Abstract Maintaining biodiversity is a central tenet of conservation, in part because biodiversity influences ecosystem functions across terrestrial, freshwater, and marine systems. Biodiversity-ecosystem function relationships have clear relevance for the design of habitat restoration efforts, yet the degree to which biodiversity has been incorporated into restoration practice is unclear. We conducted a review of the published literature on habitat restoration to evaluate this potential science-practice gap. The number of published restoration studies including the term biodiversity has increased slightly from 1990 to 2015 relative to the broader restoration literature. A greater percentage of empirical restorations, and a higher percentage of those [...]

Cool-water corals can adapt to a slightly warmer ocean, but only if global greenhouse gas emissions are reduced, a study has found. Some corals in the normally cool waters of the Cook Islands carry genetic variants that predispose them to heat tolerance. This could help the population adapt more quickly to rising temperatures. But they may not adapt quickly enough to outpace climate change. [...]

Abstract Most conservation scientists and practitioners are unaware that their corpses can transform into protected areas after death. The practice is called a conservation burial, where burial fees fund the acquisition, protection, restoration, and management of new land to benefit human and environmental well-being. If conservation burials became commonplace, then the revenue generated could exceed the amount of money required to fund the conservation of every threatened species on the planet. The additional human-health benefits of increased urban greenspace could also be substantial. As Halloween, “the day of the dead,” approaches, we urge governments, NGOs, and the public to contemplate how [...]

Abstract We quantified the avoided deforestation impacts of environmental land registration in Brazil's Amazonian states of Mato Grosso and Pará between 2005 and 2014. We find that the program reduced deforestation on registered lands. The magnitude of the effect implies that deforestation in the two states would have been 10% higher in the absence of the program. The impacts of registration varied over time, likely due to changing suites of policies linking environmental registration to land use incentives. Our results also reveal that agriculturally suitable lands and those located in regions undergoing the most land-use change were more likely to be [...]

Abstract In February 2014, India's 14th Finance Commission added forest cover to the formula that determines the amount of tax revenue the central government distributes annually to each of India's 29 states. The Government of India estimates that from 2015 to 2019 it will distribute $6.9–$12 billion per year to states in proportion to their 2013 forest cover, amounting to around $174–$303 per hectare of forest per year. Assuming that contemporary forest cover will remain an element of the formula beyond 2020, Indian states now have a sizeable new fiscal incentive to protect and restore forests, contributing to the achievement of [...]

A new study based on the first global survey of marine life by scuba divers has provided fresh insights into how climate change is affecting the distribution of marine life. The research predicts that as the oceans warm fish -- which appear to be superior predators in warm water -- will extend their ranges away from the equator and cause a decline in the diversity of invertebrates such as crabs, lobsters, sea urchins and whelks.

Abstract In coral reef conservation and management, the prevailing metric of reef health is percent coral cover, a measurement commonly used with the assumption that each unit of live coral tissue has equivalent ecological value. Here we show that the reproductive output of a coral population is not proportional to the cover of coral present. Instead, when compared to declining populations nearby, high cover coral populations produced up to four times more larvae per square centimeter of tissue, resulting in up to 200 times higher larval production per square meter of reef. Importantly, corals that produced more larvae did not produce [...]

Abstract Marine reserves are a commonly applied conservation tool, but their size is often chosen based on considerations of socioeconomic rather than ecological impact. Here, we use a simple individual-based model together with the latest empirical information on home ranges, densities and schooling behaviour in 66 coral reef fishes to quantify the conservation effectiveness of various reserve sizes. We find that standard reserves with a diameter of 1–2 km can achieve partial protection (≥50% of the maximum number of individuals) of 56% of all simulated species. Partial protection of the most important fishery species, and of species with diverse functional roles, [...]
