A local nearest-neighbor convex-hull construction of home ranges and utilization distributions

  author={Wayne M. Getz and Christopher C. Wilmers},
We describe a new method for estimating the area of home ranges and constructing utilization distributions (UDs) from spatial data. We compare our method with bivariate kernel and alpha-hull methods, using both randomly distributed and highly aggregated data to test the accuracy of area estimates and UD isopleth construction. The data variously contain holes, corners, and corridors linking high use areas. Our method is based on taking the union of the minimum convex polygons (MCP) associated… 

Estimating Utilization Distributions with Kernel Versus Local Convex Hull Methods

ABSTRACT Estimates of utilization distributions (UDs) are used in analyses of home-range area, habitat and resource selection, and social interactions. We simulated data from 12 parent UDs,

A Characteristic‐Hull Based Method for Home Range Estimation

This study explores the use of characteristic hull polygons (CHPs) as a new method of home range estimation using simulated animal locational data conforming to five point pattern shapes at three sample sizes to demonstrate the method has potential as a home range estimator.

LoCoH: Nonparameteric Kernel Methods for Constructing Home Ranges and Utilization Distributions

The results demonstrate that LoCoH methods are superior to parametric kernel methods in estimating areas used by animals, excluding unused areas (holes) and, generally, in constructing UDs and HRs arising from the movement of animals influenced by hard boundaries and irregular structures.

Comparison of Kernel Density and Local Convex Hull Methods for Assessing Distribution Ranges of Large Mammalian Herbivores

The local convex hull method recently developed for home range delineation to provide measures was compared with that of the widely applied parametric kernel density estimation and with the commonly used tile method and most effectively revealed meaningful gaps.

Effects of Point Pattern Shape on Home-Range Estimates

Abstract Home-range estimators are commonly tested with simulated animal locational data in the laboratory before the estimators are used in practice. Although kernel density estimation (KDE) has

A new selection criterion for statistical home range estimation

A numerical index is introduced, based on a penalization criterion, to rank the estimated home ranges and the optimization of the selection index provides in fact a way to select the smoothing parameter for the kernel home range estimator.

An IKONOS-based comparison of methods to estimate cattle home ranges in a semi-arid landscape of southern Africa

We estimated home range (HR) and core areas of cattle herds in a semi-arid rangeland in southern Africa using the fixed kernel and the local convex hull (LoCoH) methods. We also compared the HR

Identifying the variation in utilization density estimators and home ranges of elephant clans in Aceh, Sumatra, Indonesia

Movement ecology is fundamental to understanding animal home ranges or utilization distribution (UD), and is an important aspect in conservation management strategies. Over the years, there have been


A new linkage method is proposed, using nearest-neighbor distances first to exclude outlying locations and then to define a multinuclear outlier-exclusive range core (OEC) by cluster analysis, supported by data from radio-tagged Common Buzzards.

A Geographic Information System Method for Estimating Home Range Size

We developed a new technique to quantify home ranges by using coordinate-based data that were collected at small time intervals and entered into a Geographic Information System (GIS). We used this


This paper considers the problem of estimating the home-range size of an animal from locational data, which are usually collected by use of radio telemetry, with convex hull-based estimators. It is

Measurement of non-circular home range.

Differences in home-range size computed in commonly used software programs

With the advancement of radiotracking techniques, there has been a dramatic increase in the quantity and quality of locational and movement data obtained for a variety of wildlife species. Automated

Effects of sample size on kernel home range estimates

It is recommended that home range studies using kernel estimates use LSCV to determine the amount of smoothing, obtain a minimum of 30 observations per animal (but preferably >50), and report sample sizes in published results.

Analysing space use patterns by Thiessen polygon and triangulated irregular network interpolation: a non-parametric method for processing telemetric animal fixes

It is demonstrated that the Thiessen model delineated areas of intensive use more effectively in a home range than Kernel estimators, thus facilitating overlay operations with habitat information stored in the same ArcInfo GIS environment.

Bias in species range estimates from minimum convex polygons: implications for conservation and options for improved planning

Minimum convex polygons (convex hulls) are an internationally accepted, standard method for estimating species' ranges, particularly in circumstances in which presence‐only data are the only kind of

Eliminating autocorrelation reduces biological relevance of home range estimates

1. Destructive subsampling or restrictive sampling are often standard procedures to obtain independence of spatial observations in home range analyses. We examined whether home range estimators based
