FISH/RANGE 530
STREAM ECOLOGY

This course focuses on the integrative principles of stream and groundwater ecology as a means of understanding the natural history and ecology of running waters. 

Course Objectives:

1.  To understand the physical, chemical, and biological organization of streams.

2.  To evaluate current theory in stream, groundwater and watershed ecology.

3.     To provide a watershed perspective for studying flowing waters and for interpreting the effects of man's activities on streams and rivers.

4.     To develop laboratory and field skills for conducting stream research.

Course Content:  The course consists of several major segments:

1.  Geomorphology, hydrology, and hydraulics of mountain and lowland streams.

2.  Water chemistry and nutrient cycling in streams and rivers.

3.  Structure of stream biota, including algae, heterotrophic microorganisms, meiofauna, benthic invertebrates, and fish.

4.  Ecosystem processes, including primary production, secondary production, decomposition, and organic matter retention in streams.

5.  Trophic interactions among the biota, such as herbivory, predation, and food-web dynamics.

6.  Theoretical advancements in stream and groundwater ecology, such as the river continuum concept, nutrient spiraling, hyporheos & flood-pulse concept.

7.  Management issues for streams and watersheds, such as land use, stream restoration, and river impoundment.

Course Structure:

Three classes per week (MWF 9:30-10:20).  Lectures on Monday/Wednesday with student-led discussions of research papers, etc. on Friday. There will be three field trips (Sept 6, 20 & Oct 4) to local streams & rivers, during which we will conduct physical, chemical, and biological measurements of streams, including sampling of algae and invertebrates.
