I am looking to survey anyone willing to share their commonly used references for diatom identification. I would grateful if you could provide the habitat type you most commonly work on (e.g. marine plankton, freshwater streams, wet walls, etc...), and a list of the top 5 references you use. If you could provide an author(year), brief title of the work, and whether is it primary literature, a book, or a website.
Thank you in advance for your time.
Cheers;
David
