Meyer K. (2023): The Symbiosis of Lichenometry And Radiocarbon Dating: A Bayesian Chronology of Alpine hunting in Colorado’s Southern Rocky Mountains, USA, Radiocarbon, 65: 1-31

Archaeologists keep a limited arsenal of methods for dating stone features at alpine sites. Radiocarbon ( ¹⁴ C) dating is rarely possible, and it is common that dates do not accurately represent the activity of interest (stone feature construction). In this paper I review a legacy set of 89 ¹⁴ C dates for stone driveline sites built by hunter-gatherers in Colorado’s Southern Rocky Mountains. I amend the sample of dates using chronometric hygiene and focus on dates with direct association … Read more...

Kantvilas G. & Motiejūnaitė J. (2023): Two new lichenicolous species of Arthonia (Ascomycota: Arthoniomycetes) from Tasmania, Folia Cryptogamica Estonica, 60: 13-19

Eight lichenicolous species of Arthonia from Tasmania are treated. Two are described as new: A. aurantia Kantvilas & Motiej., which infects the thallus of a Leprocaulon-like lichen and is characterised by vivid orange, K+ magenta ascomata, 0.07−0.1(−0.15) mm wide, and 1-septate, macrocephalic ascospores, 10−12.5(−13.5) × 4−5.5 µm; and A. endocarpa Kantvilas & Motiej., which infects the apothecia of Amandinea neoconglomerata Elix, and has non-amyloid asci interspersed with those of the … Read more...

Roux, parasite on the thallus and apothecia of Lecania olivacella (note on the latter). Comparison of the new species with other known Zwackhiomyces.

Wirth V., Müller J., Pfiz M., Loris K. & Küppers M. (2010): Lichen distribution along an ocean-inland transect in the fog zone of the Central Namib, Biodiversity in Southern Africa, 2: 112–117

The lichen flora on gravel plains in the Namib-Desert fog zone north of Swakopmund in Namibia was investigated at 25 sites along a transect extending from the coast 40 km inland. In total, 42 lichen species were found, classified into four groups with different distribution patterns: (1) species present both inland and along the coast, (2) species restricted to the coast, (3) species common inland but absent from the coast, and (4) species occupying zones further inland. Both climatic and mechanical … Read more...

Nagar S., Pigott M., Kukula-Koch W. & Sheridan H. (2023): Unravelling Novel Phytochemicals and Anticholinesterase Activity in Irish Cladonia portentosa, Molecules, 28(10): 4145

Acetylcholinesterase inhibitors remain the mainstay of symptomatic treatment for Alzheimer's disease. The natural world is rich in acetylcholinesterase inhibitory molecules, and research efforts to identify novel leads is ongoing. Cladonia portentosa, commonly known as reindeer lichen, is an abundant lichen species found in Irish Boglands. The methanol extract of Irish C. portentosa was identified as an acetylcholinesterase inhibitory lead using qualitative TLC-bioautography in a screening program. … Read more...

Ramírez N., Sigurbjörnsdóttir M.A., Monteil C., Berge O., Heiðmarsson S., Jackson R.W., Morris C. & Vilhelmsson O. (2023): Pseudomonas syringae isolated in lichens for the first time: Unveiling Peltigera genus as the exclusive host, Environ Microbiol, 25(12): 3502-3511

Pseudomonas syringae is a bacterial complex that is widespread through a range of environments, typically associated with plants where it can be pathogenic, but also found in non-plant environments such as clouds, precipitation, and surface waters. Understanding its distribution within the environment, and the habitats it occupies, is important for examining its evolution and understanding behaviours. After a recent study found P. syringae living among a range of vascular plant species in Iceland, … Read more...

Pacle M., Apura J. & Paran R. (2022): Species Richness Of Macrolichens In Mt. Sapinit, Sitio Dagulos, La Roxas, Maramag, Bukidnon, International Journal of Applied Science and Research, 06: 167-179

The species richness of macrolichens in Mt. Sapinit, SitioDagulos, and MaramagBukidnon was investigated. The main objective of the study is to determine the species richness of macrolichens in the vicinity of Mt. Sapinit. Transect walk and quadrat sampling were carried out in the collection of macrolichens. The gathering and identification of specimens collected was based on standard taxonomical procedure. Results of the study revealed a total of 20 species classified into 7 genera and 13 families. … Read more...

Li X., Sun J., Zhang H., Tan H., Hui R., Qi J., Zhang P. & Ward N.D. (2023): Warming decreases desert ecosystem functioning by altering biocrusts in drylands, Journal of Applied Ecology, 60(12): 2676-2687

Abstract Warming and precipitation fluctuations are changing desert ecosystems in global drylands. However, the effects of climate change on keystone species such as cryptogamic biocrust in drylands remain relatively under-investigated, even though biocrusts play a vital role in desert ecosystems. We conducted a long-term experiment (14 years) to simulate the responses of two main types of biocrusts to warming coupled with reduction in precipitation that was achieved by open-top chambers (OTCs) … Read more...
