Zebra mussels are one of the most pernicious invasive species in the United States having infested the Great Lakes in the 1980s and then having spread to 29 states by hitching rides on boats on inland waterways.
Author and award-winning ecologist Kurt Fausch has spent his career exploring threats to stream and river life. His new book, For the Love of Rivers, reflects on the deep significance of freshwaters to humanity and their ultimate fate in our future.
Freshwater ecologist Emma Rosi-Marshall explores how pharmaceutical drugs and personal care products are polluting our nation's rivers and streams—with consequences for sensitive aquatic life and drinking water supplies.
Increasing salt in our streams has been a concern at the Cary Institute for many years. Even in the relatively undeveloped watershed of the East Branch of Wappinger Creek, the salt levels have increased since 1985 when sampling began.
Dr. Weathers is co-Chair of the Global Lake Ecological Observatory Network (GLEON), a grassroots research network that conducts innovative science by sharing and interpreting high resolution sensor data to understand, predict and communicate the role and response of lakes in a changing global environment.
Carbon released from terrestrial ecosystems is an important source of organic matter in most streams, lakes and rivers. In the Hudson River there has been a doubling in concentration of dissolved organic carbon over the past 15 years.
Submersed aquatic vegetation (SAV) is an important habitat in the Hudson River. We have investigated a wide range of functions in SAV beds including maintenance of high dissolved oxygen, effects on suspended sediment, and habitat value.
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.
We have carried out a diversity of small and mesocosm-scale experiments, in conjunction with regionally distributed field sampling, to assess when the composition of stream benthic bacterial communities corresponds with differences in stream metabolic activities.
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.
