Mercury in the Nation’s Streams—Levels, Trends, and Implications

Mercury is a potent neurotoxin that accumulates in fish to levels of concern for human health and the health of fish-eating wildlife. Mercury contamination of fish is the primary reason for issuing fish consumption advisories, which exist in every State in the Nation. Much of the mercury originates from combustion of coal and can travel long distances in the atmosphere before being deposited. This can result in mercury-contaminated fish in areas with no obvious source of mercury pollution.

Due to landscape fragmentation, Brazil's rainforests are releasing more carbon dioxide than previously thought

Because of the deforestation of tropical rainforests in Brazil, significantly more carbon has been lost than was previously assumed. As scientists of the Hemholtz Centre for Environmental Research (UFZ) write in the scientific journal Nature Communications, the effect of the degradation has been underestimated in fragmented forest areas, since it was hitherto not possible to calculate the loss of the biomass at the forest edges and the higher emission of carbon dioxide. The UFZ scientists have now closed this knowledge gap. According to their calculations, the forest fragmentation results in up to a fifth more carbon dioxide being emitted by the vegetation.

Study: Creepy Crawlers Play Key Role in Structure of Grasslands

When asked to describe a forest or a meadow, most people would probably begin with the plants, the species diversity, or the color of the foliage. They probably wouldn’t pay much attention to the animals living in the soil.

New study suggests humans to blame for plummeting numbers of cheetahs

A new study led by Queen's University Belfast into how cheetahs burn energy suggests that human activity, rather than larger predators, may force them to expend more energy and thus be the major cause of their decline.

If trees could talk: Forest research network reveals global change effects

Permafrost thaw drives forest loss in Canada, while drought has killed trees in Panama, southern India and Borneo. In the U.S., in Virginia, over-abundant deer eat trees before they reach maturity, while nitrogen pollution has changed soil chemistry in Canada and Panama. Continents apart, these changes have all been documented by the Smithsonian-led Center for Tropical Forest Science-Forest Global Earth Observatory, CTFS-ForestGEO, which released a new report revealing how forests are changing worldwide.

New Report Highlights Ten American Species Our Children May Never See

Our children are less likely to see monarch butterflies, a bumblebee, and a host of other once-common wildlife species due to farm pesticides, declining ocean health, climate change and dirty energy production, according to a new report by the Endangered Species Coalition. The report, Vanishing: Ten American Species Our Children May Never See, highlights ten disappearing species and the causes of their dramatic population declines. Additionally, the report identifies everyday actions that people can take to help slow the disappearance of our nation's iconic wildlife.

Study identifies gauntlet of man-made obstacles facing migrating pronghorn in greater Yellowstone

One of North America's last remaining long-distance land migrations, better known as the Path of the Pronghorn, is being threatened by a mosaic of natural gas field development, highway traffic, and fencing in the upper Green River Basin, according to the Wildlife Conservation Society. WCS scientists used a model traditionally applied to identify resource related stopovers for migrating animals in order to identify impediments to migration of pronghorn.

Report: The Urgent Case for a Ban on Fracking

In recent years, the term "fracking" has come to mean far more than just the specific process of extracting oil and natural gas by injecting large volumes of various mixes of water, sand and chemicals deep underground, at extreme pressure, to create fractures in targeted rock formations.

Drought bites as Amazon’s ‘flying rivers’ dry up

The unprecedented drought now affecting São Paulo, South America's giant metropolis, is believed to be caused by the absence of the "flying rivers" − the vapour clouds from the Amazon that normally bring rain to the centre and south of Brazil.The unprecedented drought now affecting São Paulo, South America's giant metropolis, is believed to be caused by the absence of the "flying rivers" − the vapour clouds from the Amazon that normally bring rain to the centre and south of Brazil.

Study maps 15 years of carbon dioxide emissions on Earth

World leaders face multiple barriers in their efforts to reach agreement on greenhouse gas emission policies. And, according to Arizona State University researchers, without globally consistent, independent emissions assessments, climate agreements will remain burdened by errors, self-reporting, and the inability to verify emissions progress.

Rare Lynx Finally Gain Federal Protection Throughout U.S. But Feds Fall Short in Revising Critical Habitat

After eight years of advocacy and litigation by WildEarth Guardians (Guardians) and the Western Environmental Law Center (WELC), today the U.S. Fish and Wildlife Service (Service) finally announced it will list the New Mexico population of Canada lynx as threatened with extinction under the Endangered Species Act, and extend that protection to wherever lynx occur in the contiguous United States.

Research Shows Historic Decline in Pacific Walrus Population

The Pacific walrus population roughly halved between 1981 and 1999, the last year for which demographic data are available. A recent study by scientists at the U.S. Geological Survey quantifies this historic population decline. The 18 year decline identified by the study was not steady across that period. The decline was most severe in the mid-1980s, and then moderated in the 1990s.

Lawsuit Launched to Stop Out-of-control Wildlife Killing by Secretive Federal Agency in Idaho

Four conservation organizations today filed a notice of intent to sue the U.S. Department of Agriculture's Wildlife Services program over its large-scale, often secretive killing of wild animals in Idaho. The program kills millions of animals nationwide every year, and in 2013 killed more than 3,000 mammals in Idaho alone via aerial gunning, neck snares, foothold traps, and toxic devices known as M-44s that spray sodium cyanide into the victim's mouth, causing tremendous suffering and releasing toxic chemicals into the environment.

Climate Change Science Aided by Huge but "Invisible" Efforts of Amateurs

Hundreds of thousands of volunteer data collectors are due for some thanks from scientists, according to a new paper that reveals the role of citizen science in studies of birds and climate change. Data collected by amateurs underpins up to 77 percent of the studies in this field, but that fact is largely invisible by the time the research appears in journals, according to a study published today in the open-access journal PLOS ONE.

Fish and Wildlife Service Urged to Speed Protection for Bat

Two dozen conservation and animal-welfare groups sent a letter today urging the U.S. Fish and Wildlife Service to complete its plan to protect the northern long-eared bat, a species found primarily in the eastern and midwestern United States. Opposition to the bat's protection under the Endangered Species Act — from timber, mining and energy industries as well as several state natural-resource agency officials — prompted the Fish and Wildlife Service to postpone a final decision on protecting the bat until spring 2015.
