Day 2: Lotic
Stream ecology is an interdisciplinary area of science that brings together biology (especially ecology), and the physical (earth) sciences such as hydrology.

Here is a 4-part mini course from the American Museum of Natural History and the Cary Institute of Ecosystem Studies, focusing on river ecology, and in particular the problem of the invasive zebra mussel in the Hudson River. Alternate the readings and the short videos as you move through this minicourse.

As with Day 1, focus your observations on a stream of any size today or on any other observation day, if that is possible near where you live or where you can travel. These flowing fingers of water are called “streams” in general, although that word is also used for smaller ones. Feel free to visit anything from a tiny creek that might only flow at some times of year, to a huge river that carries enormous amounts of water across large stretches of a continent. Be careful when you conduct your observations—rivers can be dangerous! Safely enjoy the stream, its movements, the shape of the shoreline and its associated life, and any other aspects of the stream and its interaction with the surrounding areas.
