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...
The global carbon sequestration and avoided emissions potentially achieved via blue is high (∼3% of annual greenhouse gas emissions); however, it limited by multidisciplinary interacting uncertainties spanning the social, governance, financial, technological dimensions. We compiled a transdisciplinary team experts to elucidate these challenges identify way forward. Key actions enhance as natural climate solution include improving policy legal arrangements ensure equitable sharing benefits;...
Climate change is impacting coral reefs now. Recent pan-tropical bleaching events driven by unprecedented global heat waves have shifted the playing field for reef management and policy. While best-practice conventional remains essential, it may no longer be enough to sustain under continued climate change. Nor will mitigation sufficient on its own. Committed warming projected decline means solutions must involve a portfolio of mitigation, coordinated restoration adaptation measures...
Single species conservation unites disparate partners for the of one species. However, there are widespread concerns that single biases efforts towards charismatic at expense others. Here we investigate extent to which sage grouse (Centrocercus sp.) conservation, largest public-private effort a in US, provides protections other from localized and landscape-scale threats. We compared coverage provided by Priority Areas Conservation (PACs) 81 sagebrush-associated vertebrate distributions with...
Abstract Aim Many alien species experience a lag phase between arriving in region and becoming invasive, which can provide valuable window of opportunity for management. Our ability to predict are experiencing lags has major implications management decisions that worth billions dollars may determine the survival some native species. To date, timing causes release have been identified post hoc, based on historical narratives. Location Global. Methods We use simple but realistic simulation...
Summary Many highly diverse island ecosystems across the globe are threatened by invasive species. Eradications of mammals from islands being attempted with increasing frequency, success aided geographical isolation and knowledge eradication techniques. There have been many attempts to prioritize for species eradication; however, these coarse methods all assume managers unrealistically limited a single action on each island: either eradicate mammals, or do nothing. We define prioritization...
Sustainable Development Goals (SDGs) are a set of priorities the United Nations and World Bank have for countries to reach in order improve quality life environment globally by 2030. Free satellite images been identified as key resource that can be used produce official statistics analysis measure progress towards SDGs, especially those concerned with physical environment, such forest, water, crops. Satellite often unusable due missing data from cloud cover, particularly tropical areas where...
Abstract Mathematical and statistical models underlie many of the world's most important fisheries management decisions. Since 19th century, difficulty calibrating fitting such has been used to justify selection simple, stationary, single‐species aid tactical Whereas these justifications are reasonable, it is imperative that we quantify value different levels model complexity for supporting management, especially given a changing climate, where old methodologies may no longer perform as well...
Abstract Value of information (VoI) analysis is a method for quantifying how additional may improve management decisions, with applications ranging from conservation to fisheries. However, VoI studies frequently suggest that collecting more data will not substantially outcomes. This often contradicts the intuition ecologists and managers who usually believe new critical management. inconsistency exacerbated by perception black‐box method. A lack understanding as why lower than expect...
Abstract Understanding the trade‐offs between biodiversity conservation and agricultural production has become a fundamental question in sustainability science. Substantial research focused on how species’ populations respond to intensification, with goal understand whether policies that spatially separate agriculture or, alternatively, integrate two are more beneficial. Spatial heterogeneity both species abundance productivity have been largely left out of this discussion, although these...
Fences that exclude alien invasive species are used to reduce predation pressure on reintroduced threatened wildlife. Planning these continuously managed systems of reserves raises an important extension the Single Large or Several Small (SLOSS) reserve planning framework: added complexity ongoing management. We investigate long-term cost-efficiency a single large two small predator exclusion fences in arid Australian context reintroducing bilbies Macrotis lagotis, and we highlight broader...
Abstract Payments to private landholders for providing biodiversity land can improve conservation outside protected areas. Input‐based payments are widely used despite evidence they often ineffective at improving outcomes. Meanwhile, little has been done assess how use outcome‐based maximize biodiversity, growing academic interest. We compare different allocation methods which returns the greatest benefits biodiversity. predicted likely landholder actions in response payments. incorporated...
Abstract Management of public lands, and who should have access to them, is often contentious. Most ranches in the western US rely upon seasonal grazing conflict over biodiversity management has led proposals restrict on lands. We evaluate whether restrictions rangelands could unintended effect increasing conversion private rangeland cropland, causing habitat loss for sage‐grouse, a species conservation concern. Using model parameterized with empirical observations land use change ranch...

Summary The conservation of many threatened species can be advanced by the eradication alien invasive animals from islands. However, island eradications are an expensive, difficult and uncertain undertaking. An increasingly common strategy is construction ‘interior fences’ to partition islands into smaller, independent regions that treated sequentially or concurrently. Proponents argue that, while interior fences incur substantial up front costs, they reduce overall costs. this hypothesis...
Abstract Threatened species with reduced and fragmented habitats can be reintroduced into their historical ranges to establish new populations. Multiple sites might an option for reintroductions; therefore, managers must determine when open (e.g. infrastructure improve conditions), release individuals those sites, eventually cease releases. Careful planning of this schedule, incorporating the cost actions, is imperative at outset a program. To address challenge, we consider reintroduction...
