Abstract The International Union for Conservation of Nature's (IUCN) Red List is the global standard for quantifying extinction risk but assessing population reduction (criterion A) of wide‐ranging, long‐lived marine taxa remains difficult and controversial. We show how Bayesian state–space models (BSSM), coupled with expert knowledge at IUCN Red List workshops, can combine regional abundance data into indices of global population change. To illustrate our approach, we provide examples of the process to assess four circumglobal sharks with differing temporal and spatial data‐deficiency: Blue Shark (Prionace glauca), Shortfin Mako (Isurus oxyrinchus), Dusky Shark (Carcharhinus obscurus), and Great Hammerhead (Sphyrna mokarran). For each [...]

Abstract As coral reefs continue to decline due to climate change and other stressors, scientists have proposed adopting genomic tools, such as biomarkers, to aid in the conservation and restoration of these threatened ecosystems. Biomarkers are easily measured indicators of biological processes that can be used to predict or diagnose health, resilience, and other key performance metrics. The ultimate goal of developing biomarkers is to determine the conservation value and utility of a given coral colony, including the host animal, its algal symbionts, and their microbial partners. However, this goal remains distant because most efforts have not yet moved beyond the [...]

Abstract Strategies for mitigating climate change through altered land management practices can provide win–win outcomes for the environment and the economy. Emissions trading for greenhouse gas (GHG) abatement in Australia's remote, fire‐prone, and sparsely populated tropical savannas provides a financial incentive for intensive fire management that aims to reduce fire frequency, severity, and extent, and it supports important social, economic, and land management opportunities for remote communities, conservation agencies, and pastoralists. These programs now cover >20% of Australia's 1.9 million km2 tropical savanna biome, encompassing areas of globally significant biodiversity value. A common assertion is that by reducing the frequency, severity, [...]

Abstract To what extent and how do men and women differ in their attitudes about poaching? Although research suggests that women can be more concerned about environmental degradation than men, inquiries about communities in protected areas are ambiguous: women are disproportionately affected by anti‐poaching laws and can have greater motivations to violate rules. We conducted a large‐scale survey in communities within the Great Limpopo Transfrontier Park in Mozambique, South Africa, and Zimbabwe and explored attitudes regarding; concern about resources, rule compliance, poaching, and anti‐poaching activities. Although women's attitudes generally are not divergent from men's, we find some differences among nonelectrified households [...]

Abstract Governments have committed to global targets to slow biodiversity loss and sustain ecosystem services. Biodiversity state indicators that measure progress toward these targets mostly focus on species, while indicators synthesizing ecosystem change are largely lacking. We fill this gap with three indices quantifying past and projected changes in ecosystems using data from the International Union for Conservation of Nature (IUCN) Red List of Ecosystems. Our indices quantify changes in risk of ecosystem collapse, ecosystem area and ecological processes, and capture variation in underlying patterns among ecosystems. We apply the indices to three case studies of regional and national assessments (American/Caribbean [...]

Abstract As with most governments worldwide, Australian governments list threatened species and proffer commitments to recovering them. Yet most of Australia's imperiled species continue to decline or go extinct and a contributing cause is inadequate investment in conservation management. However, this has been difficult to evaluate because the extent of funding committed to such recovery in Australia, like in many nations, is opaque. Here, by collating disparate published budget figures of Australian governments, we show that annual spending on targeted threatened species recovery is around U.S.$92m (AU$122m) which is around one tenth of that spent by the U.S. endangered species recovery [...]

Abstract Thousands of species worldwide are threatened with extinction due to human activities. For some animals, such as elephants, totoaba, and bluefin tuna, population declines are largely driven by hunting. High prices and large profits create a strong incentive for illegal hunting, even in the face of penalties and strict international restrictions against trade. One innovative solution to help reverse the declines of such species is to farm them to increase supply, thereby reducing prices and decreasing hunting incentives. However, this idea has been criticized as impractical, though some examples exist of successful implementation. Here, we evaluate the hurdles facing endangered [...]

Abstract Seafood certifications are a prominent tool being used to encourage sustainability in marine fisheries worldwide. However, questions about their efficacy remain the subject of ongoing debate. A main criticism is that they are not well suited for small‐scale fisheries or those in developing nations. This represents a dilemma because a significant share of global fishing activity occurs in these sectors. To overcome this shortcoming and others, a range of “fixes” have been implemented, including reduced payment structures, development of fisheries improvement projects, and head‐start programs that prepare fisheries for certification. These adaptations have not fully solved incompatibilities, instead creating new [...]
