Graphical Abstract Image

Thermal imaging technology shows promise for improving detection rates of cryptic rainforest mammals. We found significantly more individuals of six species of nocturnal, arboreal mammals in the Australian Wet Tropics using a thermal imaging device than by spotlighting. We recommend thermal imaging be adopted as a main survey methodology for arboreal mammals in rainforest environments. Photograph by Avril Underwood.

WR21047Behaviour of a large ungulate reflects temporal patterns of predation risk

Kevyn H. Wiskirchen 0000-0002-2759-2590, Todd C. Jacobsen, Stephen S. Ditchkoff, Steve Demarais and Robert A. Gitzen
pp. 500-512
Graphical Abstract Image

Prey response to temporal changes in predation risk is foundational to predator–prey dynamics and important when managing game populations. We examined white-tailed deer response to temporal patterns of recreational hunting in Alabama, USA. Deer altered movements during high-risk periods, although population-level responses were detected only when accounting for temporal scale of risk fluctuation. Our results demonstrated the awareness of a large ungulate to variation in predatory threats, and the need to consider temporal scale of risk fluctuation in future studies. Photograph by Kevyn H.

WR21102Citizen science and community action provide insights on a threatened species: nest box use by the brush-tailed phascogale (Phascogale tapoatafa)

Jessica A. Lawton 0000-0001-5871-934X, Greg J. Holland, Chris Timewell, Asha Bannon, Elizabeth Mellick and Andrew F. Bennett
pp. 513-528
Graphical Abstract Image

Conservation actions and habitat restoration frequently depend on the motivation of community groups, often stimulated by ‘flagship’ species of concern. In south-eastern Australia, the installation of nest boxes to support hollow-dependent wildlife is a common activity of such groups. Analysis of monitoring data collected by a community group on nest box use by a threatened marsupial provides insights into the ecology of this species, and into the strengths and limitations of community-based, citizen science monitoring.

Graphical Abstract Image

A density estimate derived from camera trapping and spatially explicit capture recapture (SECR) modelling was produced for the first time for the numbat, a small cryptic mammal with individually distinct coat patterns. This has resulted in better population estimates. With refinements, this could form the basis of a standardised approach to assessing and monitoring numbat populations and their responses to translocations, threats and management, leading to better biodiversity conservation outcomes.

WR21060Grizzly bear response to translocation into a novel environment

Gordon B. Stenhouse 0000-0001-9907-4912, Terrence A. Larsen, Cameron J. R. McClelland, Abbey E. Wilson, Karen Graham, Dan Wismer, Paul Frame and Isobel Phoebus
pp. 540-556
Graphical Abstract Image

To mitigate conservation conflict, large carnivores are often translocated into novel environments, and are not typically monitored afterwards. We investigated the impacts of translocation by comparing translocated and resident grizzly bears, and found differences in exploration behaviour, habitat use, and response to human-caused mortality risk. Managers and the public should recognise that translocated bears require both time and space to adapt to their new environment. Photograph by Mark Bradley.

WR20152Space use and daily movement patterns in an arid zone agamid lizard

Adam Bernich 0000-0002-6121-0015, Kimberly Maute, Isabella C. Contador-Kelsall, Paul G. Story, Grant C. Hose and Kristine French
pp. 557-570
Graphical Abstract Image

Data on the space use and movement patterns of a species are important, but are lacking for many species. Here we tracked central bearded dragons (Pogona vitticeps) across different seasons to describe their space use and movement patterns, and to investigate what influences these patterns. Movement patterns were, as expected, driven by temperature, but unlike related species, there were a high proportion of individuals roaming over large areas. Photograph by Adam Bernich.

Graphical Abstract Image

The southern bent-wing bat is a critically endangered insectivorous miniopterid bat, the diet of which has never been described. Our study used metabarcoding of arthropod DNA in bat scats and guano to show the species feeds predominately on moths, many of which are agricultural pest species. Our research provides crucial diet knowledge and a framework for further study of insectivorous bat diets. Photograph by Steve Bourne.
