Haukenes V.L., Åsgård L., Asplund J., Nybakken L., Rolstad J., Storaunet K.O. & Ohlson M. (2022): Spatial variation of surface soil carbon in a boreal forest – the role of historical fires, contemporary vegetation, and hydro-topography - Scandinavian Journal of Forest Research, 37: 287–294

Knowledge about the spatial variation of boreal forest soil carbon (C) stocks is limited, but crucial for establishing management practices that prevent losses of soil C. Here, we quantified the surface soil C stocks across small spatial scales, and aim to contribute to an improved understanding of the drivers involved in boreal forest soil C accumulation. Our study is based on C analyses of 192 soil cores, positioned and recorded systematically within a forest area of 11 ha. The study area is … URL EndNote Read more...

Dufour B., Hébert F. & Boucher J.-F. (2024): Temporal changes in forest floor carbon stocks following scarification in boreal lichen woodlands - Scandinavian Journal of Forest Research, 39(2): 101–109

Uncertainties remain regarding the carbon (C) loss due to scarification in afforested lichen woodlands (LW), which originate from regeneration failures of closed-crown black spruce- feathermoss stands due to compounded disturbances. Therefore, the objective of this study was to characterize the C stock changes in the forest floor of scarified, unharvested LWs. Ten afforestation trials were established from 1999 to 2014 in LWs in the managed boreal forest of Québec. Ground surface layers were … URL EndNote Read more...

Vitória N.S., Silva M.S.R.C., Santos M.A.L., Cáceres M.E.S., Aptroot A. & Bezerra J.L. (2024): Ascomycota in the Shallow Ecoregion of Catarina, Caatinga, Brazil: Part 1 - Revista de Gestão Social e Ambiental, Miami, 18(7): e06047 [20 p.]

Objective: Inventories of fungi are essential, but they are rarely carried out, especially in areas of the Caatinga biome. It is therefore important to carry out surveys and mapping to make knowledge more accessible. In this context, the aim of this work was to organize and discuss the information and data related to the fungi of Raso da Catarina, cataloguing and presenting the first checklist of Ascomycota in an insufficiently researched locality, adding knowledge from scientific collections, … EndNote PDF Read more...

Miguel-Vázquez M.I., Simijaca D., Pérez-Pérez R.E. & Ocampo G. (2022): Lichenized fungi of the arid zones of central Mexico: new records for the country and the state of Aguascalientes - Sydowia, 74: 15–31

The lichen biota of several regions of Mexico is scarcely known, including the central part of the country, where the state of Aguascalientes is located. Before this study, lichen records of Aguascalientes were almost nonexistent. The aim of this work was to catalogue the lichen biota from arid environments of Aguascalientes, a widespread habitat in this part of Mexico. A total of 253 samples were collected and 20 families, 44 genera, and 56 lichen species were detected. The families with the … URL EndNote Read more...

Xue J., Cai Y. & Zhang L. (2024): The phylogeny and taxonomy of Cryptothecia (Arthoniaceae, Ascomycota) and Myriostigma (Arthoniaceae, Ascomycota), including three new species and two new records from China - Journal of Fungi, 10(4): 274 [15 p.]

Cryptothecia and Myriostigma are important elements of crustose lichen communities in tropical to subtropical forests, but little research has been done on these two genera in China. Morphological and molecular phylogenetic approaches to investigate species diversity of Cryptothecia and Myriostigma from Southern China were carried out in this study. We find five species of Cryptothecia and Myriostigma in our study, including three new species (M. flavescens, M. hainana and M. laxipunctata) and two … URL EndNote PDF Read more...

Fałowska P., Dziurowicz P., Waszkiewicz K., Wietrzyk-Pełka P. & Węgrzyn M.H. (2024): The impacts of sunlight on the lichen Scots pine forest community - Forests, 15(4): 675 [19 p.]

The habitat of the lichen Scots pine forest is currently one of the communities that requires attention and active protection due to its rapid disappearance. In our study, we identified factors that can be modified to preserve this habitat. The primary focus of our research was on the significance of tree height and sunlight in fostering the development of a lichen-rich layer within the lichen Scots pine forest. Additionally, we investigated the environmental factors influencing the presence of specific … URL EndNote PDF Read more...

Razzaq F., Usman M., Habib K. & Khalid A.N. (2023): Some Additions to the Lecanoraceae from Diamir Gilgit Baltistan, Pakistan - Biology Bulletin, 50(SUPPL 4): S617-S622

As part of comprehensive study of lichen diversity of northern areas of Pakistan using molecular and morphological approaches, we found three species of family lecanoraceae belonging to genus Omphalodina and Rhizoplaca. The analyses revealed one new record in the lichen biota of Pakistan namely Rhizoplaca parilis while the other two Omphalodina chrysoleuca and Rhizoplacamelanophthalma are reported for the first time on basis of ITS data, represent new records for Gilgit, Baltistan.

Gupta V., Gupta N., Nayaka S. & Lavania S. (2024): Delineating biomonitoring potential of two crustose lichens Bacidia convexula and B. submedialis through elemental accumulation and microstructural parameters - NUCLEUS-INDIA, 2024: 1-15

Lichens possess unique characteristics, relying on a protective cortex and a filtration mechanism for absorption in the absence of roots, enabling efficient mineral nutrition. However, this distinctive feature also renders them susceptible to accumulating airborne pollutants, particularly metal, beyond optimal levels. The current investigation focuses on elemental accumulation in two crustose lichen species, namely Bacidia convexula and B. submedialis, aiming to highlight their potential as biomonitoring … URL EndNote PDF Read more...

Chlorangium ahmadii sp. nov. and Circinaria darelensis sp. nov. are described as new species from Pakistan. A comparative morpho-anatomical, chemical study and ITS-based molecular analyses confrmed the positions of these species within the genera Chlorangium and Circinaria. Chlorangium ahmadii sp. nov. difers from its closely related species, C. alpicola in having light brown to whitish-brown thallus (vs. brownish-grey to greyish-green), fat to concave apothecial disc (vs. concave to convex … URL EndNote PDF Read more...

Fałtynowicz W., Czarnota P., Krzewicka B., Wilk K., Jabłońska A., Oset M., Ossowska E.A., Śliwa L. & Kukwa M. (2024): Lichens of Poland. A fifth annotated checklist - W. Szafer Institute of Botany, Polish Academy of Sciences, Kraków, 751 p

The current lichen checklist of Poland contains 1687 species and more than a dozen subspecies. At the same time, as a result of detailed analyses, as many as 130 species from the earlier lists of lichens of Poland (Fałtynowicz 2003, Fałtynowicz & Kossowska 2016) have been excluded; they were incorrectly reported from the country, or were found to have a negligible probability of occurrence, or the lack of herbarium specimens makes it impossible to verify the correctness of the designations. … EndNote Read more...
