Paulsen J., Allen J.L., Morris N., Dorey J., Walke J.B. & Alter S.E. (2024): Geography, climate, and habitat shape the microbiome of the endangered Rock Gnome Lichen (Cetradonia linearis) - Diversity, 16(3): 178 [17 p.]

Bacterial symbionts are essential components of healthy biological systems. They are increasingly recognized as important factors in the study and management of threatened species and ecosystems. Despite management shifts at the ecosystem level, microbial communities are often neglected in discussions of holobiont conservation in favor of the primary members of a symbiosis. In this study, we addressed the bacterial community knowledge gap for one of two federally endangered lichen species in the … Read more...

Barbosa B.M.C., Santos L.A., Oliveira Junior I., Oliveira Lima D., Aptroot A. & Cáceres M.E.S. (2024): New records of Polymeridium (Müll.Arg.) R.C.Harris from Brazil with description of a new species from the Caatinga, and a checklist of the Brazilian species - Cryptogamie, Mycologie, 45(4): 39–46

A new species is described, Polymeridium stromatocorticatum B.Barbosa, Aptroot, L.A.Santos & M.Cáceres, sp. nov. found in the Caatinga Biome, collected at Raso da Catarina Ecological Station (Bahia, Brazil). The new species is characterized by the combination of a corticated thallus and aggregated ascomata, while the ascospores exhibit the typical characteristics of a Polymeridium (Müll.Arg.) R.C.Harris. The genus has its greatest absolute world diversity in this region of NE Brazil, especially … Read more...

Arcadia L., Ahti T., Benesperi R., de Paz G.A., Divakar P.K. & Hawksworth D. (2024): (3013) Proposal to conserve the name Lichen pullus Schreb. (Parmelia pulla, Xanthoparmelia pulla) against L. pullus Neck. (Parmeliaceae, lichenized Ascomycota) with a conserved type - Taxon, 2004: 1-2

The well-established name Xanthoparmelia pulla (Schreb.) O. Blanco & al. (or sometimes Neofuscelia pulla (Schreb.) Essl.) has been used to refer to a common, brown, foliose saxicolous lichen. The basionym had, however, long been considered to be Parmelia pulla Ach. (Syn. Meth. Lich.: 206. 1814), and so the type had been assumed to be an Acharian collection. A specimen of Parmelia pulla in H-ACH 1420D (= H9502152) conforming to current usage was therefore designated as lectotype by Esslinger & Ahti … Read more...

Motiejūnaitė J. (2024): Lithuanian lichens and lichenicolous fungi in the herbaria of the University of Tartu (Estonia) and the University of Latvia - Botanica, 30(1): 23–30

Herbarium collections are particularly significant in countries where systematic studies of specific taxonomic groups have not been carried out, such as in the case of lichens in Lithuania. Collections prior to the 1990s are scarce, so all historical material is of great value. This paper presents the results of a study of lichen collections in the herbaria of the University of Tartu (TU) and the University of Latvia (RIG). A total of 425 herbarium envelopes (84 RIG and 341 TU) were examined. A total … Read more...

He Z., Naganuma T., Nakai R., Uetake J. & Hahn M.W. (2024): Microbiomic analysis of bacteria associated with rock tripe lichens from alpine areas in eastern Alps and equatorial Africa - Current Microbiology, 81: 115 [17 p.]

The diversity of bacteria associated with alpine lichens was profiled. Lichen samples belonging to the Umbilicariaceae family, commonly known as rock tripe lichens, were gathered from two distinct alpine fellfelds: one situated on Mt. Brennkogel located in the Eastern European Alps (Austria), and the other on Mt. Stanley located in the Rwenzori mountains of equatorial Africa (Uganda). The primary aim of this research was to undertake a comparative investigation into the bacterial compositions, and … Read more...

Meysurova A.F., Notov A.A., Pungin A.V. & Skrypnik L.N. (2024): Application of optical spectroscopy for the analysis of physiological characteristics and elemental composition of lichens of the genus Hypogymnia with different degrees of anthropotolerance - Journal of Applied Spectroscopy, 91(1): 64–75

[Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 91, No. 1, pp. 74–86] The main physiological and biochemical characteristics and elemental composition of three lichen species of the genus Hypogymnia (Nyl.) Nyl. in one habitat were studied using spectroscopic methods. The model species were placed in the following order of decreasing degree of anthropotolerance: H. physodes (L.) Nyl. → H. tubulosa (Schaer.) Hav. → H. vittata (Ach.) Parrique. The contents of chlorophylls a and b, phenolic … Read more...

Rautiainen M., Kuusinen N. & Majasalmi T. (2024): Remote sensing and spectroscopy of lichens - Ecology and Evolution, 14: e11110 [16 p.]

Lichens are combinations of two symbiotic organisms, a green alga or cyanobacterium and a fungus. They grow in nearly all terrestrial ecosystems and survive in habitats, which are very dry or cold, or too poor in nutrients to maintain vegetation growth. Because lichens grow on visible surfaces and exhibit spectral properties, which are clearly different from, for example, vegetation, it is possible to distinguish them in remote sensing data. In this first systematic review article on remote sensing … Read more...

Fetzer J., Moiseev P., Frossard E., Kaiser K., Mayer M., Gavazov K. & Hagedorn F. (2024): Plant–soil interactions alter nitrogen and phosphorus dynamics in an advancing subarctic treeline - Global Change Biology, 30: e17200 [18 p.]

Treelines advance due to climate warming. The impacts of this vegetation shift on plant–soil nutrient cycling are still uncertain, yet highly relevant as nutrient availability stimulates tree growth. Here, we investigated nitrogen (N) and phosphorus (P) in plant and soil pools along two tundra–forest transects on Kola Peninsula, Russia, with a documented elevation shift of birch-dominated treeline by 70 m during the last 50 years. Results show that although total N and P stocks in the soil–plant … Read more...

Nikolić N., Zotz G. & Bader M.Y. (2024): Modelling the carbon balance in bryophytes and lichens: Presentation of PoiCarb 1.0, a new model for explaining distribution patterns and predicting climate‐change effects - American Journal of Botany, 111: e16266 [21 p.]

Premise: Bryophytes and lichens have important functional roles in many ecosystems. Insight into their CO2‐exchange responses to climatic conditions is essential for understanding current and predicting future productivity and biomass patterns, but responses are hard to quantify at time scales beyond instantaneous measurements. We present PoiCarb 1.0, a model to study how CO2‐exchange rates of these poikilohydric organisms change through time as a function of weather conditions. Methods: … Read more...

Berlinches de Gea A., Verdú M., Villar-dePablo M. & Pérez-Ortega S. (2024): The combined effects of habitat fragmentation and life history traits on specialisation in lichen symbioses - Journal of Ecology, 112: 200–216

Interactions between organisms are determined by life-history traits. Ecological strategies regarding species specialisation range from generalist to highly specialised relationships. Although it is expected that habitat fragmentation's effect on species abundance and survival depends on their degree of specialisation and life-history traits, few studies have delved into the interplay between interaction specialisation, life-history traits and habitat fragmentation.Here, we investigate the combined … Read more...
