Abstract There is little appreciation of the level extinction risk faced by one‐sixth over 65,000 species assessed International Union for Conservation Nature. Determining status these data‐deficient (DD) essential to developing an accurate picture global biodiversity and identifying potentially threatened DD species. To address this knowledge gap, we used predictive models incorporating species’ life history, geography, threat information predict conservation terrestrial mammals. We...
Abstract Societal, economic and scientific interests in knowing where biodiversity is, how it is faring what can be done to efficiently mitigate further loss the associated of ecosystem services are at an all‐time high. So far, however, monitoring has primarily focused on structural compositional features ecosystems despite growing evidence that functions key elucidating mechanisms through which biological diversity generates humanity. This gap traced current lack consensus exactly track...
Abstract In response to growing demand for ecosystem‐level risk assessment in biodiversity conservation, and rapid proliferation of locally tailored protocols, the IUCN recently endorsed new Red List criteria as a global standard ecosystem assessment. Four qualities were sought design criteria: generality; precision; realism; simplicity. Drawing from extensive consultation, we explore trade‐offs among these when dealing with key challenges, including classification, measuring dynamics,...
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...
Biodiversity loss is a major challenge. Over the past century, average rate of vertebrate extinction has been about 100-fold higher than estimated background and population declines continue to increase globally. Birth death rates determine pace or decline, thus driving expansion species. Design species conservation policies hence depends on demographic data (e.g., for risk assessments estimation harvesting quotas). However, an overview accessible data, even better known taxa, lacking. Here,...
Abstract Aim Evaluating the relative roles of biological traits and environmental factors that predispose species to an elevated risk extinction is fundamental importance macroecology. Identifying possess extinction‐promoting allows targeted conservation action before precipitous declines occur. Such analyses have been carried out for several vertebrate groups, with notable exception reptiles. We identify correlating high in squamate reptiles, assess whether these differ geography, taxonomy...
One in 6 species (13,465 species) on the International Union for Conservation of Nature (IUCN) Red List is classified as data deficient due to lack information their taxonomy, population status, or impact threats. Despite chance that many are at high risk extinction, data-deficient typically excluded from global and local conservation priorities, well funding schemes. The number will greatly increase IUCN becomes more inclusive poorly known speciose groups. A strategic approach urgently...
Abstract In 2014, the International Union for Conservation of Nature adopted Red List Ecosystems (RLE) criteria as global standard assessing risks to terrestrial, marine, and freshwater ecosystems. Five years on, it is timely ask what impact this new initiative has had on ecosystem management conservation. policy perspective, we use an evaluation framework distinguish outputs, outcomes, impacts RLE since its inception. To date, 2,821 ecosystems in 100 countries have been assessed following...
Abstract Governments have committed to global targets slow biodiversity loss and sustain ecosystem services. Biodiversity state indicators that measure progress toward these mostly focus on species, while synthesizing change are largely lacking. We fill this gap with three indices quantifying past projected changes in ecosystems using data from the International Union for Conservation of Nature (IUCN) Red List Ecosystems. Our quantify risk collapse, area ecological processes, capture...
Effective ecosystem risk assessment relies on a conceptual understanding of dynamics and the synthesis multiple lines evidence. Risk protocols models integrate limited observational data with threat scenarios, making them valuable tools for monitoring status diagnosing key mechanisms decline to be addressed by management. We applied IUCN Red List Ecosystems criteria quantify collapse Meso-American Reef, unique containing second longest barrier reef in world. collated wide array empirical...
Abstract Aim Less than 6% of the worlds described plant species have been assessed on IUCN Red List, leaving many invisible to conservation prioritization. Large‐scale List assessment is a challenge, as most species’ ranges only resolved coarse scale. As geographic distribution key criterion we evaluate use coarse‐scale data in predictive models assess global scale and drivers extinction risk an economically important group, bulbous monocotyledons. Location Global. Methods Using data, train...
Summary Cost‐effective reduction of uncertainty in global biodiversity indicators is a central goal conservation. Comprising sixth the 74 000+ species currently on IUCN Red List, Data Deficient contribute to considerable estimates extinction risk. Estimating levels risk will require large resources given costs surveys and List assessments. Predicting from traits geographical information could provide cheaper approach for determining proportion at extinction. We use double sampling theory...
Abstract Aim To investigate the impact of different treatments IUCN D ata eficient ( DD ) category on taxonomic and geographical patterns extinction risk in crayfish, freshwater crabs dragonflies. Location Global. Methods We used contingency tables to evaluate selectivity data deficiency for three invertebrate groups (crayfish, dragonflies damselflies, crabs) based their Red List status. investigated differences among families, realms families within each groups. At level, we evaluated...
Abstract Aim Stochastic threats such as disease outbreak, pollution events, fire, tsunami and drought can cause rapid species extinction ecosystem collapse. The ability of a or to persist after stochastic threat is strongly related the extent spatial pattern its geographical distribution. Consequently, protocols for assessing risks biodiversity typically include geographic range size criteria from threats. However, owing in part rarity events nature, metrics risk categories have never been...
Global biodiversity indices are used to measure environmental change and progress toward conservation goals, yet few have been evaluated comprehensively for their capacity detect trends of interest, such as declines in threatened species or ecosystem function. Using a structured approach based on decision science, we qualitatively 9 commonly track at global regional scales against 5 criteria relating objectives, design, behavior, incorporation uncertainty, constraints (e.g., costs data...
Abstract Aim Climate change is a major threat to the persistence of biodiversity. Global assessments highlight most climate vulnerable species and geographic regions based on traits measures exposure change. Yet majority vulnerability have focused terrestrial marine vertebrates largely ignored less well‐known freshwater invertebrates. We present first global analysis 574 crayfish (Families: Astacidae, Parastacidae Cambaridae) using IUCN 's trait‐based assessment protocol. Location Global....
