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.
Bearded dragons which are incubated in colder environments are better at solving cognitive tasks as adults than incubated in warmer temperatures, according to new research published today. Scientists from the University of Lincoln, UK, tested the social learning abilities of bearded dragons which had been incubated in either an average of 30°C or 27°C and found that those from the colder incubation environment picked up new skills faster than their hotter counterparts.
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.
Due to climate change, including rising temperatures, more and more methane is bubbling up from lakes, ponds, rivers and wetlands throughout the world. The release of methane -- a potent greenhouse gas -- leads to a further increase in temperature, thus creating a positive feedback loop (also known as a 'vicious circle'). This is the conclusion of a team of biologists led by Radboud University in an article published in Nature Communications on Nov. 22.
Trade of wild birds has dropped 90 percent globally since EU banned bird imports in 2005. A new study in Science Advances demonstrates how it decreased the number of birds traded annually from 1.3 million to 130,000. International trade of wild birds is a root cause of exotic birds spreading worldwide. The study was led by Center for Macroecology, Evolution and Climate, University of Copenhagen and CIBIO-InBIO Research Centre in Biodiversity and Genetic Resources, University of Porto.
Municipalities, enterprises, and households are switching to LED lights in order to save energy. But these savings might be lost if their neighbors install new or brighter lamps. Scientists fear that this 'rebound effect' might partially or totally cancel out the savings of individual lighting retrofit projects, and make skies over cities considerably brighter.
