New guidelines drafted by a consortium of concerned experts could enable corals to adapt to changing environments and help restore declining populations in the Caribbean. The guidelines provide a definitive plan for collecting, raising, and replanting corals that maximizes their potential for adaptation. [...]

Fussy fish seeking refuge from climate change on deeper reefs can still keep their specialized diets. The corals they prey upon change their own diets to survive the different environment at depth. This ensures their fussy predators are still well-fed! [...]

Abstract Threats to ecosystems are closely linked to human development, whereas lack, insufficiency, and inefficiency of public policies are important drivers of environmental decline. Previous studies have discussed the contribution of IUCN's Red List of Ecosystems (RLE) in conservation issues; however, its applications in different policy fields and instruments for achieving biodiversity conservation have not been explored in detail. Here, we introduce a framework to operationalize the RLE in public policy, facilitating work of governments, practitioners, and decision makers. Our analysis identified 20 policy instruments that could reduce risks to ecosystems highlighted by different Red List criteria. We discuss how RLE [...]

Abstract No net loss (NNL) biodiversity policies mandating the application of a mitigation hierarchy (avoid, minimize, remediate, offset) to the ecological impacts of built infrastructure are proliferating globally. However, little is known about their effectiveness at achieving NNL outcomes. We reviewed the English‐language peer‐reviewed literature (capturing 15,715 articles), and identified 32 reports that observed ecological outcomes from NNL policies, including >300,000 ha of biodiversity offsets. Approximately one‐third of NNL policies and individual biodiversity offsets reported achieving NNL, primarily in wetlands, although most studies used widely criticized area‐based outcome measures. The most commonly cited reason for success was applying high offset multipliers [...]

The first major study into the impact of inshore potting for crab and lobster within a Marine Protected Area has found that in areas of low potting intensity the industry is operating in a way that had little impact on seabed species or economically-important shellfish. [...]

Coral bleaching is not just due to a warming planet, but also a planet that is simultaneously being enriched with reactive nitrogen from sources like improperly treated sewage, and fertilizers. Nitrogen loading from the Florida Keys and greater Everglades ecosystem caused by humans is the primary driver of coral reef degradation in Looe Key. These coral reefs were dying off long before they were impacted by rising water temperatures. Elevated nitrogen levels cause phosphorus starvation in corals, reducing their temperature threshold for bleaching. [...]

The acidification of the oceans is recorded in the crystals of the coral skeleton. This is a new tool for studying past environmental changes and combating climate change. Such is the main conclusion of a study led by the Spanish scientist Ismael Coronado Vila, from the Institute of Paleobiology in Warsaw (Poland). [...]

Coral reefs are retreating from equatorial waters and establishing new reefs in more temperate regions, according to new research. The researchers found that the number of young corals on tropical reefs has declined by 85 percent -- and doubled on subtropical reefs -- during the last four decades. [...]

Abstract The priority of an area for conservation is determined by three primary factors: its biodiversity value, the level of threat it is facing, and its cost. Although much attention has been paid to the spatial relationship between biodiversity value and threats, and between biodiversity value and costs, little is known about how costs and threats are spatially correlated. The orthodox assumption in conservation science is that costs and threats are positively correlated. Here, we adapt a classic economic theory of land use to explain how conservation scientists came to expect a positive correlation between costs and threats. We then use [...]
