Invasive species -- plants, animals, and microbes introduced to regions beyond their native range -- carry a global price tag of $1.4 trillion dollars. They are responsible for the loss of natural resources and biodiversity, damages to infrastructure, and an uptick in infectious diseases.
For much of the year drought has been plaguing American grasslands. But a recent study found that grasses do not appear to be losing the turf war against climate when it comes to surviving with little precipitation.
Pine trees are one of the biggest contributors to air pollution. They give off gases that react with airborne chemicals -- many of which are produced by human activity -- creating tiny, invisible particles that muddy the air.
Forests hammered by windstorms, avalanches and wildfires may appear blighted, but a Washington State University researcher says such disturbances can be key to maximizing an area's biological diversity.
One of the most invasive species on the planet is able to source food from the land as well as its usual food sources in the water, research from Queen Mary, University of London has found.
A new study of North American songbirds reveals that birds that live with fluctuating weather are more flexible singers.
A team of international scientists, including a researcher from The University of Western Australia, has found that soil erosion, land degradation and climate change pose a mounting threat to coastal reefs and their ecosystems in the western Indian Ocean.
A study published in the journal Nature shows that tropical vegetation, including palms and relatives of today’s tropical Baobab trees, was growing on the coast of Antarctica 52 million years ago.
Earth's oceans, forests and other ecosystems continue to soak up about half the carbon dioxide emitted into the atmosphere by human activities, even as those emissions have increased, according to a study by University of Colorado and NOAA scientists published August 1 in the journal Nature.
Widespread skin cancer has been identified for the first time in wild marine fish populations, new research has shown.
Scuba-diver scientists from the U.S. Geological Survey are returning to the mouth of Washington’s Elwha River this week to explore and catalogue the effect of released sediment on marine life following the nation’s largest dam removal effort.
David Hausman, an antiques dealer in Manhattan, pleaded guilty today in Manhattan federal court to obstruction of justice and creating false records, in relation to illegal rhinoceros horn trafficking.
Rapid rates of coral reef growth have been identified in sediment-laden marine environments, conditions previously believed to be detrimental to reef growth. A new study has established that Middle Reef -- part of Australia's iconic Great Barrier Reef -- has grown more rapidly than many other reefs in areas with lower levels of sediment stress.
In the years after Columbus' voyage, burning of New World forests and fields diminished significantly -- a phenomenon some have attributed to decimation of native populations by European diseases. But a new University of Utah-led study suggests global cooling resulted in fewer fires because both preceded Columbus in many regions worldwide.
The chronic drought that hit western North America from 2000 to 2004 left dying forests and depleted river basins in its wake and was the strongest in 800 years, scientists have concluded, but they say those conditions will become the "new normal" for most of the coming century.
North Carolina’s Waccamaw River watershed will benefit from a $1 million restitution order from a federal court, funding environmental projects to acquire and preserve wetlands in an area damaged by illegal releases of wastewater from a corporate hog farm.
Laboratory instrumentation manufacturer Fluid Imaging Technologies, Yarmouth, Maine (www.fluidimaging.com) has awarded its 2012 FlowCAM® Student Equipment and Travel Grant to Amanda Wenczel, a Ph. D. candidate in Ecology at Rutgers, The State University of New Jersey.
Climate change, habitat destruction, pollution and invasive species are all involved in the global crisis of amphibian declines and extinctions, researchers suggest in a new analysis, but increasingly these forces are causing actual mortality in the form of infectious disease.
Citing recent wildfires in Colorado, Texas, Russia, Greece, and Chile and a report from climate scientists at the University of California, Berkeley and Texas Tech University, a top official at Lloyd’s said insurers face new challenges from wildfires in many parts of the world.
Rat poison used on illegal marijuana farms may be sickening and killing the fisher, a rare forest carnivore that makes its home in some of the most remote areas of California, according to a team of researchers led by University of California, Davis, veterinary scientists.
