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.
The Changing Hudson Project (CHP) curriculum was developed by scientists and educators at the Cary Institute of Ecosystem Studies to help students understand how the Hudson River changes over time. By collaborating with area teachers, scientists, and management agencies, the curriculum has grown to include a wide range of topics that engage students with visualizations, readings, investigations, and actual scientific data.
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.
Presentation by David Strayer for an invasive species forum hosted at Cary on March 21, 2015.
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.
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 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.
Next time you go shopping, keep an eye out for the origins of the things you purchase. From kiwis grown in Chile to shirts made in Bangladesh – we are living in the age of the global marketplace.
Freshwater ecologist and author of The Hudson River Primer – The Ecology of an Iconic River Dave Strayer, discusses the positive effects of the federal Clean Water Act and other government regulations with Radio Rotary.
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.
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.
In rural areas, unpaved roads hold a certain charm. They restrict the volume and speed of traffic and, compared to their paved counterparts, are less expensive to build. But are they a greener alternative?
There were once three hundred species of mussels in the United States. They supplied food to Native Americans and people harvested them for pearls and for mother-of-pearl to make buttons. Now, hardly anyone eats freshwater mussels and buttons are mostly made of plastic.
Despite the fact many of us drink groundwater every day, and all of us eat food irrigated by groundwater, few people know where it comes from or how to protect it.
