Gillespie L.J., Sokoloff P.C., Levin G.A., Doubt J. & McMullin R.T. (2024): Vascular plant, bryophyte, and lichen biodiversity of Agguttinni Territorial Park, Baffin Island, Nunavut, Canada: an annotated species checklist of a new Arctic protected area - Check List, 20(2): 279-443

Agguttinni Territorial Park is a large, newly established park on the east-central coast of Baffin Island in Nunavut, Canada. Previous knowledge of the plant and lichen biodiversity was limited and based mostly on collections made during the 1950 Baffin Island Expedition. We conducted a ﬂoristic inventory of the park in 2021 and re-examined previous collections. We recorded 141 species of vascular plants belonging to 25 families, 69 species of bryophytes in 27 families, and 93 species of lichens … Read more...

Vagle G.L., Lendemer J.C., Manzitto-Tripp E.A. & McCain C.M. (2024): Patterns and predictors of lichen rarity in a biodiversity hotspot - Biodiversity and Conservation, (2024): 1-22

Understanding the spatial distributions of rarity and diversity is crucial for both targeted conservation efforts and elucidating the mechanisms that underpin species richness patterns. Existing studies suggest local communities with greater species richness also hold higher numbers of low abundance species. Rarity hotspots at the global scale tend to be spatially divergent from species richness hotspots and differ among many taxonomic groups, but much less work has been done to understand rarity … Read more...

Westberg M., Wedin M. & Svensson M. (2024): Myriospora molybdina comb. nov. and the identity of Acarospora hysgina - Nordic Journal of Botany, 2024: e04269

The nomenclature and taxonomy of Acarospora molybdina is revised using morphological and molecular data. The new combination Myriospora molybdina is proposed and Acarospora hysgina is recognized as a distinct species while A. brunneola is reduced to synonymy with A. hysgina. In its new circumscription M. molybdina is an arctic species, in Scandinavia only occurring in northernmost Norway. Further localities are reported from Greenland, Russia, Svalbard and the USA (Alaska). Acarospora hysgina is … Read more...

Jung P., Baumann K., Emrich D., Schermer M., Eckhardt K.-U., Jandl G., Leinweber P., Harion F., Wruck A., Grube M., Büdel B. & Lakatos M. (2024): The dark side of orange: Multiorganismic continuum dynamics within a lichen of the Atacama Desert - Mycologia, 116(1): 44–58

Over the decades our understanding of lichens has shifted to the fact that they are multiorganismic, symbiotic microecosystems, with their complex interactions coming to the fore due to recent advances in microbiomics. Here, we present a mutualistic-parasitic continuum dynamics scenario between an orange lichen and a lichenicolous fungus from the Atacama Desert leading to the decay of the lichen’s photobiont and leaving behind a black lichen thallus. Based on isolation, sequencing, and ecophysiological … Read more...

Pląskowska E., Patejuk K., Lorenc M.W. & Grzeszczuk J. (2024): Lichens and Fungi on Sandstone Tombs at the Historical Jewish Cemetery in Wrocław (Poland) - Studies in Conservation, 69(1): 58–66

Microflora inhabiting rock surfaces, including bacteria, fungi, algae, and lichens, form a specific kind of an ecosystem. Unique and not well known forms of this environment are old cemetery tombs. To better understand such environments, lichenological and mycological studies were conducted in the old Jewish cemetery in Wrocław, Poland. The research covered 13 tombstones made of several varieties of sandstone. This research shows that some gravestones made of sandstone from Wartowice were strongly … Read more...

Moya P., Chiva S., Pazos T., Barreno E., Carrasco P., Muggia L. & Garrido-Benavent I. (2024): Myco–phycobiont interactions within the “Ramalina farinacea group”: A geographical survey over Europe and Macaronesia - Journal of Fungi, 10(3): 206 [17 p.]

Ramalina farinacea is a widely distributed epiphytic lichen from the Macaronesian archipelagos to Mediterranean and Boreal Europe. Previous studies have indicated a specific association between R. farinacea and Trebouxia microalgae species. Here, we examined the symbiotic interactions in this lichen and its closest allies (the so-called “R. farinacea group”) across ten biogeographic subregions, spanning diverse macroclimates, analyzing the climatic niche of the primary phycobionts, and discussing … Read more...

Liang X., Chen W., Jiang B. & Xiao C.-J. (2024): Dibenzofurans from nature: Biosynthesis, structural diversity, sources, and bioactivities - Bioorganic Chemistry, 144: 107107 [17 p.]

Dibenzofurans are a small class of natural products with versatile biological activities that used to be thought to come mainly from lichens and ascomycetes. In fact, they are also distributed widely in higher plants, especially in the families Rosaceae and Myrtaceae. Dibenzofurans and derivatives from lichens and ascomycetes have been well reviewed, but dibenzofurans from all biological sources in nature have not been reviewed. In this review, dibenzofurans from all natural sources have been comprehensively … Read more...

Wilk K. & Lücking R. (2024): Quantitative integrative taxonomy informs species delimitation in Teloschistaceae (lichenized Ascomycota): the genus Wetmoreana as a case study - IMA Fungus, 15: 9 [42 p.]

The genus Wetmoreana was studied using quantitative integrative taxonomy methods to resolve the genus delimitation and explore its taxonomy diversity at the species level. As a result, the genus Fulgogasparrea is synonymized with Wetmoreana, and the latter includes 15 formally described species, one subspecies, and three further, thus far undescribed species: W. appressa, W. awasthii comb. nov., W. bahiensis sp. nov., W. brachyloba comb. nov., W. brouardii, W. chapadensis comb. nov., W. circumlobata … Read more...

Kidron G.J., Starinsky A. & Xiao B. (2024): The enigmatic enrichment of potassium and magnesium in runoff and floodwater in the Negev: Do biocrusts hold the key? - Science of The Total Environment, 911: 168753 [12 p.]

Hypothesizing that rock-dwelling (lithobionts) or soil (loess)-dwelling biocrusts may shed light on the phenomena, we conducted sprinkling experiments in the Negev Highlands. Sprinkling was conducted on 4 types of lithobionts: cyanobacteria which inhabit the south-facing bedrock (ENC), epilithic lichens, inhabiting the inclined (EPIi) and the flat (EPIf) north-facing bedrocks, and endolithic lichens (ENL) inhabiting south-facing boulders. Additional sprinkling took place on two types of soil biocrusts, … Read more...

Brenning M., Longstaffe F.J. & Fraser D. (2024): Variation in stable carbon (δ13C) and nitrogen (δ15N) isotope compositions along antlers of Qamanirjuaq caribou (Rangifer tarandus groenlandicus) - Ecology and Evolution, 14: e11006 [18 p.]

Annual antler growth begins in the spring and is completed by late summer for male caribou (Rangifer tarandus groenlandicus) from the Qamanirjuaq herd (Nunavut, Canada), aligned with both the spring migration and a seasonal dietary shift. Antlers may provide a non-lethal means of studying short- and long-term changes in caribou ecology through incorporated isotopes of carbon (δ13C) and nitrogen (δ15N). We sampled the antlers of 12 male caribou from the Qamanirjuaq herd culled in September 1967. … Read more...
