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...
The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These enable users to calculate temporal trends biodiversity within amongst using a broad range of metrics. is being developed as community-led open-source time series. Our goal accelerate facilitate quantitative analysis patterns the Anthropocene.The 8,777,413 abundance records, from consistently sampled for minimum 2 years, which need not necessarily be consecutive. In...
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 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 Background ‘Megafire’ is an emerging concept commonly used to describe fires that are extreme in terms of size, behaviour, and/or impacts, but the term’s meaning remains ambiguous. Approach We sought resolve ambiguity surrounding ‘megafire’ by conducting a structured review use and definition term several languages peer‐reviewed scientific literature. collated definitions descriptions megafire identified criteria frequently invoked define megafire. recorded size location megafires...
Climate change is increasing the frequency and severity of short-term (~1 y) drought events—the most common duration drought—globally. Yet impact this intensification on ecosystem functioning remains poorly resolved. This due in part to widely disparate approaches ecologists have employed study drought, variation studied, differences among ecosystems vegetation, edaphic climatic attributes that can mediate impacts. To overcome these problems better identify factors modulate responses, we...
Human actions are causing widespread increases in fire size, frequency, and severity diverse ecosystems globally. This alteration of regimes is considered a threat to numerous animal species, but empirical evidence how shifting within both threatened species’ ranges protected areas scarce, particularly at large spatial temporal scales. We used big data approach quantify multidecadal changes southern Australia from 1980 2021, spanning 415 reserves (21.5 million ha) 129 including birds,...
Although variation in effect sizes and predicted values among studies of similar phenomena is inevitable, such far exceeds what might be produced by sampling error alone. One possible explanation for results differences researchers the decisions they make regarding statistical analyses. A growing array has explored this analytical variability different fields found substantial despite analysts having same data research question. Many these have been social sciences, but one small "many...
Abstract Invasive mammalian predators are major drivers of species extinctions globally. To protect native prey, lethal control is often used with the aim reducing or exterminating invasive predator populations. The efficacy this practice, however, not considered despite multiple practical and ecological factors that can limit success. Here, we summarize contemporary knowledge regarding use challenges both alternative approaches for impacts. As prevailing management approach, outline four...
Abstract Aim The aim was to determine how reptile populations respond anthropogenic habitat modification and whether species traits environmental factors influence such responses. Location Global. Time period 1981–2018. Major taxa studied Squamata. Methods We compiled a database of 56 studies reporting affects abundance calculated standardized mean differences in (Hedges’ g ). used Bayesian meta‐analytical models test responses depended on body size, clutch reproductive mode, specialization,...
Since European occupation of Australia, human activities have caused the dramatic decline and sometimes extinction many continent’s unique species. Here we provide a comprehensive review threats to species listed as threatened under Australia’s Environment Protection Biodiversity Conservation Act 1999. Following accepted global categories threat, find that invasive affect largest number (1257 species, or 82% all species); ecosystem modifications (e.g. fire) (74% species) agricultural...
ABSTRACT Biodiversity faces many threats and these can interact to produce outcomes that may not be predicted by considering their effects in isolation. Habitat loss fragmentation (hereafter ‘fragmentation’) altered fire regimes are important biodiversity, but interactions have been systematically evaluated across the globe. In this comprehensive synthesis, including 162 papers which provided 274 cases, we offer a framework for understanding how interacts with fragmentation. Fire three main...
Context Feral cats (Felis catus) are a threat to biodiversity globally, but their impacts upon continental reptile faunas have been poorly resolved. Aims To estimate the number of reptiles killed annually in Australia by and list Australian species known be cats. Methods We used (1) data from >80 studies cat diet (collectively >10 000 samples), (2) estimates feral population size, model map Key results Australia’s natural environments kill 466 million yr–1 (95% CI; 271–1006 million)....
