Significance Invasive mammalian predators are arguably the most damaging group of alien animal species for global biodiversity. Thirty invasive predator implicated in extinction or endangerment 738 vertebrate species—collectively contributing to 58% all bird, mammal, and reptile extinctions. Cats, rodents, dogs, pigs have pervasive impacts, endemic island faunas vulnerable predators. That impacted insular indicates that management on islands should be a conservation priority. Understanding...
Abstract Long‐term ecological studies are critical for providing key insights in ecology, environmental change, natural resource management and biodiversity conservation. In this paper, we briefly discuss five values of such studies. These are: (1) quantifying responses to drivers ecosystem change; (2) understanding complex processes that occur over prolonged periods; (3) core data may be used develop theoretical models parameterize validate simulation models; (4) acting as platforms...
Abstract Aim Predators often have important roles in structuring ecosystems via their effects on each other and prey populations. However, these may be altered the presence of anthropogenic food resources, fuelling debate about whether availability such resources could alter ecological role predators. Here, we review extent to which human‐provided foods are utilised by terrestrial mammalian predators (> 1 kg) across globe. We also assess a direct impact ecology behaviour an indirect...
Top‐order predators often have positive effects on biological diversity owing to their key functional roles in regulating trophic cascades and other ecological processes. Their loss has been identified as a major factor contributing the decline of biodiversity both aquatic terrestrial systems. Consequently, restoring maintaining function top is critical global imperative. Here we review studies dingo Canis lupus , Australia's largest land predator, using this case study explore influence...
Carnivore predation on livestock often leads people to retaliate. Persecution by humans has contributed strongly global endangerment of carnivores. Preventing losses would help achieve three goals common many human societies: preserve nature, protect animal welfare, and safeguard livelihoods. Between 2016 2018, four independent reviews evaluated >40 years research lethal nonlethal interventions for reducing livestock. From 114 studies, we find a striking conclusion: scarce quantitative...
Abstract Aim Reducing the impacts of feral cats ( Felis catus ) is a priority for conservation managers across globe, and success in achieving this aim requires detailed understanding species’ ecology broad spectrum climatic environmental conditions. We reviewed diet cat Australia on Australian territorial islands, seeking to identify biogeographical patterns dietary composition diversity, use results consider how may best be managed. Location its islands. Methods Using 49 published...
Abstract Aichi Target 12 of the Convention on Biological Diversity (CBD) contains aim to ‘prevent extinctions known threatened species’. To measure degree which this was achieved, we used expert elicitation estimate number bird and mammal species whose were prevented by conservation action in 1993–2020 (the lifetime CBD) 2010–2020 timing 12). We found that 21–32 7–16 since 1993, 9–18 two seven 2010. Many remain highly may still become extinct. Considering 10 five did go extinct (or are...
Abstract Feral cats are among the most damaging invasive species worldwide, and implicated in many extinctions, especially Australia, New Zealand other islands. Understanding reducing their impacts is a global conservation priority. We review knowledge about management of feral identify priorities for research management. In well understood significant impact predation on threatened mammals. Other include vertebrates, resource competition, disease transmission, but these remains limited....
Abstract Grey wolves Canis lupus have been studied extensively, but there has no detailed review of the species’ feeding ecology, despite growing debate about how to conserve wolf populations while limiting their impacts on wild or domestic ungulates. Here, we assess extent which grey diet varies among and within North America, Europe, Asia. We derived dietary data from searches published literature. grouped studies based bioregional location. compared locations using non‐metric...
Context Many Australian mammal species are highly susceptible to predation by introduced domestic cats (Felis catus) and European red foxes (Vulpes vulpes). These predators have caused many extinctions driven large distributional population declines for more species. The serendipitous occurrence of, deliberate translocations of mammals to, ‘havens’ (cat- fox-free offshore islands, mainland fenced exclosures capable excluding foxes) has helped avoid further extinction. Aims aim this study was...

Abstract Aim After environmental disasters, species with large population losses may need urgent protection to prevent extinction and support recovery. Following the 2019–2020 Australian megafires, we estimated recovery in fire‐affected fauna, inform conservation status assessments management. Location Temperate subtropical Australia. Time period 2019–2030 beyond. Major taxa terrestrial freshwater vertebrates; one invertebrate group. Methods From > 1,050 taxa, selected 173 whose...
With large wildfires becoming more frequent1,2, we must rapidly learn how megafires impact biodiversity to prioritize mitigation and improve policy. A key challenge is discover interactions among fire-regime components, drought land tenure shape wildfire impacts. The globally unprecedented3,4 2019–2020 Australian burnt than 10 million hectares5, prompting major investment in monitoring. Collated data include responses of 2,000 taxa, providing an unparalleled opportunity quantify affect...
Abstract Forbs (“wildflowers”) are important contributors to grassland biodiversity but vulnerable environmental changes. In a factorial experiment at 94 sites on 6 continents, we test the global generality of several broad predictions: (1) Forb cover and richness decline under nutrient enrichment, particularly nitrogen enrichment. (2) increase herbivory by large mammals. (3) less affected enrichment in more arid climates, because water limitation reduces impacts competition with grasses....
