“…Dogs and foxes, like dingoes, are canids. Previous research [41,42] has shown that some native wildlife recognize domestic dogs as predators, possibly because of prey having thousands of years of experience with the very closely related dingo. While foxes are more distantly related to dingoes than are domestic dogs, it is also possible that native prey would generalize antipredator behaviour for dingoes towards foxes, if membership of the Canidae is an appropriate proxy for a predator archetype [1].…”

Australian native mammals recognize and respond to alien predators: a meta-analysis

Prey naiveté is a failure to recognize novel predators and thought to cause exaggerated impacts of alien predators on native wildlife. Yet there is equivocal evidence in the literature for native prey naiveté towards aliens. To address this, we conducted a meta-analysis of Australian mammal responses to native and alien predators. Australia has the world's worst record of extinction and declines of native mammals, largely owing to two alien predators introduced more than 150 years ago: the feral cat, , and European red fox, Analysis of 94 responses to predator cues shows that Australian mammals consistently recognize alien foxes as a predation threat, possibly because of thousands of years of experience with another canid predator, the dingo, We also found recognition responses towards cats; however, in four of the seven studies available, these responses were of risk-taking behaviour rather than antipredator behaviour. Our results suggest that a simple failure to recognize alien predators is not behind the ongoing exaggerated impacts of alien predators in Australia. Instead, our results highlight an urgent need to better understand the appropriateness of antipredator responses in prey towards alien predators in order to understand native prey vulnerability.

“…The role of volatiles‐producing bacteria in different ecological scenarios is well known. Recently, the importance of volatiles produced by symbiotic bacteria have been stressed in scenarios of social communication (Theis et al , Ezenwa and Williams , Leclaire et al ), predator–prey, or parasite–host interactions (Bucher , Gow et al , Schulte et al ). Prey might for instance use predator odours in antipredator behaviour (Heise‐Pavlov ), or predators might use volatiles from symbiotic bacteria of prey as clues to detect their victims (Fogarty et al , Mihailova et al ).…”

Nestlings of most avian species produce faecal sacs, which facilitate the removal of nestlings’ excrements by parents, thereby reducing proliferation of potentially pathogenic microorganisms and/or detectability by predators and parasites. The nest microbial environment that birds experience during early life might also affect their development and thus, faecal sacs facilitating parental removal may be a strategy to decrease bacterial contamination of nests that could harm developing nestlings. Here, we tested this hypothesis by experimentally broken faecal sacs and spreading them in nests of spotless starlings Sturnus unicolor, thereby avoiding their removal by adults. In accordance with the hypothesis, experimental nests harboured higher bacterial density than control nests. Nestlings in experimental nests were of smaller size (tarsus length) and experienced lower probability of survival (predation) than those in control nests. Moreover, nestlings in experimental nests tended to suffer more from ectoparasites than those in control nests. We discuss the possible pivotal role of bacteria producing chemical volatiles that ectoparasites and predators might use to find avian nests, and that could explain our experimental results in starlings.

“…Additionally, both individuals spent a proportion of time engaging in 'vigilance' behaviour. Although Goodfellow's tree kangaroos do not encounter many predators of a similar body size in their native Papua New Guinea, both arboreal and terrestrial predators, including humans, still pose a risk [7]. Studies on Lumholtz's tree kanagroos (D. lumholtzi) highlighted an increase in vigilance behaviour when exposed to odour cues from predatory species [7].…”

“…Behavioural research has revealed that many species of tree kangaroo have low activity levels, with studies observing individual engagement in long periods of rest followed by bouts of locomotion [5]. When not resting, tree kangaroos spend time feeding, foraging [6] and performing vigilance behaviour [7]. Patterns of activity are noted to differ across wild Dendrolagus species, ranging from crepuscular [8] to nocturnal [9].…”

Goodfellow’s tree kangaroos (Dendrolagus goodfellowi) are an endangered, arboreal macropod native to the lower, mid-montane rainforests of Papua New Guinea. Despite a number of holders keeping D. goodfellowi in zoos across the world, there is a lack of recent published work on this species. Here, we present daytime activity budgets, document height use and provide husbandry information for two Goodfellow’s tree kangaroos (Dendrolagus goodfellowi buergersi) housed at Chester Zoo, UK. Throughout the observation period, both individuals spent the majority of their time resting within the environment but also spent time engaging in vigilance, travel and feeding behaviour. Additionally, despite the age and sex differences of the study individuals, both animals used the highest height level in the indoor habitat most frequently. We aim to share our information and encourage knowledge transfer with other holders, to both increase understanding and promote evidence-based management of this species.
