PC17001Ecological consequences of land clearing and policy reform in Queensland

Land clearing has increased in Queensland since a shift in policy in 2013, threatening biodiversity, impairing the functioning of terrestrial, freshwater, and marine ecosystems (particularly the Great Barrier Reef), and contributing to climate change. We review these impacts, provide an overview of the policy background, and suggest options for policy reform.

Behavioural ecology increasingly contributes to effective species conservation. This review presents our current knowledge of behavioural aspects of the Lumholtz’s tree-kangaroo (Dendrolagus lumholtzi) in relation to various conservation issues. Conclusions are drawn in regards to habitat conservation, management of fragmented landscapes, responses of the species to introduced predators, and the rehabilitation of orphaned juvenile tree-kangaroos.

PC17006Reduced efficacy of baiting programs for invasive species: some mechanisms and management implications

pp. 240-257

‘Bait-resistance’ – progressive decrease in bait efficacy over time – can develop due to changes in behaviour of the target pest species (innate and learned bait-avoidance behaviour) and increased physiological toxin-tolerance. Both are more likely to develop when animals are exposed to sublethal baits. We explore the possibility of bait resistance in the red fox (Vulpes vulpes), an introduced predator in Australia.

PC17008The remaining koalas (Phascolarctos cinereus) of the Pilliga forests, north-west New South Wales: refugial persistence or a population on the road to extinction?

pp. 277-294

We investigated the decline of koalas in the Pilliga forests using repeat surveys undertaken between 1990 and 2014. Koalas had declined and were found in only 21% of sites in which they were initially observed. Declines occurred evenly across the Pilliga, with persistence at a site seemingly related to a high initial density of koalas rather than to a slower rate of decline.

PC17005Preliminary observations of dingo responses to assumed aversive stimuli

Rob Appleby, Bradley Smith, Jess Mackie, Lilia Bernede and Darryl Jones
pp. 295-301

A pilot assessment of the responses of a social group of dingoes on Fraser Island to hand-held stimuli presumed to be aversive was conducted. Results suggest that the efficacy of a water pistol stimulus as a repellent, possibly enhanced with a mild irritant, warrants further investigation.
