Home range (95% Kernel Utilization Distributions) and use of space (Resource selection function models) for cheetahs reintroduced into a small (284 km2), arid, fenced national park was analysed.
Finally we compare the estimated utilization distributions and home ranges for two datasets derived using our line-KDE approach with those obtained using the point-KDE and Brownian Bridge (BB) approaches.
Least squares cross-validation was applied to obtain kernel smoothing parameters [35], [36] and utilization distribution models were developed for breeding and wintering with Animal Space Use [34].
Studies of wild mammals have used radio telemetry to produce a measure of how much home ranges overlap and how often the two animals in question are found utilizing the area of overlap (Utilization Distribution Overlap Index, UDOI) and used this as a proxy for observing direct contact.
Home-range estimates for male snakes averaged 17.8 ± 2.3 (based on Utilization Distributions [UD]) and 12.0 ± 1.9 ha (based on 100% Minimum Convex Polygons [MCP]), whereas home-range estimates for gravid female snakes averaged 7.1 ± 1.8 ha (based on UD) and 4.1 ± 1.1 ha (based on MCP) and were significantly different between both sexes for all home-range analyses.
First, we developed a new econometric model for dental services utilization that closely represents the data distribution and allows for differential effects of risk factors on different facets of the utilization distribution (i.e. the use of dental services and the type and amount of care received).
Covariate predictors in the poultry models included latitude (Lat), bar-headed goose utilization distribution (BHGO UD), poultry density (PD), and cropland (Crop).
We delineated core areas and calculated the utilization distribution overlap indices in R [R Core Development Team, 2012] using the code provide by Vander Wal & Rodgers [ 2012] and the package "adehabitatHR" [Calenge, 2006], respectively.
Using generalized linear models, we examined the relative importance of habitat type (differing in vegetation density), probability of encountering lion (based on utilization distribution of all individual lions in the reserve), and season in predicting group size and composition.
We calculated the kernel overlap between seabirds and fisheries using the utilization distribution overlap index [24].
