We studied the home ranges and seasonal movements of 20 wood turtles (Clemmys insculpta) living near the northern limit of their distribution in the Mauricie region, Quebec, Canada. We found average home-range areas of 28.3 ha. Wood turtles showed site fidelity; there was an average overlap of 60.7% in their home ranges, and 88.8% of the home-range centroids were not significantly different for the 2 years of the study. The home ranges were larger than those reported from studies in more southerly locations, leading us to hypothesize larger home-range territories with increasing latitude. Our analyses indicate that turtle movements could be grouped into four distinct activity periods during the active season: the prenesting, nesting, postnesting, and prehibernation periods. We found that wood turtles were closely associated with streams. Based on the importance of this habitat for the species, we suggest the establishment of protected buffer strips along streams used by wood turtles.

We characterized the chronology of habitat use by the wood turtle, Clemmys insculpta (LeC., 1829), in the Mauricie region of Quebec, Canada. We also determined if this species used habitats according to availability within a home range and identified habitat features influencing habitat selection. Habitats were characterized for 20 wood turtles followed weekly by telemetry during the active season of 1997. Turtles used a great diversity of terrestrial and aquatic habitats. Alder (Alnus rugosa (Du Roi) Spreng.) stands were the most used terrestrial habitats throughout the active season. Habitat use varied according to activity period. Indeed, wood turtles used aquatic habitats and alder stands during prenesting and prehibernation activity periods, whereas all habitat types were used during nesting and postnesting activity periods. Wood turtles did not use habitats randomly within their home ranges, suggesting that they selected them. Wood turtles seemed to select mixed forest stands that were relatively young (16 years), short (1–4 m), had low arborescent cover (25%), moderate cover of the upper shrub layer (35%), and low total canopy closure (0%–50%). This knowledge will be helpful in the establishment of future conservation measures.

Abstract In previous experiments, Dark-eyed Juncos (Junco hyemalis) were captured on a winter home range to which they had shown year-to-year site fidelity and held there until just before the autumn. They failed to show normal autumn migratory restlessness and fattening, which suggested that previous experience at the migratory destination suppressed readiness to migrate. We asked what the suppressing cues might be. Possibilities included very local features peculiar to the individual's winter home range (e.g. its trees) and cues common to the general region (e.g. geophysical or celestial information); features of the latter sort might give information about latitude. To test these possibilities we monitored autumn restlessness and fattening of new groups of juncos that were held before migration where some could perceive landmarks of their familiar winter home range and others only more general information about their location. In autumn those held at, near, and far south of their winter home ranges again failed to become restless or fat. A small group held far north of their winter home ranges became somewhat restless, significantly more so than the others. These may have perceived that they had not reached their usual winter latitude, but alternative explanations are possible.

Abstract Background: The movement ecology of mutton snapper Lutjanus analis is poorly understood despite their ecological and economic importance in the Caribbean. Passive acoustic telemetry was used to determine home ranges of six adult L. analis, including diel patterns, in Brewers Bay, St. Thomas, US Virgin Islands. Understanding long-term space use, including site fidelity and habitat usage, is necessary to implement effective and appropriate management actions for a species with extensive space and resource needs.Results: Individual L. analis were tracked over an average period of 316 days (range 125 - 509 days) and showed high site fidelity to relatively small home ranges (mean ± SD: 0.103 ± 0.028 km2, range 0.019 - 0.190 km2) and core use areas with low overlap among individuals. Most home ranges had a habitat composition dominated by seagrass and to a lesser degree, coral reef and/or pavement. Nighttime activity spaces were distinct from but contained within daytime areas.Conclusions: Mutton snapper showed strong site fidelity to home ranges in Brewers Bay. Two individuals that were absent from the array for more than a few hours were detected at separate arrays at spawning aggregation sites. This study expands upon knowledge of mutton snapper home range characteristics, highlights the importance of maintaining adjacent high-quality habitat types in any spatial management plan, and encourages the adoption of other types of management strategies, particularly for transient-aggregating species.

