Covert rewilding: Modelling the detection of an unofficial translocation of Tasmanian devils to the Australian mainland
Abstract Covert rewilding is the secret and illegal translocation of species in the pursuit of conservation objectives. Recent history contains multiple covert rewilding events, frequently occurring after official permission was denied. In order to better understand the phenomenon, I formulate…

Modeling herbivore functional responses causing boom‐bust dynamics following predator removal
Abstract Native biodiversity is threatened by invasive species in many terrestrial and marine systems, and conservation managers have demonstrated successes by responding with eradication or control programs. Although invasive species are often the direct cause of threat to native species…

Superadditive and subadditive dynamics are not inherent to the types of interacting threat.
Species and ecosystems usually face more than one threat. The damage caused by these multiple threats can accumulate nonlinearly: either subadditively, when the joint damage of combined threats is less than the damages of both threats individually added together, or superadditively, when the joint…

Recent advances of quantitative modeling to support invasive species eradication on islands
Abstract The eradication of invasive species from islands is an important part of managing these ecologically unique and at‐risk regions. Island eradications are complex projects and mathematical models play an important role in supporting efficient and transparent decision‐making. In this review…

Australian birds could benefit from predator exclusion fencing
Abstract The use of predator exclusion fencing is widely recognized as one of the most effective mechanisms for protecting threatened fauna from introduced or overabundant predators. It is now used throughout the world to protect avian fauna. In Australia, where predator exclusion fencing is used…

Costs are not necessarily correlated with threats in conservation landscapes
Abstract The priority of an area for conservation is determined by three primary factors: its biodiversity value, the level of threat it is facing, and its cost. Although much attention has been paid to the spatial relationship between biodiversity value and threats, and between biodiversity value…

Optimising crown-of-thorns starfish control effort on the Great Barrier Reef.
Outbreaks of crown-of-thorns starfish Acanthaster planci (COTS), a disruptive coral-eating predator, are responsible for almost half of total coral cover loss on Australia's Great Barrier Reef. As the pressures of climate change continue to intensify the frequency and severity of disturbance events…

Reserves in Context: Planning for Leakage from Protected Areas.
When protected areas reduce threats within their boundaries, they often displace a portion of these threats into adjacent areas through a process known as 'leakage', undermining conservation objectives. Using theoretical models and a case study of terrestrial mammals in Indonesia, we develop the…

Lost in the South: A Roman Copper Ingot from the area of Tarragona in the Baetica
Se presenta un lingote de cobre romano recuperado de un pecio ubicado en la región fronteriza de las provincias de Málaga y Cádiz. Con un diámetro de 45 a 53 cm y un peso de 75.4 kg, es uno de los galápagos de cobre más pesados que se conocen. La abreviatura de un nombre y su peso están escritos…

Introduced species that overcome life history tradeoffs can cause native extinctions
Introduced species may displace ecologically similar native species, but mechanisms are still to be established. Here, Catford et al. provide theoretical evidence of how human-mediated species invasions may overcome competition-colonisation tradeoffs, leading to the local extinction of native…

Synthesis and review: delivering on conservation promises: the challenges of managing and measuring conservation outcomes
Growing threats and limited resources have always been the financial realities of biodiversity conservation. As the conservation sector has matured, however, the accountability of conservation investments has become an increasingly debated topic, with two key topics being driven to the forefront of…

Optimal conservation outcomes require both restoration and protection.
Conservation outcomes are principally achieved through the protection of intact habitat or the restoration of degraded habitat. Restoration is generally considered a lower priority action than protection because protection is thought to provide superior outcomes, at lower costs, without the time…

The context dependence of frontier versus wilderness conservation priorities
Abstract Much of conservation planning has focused on how we should prioritize areas for protection based on biodiversity and cost, but less is known about how we should prioritize areas based upon the level of threat they face. We discuss two opposing threat prioritization strategies: frontier…

Fish aggregating devices could enhance the effectiveness of blue water marine protected areas
Abstract In the past two decades, drifting fish aggregation devices (FADs) have revolutionized pelagic fisheries, and are now responsible for the majority of tuna purse seine catches. Here, we argue that by taking advantage of the same proven aggregative properties, FADs could be used to enhance…

The relative conservation impact of strategies that prioritize biodiversity representation, threats, and protection costs
Abstract Despite exponential increases in the coverage of protected areas (PAs) over recent decades, global biodiversity continues to decline. One explanation for this lack of success is that the efficacy of conservation prioritization strategies is rarely measured in terms of conservation…
