Abstract The growing interest in payment-based incentives as a policy tool requires robust evidence regarding the effectiveness of alternative payment structures in eliciting pro-conservation behavior. How incentives are structured not only determines how much individual resource users can be influenced, but also impacts wider co-benefits, such as building the capacity of local institutions or changing social norms. Gatiso et al. (2017) contribute to this evidence base with their experimental study of individual- and group-based payments to promote sustainable community forestry. Two important points arise from their study: i) how group and individual incentives are defined and ii) the need for fair [...]

Abstract International political boundaries challenge species conservation because they can hinder coordinated management. Peripheral transboundary species, those with a large portion of their range in one country and a small, peripheral portion in an adjacent country, may be particularly vulnerable to mismatches in management because peripheral populations are likely in greater conservation need than core populations. However, no systematic assessment of peripheral transboundary species or their status across borders has been attempted. We show that numerous species in three vertebrate taxa qualify as peripheral transboundary species in North America, and that these species are often protected differently across US-Canadian and US-Mexican [...]

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 computerized 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 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 etiology, play a key role in this loss. However, weak associations between prevalence of infection, clinical signs of [...]

Abstract Agricultural land use is a key interface between the goals of ensuring food security and protecting biodiversity. “Land sparing” supports intensive agriculture to save land for conservation, whereas “land sharing” integrates production and conservation on the same land. The framing around sparing versus sharing has been extensively debated. Here, we focused on a frequently missing yet crucial component, namely the governance dimension. Through a case-study in Ethiopia, we uncovered stakeholder preferences for sparing versus sharing, the underlying rationale, and implementation capacity challenges. Policy stakeholders preferred sparing whereas implementation stakeholders preferred sharing, which aligned with existing informal institutions. Implementation of both [...]

Fishes' fear of sharks helps shape shallow reef habitats in the Pacific, according to new research. The study is the first clear case of sharks altering a coral reef ecosystem through an indirect effect - creating an atmosphere of fear that shifts where herbivores feed and seaweeds grow. [...]

Abstract Meeting the multimillion 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 vigor, 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 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 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 [...]
