N2  - Hot spots are characterized by the occurrence of „hot“ species, rare, endangered, phytogeographically (for example highly disjunct) or ecologically interesting species (for example heavy metal species). The Apuanian Alps (ital. Alpi Apuani) are a place of extraordinary botanical and also bryological interest. Although situated far from the west coast of Europe, many atlantic species are found there, which have isolated occurrences and show up next in Asturias, Macaronesia. Ireland or Scotland. Representative of the oceanic element in the bryoflora are Dumortiera hirsuta, Lejeunea lamacerina, Lophocolea fragrans, Plagiochila exigua, P. bifaria, Saccogyna viticulosa, Harpalejeunea ovata and Marchesinia mackaii, supplemented by ferns such as Trichomanes speciosum and Hymenophyllum tunbrigense (Cortini-Pedrotti et al. 1992). Reasons for the presence of such species in Italy are the extraordinary climatic conditions. Situated directly along the Meditrerranean Sea, the climate is mild and due to depressions in the gulf of Genova, the rain is caught by the mountains resulting in a high precipitation of about 1400 at the foot of the region and more than 3000 mm in the summit region. This does, however, not explain whether these species are relics from the Tertiary or dispersed from the W-coast of Europe after the Pleistocene glaciations.
