Ecological Monitoring

Scientists research biology, botany, microbiology, habitat, climate, water quality, and other fields to achieve a comprehensive view of ecosystems and their health. Ecosystems can be easily stressed by human activities, climate change, sediment, nutrients, contaminants, and many other variables. Ecosystem monitoring is critical to ecosystem health and answers important questions about the...

Pesticides

About 1 billion pounds of conventional pesticides are used each year in the United States to control weeds, insects, and other pests. The use of pesticides has resulted in a range of benefits, including increased food production and reduction of insect-borne disease, but also raises questions about possible adverse effects on the environment, including water quality. The...
