spatial patterns in meadow plant biomass over a 23-year period for meadow complexes that were spatially linked to three distinct populations of Roosevelt elk (Cervus elaphus roosevelti) in northwestern California. Our objectives were to determine whether the plan...

State–space Models Link Elk Movement Patterns to Landscape Characteristics in Yellowstone National Park

Explaining and predicting animal movement in heterogeneous landscapes remains challenging. This is in part because movement paths often include a series of short, localized displacements separated by longer-distance forays. This multiphasic movement behavior reflects the complex response of an animal to present environmental conditions and to its internal behavioral state. This state is an auto...

Male group size, female distribution and changes in sexual segregation by Roosevelt elk

Sexual segregation, or the differential use of space by males and females, is hypothesized to be a function of body size dimorphism. Sexual segregation can also manifest at small (social segregation) and large (habitat segregation) spatial scales for a variety of reasons. Furthermore, the connection between small- and large-scale sexual segregation has rarely been addressed. We studied a popula...

Habitat association and distribution of rodents and insectivores in Chebera Churchura National Park, Ethiopia

The main objective of the study was to characterize the habitat composition and distribution of rodents and insectivores in a recently established Chebera Churchura National Park, Ethiopia. The study was carried out between 2010 and 2011. Study grids were marked in seven randomly selected habitats. Swampy forest, riverine forest, grassland, wooded grassland, bushland, lake shore, and agricultur...
