A short list of Institute findings on the Hudson River includes:

	Water chestnut, an invasive aquatic plant, is abundant on the Hudson River. Drs. Nina M. Caraco, and Jonathan J. Cole have found that it creates hundreds of acres of oxygen-free water during the summer, diminishing the habitat value of invaded areas for fish and other animals.
	Drs. David L. Strayer and Stuart E. G. Findlay are investigating the role that water celery, a native submerged aquatic plant, plays in the Hudson River. Thus far, they have found that the plants oxygenate the water column and provide valuable habitat for fish and other aquatic animals. With a preference for shallow water, plant beds are easily damaged by boating activity.
	Invasive zebra mussels are abundant in the Hudson River. A team of Institute scientists, including Drs. David L. Strayer, Jonathan J. Cole, Nina M. Caraco, and Stuart E. G. Findlay, has found that the bivalves have significantly altered the ecosystem's food web, causing a change in resident fish populations.
	Research by Drs. Jonathan J. Cole and Stuart E. G. Findlay has found that river bacterial growth greatly exceeds phytoplankton growth, indicating that bacterial growth is fueled by watershed inputs.
	Findings by Drs. Jonathan J. Cole and Nina M. Caraco have revealed that phytoplankton production, which fuels much of the Hudson's food web, is limited by light rather than nutrients. Additionally, freshwater flow exerts a strong control on plankton populations.
	Institute research is shedding new light on how wetlands contribute to the Hudson River ecosystem. In addition maintaining water quality, wetlands provide habitat for fish. Dr Stuart E. G. Findlay and colleagues are investigating how railway embankments and invasive species impact wetland function.
	Drs. Jonathan J. Cole and Nina M. Caraco with colleagues at Yale (Peter Raymond), VIMS (Jim Bauer) and U.Mass (Steve Petsch) have discovered that the Hudson River food web is supported by ancient terrestrial carbon. The perch you catch next week could be composed of carbon that was converted to organic matter by photosynthesis well before the time of Henry Hudson's voyage.
