What a nice site!
Information about – yes – Fauna Europaea. Works fast, quite clear to my opinion, nice taxonomic trees and maps – and a bunch of links to other on-line databases.
I was looking for a link to the Dutch taxa-database, the TWN-list, but it isn’t there. Perhaps because it’s in Dutch. At least what the phytoplankton concerns, it’s quite wondeful. When do they go international?
