Dr. Gregor Hagedorn, Berlin, Germany.

Unfortunately, some activities had not been possible on Wikipedia itself. The work on identification tools and nature guides can therefore be found on several projects of biowikifarm.net.

Topics:
 * Mass extinction
 * Museum Technology
 * Identification technology
 * Sustainability

Two accounts: Earlier I also edited as G.Hagedorn (and German Wikipediade:User:G.Hagedorn, Commons, Meta, WikiSpecies) because this current account was available only on some wikis, but not for global single-sign-in (without any edits here or in any other wiki known to me). This being resolved, I now prefer the account with the full name. I have never voted in parallel with both accounts and will never do so. G.Hagedorn is essentially dormant now.
