Resource selection, predation risk, and population dynamics of woodland caribou
… in this region. I examined spatial patterns of resource selection by caribou, wolf predation risk, adult female caribou survival and, ultimately, population trend for 9 woodland caribou populations. Caribou avoided disturbance across all scales of resource selection, though avoidance of forestry …

A synergistic reputation-policy based trust model for Grid resource selection
… important role for supporting coordinated resource sharing and ensuring provision of quality of service. However, the existing Grid reputation-based trust management systems are considered limited as they are bounded to esoteric reputation-based trust models encompassing predefined metrics …

Resource selection, movement patterns, and survival of post-fledging grassland birds in Missouri
… ignore post-fledging requirements. I described resource selection, movement patterns, and survival of dickcissels (Spiza americana) and eastern meadowlarks (Sturnella magna) in southwestern Missouri, from 2002 to 2004 using radio telemetry. Across species at the micro-scale, there was support …

Following the Herd: Modeling Mule Deer Resource Selection in an Era of Solar Expansion
… facilities on mule deer populations. We used resource selection functions to identify priority habitat, essential resources, and landscape attributes (e.g., elevation, slope, distance to water, and vegetation cover) for mule deer. We then used the resulting model to examine the potential …

Nesting and Brood-Rearing Success and Resource Selection of Greater Sage-Grouse in Northwestern South Dakota
<p>Understanding population dynamics and resource selection is crucial in developing wildlife resource management plans, particularly for sensitive species. Greater sage-grouse (Centrocercus urophasianus) populations have declined range-wide at a rate of 2% per year from 1965 to 2003. In South …

Resource selection and abundance estimation of moose: Implications for caribou recovery in a human altered landscape
… apparent competition. We first examined habitat selection of moose in 2 regions with differing intensities of human disturbance in west-central Alberta and east-central British Columbia to assess how human disturbance affects the spatial separation of moose and caribou. We built resource …

Assessing cumulative human impacts on northern woodland caribou with traditional ecological knowledge and resource selection functions
… on the Atlin herd, we developed seasonal resource selection functions (RSF) at 2 spatial scales with data from 10 global positioning system collared caribou. We modeled habitat selection and assessed cumulative effects by estimating the zone of influence (ZOI) around several types of human …

Multiscale Resource Selection of Ruffed Grouse in the Black Hills National Forest of South Dakota and Wyoming
… BHNF. The objective or our study was to assess resource selection of ruffed grouse at multiple spatial scales in order to identify the most appropriate scale to manage for ruffed grouse as the MIS for aspen in the BHNF. During the springs of 2007 and 2008 we conducted drumming surveys throughout …

Habitat Resource Selection By Greater Sage Grouse Within Oil and Gas Development Areas in North Dakota and Montana
… follows that of sagebrush. Important mineral resources (i.e., gas, oil) are coincident with sage grouse habitats across much of the western United States. Sagebrush steppe habitats along the Cedar Creek Anticline of southeastern Montana and southwestern North Dakota exemplify important sage …

Seasonal Resource Selection, Site-Specific Brood Predictors, And Nest Characteristics Of Greater Prairie-Chicken Hens In Northwestern Minnesota
… described using three methods; habitat use and selection by brood-rearing hens, local invertebrate and vegetative predictors of brood use, and nest site characterization and success.</p> <p>By combining remotely-sensed imagery with estimated locations gathered by triangulation I was able to …

Resource Selection, Survival, and Departure of Adult Female Mallards From The Lake St. Clair Region During Autumn And Winter
… was to understand how mallards were selecting resources in the region and potential relationships of selection strategies. My objectives were to estimate resource selection of adult female mallards, in relation to perceived risk of hunting mortality, and determine if selection strategies were …

Spatial ecology of Western Ratsnakes (Pantherophis obsoletus) : implications for bird nest predation
… to evaluate their activity patterns and resource selection in study sites where they have been identified as the predominant bird nest predator. First, we used local weather data to model seasonal ratsnake movements as they relate to bird nesting phenology and climate change. Next, we …
