Arboreal mammals are some of the most sensitive to the impacts of habitat fragmentation. Such species are either reliant on continuous forest cover or canopy connectivity to facilitate movement, especially if they are obligate arboreal species. Habitat loss from agricultural expansion and urban development, threatens the ability of arboreal mammals to disperse to enable landscape scale gene flow. Over long-time periods this can lead to a reduction in effective population size, genetic viability, and ultimately the ability to persist in the face of continuing threats. Creating wildlife corridors is one landscape conservation initiative that can aid in mitigating threats. This can be achieved through the identification of pathways of existing habitat, calculated through spatial models, and coupled with the evaluation of corridor functionality. Ideally, such corridors should benefit multiple species compared to focusing on one focal species, to achieve greater biodiversity conservation ....
Context: Quantifying the space use and movement patterns of animals is important to understand other aspects of a species ecology, such as habitat use and social systems. However, basic data on space use and movement patterns, and how they are influenced by biotic or abiotic factors, are lacking for many species. Aims: We identified the space use and movement patterns of the central bearded dragon (Pogona vitticeps), and assessed how external factors (environmental conditions) and internal factors (sex and morphology) shape these patterns. Methods: We tracked 36 P. vitticeps individuals over three seasons from 2017 to 2018. Animals carried tags with a Global Positioning Systems (GPS) device to collect spatial data and an accelerometer to collect movement data in far western New South Wales, Australia. Measurements of body morphology were taken for each individual and ambient temperatures were recorded. Space use was analysed by calculating minimum convex polygons (MCPs) and kernel dens ....
The use of camera traps to track individual mammals to estimate home range and movement patterns, has not been previously applied to small mammal species. Our aim was to evaluate the use of camera trapping, using the selfie trap method, to record movements of small mammals within and between fragments of habitat. In a fragmented landscape, 164 cameras were set up across four survey areas, with cameras left to record continuously for 28 nights. Live trapping was performed prior to ear mark animals to facilitate individual identification on camera. Four small mammal species (sugar glider; Petaurus breviceps; brown antechinus; Antechinus stuartii, bush rat; Rattus fuscipes, and brown rat; Rattus norvigecus) were recorded on camera (N = 284 individuals). The maximum distance travelled by an individual sugar glider was 14.66 km, antechinus 4.24 km; bush rat 1.90 km and brown rat 1.28 km. Movements of both female and male sugar gliders in linear fragments were recorded at much higher rates t ....
