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

Transcending scale dependence in identifying habitat with resource selection functions

Ecological Applications, 2012
Multi‐scale resource selection modeling is used to identify factors that limit species distributions across scales of space and time. This multi‐scale nature of habitat suitability complicates the translation of inferences to single, spatial depictions of habitat required for conservation of species.

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.

WEIGHTED DISTRIBUTIONS AND ESTIMATION OF RESOURCE SELECTION PROBABILITY FUNCTIONS

Ecology, 2006
Understanding how organisms selectively use resources is essential for designing wildlife management strategies. The probability that an individual uses a given resource, as characterized by environmental factors, can be quantified in terms of the resource selection probability function (RSPF).

Relating populations to habitats using resource selection functions

Trends in Ecology & Evolution, 1999
Habitat use can be characterized by resource selection functions (RSFs) that are proportional to the probability of an area being used by an animal. We highlight two procedures that have recently been used to relate RSFs to population density, dependent upon which field procedures are practical for a species.

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.

Modal functioning of rhetorical resources in selected multimodal cartoons

Semiotica, 2019
AbstractFirstly, this paper aims to analyze how verbal and visual modes contribute to build two basic components of cartoons: the referenced situation and the fictional situation. Secondly, it aims to unravel the semiotics of this discursive genre by offering a fine-grained picture of modal variations and continuities of the rhetorical resources ...

Process-focussed, multi-grain resource selection functions

Ecological Modelling, 2015
a b s t r a c t Like most aspects of ecology, the process of habitat or resource selection scales in space as well as time. However, scaling questions have generally focused on extent including size of study area and home ranges that dictate availability of resources.

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 ...

Examples of the use of resource selection functions

1993
This chapter provides an overview of the use of resource selection probability functions for studying resource selection. Examples are presented to illustrate (a) the commonly occurring case where resources are considered to be in several categories, (b) the difference between census and sample data, and (c) the difference between studies that involve ...
