The ethical and welfare challenges with radio tracking animals is ensuring that the device is removed from the animal at the conclusion of the study. We tested two types of collar break-away mechanisms, designed to release the collars over time. One is Cotton Thread weak-link and a second Timed Release Device. For both break-away types, the release timing was unpredictable, and poor collar recovery rates show the importance in adding camera traps to monitor collared animals. Photograph by Leticia F. Povh.

Reptiles are vulnerable to habitat loss and fragmentation, yet the influence of landscape structure on species distributions is unknown. In this study we modelled the distributions of 40 reptile species in Victoria, Australia, and found that the cover and spatial configuration of native vegetation influence the distribution of most species. Knowledge of how landscape structure influences species’ distributions will help to improve biodiversity management in fragmented landscapes. Photograph by S. J. Mulhall.

This study aimed to test oral baits as potential vaccine-delivery vehicles for Tasmanian devils. Captive and wild devils consumed placebo versions of commercial baits used on mainland Australia. Abundant non-target species, such as brushtail possums, Tasmanian pademelons, and eastern quolls consumed most baits in the wild. Implementation of automated bait dispensers increased bait uptake by devils to over 50% at the same regional field sites. Photograph by Jennifer M. Moffat.

We analysed overlap in the habitat area and habitat suitability between giant panda (Ailuropoda melanoleuca) and sambar (Rusa unicolor) to examine potential sympatric species competition. The results indicate that the similarity of habitat requirements between the two species is high. In addition, the competition for space use among populations of the two species could intensify as the sambar population increases. Niche overlap and interspecific competition between sympatric species should be a stronger focus in endangered species conservation. We suggest strengthening the habitat restoration and establishment of corridors for all key species to alleviate the increased competition associated with niche overlap among sympatric species.

Infectious diseases such as Q-fever (Coxiella) often contribute to reproductive failure in terrestrial mammals. We investigated whether this pathogen could be detected in the environment and in Australian fur seal placentas by using molecular techniques. Our results indicated that Coxiella burnetii is present in two of the largest breeding colonies and that environmental DNA can be used to survey for infected colonies. Photograph by Hanna Geeson.

A key threat to koalas in some parts of their home range is vehicle strikes. Understanding what may encourage people to be more vigilant and drive slowly in areas with significant numbers of koalas is an important research undertaking. This paper identifies values-based segments that influence the intention to slow down significantly; and demonstrates the necessity of using segmentation to guide conservation program planning to decrease driving speed.
