Course Objectives:

This course examines the ecology of rivers and streams from a watershed perspective, with emphasis on Pacific Northwest ecosystems.  Topics covered include hydrology, geomorphology, organic matter and trophic dynamics, biogeochemical cycles, aquatic insects, fish, riparian ecology and hyporheic processes.  The primary goal of this course is to provide students with an understanding of the physical and biological factors that shape the structure and dynamics of stream ecosystems, and the ways in which these factors are interrelated.  Another goal is to help students become informed, critical thinkers able to collect and analyse ecological data and to interpret the results of ecological studies.

 

Prerequisites:

ESCI or BIO 325;  ESCI 361 and 362.

 

Recommended Texts:

There is no required text for this course, although various references will be cited and/or recommended during lectures and labs.  Readings and other course materials can be downloaded from the ESCI 429/529 Blackboard site.

 

 

Field Trips:

In addition to weekly lab sessions, this course has two weekend field trips.  Attendance is mandatory for at least one of these trips.  During field trips, you should be prepared to be outside regardless of weather conditions.  If you do not have a good raincoat and waterproof boots, now would be a good time to invest in a set.  One field trip will require an overnight stay, for which you will be required to bring your own food and camping gear (e.g., sleeping bag, tent, backpack, water bottle).  Camping gear can be rented at reasonable rates from the WWU Outdoor Center.
