Cera A., Mendes J., Cortada À. & Gómez-Bolea A. (2022): Cover of Ramalina species as an indicator of habitat quality in threatened coastal woodlands - Bryologist, 125(3): 424–432

Coastal forests in the Mediterranean area are threatened habitats due to intense human influence. In the context of global change, a rapid tool is needed for the evaluation of habitat quality in woodlands by calculating lichen cover on twigs rather than weight biomass. We selected epiphytic Ramalina species as indicators of habitat quality and evaluated them in threatened woodlands dominated by Olea europea var. sylvestris on the island of Menorca, a UNESCO Biosphere Reserve in the Mediterranean … URL EndNote Read more...

Varrica D., Lo Medico F. & Alaimo M.G. (2022): Air quality assessment by the determination of trace elements in lichens (Xanthoria calcicola) in an industrial area (Sicily, Italy) - International Journal of Environmental Research and Public Health, 19(15): 9746 [15 p.]

This study provides data on variation in the content of metals and metalloids measured in the lichens (Xanthoria calcicola Oxner) collected in the Syracusan petrochemical complex (Sicily, Italy) which is considered one of the largest in Europe. Concentrations of eighteen trace elements measured in the lichens that were collected from 49 different points were analyzed using an inductively coupled plasma (ICP-MS) device. The concentrations of the typical elements of industrial emissions (As, Cr, Ni, … URL EndNote Read more...

Ai M., Li L.J., Worthy F.R., Yin A.C., Zhong Q.Y., Wang S.Q., Wang L.S. & Wang X.Y. (2022): Taxonomy of Buellia epigaea-group (Caliciales, Caliciaceae), revealing a new species and two new records from China - MycoKeys, 92: 45–62

During the Second Tibetan Plateau Scientific Expedition and Research Program, we discovered that white terricolous lichenized fungal species of Buellia De Not. were widely distributed across the Tibetan Plateau. After examining their morphology, chemistry and phylogeny, we describe Buellia alpina Xin Y. Wang & Li S. Wang, sp. nov. as new to science. It is present in alpine meadows, and is characterized by its effigurate thallus, distinct linear marginal lobes, cover of thick white pruina … URL EndNote Read more...

Garrido-Huéscar E., González-Burgos E., Kirika P.M., Boustie J., Ferron S., Gómez-Serranillos M.P., Lumbsch H.T. & Divakar P.K. (2022): A new cryptic lineage in Parmeliaceae (Ascomycota) with pharmacological properties - Journal of Fungi, 8(8): 826 [12 p.]

We used molecular data to address species delimitation in a species complex of the parmelioid genus Canoparmelia and compare the pharmacological properties of the two clades identified. We used HPLC_DAD_MS chromatography to identify and quantify the secondary substances and used a concatenated data set of three ribosomal markers to infer phylogenetic relationships. Some historical herbarium specimens were also examined. We found two groups that showed distinct pharmacological properties. The phylogenetic … URL EndNote Read more...

Barreno E., Muggia L., Chiva S., Molins A., Bordenave C., García-Breijo F. & Moya P. (2022): Trebouxia lynnae sp. nov. (former Trebouxia sp. TR9): Biology and biogeography of an epitome lichen symbiotic microalga - Biology, 11(8): 1196 [19 p.]

Two microalgal species, Trebouxia jamesii and Trebouxia sp. TR9, were detected as the main photobionts coexisting in the thalli of the lichen Ramalina farinacea. Trebouxia sp. TR9 emerged as a new taxon in lichen symbioses and was successfully isolated and propagated in in vitro culture and thoroughly investigated. Several years of research have confirmed the taxon Trebouxia sp. TR9 to be a model/reference organism for studying mycobiont–photobiont association patterns in lichen symbioses.

Koelemeijer I.A., Ehrlén J., Jönsson M., De Frenne P., Berg P., Andersson J., Weibull H. & Hylander K. (2022): Interactive efects of drought and edge exposure on old‑growth forest understory species - Landscape Ecology, 37: 1839–1853

Context: Both climatic extremes and land-use change constitute severe threats to biodiversity, but their interactive effects remain poorly understood. In forest ecosystems, the effects of climatic extremes can be exacerbated at forest edges. Objectives: We explored the hypothesis that an extreme summer drought reduced the richness and coverage of old-growth forest species, particularly in forest patches with high edge exposure. Methods: Using a high-resolution spatially explicit precipitation … URL EndNote Read more...

Erlandsson R., Bjerke J.W., Finne E.A., Myneni R.B., Piao S., Wang X., Virtanen T., Räsänen A., Kumpula T., Kolari T.H.M., Tahvanainen T. & Tømmervik H. (2022): An artificial intelligence approach to remotely assess pale lichen biomass - Remote Sensing of Environment, 280: 113201 [14 p.]

Although generally given little attention in vegetation studies, ground-dwelling (terricolous) lichens are major contributors to overall carbon and nitrogen cycling, albedo, biodiversity and biomass in many high-latitude ecosystems. Changes in biomass of mat-forming pale lichens have the potential to affect vegetation, fauna, climate and human activities including reindeer husbandry. Lichens have a complex spectral signature and terricolous lichens have limited growth height, often growing … URL EndNote Read more...

Di Biase L., Di Lisio P., Pace L., Arrizza L. & Fattorini S. (2022): Use of lichens to evaluate the impact of post-earthquake reconstruction activities on air quality: A case study from the city of L’Aquila - Biology, 11(8): 1199 [14 p.]

Lichens are widely used as bioindicators of air quality because of their ability to absorb chemical pollutants. We used the Lichen Diversity Value (LDV) index to assess the effects of the urban reconstruction activities in the city of L’Aquila ten years after the 2009 earthquake on air quality. Sampling was conducted from the city centre (still mostly under reconstruction and closed to traffic) to suburban areas (where reconstruction is minimal). We tested if the LDV index varied with distance … URL EndNote Read more...

Firdous Q., Habib K., Khalid A.N. & Aptroot A. (2022): Physcia vitii Nadv. new to south Asia - molecular data - Pakistan Journal of Botany, 54(6): 2341–2345

A species in the genus Physcia was collected from dry temperate ecozones of Pakistan. The critical morpho-anatomical comparison to the known species of the genus revealed it to be P. vitii. Its existence here indicates that it is first report from South Asia and also here been described for the first time on the basis of ITS marker. A taxonomic treatment including a description based on the newly collected material is provided along with a molecular phylogenetic analysis. Key words: New record, … URL EndNote Read more...

Fernández-Prado N., Prieto M., Martínez I. & Aragón G. (2022): Líquenes epífitos de los Tepuyes de la cuenca alta del río Nangaritza, cordillera del Cóndor (Ecuador) - Caldasia, 44(1): 108–118

Tropics harbour the greatest biodiversity in the planet but are still largely unknown. Among these remote areas, there are the Tepuyes of Nangaritza Valley, in the Zamora Chinchipe province, southeastern Ecuador. They constitute isolated mountainous systems with great biological importance and high levels of endemicity. Therefore, the main objective of this study was the elaboration of the first catalogue of epiphytic lichens from several Tepuyes in the Nangaritza Valley. Two expeditions were carried out … URL EndNote Read more...
