As mass coral bleaching events grow in frequency and intensity, scientists are finding out more about how corals, which make up the physical foundation of reefs, respond during times of heat stress. But what is less well known is how mass bleaching events affect other components of reef ecosystems, such as their amazingly colorful array […]
When the United Nations began negotiations on a legally binding treaty to protect and regulate the high seas, one diplomat pointedly remarked: “It’s a jungle out there”—characterizing a wide-o
More than a third of all elasmobranch (shark and ray) species are at risk of extinction due to overfishing. Indonesia is both a hotspot of elasmobranch biodiversity and one of the leading shark and ray exporters in the world, putting already critically endangered species such as hammerhead sharks and wedgefish under great pressure. Reducing that […]
New research has found that carefully managed fisheries can help dwindling shark and ray populations recover, illustrating a pathway for protecting species from fishing pressure. Published in the Proceedings of the National Academy of Sciences, the study analyzed several decades’ worth of trends in fishing pressure, fisheries management, and population status of 26 shark and […]
Scientists remember the years between 2014 and 2017 as a particularly bad time for coral reefs. Elevated temperatures fueled by an El Niño climate pattern harmed about three-quarters of the world’s reefs in both hemispheres, forcing corals to release their life-sustaining zooxanthellae and turning them ghostly white in a process known as coral bleaching. About […]
