Dr. Strayer's research is focused on the distribution and roles of freshwater invertebrates. He is currently working on the ecology of the Hudson River and on understanding the controls on distribution and abundance of pearly mussels. He is co-author of The Pearly Mussels of New York State, a comprehensive book on unionids, a diverse and endangered group of animals. In addition, Dr. Strayer has developed A Beginner's Key to Freshwater Meiofauna to accompany Palmer, M. A., D. L. Strayer, and S. D. Rundle. 2005. Meiofauna. In: F. R. Hauer and G. A. Lamberti (eds.). Stream ecology: field and laboratory exercises.
Beds of water celery (Vallisneria americana) and other plants are widespread in the Hudson River, and play several important ecological functions. These beds contain a diverse invertebrate community, which may serve as a major source of food to the river's fish.
What controls the distribution and abundance of pearly mussels, a species-rich and highly endangered group of animals in eastern North America?
Zebra mussels appeared in the Hudson in 1991 and fundamentally transformed the ecosystem. The zebra mussel invasion is linked to losses of native mussels and changes in the fish community.
For three decades, our scientists have been researching the Hudson River ecosystem– from the way shoreline development impacts water quality to how invasive species influence resident plants and animals. As a result, the Hudson is the most scientifically scrutinized river in the world.
Dave Strayer, a freshwater ecologist at the Cary Institute,discusses the organization’s Hudson River Research Program, the river’s environmental recovery, and challenges that need to be met.
A short documentary by the American Museum of Natural History. The video highlights zebra mussels in the Hudson River and the Cary research that closely analyzed the river before, during and after the invasion.
In the late 1800s, mute swans were brought from Europe to the eastern U.S. to enhance the beauty of ponds on private estates.
In the 1960s, grass carp were brought to the U.S. from Asia to control weeds in southern fish-farming operations. Unfortunately, like so many other exotics, these fish escaped into the wild, and have been moving northward.
As a child, I remember looking with some fascination at barnacles on the piers in a Cape Cod harbor, and reading about how their growth on the bottoms of boats so slowed their progress in the water that dry-docking for barnacle removal was a common practice
In a win for New York State’s natural areas, new regulations have gone into effect banning a long list of plants and animals that have plagued our fields, forests, and freshwaters.
In the late 1960s, our country’s fresh waters were in crisis. Ohio’s Cuyahoga River and the Detroit’s Rouge River were prone to fires. Time Magazine declared Lake Erie dead.
Tiny blue-green algae brought Toledo, Ohio’s municipal water system to a halt this summer. Toxic blooms left residents scrambling for bottled water to meet their drinking, cooking, and washing needs.
