<h3>What is a Ecologist?</h3>
In the 1990s, the reintroduction of wolves to Yellowstone National Park garnered widespread media attention and significantly increased the park's biodiversity. Unfortunately, the spread of exotic species like zebra mussels, Kudzu vines, and Burmese pythons in other regions of the United States more than offsets this success for native ecology.
The diverse roles that different species play in their communities make changes to those ecosystems very disruptive. Ecologists can aid us in making better decisions that reduce the effects of our actions on other species and the world by deepening our understanding of how nature functions.
