A New Method for Estimation of Resource Selection Probability Function

Journal of Wildlife Management, 2009
ABSTRACT  Weighted distributions can be used to fit various forms of resource selection probability functions (RSPF) under the use‐versus‐available study design (Lele and Keim 2006). Although valid, the numerical maximization procedure used by Lele and Keim (2006) is unstable because of the inherent roughness of

Accounting for animal movement in estimation of resource selection functions: sampling and data analysis

Ecology, 2009
Patterns of resource selection by animal populations emerge as a result of the behavior of many individuals. Statistical models that describe these population‐level patterns of habitat use can miss important interactions between individual animals and characteristics of their local environment; however, identifying these interactions is difficult.

Three way k-fold cross-validation of resource selection functions

Ecological Modelling, 2008
Abstract A resource selection function (RSF) yields a prediction that is proportional to the probability of use of a resource unit by an organism. Because many apparently adequate models fail in new areas or time periods we developed a method for model selection and evaluation based on the model’s ability to predict generally, spatially, and ...

Integrated step selection analysis: bridging the gap between resource selection and animal movement

Methods in Ecology and Evolution, 2016
1. A resource selection function is a model of the likelihood that an available spatial unit will be used by an animal, given its resource value. But how do we appropriately define availability?

Considering ecological dynamics in resource selection functions

Journal of Animal Ecology, 2009
Summary 1. Describing distribution and abundance is requisite to exploring interactions between organisms and their environment. Recently, the resource selection function (RSF) has emerged to replace many of the statistical procedures used to quantify resource selection by animals. 2.
