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 ...

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.

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.

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 ...

Logistic Methods for Resource Selection Functions and Presence-Only Species Distribution Models

Proceedings of the AAAI Conference on Artificial Intelligence, 2011
In order to better protect and conserve biodiversity, ecologists use machine learning and statistics to understand how species respond to their environment and to predict how they will respond to future climate change, habitat loss and other threats.

Medical Resource Allocation as a Function of Selected Patient Characteristics

Journal of Applied Social Psychology, 2006
This study assessed how changes in the characteristics of parental status, intelligence level, and mental health of hypothetical patients suffering from a kidney disease altered participants' decisions about allocating access to a life‐supporting artificial‐kidney machine.

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 ...
