Aamlid D., Vassilieva N., Aarrestad P.A., Gytarsky M. L., Lindmo S., Karaban R., Korotkov V., Rindal T., Kuzmicheva V. & Venn K. (2000): The ecological state of the ecosystems in the border areas between Norway and Russia - Boreal Env. Res., 5: 257–278

Six sites for forest ecosystem monitoring were established to perform a long-term study of effects of air pollution on pine forest ecosystems along a pollution gradient in the border areas between Norway and Russia. The main pollution source is a nickel smelter. Several methods and analyses were used to investigate different compartments of this northern boreal forest ecosystem. The differences in ecological condition and diversity observed among the research sites are probably due to the air pollution … EndNote Read more...

Aanderud Z.T., Bahr J., Robinson D.M., Belnap J., Campbell T.P., Gill R.A., McMillian B. & St. Clair S. (2019): The burning of biocrusts facilitates the emergence of a bare soil community of poorly-connected chemoheterotrophic Bacteria with depressed ecosystem services - Frontiers in Ecology and Evolution, 7: 467 [14 p.]

Wildfires destabilize biocrust, requiring decades for most biological constituents to regenerate, but bacteria may recover quickly and mitigate the detrimental consequences of burnt soils. To evaluate the short-term recovery of biocrust bacteria, we tracked shifts in bacterial community form and function in Cyanobacteria/lichen-dominated (shrub interspaces) and Cyanobacteria/moss-dominated (beneath Artemisia tridentata) biocrusts 1 week, 2 months, and 1 year following a large-scale burn manipulations … URL EndNote Read more...

Aartsma P., Asplund J., Odland A., Reinhardt S. & Renssen H. (2020): Surface albedo of alpine lichen heaths and shrub vegetation - Arctic, Antarctic, and Alpine Research, 52(1): 312–322

Lichen heaths are declining in abundance while shrubs are increasing their range in alpine and arctic areas due to climate change. This can have a large impact on the surface albedo of these areas. The aim of this article is to quantify the difference in albedo between lichen heaths and shrub-dominated vegetation and the variability within lichen heaths. Several environmental conditions that can influence the albedo measurements are considered. We measured the albedo of twenty lichen- and shrub-dominated … URL EndNote Read more...

Aartsma P., Odland A., Reinhardt S. & Renssen H. (2023): Drivers of soil temperature variation in alpine lichen heaths and shrub vegetation during the summer - Arctic, Antarctic, and Alpine Research, 55(1): 2209397 [13 p.]

Lichen heaths are decreasing in abundance in alpine and Arctic areas because of an increased competition with shrubs. This shift in vegetation might have important consequences for the soil temperature. The aim of this study is to find the drivers of the variation in soil temperature below lichen heaths and shrubs. Moreover, we want to gain more insight in the variability of the soil temperature below lichen heaths. We measured the soil temperature in thirty lichen plots and fifteen shrub plots … URL EndNote PDF Read more...

Ababaikeli G., Abbas A., Guo S.-Y., Tumier A. & Mamuti R. (2016): Diploschistes tianshanensis sp. nov., a corticolous species from Northwestern China - Mycotaxon, 131(3): 565–574

Diploschistes tianshanensis is described as a new species, found on rotten wood with mosses and other lichens (Cladonia sp.) in an arid region of Northwestern China. The new fungus, which is diagnosed by urceolate ascomata and large ascospores, resembles D. gypsaceus but is readily distinguished by its epruinose thallus surface. ITS rDNA sequence analyses support the taxon as a distinct species. The description of D. tianshanensis is accompanied by notes on its chemistry, distribution and ecology, … EndNote Read more...

Ababaikeli G., Abdulla A., Abbas A., Guo S.-Y. & Tumur A. (2018): Diploschistes wui sp. nov., an overlooked saxicolous lichen from Northwestern China - Mycotaxon, 133(1): 141–148

Diploschistes wui is described as a new species, based on three collections from Xinjiang in Northwestern China. It is characterized by a bluish gray and thin thallus, epruinose discs, small, 8-spored asci, and small ascospores. The new lichen resembles D. rampoddensis but is readily distinguished by the absence of surface crystals and pruinose discs. It grows on rocks at elevations above 1800 m. Our ITS rDNA sequence analyses support this species as independent. Key words—biodiversity, central … EndNote Read more...

Abakumov E., Lupachev A. & Andreev M. (2017): Trace element content in soils of the King George and Elephant islands, maritime Antarctica - Chemistry and Ecology, 33(9): 856–868

Trace element concentrations were studied in soils of the King George and Elephant islands in the maritime part of West Antarctica. The lowest concentrations of Cu, Pb, Cd, Zn, Ni and Mn were typical for the pristine soil of Elephant Island. The highest concentrations of these elements were found in the Fildes Peninsula and revealed the influence of human activities in the area of the Bellingshausen station and adjacent waste disposal sites. Ornithogenic soils of the Fildes Peninsula have shown low … EndNote Read more...

Abas A. (2021): A systematic review on biomonitoring using lichen as the biological indicator: A decade of practices, progress and challenges - Ecological Indicators, 121: 107197 [11 p.]

Various methods have been developed to monitor environmental quality, including biomonitoring using lichen. In this paper, a total of 143 previous studies from the last decade were analyzed to gain insight into current practices, progress, and challenges. Content analysis was employed to systematically characterize and classify the existing biomonitoring using lichen studies into several groups based on research area and scope. Various aspects of current biomonitoring applications using lichen … URL EndNote Read more...

Urban air pollution has been a major concern due to its impact on global public health. Various techniques for monitoring urban air quality have been developed. However, there is currently a dearth of research on how effective bioaccumulators such as lichen are at monitoring urban air pollution. As a result, the purpose of this research is to investigate the use of U. misaminensis as a biological indicator for biomonitoring urban air quality in Malaysia. Three months were spent exposing lichen samples … URL EndNote Read more...

Abas A., Asnawi N.H., Aiyub K., Awang A. & Abdullah S.R. (2022): Lichen Biodiversity Index (LBI) for the assessment of air quality in an industrial city in Pahang, Malaysia - Atmosphere, 13(11): 1905 [15 p.]

Lichen is a well-documented useful biological indicator for monitoring air pollution using various methods such as the biodiversity of lichens. However, the use of lichen biodiversity to estimate air pollution levels in industrial areas, particularly in Malaysia, is still weak, and the determinants of its diversity are unknown. As a result, the purpose of this research is to analyse air pollution in Malaysia’s industrial urban area using the lichen biodiversity index and its determining factor. … URL EndNote Read more...
