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 …

Summer Habitat Selection of Mountain Goats (Oreamnos americanus) in the Interior Wetbelt of the Northern Columbia Mountains, British Columbia, Canada
… species can differ in behavioral and habitat selection patterns in response to distinct precipitation regimes and geophysical environments. We analyzed the relationship between GPS radio-collar locations and landscape variables to derive probabilistic resource selection functions to identify …

Effects of Large-Scale Gold Mining on Habitat Use and Selection by a Resident Population of American Pronghorn
… disturbances, including extraction of natural resources, are reducing and fragmenting habitat for wildlife across the western United States. The effects of these disturbances on wildlife populations have been explored by studying populations that migrate through oil and gas fields or wind and …

Fantastic Birds and Where to Find Them
… to improve habitat variables used in nest-site selection modeling for Mojave Desert riparian songbirds, including the endangered Least Bell's Vireo (Vireo bellii pusillus). I compared UAS and satellite image products of vegetation structure within first and second order resource selection …

Behavioural Ecology in Conservation Planning: Individual and Sex-Specific Insights from Woodland Caribou (Rangifer tarandus caribou) in Western Canada
… evaluated how variation in movement and habitat selection patterns may reveal ecologically meaningful differences. Analysis of 24 different movement behaviours for female caribou, including migration tendency, home range shape and size, and calving strategies, identified six broad behavioural …

Ranging patterns and resource use in samango monkeys
… is largely determined by the availability of resources and the risk of predation both across time and space and is highly scale-dependent. The aim of this study was to investigate the factors that influence space use at the species level using resource selection functions, at the group level …

Habitat Selection and Resource Use by Bighorn Sheep Following Translocation
… Understanding how translocated ungulates select resources and adapt to new habitats is critical for improving long-term outcomes of conservation. Few ungulates epitomize the challenges of reintroduction by translocation than bighorn sheep (Ovis canadensis). Bighorn sheep were once extirpated …

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 …

Short-term effects of wildfire on Sierra Nevada bighorn sheep habitat ecology
We studied changes in vegetation and habitat selection by endangered Sierra Nevada bighorn sheep (Ovis candensis sierrae; hereafter Sierra bighorn) for 2 years following wildfire on winter ranges in eastern California. We hypothesized that wildfire would change both forage availability and …

HUMAN PREDATION RISK AND ELK BEHAVIOR IN HETEROGENEOUS LANDSCAPES

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 …

Hierarchical summer habitat selection by the North American porcupine in western Montana
… to quantify home range and hierarchical habitat selection at the second, third, and fourth order, while noting both mortality and reproductive rates. Second and third order habitat selection was analyzed by estimating resource selection functions using multiple logistic regression with a logit …

Integrative perspectives of wild and captive sifaka conservation

How a Central-Place Forager (Callospermophilus lateralis) Modifies its Movement Behavior to Navigate a Risky Landscape and Maximize Fitness
… conflicting behaviors can affect differential selection of food patches and how much time individuals may spend foraging in safe versus risky patch types. Golden-mantled ground squirrels (Callospermophilus lateralis) are granivorous rodents that are widespread throughout mountainous regions of …

Camera traps as sensor networks for space-time exploration of terrestrial mammal communities
… along a ruggedness gradient was studied. Using resource selection functions and multivariate statistics, this chapter showed that the strength of affinities, which mammals developed with specific terrain roughness, varied among species. It also enabled the recognition of subtle and continuous …