Abstract The giant armadillo (Priodontes maximus) is the largest living armadillo. This naturally rare and poorly known species is endemic to South America and classified as “Vulnerable” by the IUCN. Here we explored aspects of the spatial ecology of P. maximus in Midwestern Brazil to gain insights on its ecology and biology to support conservation efforts. In 8 years, we identified 50 individuals of P. maximus and monitored 23 of them using telemetry methods. To characterize site fidelity and home range, we fitted individual continuous-time movement models and estimated Autocorrelated Kernel Density Estimates. We built a Structural Equation Model to evaluate how home-range area and daily displacement are related to each other, to sampling effort, and to individual characteristics. We estimated home-range overlap between pairs of different sexes using a bias-corrected Bhattacharyya coefficient. Finally, we formulated a canonical density estimation formula to characterize minimum population density. We gathered a total of 12,168 locations of P. maximus. The best-fitted movement models indicated site fidelity for all individuals and a median adult home-range area of 2,518 ha. Median adult daily displacement was 1,651 m. Home-range area scales positively with daily displacement and daily displacement scales positively with body mass. Median home-range overlap between pairs was low (4%) and adult females presented exclusive home ranges among themselves. Median minimum density was 7.65 individuals per 100 km2 (CI = 5.68–10.19 ind/100 km2). Our results are congruent with characterizing P. maximus as a generally asocial species, most likely promiscuous/polygynous, that establishes large, long-term home ranges, which grants the population a naturally low density. Spatial patterns and biological characteristics obtained in this study can be used to guide future conservation strategies for P. maximus in the Pantanal wetlands and elsewhere.

Species Ecology

In 2008, after 9 years of presumed local extinction, brush-tailed rock-wallabies (Petrogale penicillata) were reintroduced at Moora Moora Creek in the Grampians National Park, western Victoria. Since little is known about this species in Victoria, the reintroduction presented an important opportunity to gain information on the species’ ecology. Radio-tracking was undertaken and home range determined for three individuals released 11 months before this study and a further five individuals that were released at the commencement of the study in October 2009. Home-range size showed little variation amongst individuals, with a mean overall home range of 26 ha (±1.69, s.e.) and a mean core home range of 2.5 ha (±0.24, s.e.). Newly reintroduced individuals showed higher levels of association with wallabies from the same release and greater site fidelity when known conspecifics were close. Within 5 months of release, newly reintroduced animals showed home ranges similar in both size and distribution to those of animals released 11 months prior.

Social Patterns

Sixteen stone martens (Martes foina) were intensively radio-tracked in central Italy in order to assess their spacing patterns. Home-range sizes and distances travelled per night were analysed with respect to sex, age, season, and habitat. Intrasexual territoriality is confirmed for the species; home-range edges appeared to be determined by the dispersion of neighbours' territories. Home-range size was positively correlated with the presence of woodland (less abundant and more dispersed resources). Males travelled longer distances than females, although home-range sizes did not differ significantly by sex; males did not move more during the rutting season than in other seasons. Subadults were tolerated by adults for varying periods, then in some cases they started an exploring phase before settling into a vacant territory. Stone martens' spacing patterns were affected by sex, age, social interactions, and resources. In particular, social patterns appear to be a key influencing factor, as territoriality, parental behaviour, mating interactions, and dispersal of young can account for site fidelity, dispersion of home ranges, and distance travelled. In particular, our data indicate the importance of the extended relationship between the mating pair, which is probably related to male parental investment, in determining the spacing patterns of the species.

Initial Description

I used radio-telemetry to track the movements of Mangrove Cuckoos (Coccyzus minor) captured in southwest Florida. Relatively little is known about the natural history of Mangrove Cuckoos, and my goal was to provide an initial description of how individuals use space, with a focus on the size and placement of home ranges. I captured and affixed VHF radio-transmitters to 32 individuals between 2012 and 2015, and obtained a sufficient number of relocations from 16 of them to estimate home-range boundaries and describe patterns of movement. Home-range area varied widely among individuals, but in general was roughly four times larger than expected based on the body size of Mangrove Cuckoos. The median core area (50% isopleth) of a home range was 42 ha (range: 9–91 ha), and the median overall home range (90% isopleth) was 128 ha (range: 28–319 ha). The median distance between estimated locations recorded on subsequent days was 298 m (95% CI [187 m–409 m]), but variation within and among individuals was substantial, and it was not uncommon to relocate individuals >1 km from their location on the previous day. Site fidelity by individual birds was low; although Mangrove Cuckoos were present year-round within the study area, I did not observe any individuals that remained on a single home range throughout the year. Although individual birds showed no evidence of avoiding anthropogenic edges, they did not incorporate developed areas into their daily movements and home ranges consisted almost entirely of mangrove forest. The persistence of the species in the study area depended on a network of conserved lands–mostly public, but some privately conserved land as well–because large patches of mangrove forest did not occur on tracts left unprotected from development.
