Millions of diverse inland waters rush, meander, and seep throughout our planet, teeming with life. These streams, lakes, wetlands, and groundwaters are home to thousands of species, many of which are extraordinary and some of which are critically endangered.

Lead author of the report "Towards a Green Economy," Pavan Sukhdev explores how the greening of economies is an engine for growth, a source of employment, and a means of alleviating poverty. 

Deer ticks, known for transmitting Lyme disease, are moving farther north. The longhorned tick, which came from overseas, has gained a foothold on the East Coast and begun moving west. 

Trees in tropical forests are dying at an increased rate, with consequences for biodiversity, carbon storage, and the global climate. While deforestation is the primary cause of forest loss, intact forests are also experiencing a rise in tree death. Drought, higher temperatures, and fires have been the leading suspects, but a new paper led by Evan Gora, a forest ecologist at Cary Institute of Ecosystem Studies, identifies an underappreciated threat: thunderstorms, which are becoming more frequent with climate change.

Forests, grasslands, and other natural areas around the world have access to about a quarter less nitrogen than previously estimated, according to a new study published today in Nature. Coauthored by Sarah Batterman, an ecologist at Cary Institute of Ecosystem Studies, findings have implications for natural climate solutions, as nitrogen is essential to plant growth and thus the removal of carbon from the atmosphere.

Elizabeth Cook explores how nature-based solutions can support cities in becoming more resilient and equitable in the face of climate change and rapid urbanization. Through this work, Cook also examines how people relate to the natural world.

Cary's Dave Strayer urges caution using biotechnology to re-introduce species into sometimes radically different ecosystems; the ecological effects could be large, and hard to predict and manage.

A lecture by Peter Kareiva, chief scientist for The Nature Conservancy (TNC). Kareiva talks about how to quantify nature's assets and how to move conservation from a special interest to the people's choice.

“Acquired tick resistance,” occurs when a person’s immune system learns to fight off ticks on its own after repeated bites. Can an anti-tick vaccine protect humans from tick-borne diseases?

Greta Keilman is a lab technician in the Stewart Merrill Lab, where she supports both lab-based experiments and fieldwork aimed at advancing our understanding of the causes and consequences of disease in freshwater ecosystems.

Water managers and state wildlife officials last year hoped the discovery of a microscopic zebra mussel larva in the Colorado River was a one-time event, not a sign of a larger problem lurking beneath the surface.

Getting blasted by a bolt from the heavens usually spells the end for trees, but some species not only survive these strikes, they thrive.

To understand how changing green spaces in cities impact plants, animals, and people, we’re studying three cities in the Hudson Valley — Kingston, Newburgh, and Poughkeepsie. These cities are developing greenways, or connected green spaces that can offer habitat and corridors for wildlife.

A study to assess whether publicly available data sources captured an increase in air pollution during the 2025 LA fires, how air quality changed over space and time, and how the trends differed between data sets.
