Modelling the spread of introduced ecosystem engineers is a conservation priority due to their potential cause irreversible ecosystem‐level changes. While existing models predict distributions and capacities, new approaches that simulate trajectory species' over time are needed. We developed novel simulations spatial temporal spread, capturing both continuous diffusion‐dispersal occasional long‐distance leaps. focused on population superb lyrebird Menura novaehollandiae in Tasmania,...

Conservation and natural resource management are frequently hampered by poor understanding of how species distributions have changed over time. Species Distribution Models (SDMs) correlate known occurrences with environmental variables to predict a species’ potential range. These models can then be projected unsurveyed areas or time periods overcome gaps in data on distribution. The eastern quoll Dasyurus viverrinus is restricted Tasmania but until recently occurred large area south-eastern...

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....

ContextTasmania has been called the roadkill capital of Australia. However, little is known about population-level impact vehicle mortality on native mammals in island state. AimsThe aims were to investigate predictability a given route, based models species distribution and live animal abundance for three marsupial Tasmania – Tasmanian pademelon (Thylogale billardierii), Bennett’s wallaby (Macropus rufogriseus) bare-nosed wombat (Vombatus ursinus) assess possibility predicting magnitude...

Global road networks facilitate habitat modification and are integral to human expansion. Many animals, particularly scavengers, use roads as they provide a reliable source of food, such carrion left after vehicle collisions. Tasmania is often cited the 'roadkill capital Australia', with isolated offshore islands in Bass Strait experiencing similar, if not higher, levels roadkill. However, native mammalian predators on extirpated, meaning remaining scavengers likely experience lower...

Context Vehicle collisions with wildlife can injure or kill animals, threaten human safety, and the viability of rare species. This has led to a focus in road-ecology research on identifying key predictors ‘road-kill’ risk, goal guiding management mitigate its impact. However, because complex context-dependent nature causes risk exposure, modelling road-kill data ways that yield consistent recommendations proven challenging. Aim Here we used multi-model machine-learning approach identify...

Future land-use change could supplement populations of opportunistic predatory birds, such as corvids, resulting in amplified predation pressure and negative effects on other avian species. We investigated whether Forest Ravens (Corvus tasmanicus) were more likely to be observed modified landscapes areas higher roadkill density south-eastern Tasmania. Following this, we examined the effect Raven abundance birds. surveyed birds along roadsides investigate raven population presence smaller...

Woodland birds are increasingly threatened by the impacts of environmental change. As global population and economy grow, we continue to modify habitat for human use, reducing available nesting foraging opportunities birds. In addition, post-European occupation has led introduction alien species, like cats (Felis catus), expansion generalist corvids, resulting in increased predation competition vulnerable bird species. To successfully preserve habitats, manage invasive species conserve both...

Abstract 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. In this study, we use a natural ‘removal experiment’ disease-driven decline island extirpation native mammalian (marsupial) to investigate top-down control on utilisation experimentally placed carcasses two mesoscavengers – invasive feral cat forest raven....

Abstract Conserving nomadic species is challenging due to the difficulty in monitoring their characteristically transient populations, and thereby detecting range-wide declines. An example Yellow-tailed Black-Cockatoo (YTBC; Zanda funerea ), which disperses widely search of food regularly—but sporadically—observed across eastern Australia. Under climate warming, a general southward shift distributions expected southern hemisphere, with extreme margins being truncated by an ocean barrier....
