Polluted Waters Lead to Surge in Zooplankton Abundance, Alarming Ecosystem Shift
The researchers studied the types of tiny animals in the Northern Dvina River over 50 years. They found that there were 141 different species, with more copepods in recent years. The water quality affects the number and types of these animals, with more diversity in polluted areas. The amount of oxygen in the water is the main factor that determines where these tiny animals are found.
