Researchers Find Broad Impacts from Lake Trout Invasion

Timothy Knepp, U.S. Fish and Wildlife Service

Introduction of non-native lake trout in Yellowstone Lake has affected organisms from the microscopic level in the lake to large animals in the region, according to newly published research.

Zooplankton, cutthroat trout, river otters, osprey, bald eagles, bears and, likely, elk are among the creatures whose numbers, diet and behavior have been altered as a result of the presence of the invasive fish, says an article that appears today (March 20) in the scientific journal Science Advances.
