While the world focuses on controlling global warming caused by CO2 emissions from fossil fuels, less attention has been paid to the capacity of vegetation and soils to take up and store carbon. A remote field site in the Norwegian mountains is improving our understanding of carbon cycling in high-latitude alpine areas.
Ribbed mussels can remove nitrogen and other excess nutrients from an urban estuary and could help improve water quality in other urban and coastal locations, according to a study in New York City's Bronx River. The findings, published in Environmental Science and Technology, are part of long-term efforts to improve water quality in the Bronx River Estuary.
Researchers test a variety of incentives to learn how best to motivate farmers to curb phosphorus runoff.
Researchers at IMDEA Networks (Spain) in collaboration with University of Haifa (Israel) have developed an underwater acoustic system for the localization of marine mammals, underwater vehicles and other sound sources in the ocean, using no more than a single hydrophone (basically an underwater microphone) as a receiver.
Mussels protect themselves against environmental disturbances and enemies through a hard, calcareous shell. Increased ocean acidification makes it difficult for organisms to form their shells. In a study published today, in the international journal, Nature Communications, a group of scientists from the Kiel University and GEOMAR Helmholtz Centre for Ocean Research Kiel show that mussel larvae react sensitively to ocean acidification, which leads to reduced calcification rates and shell dissolution.
It's found that the skill scores for EP events were significantly better than those for CP events at all lead times. The possible reasons are related to the systematic forecast biases coming mostly from the prediction of CP events; and systematic error characterized by an overly warm eastern Pacific during the spring season, indicating a stronger spring prediction barrier for CP El Niño.
Here's some advice for landowners wanting to remove pine trees in the hope of seeing fynbos plants on their properties again: do so before the trees have grown there for more than 30 years. The longer they wait, the less likely the chances that any fynbos seeds will be left in the soil to sprout successfully, according to researchers from Stellenbosch University and the City of Cape Town, in the South African Journal of Botany.
Large, physically strong Masu salmon disperse farther when infected with parasites, potentially escaping from further infections at the contaminated site but ironically resulting in the greater expansion of the parasite, according to Hokkaido University researchers.
Natural habitats play a vital role in helping other plants and animals resist heat stresses ramping up with climate change -- at least until the species they depend on to form those habitats become imperiled.
Aerial drone footage of bowhead whales in Canada's Arctic has revealed that the large mammals molt and use rocks to rub off dead skin.
