Similarly to other Mediterranean regions, Italy is expected to experience dramatic climatic changes in the coming decades. Do to their poikilohydric nature, lichens are among the most sensitive ...organisms to climate change and species requiring temperate-humid conditions may rapidly decline in Italy, such in the case of the epiphytic Lobaria species that are confined to humid forests. Our study, based on ecological niche modelling of occurrence data of three Lobaria species, revealed that in the next decades climate change will impact their distribution range across Italy, predicting a steep gradient of increasing range loss across time slices. Lobaria species are therefore facing a high extinction risk associated with reduction of their range. The current patterns indicate that only L. pulmonaria still has a continuous distribution across Italy, with potential contact between Apennine and Alpine populations. This situation is consistent with the wider climatic niche of this species, still offering a major opportunity for its successful long-term conservation. Results (a) support the inclusion of the three Lobaria species in European conservation policies, such as the Habitat Directive, and (b) warn against an over-estimation of the indicator power of single flagship species to establish conservation priorities for lichens, indicating that even lichens with peculiar and similar climatic envelopes may fail to co-occur within a given forest stand. A multiple indicator approach could provide more useful tools for a community-based conservation strategy for epiphytes.

This paper reports data on distribution of Petalophyllum ralfsii in Calabria (S Italy). Investigations conducted from 2016 to 2019 permitted to outline an updated and accurate overview on the number ...and size of the populations of the species in the region. New findings were recorded, while some known locations were not confirmed. The size of each population was measured by direct counting of thalli or by sampling with plots, enabling to have a reliable estimate of the species density. Analysis of data gives also important information on the ecology and dynamism of the species.
Calabria, the southernmost tip of the Italian Peninsula, is a biogeographically very interesting region for lichenologists, characterised by the abundance of oceanic and suboceanic species with ...subtropical affinities, but also by the presence of the southernmost outposts of several boreal species on the highest peaks. The lichen biota of Calabria, which began to be intensively studied only from the 1980s, hosts more than 1000 infrageneric taxa. The lichen herbarium of the Botanical Garden of the University of Calabria (CLU) is the most relevant lichen collection from this region. It was established in 1985 and it presently includes 16926 specimens, most of which were collected in Calabria, although there are also several specimens from other parts of Italy and from abroad.
This dataset contains 16926 records of lichens for a total of 1316 species. Of the 15219 georeferenced specimens, 10254 were collected in Calabria, while 4965 in other administrative regions of Italy. The dataset is available through GBIF, as well as in ITALIC, the Information System of Italian Lichens.
A phytosociological analysis of Tarsia Lake Regional Nature Reserve was carried out within a research project dealing with the vegetation of southern Italian wetlands. Twenty-four plant communities ...(19 associations and five communities not yet assigned to formal rank) were attributed to 17 alliances, 14 orders, and 11 classes. Most associations resulted as common in the Mediterranean area; however, as a response to the peculiarity of the local climatic and edaphic factors, some phytocoenoses were found as typical throughout central Europe but not observed in southern Italy, yet. Currently, this area is preserving a considerably interesting flora and vegetation for both naturalistic and phytogeographic reasons. Therefore, an appropriate monitoring and protection plan is needed in order to counteract the ongoing severe anthropogenic pressure.
