The most urgent course of action to safeguard coral reefs is to reduce global greenhouse gas emissions, but concurrently there is also a need to consider novel management techniques and previously over-looked reef areas for protective actions under predicted climate change impacts. The conclusions were reached following a comprehensive review of the literature on the mechanisms of potential coral resistance and recovery across scales from global reef areas to the microbial level within individual corals.

Abstract This article identifies, and offers several ways to address, a serious, persistent issue in conservation: low levels of diversity in thought and action. We first describe the lack of diversity and highlight the continued separation of the environmental conservation and environmental justice movements. We then offer—based on previous research and our collective experience—two suggestions for how to increase inclusivity (a step farther than increasing diversity) in holistic ways. We suggest that embracing narrative, including historical narrative that can be profound and painful, may be essential to addressing this deeply rooted issue. We also suggest the need to redefine “environment” to [...]

Abstract Current methods in conservation planning for promoting the persistence of biodiversity typically focus on either representing species geographic distributions or maintaining connectivity between reserves, but rarely both, and take a focal species, rather than a multi-species, approach. Here, we link prioritisation methods with population models to explore the impact of integrating both representation and connectivity into conservation planning for species persistence. Using data on 288 Mediterranean fish species with varying conservation requirements, we show that: (i) considering both representation and connectivity objectives provides the best strategy for enhanced biodiversity persistence; and (ii) connectivity objectives were fundamental to enhancing persistence of [...]

Abstract The clear evidence of the accumulating impacts of anthropogenic actions on the Earth system is driving researchers to look to historical data as a resource for understanding the present and predicting the future. In the conservation science literature, using historical sources usually refers to data mining ‘the past' using the scientific methods of historical ecology. This paper considers the often overlooked methodological challenges of sourcing and interpreting historical data. A schema is provided for conservation scientists, summarising the kinds of questions and metadata required to work rigorously with historical data. This will improve the accuracy of the data we use [...]

Abstract Targeting phylogenetic diversity (PD) in systematic conservation planning is an efficient way to minimize losses across the Tree of Life. Considering representation of genetic diversity below and above species level, also allows robust analyses within systems where taxonomy is in flux. We use dense sampling of phylogeographic diversity for eleven lizard genera, to demonstrate how PD can be applied to a policy-ready conservation planning problem. Our analysis bypasses named taxa, using genetic data directly to inform conservation decisions. We highlight areas that should be prioritised for ecological management, and also areas that would provide the greatest benefit if added to [...]

Abstract Protected areas (PAs) represent a cornerstone of efforts to safeguard biodiversity, and if effective should reduce threats to biodiversity. We present the most comprehensive assessment of threats to terrestrial PAs, based on in situ data from 1,961 PAs across 149 countries, assessed by PA managers and local stakeholders. Unsustainable hunting was the most commonly reported threat and occurred in 61% of all PAs, followed by disturbance from recreational activities occurring in 55%, and natural system modifications from fire or its suppression in 49%. The number of reported threats was lower in PAs with greater remoteness, higher control of corruption, and [...]

Scientists have used a new research approach to show that warming temperatures are turning one of the world's largest sea turtle colonies almost entirely female, running the risk that the colony cannot sustain itself in coming decades, newly published research concludes. [...]

Abstract The global portfolio of protected areas is growing rapidly, despite widely recognized shortfalls in management effectiveness. Pressure to meet area-coverage and management effectiveness objectives makes it essential to determine how limited conservation funds should be allocated between expanding protected area networks and better enforcing existing reserves. We formally explore this question for the particular case of an exploited species in a partially protected system, using a general model linking protection, enforcement and legal/illegal resource extraction. We show that, on average, funds should be disproportionately invested in enforcement rather than expansion. Further, expansion alone, without additional enforcement, can actually reduce conservation [...]

For the first time, an international team of researchers has measured the escalating rate of coral bleaching at locations throughout the tropics over the past four decades. The study documents a dramatic shortening of the gap between pairs of bleaching events, threatening the future existence of these iconic ecosystems and the livelihoods of many millions of people.

Forty percent of the world's 7.6 billion people live in coastal cities and towns. A team of marine biologists just released 25 years of data about the health of Caribbean coasts. The study provides new insights into the influence of both local and global stressors in the basin, and some hope that the observed changes can be reversed by local environmental management. [...]

For years, people have sought to stop the loss of coral reefs by transplanting corals grown in underwater 'nurseries' to damaged reefs, but little work had been done to evaluate how effective such efforts were. A new study, however, suggests those projects have a positive impact on local fish populations, both in the short term and over time. [...]
