Q. I'm looking for a few journal articles on salmon. I'm trying to find out what kind of sediment is best spawning.

There are a couple of article databases that might be useful for this search.  I would recommend checking out the list of databases here: http://libguides.wwu.edu/environmental_studies_databases.  Also on that page is a profile for our librarian who specializes in Environmental Studies, Rob Lopresti.  He may know of some other resources that would be useful for this topic if you wanted to contact him.

Searching in the Biological and Medical Sciences database for Salmon and Spawn and Geomorphology had the following results that might be useful (note: the links may not work in this email-- in this database the best way to get these articles is to replicate the search)

• Hierarchical Physical Controls on Salmonid Spawning Location and Timing
• Redd site selection and spawning habitat use by fall chinook salmon: The importance of geomorphic features in large rivers
• Multi-scale Dynamics of Surface and Subsurface Processes and Effects on the Hydrochemistry and Hydroecology of a MontaneSalmon Spawning Stream
