Thawing permafrost and contaminated sediment in marine coastal areas pose some of the greatest risks for the production of highly toxic methylmercury, according to findings published in the journal Science Advances.
As record ocean temperatures cause widespread coral bleaching across Hawaii, NOAA scientists confirm the same stressful conditions are expanding to the Caribbean and may last into the new year, prompting the declaration of the third global coral bleaching event ever on record.
The Government of Chile announced today at the Our Oceans Summit in Valparaiso its plan to design a network of Marine Protected Areas for the purpose of safeguarding Patagonia’s whales, dolphins, sea lions, sea birds and other coastal biodiversity, an initiative that would expand the country’s protected waters by 100,000 square kilometers (more than 38,000 square miles).
New research shows that butterflies in Greenland have become smaller in response to increasing temperatures due to climate change.
The sensitivity of leaf unfolding phenology to climate warming has significantly declined since 1980s, according to a study recently published in the journal Nature by an international collaboration of scientists. Earlier spring leaf unfolding is a frequently observed response of plants to climate warming. Many deciduous tree species require cold temperatures, in other words ‘chilling’, for dormancy release, and the warming-related reductions in chilling may counteract the advance of leaf unfolding in response to warming. Empirical evidence for this, however, was very limited.
A landmark study published in Nature Climate Change today by Australian and British scientists predicts that climate change will have a major impact on life in Antarctica this century.
Offshore wind farms which are to be built in waters around the UK could pose a greater threat to protected populations of gannets than previously thought, according to a new study by researchers at the universities of Leeds, Exeter and Glasgow.
Protected areas not only keep significant swaths of Indonesia's shrinking mangrove habitats intact, but also prevent emissions of carbon dioxide that would have been released had these mangroves been cleared, according to a study in the journal Ecological Economics.
The world's grassy biomes are key contributors to biodiversity and ecosystem services, and are under immense pressure from conversion to agriculture and tree planting, report Joseph W. Veldman, of Iowa State University, and his colleagues in an article for the October issue of BioScience.
As fish-eating predators at the top of the marine food chain, elephant seals accumulate high concentrations of mercury in their bodies. A new study by scientists at UC Santa Cruz shows that elephant seals shed significant amounts of mercury during molting, resulting in elevated concentrations of the toxic metal in coastal waters near the elephant seal rookery at Año Nuevo State Reserve.
