“…It was determined that the home ranges of these crabs, during the 3-12 month period, ranged from 22,706 to 2,095,728 m 2 and that smaller crabs had the largest home ranges. In another study, Guerra-Castro et al (2007) used manual ultrasonic telemetry to estimate the home ranges of two species of swimming crabs (Arenaeus cribrarius and Callinectes ornatus). Home range estimations were based on 3-21 positions for each animal, collected over the course of 10 days.…”

“…The concentrated use in the center of a home range is a pattern commonly observed in primates and other Table 4 Results of general linear model ANCOVAs for the effects of border area characteristics (polygon size, dip (presence-absence), neighbors (presence-absence)), season (cold-dry, hot-wet, hot-very wet), and social organization (one-male-multimale) on percent use of border polygons (arcsine transformed animals (e.g., Ganey and Balda 1989;Zhang 1995;Di Bitetti 2001;Guerra-Castro et al 2007), and in this study, it could be due to the presence of important sleeping sites (see also Chapman et al 1989). This pattern closely follows Terborgh's (1983) suggestion that animals will show concentrated use of resources that occur in sparsely distributed patches.…”

An animal's use of space may be strongly influenced by habitat edges and neighboring conspecifics encountered in and around its home range. Habitat edges are known to affect species density and distribution, but their impact on home range use is largely unknown. Additionally, among large animals, interactions with neighbors become particularly important as increasing home range size leads to decreasing exclusivity of resource use, but the effect of neighbors on home range use remains poorly understood. Here, we examine the influence of neighbors and habitat edges on the ranging patterns of three groups of Phayre's leaf monkeys (Trachypithecus phayrei crepusculus) in northeast Thailand over a period of more than 2 years. The study animals occupied dry evergreen forest, and adjacent patches of dry dipterocarp forest created a habitat edge and formed barriers between some groups. We found that the use of home range interiors was 50-90% higher than the border areas, indicating concentrated use of resources within the home range. The use of peripheral areas was influenced by social organization, the presence of neighboring groups, and forest edges. While one multimale group showed no particular habitat preference, two single-male groups preferred areas bordering dry dipterocarp habitat and avoided areas bordering neighboring groups, suggesting that the threat of neighbors mediated border presence. Additionally, groups may have been attracted to the forest edge, where conspecific competitors are absent and increased sunlight may increase resource abundance and/or quality. This study revealed that the use of border areas can be modulated by neighboring groups and habitat edges, thereby adding to our understanding of home range use among territorial species in heterogeneous habitats.

“…Recently, biotelemetry in crustaceans has been complemented with geographic information systems (with software such as the Animal Movement Analyst Extension (AMAE) to ArcView) to study medium and wide scale movements of species such as C. sapidus, Callinectes ornatus Ordway, 1863, Arenaeus cribrarius (Lamarck, 1818), and Cancer magister Dana, 1852 (see Carr et al, 2004;Holsman et al, 2006;Guerra-Castro et al, 2007). On the other hand, small-scale movements have been approached with the use of automatic positioning systems (mainly using VRAP technology, from VEMCO Radio Acoustic Positioning, Vemco Ltd. Halifax, Canada), specifically in studies on H. americanus and Paralithodes camtschaticus (Tilesius, 1815) (see Golet et al, 2006;Jorgensen et al, 2007;Scopel et al, 2009;Watson et al, 2009).…”

“…To illustrate the importance of the monitoring time lapse and the number of individuals necessary for a telemetry crustacean project, several analyses using previously published data will be presented (from Guerra-Castro et al, 2007). In that article, several variables related to activity patterns and zonations of two portunid species (Callinectes ornatus and Arenaeus cribrarius) were evaluated.…”

“…It is evident how the standard errors (the bars) diminish with the increase of the monitoring time lapse and how these get closer until they approach the mean. The decrease of the standard error is a clear indicator of precision improvement (Sokal & Rohlf, 1995); a fact that should be strongly considered to understand the wide variability reported for crustacean movements (e.g., González-Gurriarán et al, 2002;Guerra-Castro et al, 2007). Certainly, high variability is not a problem from a biological or a statistical perspective if this variability is real.…”

The implementation of ultrasonic telemetry as a technique to evaluate ecological traits of marine organisms has allowed biologists to obtain information that is hard or impossible to achieve by traditional sampling methods; which in turn improves the quantification, in their natural habitats, of activity patterns, movements, migrations, habitat utilization and zonation, among other biological and physiological variables. Despite its transcendence, this technique has been scantly applied in crustacean decapod studies, mainly due to the high costs involved (resources, time, and personnel) and the problem of how to analyze quantitatively telemetry data to test hypotheses. Thus, the aim of this article is to evaluate, discuss, and review the statistical methods employed in this discipline and make some recommendations concerning the sampling effort and efficiency, as well as to suggest appropriate ways to analyze data, specifically with frequentist statistics (parametric and nonparametric). Examples are given based on data previously published.
