World's Sea Life Is 'Facing Major Shock,' Marine Scientists Warn

Life in the world's oceans faces far greater change and risk of large-scale extinctions than at any previous time in human history, a team of the world's leading marine scientists has warned.

Marine Species at Risk Unless Drastic Protection Policies Put in Place

Many marine species will be harmed or won't survive if the levels of carbon dioxide continue to increase.

Losing Stream in Our Battle to Predict and Prevent Invasive Species

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.

Diversity Keeps Grasslands Resilient to Drought Climate Change

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 One of Biggest Contributors to Air Pollution

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.

How Forests Thrive After Fires and Volcanoes

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.

Crayfish Species Proves to Be the Ultimate Survivor

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.

Birds That Live With Varying Weather Sing More Versatile Songs

A new study of North American songbirds reveals that birds that live with fluctuating weather are more flexible singers.



Ancient Coral Reefs at Risk From Deforestation and Land Use Practices

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.

Tropical Climate in the Antarctic

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.

Skin Cancer Identified for the First Time in Wild Fish Populations

Widespread skin cancer has been identified for the first time in wild marine fish populations, new research has shown.

Earth's Ecosystems Still Absorbing About Half the Greenhouse Gases Emitted by People

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.

Underwater Ecosystem Inundated by Sediment Plume

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.

Antiques Dealer Pleads Guilty to Crimes Related to Trafficking Endangered Rhinoceros Horns

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.

Coral Reef Thriving in Sediment-Laden Waters

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.

Cooling, Not Population Loss, Led to Fewer Fires After 1500 in New World

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.

Chronic 2000-04 Drought May Be the New Normal

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.

Fluid Imaging Technologies Enables Rutgers Student to Study Ecosystem Restoration

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.

Federal Court Awarding $1 Million to Preserve North Carolina Wetlands

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.

Environmental Concerns Increasing Infectious Disease in Amphibians

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.
