Understanding of nitrogen cycling in lichens of the genus Cladonia by NMR metabolomics

Manuela Mandrone, Ilaria Chiocchio, Gabriele Gheza, Juri Nascimbene et autres

Understanding nitrogen dynamics in lichens, while providing insights into lichen physiology and symbiosis, can also be important in assessing the impact of human footprint on ecosystems. In this work, we studied four species of Cladonia Hill. ( C. foliacea, C. polycarpoides , …

Range Shift and Climatic Refugia for Alpine Lichens Under Climate Change

Luana Francesconi, Michele Di Musciano, Matteo Conti, Luca Di Nuzzo et autres

ABSTRACT Aim The mountain biodiversity is highly threatened by climate change, with many species facing habitat reduction and/or local extinction. Poikilohydric organisms like lichens are extremely sensitive to environmental conditions and changes. A comprehensive overview of the impact of climate change on …

Towards a better knowledge and conservation of cryptic macrolichens in Italy: a revision of the genus Cetrelia (Parmeliaceae, Lecanorales, lichenized Ascomycota)

Gabriele Gheza, Chiara Vallese, Luca Di Nuzzo, Simona Corneti et autres

Cryptic species are a challenge for conservation since their ambiguous recognition can hinder a reliable evaluation of their distribution and ecology, thus affecting the assessment of their conservation status. Cetrelia W.L. Culb. & C.F. Culb. is a foliose chlorolichen genus with four …

Bedrock-Dependent Effects of Climate Change on Terricolous Lichens Along Elevational Gradients in the Alps

Chiara Vallese, Luca Di Nuzzo, Luana Francesconi, Paolo Giordani et autres

In this study, we focused on the bedrock-dependent effects of climate change on terricolous lichen communities along elevational gradients in the Alps. In particular, we contrasted between carbonatic and siliceous bedrock, hypothesizing more favourable conditions on siliceous than on carbonatic bedrock, where …

Bryophyte, lichen, and vascular plant communities of badland grasslands show weak cross-taxon congruence but high local uniqueness in biancana pediments

Emanuele Fanfarillo, Stefano Loppi, Claudia Angiolini, Giovanni Bacaro et autres

Cross-taxon congruence, i.e., using certain taxonomic groups as surrogates for others, is receiving growing interest since it may allow decreasing efforts in biodiversity studies. In this work, we investigated the patterns of cross-taxon congruence in species richness and composition between communities of …

The Dolichens database: the lichen biota of the Dolomites

Luana Francesconi, Matteo Conti, Gabriele Gheza, Stefano Martellos et autres

The Dolichens project provides the first dynamic inventory of the lichens of the Dolomites (Eastern Alps, Italy). Occurrence records were retrieved from published and grey literature, reviewed herbaria, unpublished records collected by the authors, and new sampling campaigns, covering a period from …

Lobaria pulmonaria (L.) Hoffm.: The Multifaceted Suitability of the Lung Lichen to Monitor Forest Ecosystems

Sonia Ravera, Renato Benesperi, Elisabetta Bianchi, Giorgio Brunialti et autres

Lobaria pulmonaria (L.) Hoffm. is a tripartite, broad-lobed foliose lichen usually found on bark and on epiphytic and epilithic mosses in humid forests. Currently, the species is threatened in most European countries because of its sensitivity to environmental alterations. In this paper, …

Species–area relationship in lichens tested in protected areas across Italy

Gabriele Gheza, Luca Di Nuzzo, Paolo Giordani, Alessandro Chiarucci et autres

Abstract The species–area relationship (SAR) states that species richness increases with the increase of the sampled area, although other factors can influence the pattern. SARs have been tested on many different organisms, but only rarely on lichens. We aimed to test the …

Dolichens project: the lichen biota of the Dolomites

Luana Francesconi, Matteo Conti, Gabriele Gheza, Stefano Martellos et autres

Launched in 2022 the Dolichens project aims to assemble an inventory of the lichens reported from the Dolomite area since the 19th century. Data of lichen occurrences have been retrieved and aggregated from herbaria, literature, unpublished data, and new sampling campaigns.
