Abstract Improved natural resource governance is critical for the effective conservation of ecosystems, and the well-being of societies that depend on them. Understanding the social fit of institutional arrangements in different contexts can help guide the design of effective environmental governance. This empirical study assessed individual-level variation in institutional acceptance of coral reef governance among 652 respondents in 12 fishing and tourism-oriented communities in the Wider Caribbean. High institutional acceptance was strongly associated with perceptions of community cohesiveness, underlining the potential contribution of civil society to effective governance processes. Institutional acceptance was also influenced by reef use, awareness of rules, perceived [...]

Abstract Species invasions often occur at geographic scales that preclude complete eradication, setting up long term battles for population control. To understand the extent to which exotic species removal by volunteers can contribute to local invasion suppression and alleviate invasion effects, we studied the activities of volunteers culling invasive lionfish during annual ‘derby' events in the Atlantic. From 2012–2014, single day derbies reduced lionfish densities by 52% over 192 km2 on average each year. Differences in recolonization and productivity between regions meant that annual events were sufficient to suppress the invasion below levels predicted to cause declines in native species in [...]

Abstract Every year, hundreds of millions of animals die in collisions with cars. For some species, road strikes are a major cause of population declines, and reducing collisions is a conservation priority. We suggest that the emergence of automated vehicles will provide new opportunities for the use of computerised animal warning systems and variable speed zones in areas (and times) of high collision risk—but only if conservation biologists play a role in the development and implementation of these vehicles on the road.

Abstract Nature conservation and social equity issues have been approached in a myriad of ways by conservation, humanitarian, and development practitioners. The rapid and shifting urbanization of the globe makes the interaction of these issues paramount and it is imperative to articulate pathways to harmonizing these relationships readily followed by conservation practitioners. We describe the processes and compare the resulting social equity and conservation objectives of two initiatives purposefully integrating these approaches. A private nonprofit seeking to develop an urban conservation program in the Atlanta metropolitan area purposefully engaged residents from surrounding communities and self-identified local and sector leaders to identify [...]

Abstract It can be difficult to establish the conservation significance of endemic infectious diseases – those that are well established in a population – in contrast with infectious diseases that are still invading. This difficulty can have important implications for designing policy to address species declines. The infectious diseases of koalas provide an ideal case study to examine issues involved in identifying the role of endemic disease in conservation biology. Koala populations are in decline, amidst claims for many years that infectious diseases, particularly those with chlamydial aetiology, play a key role in this loss. However, weak associations between prevalence of [...]

Abstract Meeting the multi-million hectare commitments for forest and landscape restoration (FLR) will require billions of tree seed and seedlings. However, the adequacy of seed supply in terms of quantity, genetic diversity and quality has received scant attention in FLR planning. We surveyed 139 FLR projects worldwide and identified widespread problems in the availability and diversity of tree seed, with potentially deleterious consequences for the vigour, productivity and long-term persistence of restored tree populations. Large projects and those focused on climate change mitigation were particularly associated with multiple problems in seed sourcing. To avoid large-scale failure in FLR, we recommend: (1) [...]

Abstract Conservation practitioners face complex challenges due to resource limitations, biological and socioeconomic trade-offs, involvement of diverse interest groups, and data deficiencies. To help address these challenges, there are a growing number of frameworks for systematic decision making. Three prominent frameworks are structured decision making, systematic conservation prioritization, and systematic reviews. These frameworks have numerous conceptual linkages, and offer rigorous and transparent solutions to conservation problems. However, they differ in their assumptions and applicability. Here, we provide guidance on how to choose among these frameworks for solving conservation problems, and how to identify less rigorous techniques when time or data availability [...]

Abstract Using choice modeling, we explore willingness to pay for rhino horn among existing and potential future consumers in Vietnam. We find that wild-sourced horn, harvested humanely from the least rare species, is the most highly valued product. Furthermore, consumers are willing to pay less for rhino horn products under a scenario where international trade is legalized compared to the current situation of illegal trade. We discuss the potential implications of our findings on rhino poaching and international trade policy. [...]

Abstract Many countries have made statutory commitments to ensure that underwater noise pollution is at levels which do not harm marine ecosystems. Nevertheless, coordinated action to manage cumulative noise levels is lacking, despite broad recognition of the risks to ecosystem health. We attribute this impasse to a lack of quantitative management targets—or “noise budgets”—which regulatory decision-makers can work toward, and propose a framework of risk-based noise exposure indicators which make such targets possible. These indicators employ novel noise exposure curves to quantify the proportion of a population or habitat exposed, and the associated exposure duration. This methodology facilitates both place-based and [...]
