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.
An international research team led by UCLA life scientists has, for the first time, quantified the direct influence of climate on the growth of ecosystems around the globe.
When it comes to using our natural resources, human beings want to know what we're going to get. We expect clean water every time we turn on the tap; beaches free of algae and bacteria; and robust harvests of crops, fish and fuel year after year. As a result, we try to manage the use of our resources in a way that minimizes their variability.
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).
King crabs may soon become high-level predators in Antarctic marine ecosystems where they haven't played a role in tens of millions of years, according to a new study led by Florida Institute of Technology.
Fluctuations in extreme weather events, such as heavy rains and droughts, are affecting ecosystems in unexpected ways -- creating "winners and losers" among plant species that humans depend upon for food.
Mercury contamination in water and on land is of worldwide concern due to its toxic effects on ecosystems and human health. Mercury toxicity is of particular concern to reptiles because they are currently experiencing population declines.
Methane emissions from Arctic tundra increase when sea ice melts, according to a new study from Lund University in Sweden. This connection has been suspected before, but has lacked strong evidence until now.
Through reconstruction we are able to understand the ecological processes which took place in the past, extrapolate our results to the future, predicts the changes in biocenoses under specific ecological and climatic conditions, - explains Larissa Frolova, Research Associate at the Paleoclimatology, Paleoecology, and Paleomagnetism Lab of the Institute of Fundamental Medicine and Biology. - This is very important and is directly tied to the economy. Climatic changes influence biota, environment, and our lives.
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.
