Johansson N.R., Kaasalainen U. & Rikkinen J. (2021): Woodpeckers can act as dispersal vectors for fungi, plants, and microorganisms, Ecology and Evolution, 11(12): 7154–7163

Bird‐mediated dispersal is presumed to be important in the dissemination of many different types of organisms, but concrete evidence remains scarce. This is especially true for biota producing microscopic propagules. Tree‐dwelling birds, such as woodpeckers, would seem to represent ideal dispersal vectors for organisms growing on standing tree trunks such as epiphytic lichens and fungi. Here, we utilize bird natural history collections as a novel source of data for studying dispersal ecology … Read more...

Stark S., Ylänne H. & Kumpula J. (2021): Recent changes in mountain birch forest structure and understory vegetation depend on the seasonal timing of reindeer grazing, Journal of Applied Ecology, 58(5): 941–952

Subarctic forest‐tundra ecotones dominated by mountain birch (Betula pubescens ssp. czerepanovii) are an important habitat for semi‐domestic reindeer Rangifer tarandus. The seasonal timing of reindeer grazing may direct vegetation trajectories in these systems, because in the summer ranges, mountain birches are subjected to browsing, while in the winter ranges, reindeer feed on understorey vegetation and arboreal lichens but leave the mountain birches intact. Based on earlier research, we predicted … Read more...

Mitchell R.L., Strullu-Derrien C., Sykes D., Pressel S., Duckett J.G. & Kenrick P. (2021): Cryptogamic ground covers as analogues for early terrestrial biospheres: Initiation and evolution of biologically mediated proto-soils, Geobiology, 19: 292–306

Modern cryptogamic ground covers (CGCs), comprising assemblages of bryophytes (hornworts, liverworts, mosses), fungi, bacteria, lichens and algae, are thought to resemble early divergent terrestrial communities. However, limited in situ plant and other fossils in the rock record, and a lack of CGC-like soils reported in the pre-Silurian sedimentological record, have hindered understanding of the structure, composition and interactions within the earliest CGCs. A key question is how the earliest CGC-like … Read more...

Zhong Q., Zhang Y., Wang X., Timdal E., Gong H., Wang Z. & Wang L. (2021): Phaeorrhiza (Physciaceae), a new lichen genus record to China, Phytotaxa, 510(3): 228–238

The genus Phaeorrhiza is reported as new for the Chinese lichen biota, including the two species, Phaeorrhiza nimbosa (Fr.) H. Mayrhofer & Poelt and P. sareptana var. sphaerocarpa. (Tr. Fr.) H. Mayrhofer & Poelt. The genus grows on soil in alpine meadows, morphologically characterized by a squamulose to subfoliose thallus, rhizohyphae, and Beltraminia-type ascospores. P. nimbosa has cryptolecanorine to eulecanorine apothecia, while P. sareptana var. sphaerocarpa has lecideine apothecia. Descriptions, … Read more...

(2021): Fine-grain beta diversity of Palaearctic grassland vegetation, Journal of Vegetation Science, 32: e13045 [15 p.]

Questions: Which environmental factors influence fine-grain beta diversity of vegetation and do they vary among taxonomic groups? Location: Palaearctic biogeographic realm. Methods: We extracted 4,654 nested-plot series with at least four different grain sizes between 0.0001 m² and 1,024 m² from the GrassPlot database, covering a wide range of different grassland and other open habitat types. We derived extensive environmental and structural information for these series. For each series … Read more...

Cornet L., Magain N., Baurain D. & Lutzoni F. (2021): Exploring syntenic conservation across genomes for phylogenetic studies of organisms subjected to horizontal gene transfers: A case study with Cyanobacteria and cyanolichens, Molecular Phylogenetics and Evolution, 162: 107100 [18 p.]

Understanding the evolutionary history of symbiotic Cyanobacteria at a fine scale is essential to unveil patterns of associations with their hosts and factors driving their spatiotemporal interactions. As for bacteria in general, Horizontal Gene Transfers (HGT) are expected to be rampant throughout their evolution, which justified the use of single-locus phylogenies in macroevolutionary studies of these photoautotrophic bacteria. Genomic approaches have greatly increased the amount of molecular … Read more...

Gerasimova J., Ruthensteiner B. & Beck A. (2021): MicroCT as a useful tool for analysing the 3D structure of lichens and quantifying internal cephalodia in Lobaria pulmonaria, Applied Microbiology, 1(2): 189–200

High-resolution X-ray computer tomography (microCT) is a well-established technique to analyse three-dimensional microstructures in 3D non-destructive imaging. The non-destructive three-dimensional analysis of lichens is interesting for many reasons. The examination of hidden structural characteristics can, e.g., provide information on internal structural features (form and distribution of fungal-supporting tissue/hypha), gas-filled spaces within the thallus (important for gas exchange and, thus, … Read more...

Belguidoum A., Lograda T. & Ramdani M. (2021): Ability of metal trace elements accumulation by Lichens, Xanthoria parietina and Ramalina farinacea, in Megres area (Setif, Algeria), Acta Scientifica Naturalis, 8(1): 91–108

The accumulating ability of the atmospheric Metal Trace Elements (MTE) of two lichenic species thalli; Xanthoria parietina and Ramalina farinacea were evaluated in the region of Megres. The recorded concentrations of MTE (Fe, Cu, Mn, Cd, and Pb) were determined by atomic absorption spectrophotometry (AASF). The ability to accumulate MTE in X. parietina thalli is considerably greater than that of the fruticulous lichen R. farinacea in all stations studied. The general pattern of the elements accumulated … Read more...

Urbanavichene I.N. & Urbanavichus G.P. (2021): Additions to the lichen flora of the Kologriv Forest Reserve and Kostroma Region, Turczaninowia, 24(2): 28–41

As a result of determining the lichens collected in summer 2020 in the territory of the Kologriv Forest State Nature Reserve (Kostroma Region), 57 species (44 lichens, 5 non-lichenized and 8 lichenicolous fungi) new to the lichen flora of the Reserve were identified. Among them, 49 species and 17 genera ( Acrocordia, Allocalicium, Aca - rospora, Biatoridium, Catinaria, Cryptodiscus, Didymocyrtis, Fellhanera, Inoderma, Intralichen, Lichenoconium, Melaspileella, Rebentischia, Schismatomma, … Read more...

DeBolt A. (2021): Transplant success of Cladonia perforata (Florida perforate cladonia) at the Jupiter Inlet Lighthouse Outstanding Natural Area, Evansia, 38(2): 32–42

At the 120-acre Jupiter Inlet Lighthouse Outstanding Natural Area (ONA) located in southeast Florida, 30 Cladonia perforata thalli were translocated in 2009. Thalli were transplanted from an area with a large C. perforata population, where sand pine fuels had accumulated and were at risk of a fire, to an area that had either been recently burned, or where no fuel treatments were planned in the near future. There was no C. perforata at or near the four transplant recipient locations, which were … Read more...
