Andersen R., Fernandez-Garcia P., Martin-Walker A., Klein D., Marshall C., Large D.J., Hughes R. & Hancock M.H. (2024): Blanket bog vegetation response to wildfire and drainage suggests resilience to low severity, infrequent burning - Fire Ecology, 20: 26 [16 p.]

Background: In 2019, a wildfire impacted an area of blanket bog and wet heath > 60 km2 in the Flow Country peatlands of northern Scotland, a site of global significance. Unusually the footprint of the wildfire included discrete areas of degraded, restored, and near-natural blanket bogs. Following the wildfire, we surveyed vegetation in 387 quadrats in burnt and unburnt areas. The study aimed to determine whether and how proximity to human-made drains and microtopography affected fire-vegetation … Read more...

Best I.N., Brown L., Elkin C., Finnegan L., McClelland C.J.R. & Johnson C.J. (2024): Cut vs. fire: a comparative study of the temporal effects of timber harvest and wildfire on ecological indicators of the boreal forest - Landscape Ecology, 39: 81 [22 p.]

Context: Large-scale natural disturbances are crucial drivers of ecosystem function and composition for many forested ecosystems. In the last century, the prevalence of anthropogenic disturbances has increased across Canada’s boreal forest. Habitat disturbance from timber harvest and wildfire is linked to declines of boreal species, including woodland caribou (Rangifer tarandus caribou). Objectives: We tested how disturbances influenced the recovery trajectory of ecological indicators of timber, … Read more...

Beck K., Glew K., Hardman A., Lavdovsky N., McCune B., Nelson N., Ponzetti J., Rhoades F., Rosentreter R., Stone D., Theden T., Tønsberg T. & Villella J. (2024): Lichens of Cypress Island, Washington – the seen and the unseen - Evansia, 40(4): 136–155

A group of Northwest Lichenologists explored the lichen biodiversity on Cypress Island in the San Juan Islands on the Pacific coast north of Seattle, hosted by the Washington Department of Natural Resources. We compiled our observations separately by habitat: (1) uplands with serpentine bedrock, (2) uplands with basalt bedrock, and (3) rocky saltwater shorelines. Combining our results with previous efforts, we report 243 lichen species from Cypress Island. Despite the respectable species list, we … Read more...

Cui C., Li Y., Xu J., Zhao X. & Jia Z. (2024): Diorygma tiantaiense sp. nov. and a checklist and key to Diorygma species from China - Diversity, 16(4): 213 [12 p.]

A new species Diorygma tiantaiense Z.F. Jia, sp. nov. was found, which is characterized by a corticolous thallus with norstictic acid, oval or oblong apothecia, immersed to ± raised discs with white pruina, and large muriform ascospores (120–210 × 35–60 µm). Detailed morphological descriptions, photographs, and a comparison and discussion of similar species are provided. A checklist and key to the species of Diorygma known from China is presented. Keywords: lichenized fungi; lecanoromycetes; … Read more...

Paquette H.A., McMullin R.T. & Wiersma Y.F. (2024): The importance of taxonomy for determining species distribution: a case study using the disjunct lichen Brodoa oroarctica - Botany, 102(1): 10-18

Species-focused conservation requires a thorough understanding of species’ distributions. Delineating a species’ distribution requires taxonomic knowledge and adequate occurrence data. For plants and fungi, herbaria represent a valuable source of large-scale occurrence data. Advances in digital technology mean that data from many herbarium collections worldwide are now easily accessible. However, species concepts can change over time requiring herbarium records to be re-examined and databases … Read more...

Zueva A.S., Chesnokov S.V. & Konoreva L.A. (2024): Addition to the lichen biota of Paramushir Island (Northern Kuril Islands, Russian Far East) - Новости систематики низших растений [Novosti sistematiki nizshikh rastenii] / Novitates systematicae plantarum non vascularium, 58(1): L35–L53

The paper provides data on 143 species, one subspecies, and one variety of lichens, 13 species of lichenicolous fungi and one species of non-lichenized saprobic fungus from Paramushir Island. One hundred thirty-eight taxa are reported for this territory for the first time. Of them, Lecanora confusa is reported for the first time for Russia, eight species are new to the Russian Far East, 36 species and one variety are new to the Sakhalin Region, 20 species are listed for the first time for the Kuril … Read more...

Rodionova A.A., Timofeeva E.A., Himelbrant D.E., Stepanchikova I.S., Zueva A.S., Tsurykau A.G., Frolov I.V. & Chesnokov S.V. (2024): The first survey of the lichen diversity of Seskar Island (Gulf of Finland, Leningrad Region) - Новости систематики низших растений [Novosti sistematiki nizshikh rastenii] / Novitates systematicae plantarum non vascularium, 58(1): L1–L25

The revealed lichen diversity of Seskar Island has a total of 292 species, including 263 lichenized, 20 lichenicolous, and nine non-lichenized saprobic fungi. Stigmidium microcarpum is new to European Russia, Caloplaca alcarum, Cryptodiscus muriformis, C. pini, and C. tabularum are new to North-Western European Russia; Lecidella subviridis and Pyrenidium actinellum are new to the Leningrad Region. The most interesting result of the investigation is the discovery of the single modern population … Read more...

Yakovchenko L.S. & Davydov E.A. (2024): Arthonia phaeobaea (Arthoniaceae, Ascomycota) new to Asia and Russia from the Sakhalin Region - Новости систематики низших растений [Novosti sistematiki nizshikh rastenii] / Novitates systematicae plantarum non vascularium, 58(1): L55–L60

During the study of the lichen biota of Sakhalin Island, Arthonia phaeobaea was identified basing of morphological and anatomical data. This is the first record of this rare saxicolous coastal lichen in Asia and Russia; the species was previously recorded only in Central and Northern Europe (including Arctic) and North America. The species is characterized by its thin, smooth, brown-gray continuous thallus without lichen compounds, usually with numerous black pycnidia and small, black, rounded to … 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...

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...
