Unit of Microscopy and Chromatography (resp. Dr P. Clerc)

This unit is dedicated to the macroscopic, microscopic and chemical study of fungi (lichenized and non-lichenized), algae, hornworts, liverworts, mosses and ferns.

The material available consists principally of stereo-microscopes and light microscopes, photographing microscopes, a freeze-dry microtome and flat-bed chromatography equipment. A Leitz DC 300 digital camera coupled with an Imagic imagery system captures digital images with a deep field of view using a stereo-microscope or a light microscope.

The majority of the research carried out in the laboratory is based on the systematic studies of the lichens and bryophytes of Switzerland and of the two American continents. The results of these studies are essentially inventories of the biodiversity, tools for species identification and floras.

The laboratory of microscopy and chromatography accommodates Biology students from the Universities of Geneva and Neuchâtel within the framework of specialized courses, like "Systématique, phylogénie et écologie des lichens et des bryophytes" (University of Geneva, course 14B070) or "Exploitation des collections botaniques" (ex-Consultation d'herbier), (University of Geneva, course 14B021) as well as for Masters and Doctoral research projects.
