Dominguez R.D., Stanton D., Peralta M. & Rodriguez J.M. (2022): Water regulation dynamics of lichens as functional traits could predict future climate change scenarios in an elevational gradient from Central Argentina - Bryologist, 125(3): 466–476

Mountain top environments are particularly vulnerable to climate change effects, given that biological organisms in these systems live at specific temperature conditions. The poikilohydric nature of lichens emphasizes variables like water holding capacity (WHC) and the hydrophobicity of the thallus to understand the species occupational patterns in altitudinal gradients and microsites. WHC and hydrophobicity were measured in 3 saxicolous species with 2 different morphologies in an elevational mountain … URL EndNote Read more...

Thiyagaraja V., Ertz D., Hyde K.D., Karunarathna S.C., To-Anun C. & Cheewangkoon R. (2022): Morphological and phylogenetic reassessment of Sclerococcum simplex from China - Phytotaxa, 559(2): 167–175

Sclerococcum is a species rich lichenicolous genus in Ascomycota. However, many species of Sclerococcum have been described based only on morphology. This study provides sequences for the large-subunit ribosomal RNA (LSU), internal transcribed spacer (ITS) and mitochondrial small-subunit ribosomal RNA (mtSSU) for the first time for Sclerococcum simplex, and the first geographical record of the genus from China. Phylogenetic analyses confirmed that S. simplex clustered within Sclerococcum … URL EndNote Read more...

Masumoto H. & Degawa Y. (2022): Cyphellostereum ushimanum sp. nov. (Hygrophoraceae, Agaricales) described from Amami‑Oshima Island (Kagoshima Prefecture, Ryukyu Islands), Japan, with ultrastructural observations of its Rhizonema photobiont flaments penetrated longitudinally by a central haustorium - Mycological Progress, 21: 167–179

We collected a resupinate fungus lichenized with flamentous Rhizonema cyanobacteria in Amami-Oshima Island, Japan. Microscopic observations and molecular phylogenetic analyses of both the basidioma and the lichenized thallus indicated afnities within Cyphellostereum, the frst record of this basidiomycete genus from Japan. Its unique combination of structural characters and ITS rDNA sequences suggests a new species, described here as C. ushimanum. Light and transmission electron microscopic … URL EndNote Read more...

Miller J.E.D., Weill A.M. & Villella J. (2022): Epiphytic macrolichen communities take decades to recover after high-severity wildfire in chaparral shrublands - Diversity and Distributions, 28: 454–462

Aim: Fire regimes are shifting globally due to climate change, land management practices and population growth, putting species at risk if they are unable to adapt to more frequent or severe wildfires. While many fire-adapted species may be able to accommodate some amount of change in fire regimes, fire-sensitive or late-successional species that colonize fire-prone ecosystems between wildfires may be especially vulnerable to more frequent or severe fires. Here, we seek to understand the … URL EndNote Read more...

Doležal J., Dančák M., Kučera J., Majeský L., Altman J., Řeháková K., Čapková K., Vondrák J., Fibich P. & Liancourt P. (2022): Fire, climate and biotic interactions shape diversity patterns along an Afrotropical elevation gradient - Journal of Biogeography, 49: 1248–1259

Aim: Untangling multiple drivers influencing biodiversity along elevation gradients is necessary for predicting the consequences of climate change on mountain communities. We examine the direct and indirect effects of macroclimate, edaphic conditions, fire frequency and putative biotic interactions on species richness and abundance of co-occurring primary producers on Mount Cameroon. Location: Mount Cameroon, Cameroon. Taxon: vascular plants, bryophytes and lichens, and soil microbial phototrophs. Methods: … URL EndNote Read more...

Miranda-González R., Epitacio-Joaquin G., Tehler A., Téllez N.S. & Herrera-Campos M.A. (2022): Roccella ramitumidula (Roccellaceae), a new species from the tropical dry forest of Mexico - Bryologist, 125(3): 477–484

The new species Roccella ramitumidula is described from a tropical dry forest in the Pacific Coast of Mexico. The new species is characterized by fertile thalli, saxicolous habit, irregularly swollen branches and erythrin and lecanoric acid as lichen products. It differs from R. decipiens by its narrower and longer ascospores, irregularly swollen branches, uneven surface, and smaller branches. Sequences of the genetic markers ITS, nuLSU and RPB2 from the new species were added to a phylogenetic … URL EndNote Read more...

Lynikienė J., Gedminas A., Marčiulynas A., Marčiulynienė D. & Menkis A. (2022): Can Larix sp. Mill. provide suitable habitats for insects and lichens associated with stems of Picea abies (L.) H. Karst. in northern Europe? - Diversity, 14: 729 [22 p.]

Recent observations suggest that climate change affects the growth conditions and range of tree species distribution in Europe. This may also have a major effect on communities of different organisms associated with these tree species. We aimed to determine whether Larix sp. could provide suitable habitats to insects and lichens associated with P. abies to conserve their biodiversity under climate change. The study sites were 10 Larix sp. and 10 P. abies forest stands in Lithuania. Both living … URL EndNote Read more...

Ndhlovu N.T., Solhaug K.A., Minibayeva F. & Beckett R.P. (2022): Melanisation in boreal lichens is accompanied by variable changes in non-photochemical quenching - Plants, 11(20): 2726 [13 p.]

Lichens often grow in microhabitats where they absorb more light than they can use for fixing carbon, and this excess energy can cause the formation of harmful reactive oxygen species (ROS). Lichen mycobionts can reduce ROS formation by synthesizing light-screening pigments such as melanins in the upper cortex, while the photobionts can dissipate excess energy radiationlessly using non-photochemical quenching (NPQ). An inherent problem with using fluorimetry techniques to compare NPQ in pale and … URL EndNote Read more...

Fernández-Prado N., Aragón G., Prieto M., Benítez Á. & Martínez I. (2022): Differences in epiphytic trunk communities in secondary forests and plantations of southern Ecuador - Forestry, 2022: cpac034 [17 p.]

Deforestation is the most important cause of biodiversity loss in tropical ecosystems. Epiphytic species, lichens and bryophytes, are very sensitive to environmental changes, including those produced by conversion of primary forests into secondary vegetation. However, little is known about the differences between different secondary forests and plantations regarding the epiphytic biota. We compared epiphytic communities among different secondary forests and non-native plantations in southern … URL EndNote Read more...

Garrido-Benavent I., Molins A. & Barreno E. (2022): Genetic variation in the symbiont partners in the endangered macrolichen Seirophora villosa (Teloschistaceae: Ascomycota) - Botanical Journal of the Linnean Society, 199(4): 816–829

The decline observed in many populations of highly sensitive lichens has led to the inclusion of some species on regional Red Lists, but this has seldom been accompanied by an examination of the genetic variation of the fungal and algal symbiotic partners. Here, the red-listed epiphytic lichen Seirophora villosa was surveyed in 14 Mediterranean coastal populations to examine the genetic diversity of both partners. The geographical distribution of four-locus haplotypes followed the same trend … URL EndNote Read more...
