Chamizo S., Rodríguez-Caballero E., Moro M.J. & Cantón Y. (2021): Non-rainfall water inputs: A key water source for biocrust carbon fixation, Science of the Total Environment, 792: 148299 [6 p.]

• NRWI was measured with automated microlysimeters in different biocrust types. • NRWI deposition increasedwith greater biocrust development. • The effect of NRWI on biocrust CO2 fluxes depended on the main NRWI source. • Dew mainly stimulated biocrust photosynthesis, resulting in a net CO2 uptake. Links between water and carbon (C) cycles in drylands are strongly regulated by biocrusts. These widespread communities in the intershrub spaces of drylands are able to use non-rainfall … Read more...

Lopez-Ramirez M.R., Sancho L.G., de Vera J.P., Baqué M., Böttger U., Rabbow E., Martínez-Frías J. & de la Torre Noetzel R. (2021): Detection of new biohints on lichens with Raman spectroscopy after space- and Mars like conditions exposure: Mission Ground Reference (MGR) samples, Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 261: 120046 [8 p.]

First report of the Raman spectroscopy study of Mission Ground Reference (MGR) sample of Circinaria gyrosa. First use of the term ‘‘biohint” to describe what we are detecting in a more ethical way. Discussion based on Raman results from Space and Mars-like exposure conditions of Circinaria gyrosa. Dolomite together with whewellite have been identified in the medulla of Circinaria gyrosa. Prolonged exposure to UV radiation affects the photobiont and crystal structure … Read more...

Lagostina E., Andreev M., Dal Grande F., Grewe F., Lorenz A., Lumbsch H.T., Rozzi R., Ruprecht U., Sancho L.G., Søchting U., Scur M., Wirtz N. & Printzen C. (2021): Effects of dispersal strategy and migration history on genetic diversity and population structure of Antarctic lichens, Journal of Biogeography, 48(7): 1635–1653

Aim: The homogenisation of historically isolated gene pools has been recognised as one of the most serious conservation problems in the Antarctic. Lichens are the dominant components of terrestrial biotas in the Antarctic and in high mountain ranges of southern South America. We study the effects of dispersal strategy and migration history on their genetic structure to better understand the importance of these processes and their interplay in shaping population structure as well as their relevance … Read more...

Liu Y.-R., Eldridge D.J., Zeng X.-M., Wang J., Singh B.K. & Delgado‐Baquerizo M. (2021): Global diversity and ecological drivers of lichenised soil fungi, New Phytologist, 231(3): 1210–1219

Lichens play crucial roles in sustaining the functioning of terrestrial ecosystems; however, the diversity and ecological factors associated with lichenised soil fungi remain poorly understood. To address this knowledge gap, we used a global field survey including information on fungal sequences of topsoils from 235 terrestrial ecosystems. We identified 880 lichenised fungal phylotypes across nine biomes ranging from deserts to tropical forests. The diversity and proportion of lichenised soil fungi … Read more...

Ulus G. (2021): Antiangiogenic properties of lichen secondary metabolites, Phytotherapy Research, 35(6): 3046–3058

[Review] Lichens are symbiotic organisms which are composed fungi and algae and/or cyanobacteria. They produce a variety of characteristic secondary metabolites. Such substances have various biological properties including antimicrobial, antiviral, and antitumor activities. Angiogenesis, the growth of new vessels from pre-existing vessels, contributes to numerous diseases including cancer, arthritis, atherosclerosis, infectious, and immune disorders. Antiangiogenic therapy is a promising approach … Read more...

Molins A., Moya P., Muggia L. & Barreno E. (2021): Thallus growth stage and geographic origin shape microalgal diversity in Ramalina farinacea lichen holobionts, Journal of Phycology, 57(3): 975–987

Lichen symbioses are microecosystems hosting many other living organisms besides the two major lichen symbionts (i.e., lichenized fungi [the mycobiont] and green microalgae or cyanobacteria [the photobiont]). Recent investigations evidenced that other fungi, non‐photosynthetic bacteria, and microalgae co‐inhabit within the lichen thalli, but their diversity and their roles are still underinvestigated. Here we present an ad hoc stratified sampling design and in‐depth Illumina paired‐end … Read more...

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...

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...
