While we are doing this, sampling many srecies over certain . pericds, it also gives us an opportunity to pull out a good deal of the ecological relationshins which are involved. In other aa words, this essentially is a long, large-scale laboratory tyre ef function, Cur area includes not tke entire Colunbia River watershe:
