Loss of large predators disrupting multiple plant, animal and human ecosystems
The enormous decline of large, apex predators and "consumers" ranging from wolves to lions, sharks and sea otters may represent the most powerful impacts humans have ever had on Earth's ecosystems, a group ...
Melting Arctic opens new passages for invasive species
For the first time in roughly 2 million years, melting Arctic sea ice is connecting the north Pacific and north Atlantic oceans. The newly opened passages leave both coasts and Arctic waters vulnerable to ...
Dispersal patterns key to invasive species' success
In 1859 an Australian farmer named Thomas Austin released 24 grey rabbits from Europe into the wild because it "could do little harm and might provide a touch of home, in addition to a spot of hunting."
In whole-lake experiment, have invasive crayfish met their match?
Four years ago, UW-Madison researchers wrapped up a multi-year effort to dramatically reduce the population of a destructive invasive species in a northern Wisconsin lake.
Kudzu can release soil carbon, accelerate global warming
Clemson University scientists are shedding new light on how invasion by exotic plant species affects the ability of soil to store greenhouse gases. The research could have far-reaching implications for how ...
Antarctica faces major threats in the 21st century: researchers
The continent of Antarctica is at risk from human activities and other forces, and environmental management is needed to protect the planet's last great wilderness area, says an international team of researchers, including ...
In US, struggle against snakehead ends on plates
The snakehead is an invasive species of fish from Asia that is threatening the delicate ecosystem of the Potomac River that flows through Washington into the Atlantic Ocean.
Scientists look into Earth's 'deep time' to predict future effects of climate change
Climate change alters the way in which species interact with one another—a reality that applies not just to today or to the future, but also to the past, according to a paper published by a team of researchers ...
Researchers revise Darwin's thinking on invasive species
For more than a century and a half, researchers interested in invasive species have looked to Charles Darwin and what has come to be called his "naturalization conundrum." If an invader is closely related to species in a ...
Sea lampreys fear the smell of death
A repellant for sea lampreys could be the key to better controlling one of the most destructive invasive species in the Great Lakes, says a Michigan State University researcher.
Scientists identify key fungal species that help explain mysteries of white nose syndrome
U.S. Forest Service researchers have identified what may be a key to unraveling some of the mysteries of White Nose Syndrome: the closest known non-disease causing relatives of the fungus that causes WNS. ...
Environmental threat map highlights Great Lakes restoration challenges
A comprehensive map three years in the making is telling the story of humans' impact on the Great Lakes, identifying how "environmental stressors" stretching from Minnesota to Ontario are shaping the future ...
Scientists warn of tourism threat to Antarctica
Antarctic scientists warned Wednesday that a surge in tourists visiting the frozen continent and new roads and runways built to service research facilities were threatening its fragile environment.
Researchers demonstrate new DNA detection technique
