Bootstrap estimation of resource selection probability functions [PDF]

Computational Ecology and Software, 2013
Resource selection functions (RSFs) are used for quantify how animals are selective in the use of the habitat period or food. A Resource Selection Probability Function (RSPF) can be estimated if N, the total number of units in the population, and n1 the ...

Huckleberry Habitat and Its Influence on Two Small Populations of Grizzly Bears (Ursus arctos) [PDF]

Ecology and Evolution
Huckleberries (Vaccinium spp.) are a nutritionally important food to grizzly bears (Ursus arctos) in interior, western North America. They provide sugar‐rich calories in late summer and fall prior to denning. We developed a resource selection function of

Habitat Selection and Specialisation of Herring Gulls During the Non-breeding Season

Frontiers in Marine Science, 2022
Understanding both the distribution and habitat use of populations through the annual cycle is vital to understanding how vulnerable species are to environmental change.

Reconciling resource utilization and resource selection functions [PDF]

Journal of Animal Ecology, 2013
Summary Analyses based on utilization distributions (UDs) have been ubiquitous in animal space use studies, largely because they are computationally straightforward and relatively easy to employ. Conventional applications of resource utilization functions (RUFs) suggest that estimates of UDs can be used as response variables in a regression involving

Evaluating resource selection functions [PDF]

Ecological Modelling, 2002
A resource selection function (RSF) is any model that yields values proportional to the probability of use of a resource unit. RSF models often are fitted using generalized linear models (GLMs) although a variety of statistical models might be used. Information criteria such as the Akaike Information Criteria (AIC) or Bayesian Information Criteria (BIC)

Solving the sample size problem for resource selection functions [PDF]

Methods in Ecology and Evolution, 2021
Abstract Sample size sufficiency is a critical consideration for estimating resource selection functions (RSFs) from GPS‐based animal telemetry. Cited thresholds for sufficiency include a number of captured animals

Identifying Potential Conservation Corridors Along the Mongolia-Russia Border Using Resource Selection Functions: A Case Study on Argali Sheep [PDF]

Mongolian Journal of Biological Sciences, 2013
The disruption of animal movements is known to affect wildlife populations, particularly large bodied, free-ranging mammals that require large geographic ranges to survive.

Territorial landscapes: incorporating density-dependence into wolf habitat selection studies [PDF]

Royal Society Open Science, 2019
Habitat selection is a process that spans space, time and individual life histories. Ecological analyses of animal distributions and preferences are most accurate when they account for inherent dynamics of the habitat selection process.

Seasonal Habitat Selection by American White Pelicans

Diversity, 2022
Resource utilization strategies of avian migrants are a major concern for conservation and management. Understanding seasonal habitat selection by migratory birds helps us explain the ongoing continental declines of migratory bird populations.

Modeling broad‐scale patterns of elk summer resource selection in Montana using regional and population‐specific models

Ecosphere, 2022
Understanding animal distribution is important for management of populations and their habitats. Across the western United States, elk (Cervus canadensis) provide important ecological, cultural, and economic benefits and the sound management of their ...
