If you pay attention to plants, you already know non-native species are commonplace. Queen Anne's lace, chicory and garlic mustard — familiar sights along our roads — are just a handful of the species brought to the U.S. for medicinal or edible purposes.

Invasive species typically are referred to as those moved from their native range by human activity and, having established themselves in the wilds of the new place, cause ecological or economic harm.

A new study in New York reveals that ticks are more likely to be infected with several pathogens, not just the bacterium that causes Lyme disease. The ticks for the study were collected from Dutchess County.

The Harvard Forest, in collaboration with the Cary Institute of Ecosystem Studies, has launched a new Science Policy Exchange project on forest pests and pathogens. This project addresses growing concerns about damage to trees, forests, and local economies caused by introduced insects. 

Biogeochemist Kathleen Weathers studies the chemicals and living organisms in fog or mist. Illuminating the chemical relationships among water, land, forests and the ocean increases our understanding of the ecological importance of fog and air pollution.

People who get bitten by a blacklegged tick have a higher-than-expected chance of being exposed to more than one pathogen at the same time.

In America's Southeastern states, there's a booming energy trend that's as big a step backward as imaginable.

The Hudson River includes a stretch where tides affect the river as much at its mouth near Manhattan as 150 miles inland at Troy, N.Y. Most of that section is freshwater.

We've all heard the expression, "Think global, act local." In the environmental context, its popularity no doubt comes from a sense of reassurance — that by taking small, personal steps, we can make a difference.

Ninety one researchers from institutions across the country have signed a letter urging the EPA to follow the latest science on climate impacts from Biomass Energy.

A terrestrial ecologist at Cary, Clive Jones' work focuses on the concept of organisms that help to engineer the ecosystem. In this interview, he talks about the relationship between ecological engineering and ecological compensation. 

The Hudson River has changed in many far-reaching ways over the past quarter-century as a result of human activity. Zebra mussels and other invasive species have changed the river's ecology.

For New York to achieve its goals in the Obama administration's plan to reduce carbon emission from power plants, the state will have to do more than cut back on dirty fuel

Fresh off of a study that showed mice don't die any quicker as uninfected ticks pile onto them, the Cary Institute of Ecosystem Studies is launching research that will examine how mice fare after they get Lyme disease.

There’s a dramatic recovery underway in New England. Red spruce, a tree species that researchers thought was doomed because of acid rain, is now growing faster than ever, and it’s not the only tree growing like gangbusters.

Urban waterways have been channeled, diverted, buried and polluted for centuries, but they have only recently been studied as part of the larger urban ecosystem.

When Chris Standley received a tip that some ash trees within the Mohonk Preserve might be infested by a devastating insect, he grabbed a drawknife and peeled away the bark.

Dr. Gene E. Likens, President Emeritus and Distinguished Senior Scientist at the Cary Institute of Ecosystem Studies, was the 2014 recipient of the Alfred C. Redfield Lifetime Achievement Award.

Sending a robotic airboat disguised as a crocodile to look for hippo poop in Kenya's Mara River sounds like a hilarious idea, but it wasn't so funny when the hippopotamus started chasing the robot.

Small, autonomous airboats masquerading as crocodiles gathered data on hippo hygiene and water quality this spring in Kenya. Cary's Emma Rosi-Marshall was there.
