Relationship of Ruffed Grouse Home Range Size and Movement to Landscape Characteristics in Southwestern Virginia
… on ruffed grouse (Bonasa umbellus) home range size and movement, and examined grouse selection for specific landscape characteristics and cover types. Grouse home ranges and movement patterns derived from telemetry data gathered from fall 1996 through fall 1998 were overlaid onto a …

The Tortoise and the Landscape: Examining the Habitat, Daily Movement, Home Range Size, and Thermal Ecology of the Texas Tortoise (Gopherus berlandieri)
… berlandieri). Within its limited geographic range in southern Texas and northern Mexico, G. berlandieri occurs across a variety of environments (i.e., vegetation types) and environmental gradients, but prior research has been unable to identify a set of precise habitat requirements. Despite …

Movements and home range size of bald eagles from Glacier Bay National Park and Preserve, Alaska: with an analysis of satellite telemetry
During 1991-1993, I studied movements of 23 adult and 7, 8-10 week old nestling bald eagles captured in Glacier Bay National Park and Preserve, Alaska. I estimated locations by homing and satellite telemetry. During the breeding season, the distances adult eagles moved from successful, …

Effects of Testosterone on the Spatial Ecology, Coloration, and Brain Regions in Western Fence Lizards, Sceloporus occidentalis
… such as food, mates, and escape from predators. Home range size, or the total area an organism inhabits, varies in relation to numerous factors including seasonality. During the breeding season, home range size increases in males across taxa. In addition, males usually also have larger home range …

Spatial ecology of the smooth softshell turtle (Apalone mutica) in the Kaskaskia River of Illinois
… knowledge of space use including movement rates, home range size, and habitat preference. Spatial ecological information is lacking for many river turtles including the Smooth Softshell Turtle (Apalone mutica), a species inhabiting the Midwestern United States. I investigated the spatial ecology …

Home range and movement of the eastern box turtle (Terrapene carolina) in East Central Illinois
… needs. Radio-telemetry was used to study the home range size, movement, habitat use, and nesting of Terrapene carolina. Minimum Convex Polygons (MCP) and Kernel Density Estimates at 95, 75, and 50% were used to measure home range size. Mean home range size was 7.4 ha (MCP) and 5.3 ha (95% …

Assessing Habitat Quality for the Endangered Red-cockaded Woodpcker
… the relationships between fitness, habitat use, home range size, and habitat characteristics described in the guidelines. I assumed that habitat characteristics that confer quality were related to higher fitness, greater habitat use, and reduced home range size. To a large extent, the guidelines …

The spatial ecology of the Eastern box turtle (Terrapene carolina carolina) in a fragmented landscape in Southeast Tennessee, Hamilton County
The landscape throughout the range of the Eastern Box turtle (Terrapene carolina carolina) has been altered significantly since the late 1880s by habitat fragmentation. In this study, the spatial ecology and seasonal movement patterns of the Eastern Box turtle in contrasting habitat types are …

Spatial Ecology of the Spotted Salamander <em>Ambystoma maculatum</em> During the Nonbreeding Season.
… spatial distribution patterns over 2 years. The home range size of 10 Spotted Salamanders was calculated using the revised minimum area method. A clumped distribution was found at larger spatial scales, except in the first year of the study. Home range size was shown to be limited and highly …

Seasonal Movements, Habitat Use Patterns and the Effects of Human Disturbances on Elk in Custer State Park, South Dakota
… sub-herds and five bull sub-herds. Annual home ranges of these herds overlapped a mean of 18% (Range = 9-29%, SE = 3.2, n = 5) for cows and 27% (Range = 11-42%, SE = 5.8, n = 6) for bulls. Home range sizes of CSP elk varied with method of analysis, season, and sex. Mean 95% harmonic mean …

The Spatial Ecology of Wild Pigs (Sus scrofa) in Southwest Florida
… invasive species, and mitigating farther range expansion will require a thorough understanding of movement behavior, diel activity patterns, space use, and resource selection. Currently, limited empirical evidence is available on the ecology of wild pigs in Southwest Florida. Therefore, I …

Ocelot Density and Home Range in Belize, Central America: Camera-Trapping and Radio Telemetry
… declines in population abundance across their range. In recent decades protection measures (e.g. CITES) and decreased public demand for ocelot fur resulted in declines in hunting pressure. Do to their elusive nature there is little known about ocelot population size, structure or general …

The movement and landscape use of Blue Cranes in the Western Cape
… spatial-temporal information, I estimated the home range size, daily flight distances, and distance travelled throughout the day of breeding and non-breeding cranes to determine whether the breeding status/season influences their ranging behaviour. There was no significant difference of the …

An intensive study of movement and population dynamics in Triakis megalopterus in the De Hoop Marine Protected Area, South Africa
… effect, estimating natural mortality rates and home range size is vital. Triakis megalopterus, a commonly caught, endemic coastal shark of South Africa provides an excellent opportunity for this assessment. Mark-recapture data of 924 T. megalopterus caught at two sites in the De Hoop MPA from …

The Ontogeny of Spatial Ecology and Habitat Use in a Population of Cottonmouths (Agkistrodon Piscivorus) in Southwest Missouri
… summer and fall of 2008 to determine how their home ranges, rates and magnitudes of movement, and microhabitat use compared to adults previously tracked at the same site. When gravid females were excluded from the analysis, there was a strong positive effect of body size on home range size of …

Home range and activity in a Virginia population of Sceloporus undulatus
… in Virginia, was designed to determine whether home range size, home range overlap, and patterns of behavior reflected the requirements of polygyny. The lizards were seen most often on the piles of debris that characterized the study site. Home range size was most strongly influenced by the …
