Protected Areas (PAs) are the cornerstone of biodiversity conservation. Here, we collated distributional data for >14,000 (~70% of) species of amphibians and reptiles (herpetofauna) to perform a global assessment of the conservation effectiveness of PAs using species distribution models. Our analyses reveal that >91% of herpetofauna species are currently distributed in PAs, and that this proportion will remain unaltered under future climate change. Indeed, loss of species’ distributional ranges will be lower inside PAs than outside them.

We are in the midst of a major biodiversity crisis, with deep impacts on the functioning of ecosystems and derived benefits to people (1, 2). But we still have time to pull back. To do so, it is imperative that we learn from plants’ and animals’ past actions (3, 4). Conservation biology, ecology, and paleontology all emphasize that natural systems must exhibit resilience and dynamic responses to rapid environmental changes (3, 5, 6). Both climate and land-use change have accelerated over the past decades, underscoring the urgency for increased understanding and action (7–9).

Many protected areas worldwide increasingly resemble habitat isolates embedded in human-modifed landscapes. However, establishing linkages among protected areas could signifcantly reduce speciesloss rates. Here we present a novel method having broad applicability for assessing enhanced regional connectivity on persistence of mammal diversity. We combine theoretically-derived species relaxation rates for mammal communities with empirically-derived pathways.

Islands  support  unique  plants,  animals,  and  human societies found nowhere else on the Earth. Local and global stressors threaten the persistence of island ecosystems, with invasive species being among the most damaging, yet solvable, stressors. While the threat of invasive terrestrial mammals on island flora and fauna is well recognized, recent studies have begun to illustrate their extended and destructive impacts on adjacent marine environments. Eradication of invasive mammals and restoration of native biota are promising tools to address both island and ocean management goals.

Even optimistic climate scenarios predict catastrophic consequences for coral reef ecosystems by 2100. Understanding how reef connectivity, biodiversity and resilience are shaped by climate variability would improve chances to establish sustainable management practices. In this regard, ecoregionalization and connectivity are pivotal to designating effective marine protected areas.

This paper identifies the Dasgupta Review’s key points about the role of protected areas (PAs) in conserving nature. Using these factors as a foundation, this paper explores how economists can conduct analyses that improve PA decisions and promote both biodiversity conservation and ecosystem service provision. People’s interactions with PAs should be considered when making design, management, and restrictions decisions about PAs because those interactions are critical to determining the threats to biodiversity within PAs and the benefits produced by PAs.

Marine Protected Areas (MPAs) are designed to enhance biodiversity and ecosystem services. Some
MPAs are also established to benefit fisheries through increased egg and larval production, or the

Previous research has cast doubt on the potential for marine protected areas (MPAs) to provide refuge and fishery spillover benefits for migratory species as most MPAs are small relative to the geographic range of these species. We test for evidence of spillover benefits accruing from the world’s largest fully protected MPA, Papahānaumokuākea Marine National Monument. Using species-specific data collected by independent fishery observers, we examine changes in catch rates for individual vessels near to and far from the MPA before and after its expansion in 2016.

Ocean threats: acidification, deoxygenation, warming, heatwaves. Do we have anything useful to bend, change, or reverse the results? This brochure, conceived to advocate and educate at the UNFCCC COP27 meetings, summarises these threats and how various solutions (explained within) can actually help protect the ocean as Nature-based Solutions, if correctly constructed, and the existing and emerging financial mechanisms and institutions that can build and fortify these solutions. 

Marine protected areas (MPAs) are ubiquitous in global ocean conservation and play a pivotal role in achieving local, national, and regional area-based conservation targets. Often, such targets are merely met on “paper” and lack the political or managerial resources to produce positive conservation outcomes. Here, we apply the MPA Guide – a framework for assessing the quantity and quality of marine protected areas – to Guam and the Commonwealth of the Northern Mariana Islands (CNMI), two U.S. territories in the Western Pacific.
