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).

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 ...

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 ...

Estimating encounter‐habitat relationships with scale‐integrated resource selection functions

Journal of Animal Ecology
Abstract Encounters between animals occur when animals are close in space and time. Encounters are important in many ecological processes including sociality, predation and disease transmission. Despite this, there is little theory regarding the spatial distribution of encounters and no formal framework to relate environmental characteristics to ...

Using Resource Selection Functions to Improve Estimation of Elk Population Numbers

The Journal of Wildlife Management, 2008
Abstract: Stratification is commonly used to improve sampling efficiency of aerial surveys of ungulate populations with strata typically based on a priori information, such as preflight animal observations or vegetation attributes as surrogates for animal densities.

Estimating a resource selection function from two samples of resource units using logistic regression and discriminant function methods

1993
When a study of resource selection involves the collection of only two samples it is possible to simplify the estimation of a resource selection probability function. In particular, under certain conditions the estimation can be carried out using logistic regression or discriminant function analysis.

Resource Selection Functions for Wood Stork Foraging Habitat in the Southern Everglades

Waterbirds, 2011
Abstract. Modeling habitat selection of species with specific foraging requirements is an effective means to evaluate landscape quality for restoration and conservation purposes. Proportional hazards regression, a discrete choice model, was used to develop resource selection functions for breeding Wood Stork in the southern Everglades during the 2006 ...

A New Method for Estimation of Resource Selection Probability Function

The 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

Selection of floral resources to optimise conservation of agriculturally-functional insect groups

Journal of Insect Conservation, 2012
Non-crop vegetation in agricultural landscapes can provide a means of conserving insects in farmed landscapes and optimising on-farm ecosystem services as a result. Inclusion of floral resources may be particularly useful in conserving many beneficial insects, where groups including pollinators and pest natural enemies often rely on nectar and pollen ...
