ADVANCED QUERY INTERFACE
This advanced query interface generates species and occurrence lists.
A combination of multiple parameters can be selected, and it is possible to filter the data by drawing a
rectangular area on an interactive map, where the outcomes will be visualized.
The query will generate a first table containing the list of species along with the associated taxonomic,
ecological, and biological information and a second table listing the different records for each species. Each
table can be downloaded in several formats.
Search details
No details
1 on very acid substrata, such as lignum and conifer
bark
2 on acid substrata, such on non-eutrophicated bark of
Quercus
3 on subacid to subneutral substrata (e.g. on bark of
Sambucus)
4 on slightly basic substrata, such as dust-covered
bark
5 on basic substrata, e.g. pure limestone
1 in very shaded situations, e.g. deep gorges, closed
evergreen forests
2 in shaded situations, such as on the northern side of
boles in close-canopied deciduous forests
3 in sites with plenty of diffuse light but scarce direct
solar irradiation, such as in rather open-canopied deciduous
woodlands
4 in sun-exposed sites, but avoiding extreme solar
irradiation
5 in sites with very high direct solar irradiation, e.g.
on the southern side of isolated boles
1 hygrophytic, in sites with a very high frequency of
fog
2 rather hygrophytic, intermediate between 1 and 2
3 mesophytic
4 xerophytic, but absent from extremely arid stands
5 very xerophytic
1 no eutrophication
2 very weak eutrophication
3 weak eutrophication
4 rather high eutrophication
5 very high eutrophication
This value points to the tendency of a lichen to occur in areas
with different degrees of human disturbance. It is expressed on
4 classes, as follows:
0 species which exclusively occur on old trees in
ancient, undisturbed forests. Contrary to the other values, this
one has been assigned to epiphytic species only, since it is
useful to point out indicators of long ecological continuity of
forests.
1 species occurring in natural or semi-natural
habitats
2 species occurring in moderately disturbed areas
(agricultural areas, small settlements etc.)
3 species occurring in heavily disturbed areas, incl.
large towns
1 eu-Mediterranean belt (potential vegetation: evergreen
Quercus ilex forest)
2 submediterranean belt (deciduous Quercus-Carpinus
forests)
3 montane belt (Fagus forests, marking treeline in the
Apennines)
4 Oroboreal belt of the Alps (natural Picea abies, and
Larix-Pinus cembra stands)
5 above treeline (both Alpine and oromediterranean)
