Terricolous lichens in the glacier forefield of the Morteratsch glacier (Eastern Alps, Graubünden, Switzerland)
No full textThree sampling sites were established at increasing distance from the Morteratsch glacier to investigate lichen communities on soil in the glacier forefield. The survey yielded 13 lichen species and one lichenicolous fungus. Peltigera extenuata (NYL. ex VAIN.) LOJKA (Peltigerales) is new to the canton of Graubünden

The genus Cladonia in western Liguria (Northern Italy)
No full textThe genus Cladonia (Cladoniaceae, Lecanorales, lichenized Ascomycota) has been surveyed in 44 sites in the province
of Imperia in western Liguria. Of 36 taxa recorded, Cladonia dimorpha and C. pseudopityrea are new to northern
Italy, and C. cryptochlorophaea, C. pleurota, C. polydactyla and C. rei are new to Liguria; interesting are also records
provided for C. arbuscula, C. incrassata and C. mediterranea. The most widespread species are C. chlorophaea, C.
pyxidata, C. ramulosa and C. rangiformis. Data on ecology and chemistry of the species are given
Lichen-forming and lichenicolous fungi new to Kazakhstan
No full textAlthough there is a published lichen flora of Kazakhstan, the diversity of lichen-forming and lichenicolous fungi of this country is incompletely known. Here we publish records of 41 species of lichens and 2 species of lichenicolous fungi for the first time from Kazakhstan. All collections are from the Kazakh Altai and the Saur Mountains, East Kazakhstan. Caloplaca monacensis, Immersaria iranica, Lepraria elobata, L. rigidula and Parmelina pastillifera are new for the wider surroundings of Kazakhstan, as they have neither been found in Central Asia so far, nor in southern Siberia. Several species are new to Central Asia, but were already known from the nearby Siberia
Species diversity of lichens in the sacred groves of Epirus (Greece).
No full textThe sacred groves in the mountains of Epirus in NW Greece have been established during the Ottoman period and
consist of locally adapted systems set apart from the surrounding intensively managed, anthropogenic landscape. We
inventoried eight sacred groves and compared them with nearby control (managed) forests. In total, 166 taxa of lichens
and 5 of lichenicolous fungi were recorded. The most common lichen species were Anaptychia ciliaris, Phlyctis
argena and Lecidella elaeochroma. Seven species are new for Greece: Calicium quercinum, Chaenotheca ferruginea,
Chaenotheca trichialis, Chaenothecopsis nana, Leptogium hibernicum, Parvoplaca nigroblastidiata and Rinodina
orculata. The sacred groves appeared not very different from the control forests; more pronounced differences were
observed between deciduous oak evergreen oak and pine forests. Localities characterized by deciduous oak forest
hosted the highest number of taxa belonging to the order Peltigerales, the most frequent were: Nephroma laevigatum,
Collema subflaccidum, Leptogium lichenoides and Lobaria pulmonaria, but also rare species such as Polychidium
muscicola, Koerberia biformis and Degelia atlantica were recorded

Assembly patterns of soil-dwelling lichens after glacier retreat in the European Alps
No full textAim: To assess the spatial-temporal dynamics of primary succession following deglaciation in soil-dwelling lichen communities. Location: European Alps (Austria, Switzerland and Italy). Methods: Five glacier forelands subjected to relevant glacier retreat during the last century were investigated. In each glacier foreland, three successional stages were selected at increasing distance from the glacier, corresponding to a gradient of time since deglaciation between 25 and 160 years. In each successional stage, soil-dwelling lichens were surveyed within five 1 × 1 m plots. In addition to a classical ecological framework, based on species richness and composition, we applied a functional approach to better elucidate community assembly mechanisms. Results: A positive relationship was found between species richness and time since deglaciation indicating that richer lichen communities can be found at increasing terrain ageing. This pattern was associated with compositional shifts, suggesting that different community assemblages can be found along the successional stages. The analysis of β-diversity revealed a significant nested pattern of species assemblages along the gradient (i.e. earlier successional stages hosted a subset of the species already established in older successional stages), while the turnover component was less relevant. Considering functional groups, we found contrasting patterns in relation to time since deglaciation: the incidence of species with a cyanobacterial photobiont and those reproducing by spores decreased, while that of species reproducing by vegetative propagules increased. Main conclusions: This study reveals that community assembly patterns of soil-dwelling lichens in alpine glacier forelands are ruled by mechanisms of directional species accumulation and trait selection that involve a trade-off between different functional strategies. Functional traits that reflect the dispersal and adaptation capability of the species underpin the colonization success of soil-dwelling lichens in glacier forelands
