Top carnivores have suffered widespread global declines, with well-documented effects on mesopredators and herbivores. We know less about how affect ecosystems through scavenging. Tasmania's top carnivore, the Tasmanian devil (Sarcophilus harrisii) , has severe disease-induced population providing a natural experiment role of scavenging in structuring communities. Using remote cameras experimentally placed carcasses, we show that consume more carrion areas where devils declined. Carcass...
The challenge that large carnivores face in coexisting with humans calls into question their ability to carry out critical ecosystem functions such as mesopredator suppression outside protected areas. In this study, we examined the movements and fates of mesopredators across rural landscapes characterized by substantial human influences. Mesopredators shifted toward areas twofold-greater influence regions occupied carnivores, indicating they perceived be less a threat. However, rather than...
Changes to the spatiotemporal patterns of wildfire are having profound implications for ecosystems and society globally, but we have limited understanding extent which fire regimes will reorganize in a warming world. While predicting regime shifts remains challenging because complex climate-vegetation-fire feedbacks, climate niches provides simple way identify locations most at risk change. Using globally available satellite datasets, constructed 14 metrics describing dimensions then...
Top predators cause avoidance behaviours in competitors and prey, which can lead to niche partitioning facilitate coexistence. We investigate changes of the temporal a mammalian community response both rapid decline abundance top predator its increase, produced by two concurrent natural experiments: 1) severe Tasmanian devil due transmissible cancer, 2) introduction devils an island, with subsequent population increase. focus on devils, mesopredators three prey species, allowing us examine...
Recent experiments have demonstrated that carnivores and ungulates in Africa, Asia, Europe North America fear the human 'super predator' far more than other predators. Australian mammals been a focus of research on predator naiveté because it is suspected they show atypical antipredator responses. To experimentally test if Australia also most humans, we quantified responses four native marsupials (eastern grey kangaroo, Bennett's wallaby, Tasmanian pademelon, common brushtail possum)...
Global declines of large carnivores have reduced the ‘landscape fear’ that constrains behaviour other species. In recent years, active and passive trophic rewilding potentially begun restoring these lost top–down controls. The Tasmanian devil Sarcophilus harrisii has declined severely due to a novel transmissible cancer. response extinction fears, devils were introduced devil‐free Maria Island, where their abundance rapidly increased. We tested how this introduction influenced risk‐sensitive...
Understanding the spatial dynamics and drivers of wildlife pathogens is constrained by sampling logistics, with implications for advancing field landscape epidemiology targeted allocation management resources. However, visually apparent diseases, when combined remote-surveillance distribution modelling technologies, present an opportunity to overcome this landscape-scale problem. Here, we investigated disease, using clinical signs sarcoptic mange (caused Sarcoptes scabiei) in its bare-nosed...
Snowpack dynamics have a major influence on wildlife movement ecology and predator–prey interactions. Specific snow properties such as density, hardness, depth determine how much an animal sinks into the snowpack, which in turn drives both energetic cost of locomotion predation risk. Here, we quantified relationships between five field‐measured variables track sink depths for widely distributed predators (bobcats Lynx rufus , cougars Puma concolor coyotes Canis latrans wolves C. lupus )...

Abstract Dry lightning is a prevalent episodic natural ignition source for wildfires, particularly in remote regions where such fires can escalate into uncontrollable events, burning extensive areas. In this study, we aimed to understand the interplay of environmental, fuel, and geographical factors evaluating probability fire initiation following dry strikes Tasmania, Australia. We integrated lightning, active records, gridded data on weather, topography binary classification framework both...
ABSTRACT Carrion acts as a hotspot of animal activity within many ecosystems globally, attracting scavengers that rely on this food source. However, are invasive species whose impacts scavenging webs and ecosystem processes linked to decomposition poorly understood. Here, we use Australia case study review the extent by have colonised continent since European settlement, identify factors influence their carcasses, highlight lesser‐known ecological effects scavengers.

We provide data on the timing and frequency of bellowing episodes 261 copulations in North American bison (Bison bison) extracted from more than 8500 h observation to examine Darwin's idea that by using breeding-season vocalizations male "endeavours thus charm or excite female." Copulatory status affected vocalization rates; after mating, dropped 16.1% precopulatory rates (p < .0001). Males bellowed at a higher rate days when females were estrus .025) they anestrus, but females' probability...
Scavenging by large carnivores is integral for ecosystem functioning limiting the build-up of carrion and facilitating widespread energy flows. However, top have declined across world, triggering trophic shifts within ecosystems. Here, we compare findings from previous work on predator decline against areas with recent native mammalian carnivore loss. Specifically, investigate top-down control utilization experimentally placed carcasses two mesoscavengers—the invasive feral cat forest raven....

Abstract Avoiding the undesirable impacts of invasive species requires robustly evaluating effects alternative management scenarios. Such evaluations depend on reliable spatio‐temporal projections changes in distribution and abundance under different However, commonly used modelling approaches are constrained for this purpose because they do not incorporate demographic processes seldom validated. We develop a spatially temporally explicit grid‐based population model fallow deer Dama dama...

Abstract Devil facial tumor disease (DFTD) is a transmissible cancer affecting Tasmanian devils Sarcophilus harrisii . The has caused severe population declines and associated with demographic behavioral changes, including earlier breeding, younger age structures, reduced dispersal social interactions. Devils are generally solitary, but encounters commonplace when feeding upon large carcasses. DFTD tumors can disfigure the jaw mouth so diseased individuals might alter their diets to enable...
Like many other Australian mammals, eastern quolls (Dasyurus viverrinus) were widespread in the south-east of mainland Australia but went extinct there during 20th century. The species remained abundant Tasmania until it rapidly declined from 2001 to 2003, coinciding with a period unsuitable weather. We provide an updated analysis quoll population trends using time series annual spotlight counts (1985–2019) collected across most species’ range. Eastern and early 2000s. In addition previously...
