A new estimate of bat deaths caused by wind turbines concludes that more than 600,000 of the mammals likely died this way in 2012 in the contiguous United States. The estimate, published in an article in BioScience, used sophisticated statistical techniques to infer the probable number of bat deaths at wind energy facilities from the number of dead bats found at 21 locations, correcting for the installed power capacity of the facilities.
Devoted to an assessment of climate change effects on ecosystems and the consequences for people, the November issue of the Ecological Society of America's journal "Frontiers in Ecology and the Environment" contains papers from a diverse group of more than 50 ecological scientists, including UC Santa Barbara's Joshua Schimel, professor and chair of the Environmental Studies Program.
Growth in offshore wind generation is expected to play a major role in meeting carbon reduction targets around the world, but the impact of construction noise on marine species is yet unknown. A group of scientists from the United Kingdom and the United States have developed a method to assess the potential impacts of offshore wind farm construction on marine mammal populations, particularly the noise made while driving piles into the seabed to install wind turbine foundations. Their work is published in the November issue of Environmental Impact Assessment Review.
Antibiotics, urban pesticides, and other contaminants accumulate where wastewater is released into Lake Geneva. Using computer simulations, EPFL researchers have shown that the risk they pose is highest during summer and that they degrade most efficiently during the winter.
Traces of past microbial life in sediments off the coast of Peru document how the microbial ecosystem under the seafloor has responded to climate change over hundreds of thousands of years. For more a decade scientists at the Max Planck Institute for Marine Microbiology and their colleagues at MARUM and the University of Aarhus have investigated microbial life from this habitat.
An ambitious new study that includes Lisa Levin of Scripps Institution of Oceanography at UC San Diego describes the full chain of events by which ocean biogeochemical changes triggered by manmade greenhouse gas emissions may cascade through marine habitats and organisms, penetrating to the deep ocean and eventually influencing humans.
Coal-powered synthetic natural gas plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke University researchers.
Two professors in the Stanford School of Earth Sciences – David Lobell, an associate professor of environmental Earth system science and Kevin Boyce, an associate professor of geological and environmental sciences – have been named 2013 MacArthur Fellows.
A new UC Santa Barbara study shows that threats created by overfishing can be identified decades before the fish species at risk experience high overly harvest rates and subsequent population declines.
Chancellor Pradeep K. Khosla will today announce a five-year, $20 million award from the National Science Foundation to support an innovative program of research and education on how interactions between air and sea alter the chemistry of the atmosphere to influence climate.
