This interface generates lists of species and statistics computed for several biological and ecological parameters associated to each infrageneric taxon. The query is complex: the operator must select whether to work on the whole study area or on one of its 4 Regions, then a phytoclimatic area, and then (optionally) any combination of ecological and biological parameters. Queries where only a geographic area is selected just return its hitherto known lichen taxa, occurring in the Dolichens database. Indicator values and other ecological parameters can be combined in such a way as to reconstruct different ecological scenarios, thereby obtaining "virtual releves", which may even simulate presence-absence data in a single vegetation plot. The predictivity of "virtual releves" was tested by a comparison with real data by Nimis & Martellos (2001), and proved to be high. Species lists produced by this interface might be of interest for several potential users.
