A networking resource devoted to biological soil crusts and the researchers who study them. We will provide a means for international scientists to communicate, share their research, share important news and announcements, ask questions and find collaborators. We will also provide a space for informal writing on research, opinion, and ideas (now seeking posters!).

European Geophysical Union 2012 - biocrusty sessions

The EGU schedule is now up. As promised here are the programs of the two sessions I know of which feature biological and physical soil crusts and dust (solely for space considerations,  I haven't listed some cool sounding talks form the same sessions but on very different topics). I imagine there are several other interesting sessions on, e.g. soil erosion, so check it out yourself....the program is huge and can be found here.  You'll note the sheer volume of material on biocrusts and related topics is huge here. It makes me think there ought to be an annual international crust conference.
