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...
This article provides a context to, attempts an explanation for, and proposes response to the recent demonstration of rapid severe decline native mammal fauna Kakadu National Park. is consistent with, but might be more accentuated than, declines reported elsewhere in northern Australia; however, such comparison constrained by sparse information base across this region. Disconcertingly, has similarities with earlier phase extinctions that occurred Australia. We considered four proximate...
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...
Summary Apex predators can benefit ecosystems through top–down control of mesopredators and herbivores. However, apex are often subject to lethal aimed at minimizing attacks on livestock. Lethal affect both the abundance behaviour predators. These changes could in turn influence mesopredators. We used remote camera surveys nine pairs large Australian rangeland properties, comparing properties that controlled dingoes Canis lupus dingo with did not, test effects predator activity evaluate...
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 Globally, collapse of ecosystems—potentially irreversible change to ecosystem structure, composition and function—imperils biodiversity, human health well‐being. We examine the current state recent trajectories 19 ecosystems, spanning 58° latitude across 7.7 M km 2 , from Australia's coral reefs terrestrial Antarctica. Pressures global climate regional impacts, occurring as chronic ‘presses’ and/or acute ‘pulses’, drive collapse. Ecosystem responses 5–17 pressures were categorised...
Apex predators perform important functions that regulate ecosystems worldwide. However, little is known about how ecosystem regulation by influenced human activities. In particular, are top-down effects of relative to direct and indirect human-mediated bottom-up processes? Combining data on species' occurrence from camera traps hunting records, we aimed quantify the processes in shaping predator prey distributions a human-dominated landscape Transylvania, Romania. By global standards this...
Efficient and reliable monitoring of wild animals in their natural habitats is essential to inform conservation management decisions. Automatic covert cameras or "camera traps" are being an increasingly popular tool for wildlife due effectiveness reliability collecting data unobtrusively, continuously large volume. However, processing such a volume images videos captured from camera traps manually extremely expensive, time-consuming also monotonous. This presents major obstacle scientists...
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...
The causes of amphibian deformities and their role in widespread declines remain conjectural. Severe limb abnormalities were induced at high frequencies Pacific treefrogs (Hyla regilla) exposed to cercariae a trematode parasite (Ribeiroia sp.). closely matched those observed field sites, an increase density caused abnormality frequency decline tadpole survivorship. These findings call for further investigation infection as cause other sites species.
Parasites and pathogens can influence the survivorship, behavior, very structure of their host species. For example, experimental studies have shown that trematode parasites cause high frequencies severe limb malformations in amphibians. In a broad-scale field survey covering parts California, Oregon, Washington, Idaho, Montana, we examined relationships between frequency types morphological abnormalities amphibians abundance parasite infection, pH, concentrations 61 pesticides, levels...
Summary Rapid environmental change is placing increasing pressure on the survival of many species globally. Ecological refuges can mitigate impacts by facilitating or persistence organisms in face disturbance events that would otherwise lead to their mortality, displacement extinction. Refuges may have a critical influence successional trajectory and resilience ecosystems, yet function remains poorly understood. We review describe role faunal conservation context fire, globally important...
Invasive species are regarded as one of the top five drivers global extinction crisis. In response, extreme measures have been applied in an attempt to control or eradicate invasives, with little success overall. We tested idea that state shifts invasive dominance symptomatic losses ecosystem resilience, due suppression apex predators. This concept was investigated Australia where high rate mammalian extinctions is largely attributed destructive influence species. Intensive pest widely...
