This file includes several reading assignments (also posted separately) about the following; river trophic levels, trophic relationships, the river continuum concept (Vannote et al., 1980), and two readings about pacific salmon. The salmon readings cover two aspects of salmon issues. The first issue describes the 6 main reasons for historical salmon decline including over fishing, hydroelectric projects, mining, etc. The second issue discussed is the issue of nutrient cycling due to salmon in Pacific watersheds. Finally, there is a vocabulary list and quiz added at the end of the packet related to the reading.
