Wieder R.K. (2022): Element stoichiometry and nutrient limitation in bog plant and lichen species - Biogeochemistry, 160: 355–379

Ombrotrophic bogs receive new inputs of elements solely through atmospheric deposition, except for N where inputs are predominantly through N2-fixation, at least in low N deposition environments. At various locations across the globe, including the Athabasca Oil Sands Region (AOSR) of northern Alberta, Canada, element atmospheric deposition has increased as a result of anthropogenic activities. Regional and/or global deposition gradients offer an opportunity to examine questions related to nutrient … Read more...

Isidorov V.A., Pirożnikow E., Spirina V.L., Vasyanin A.N., Kulakova S.A., Abdulmanova I.F. & Zaitsev A.A. (2022): Emission of volatile organic compounds by plants on the floor of boreal and mid‑latitude forests - Journal of Atmospheric Chemistry, 79: 153–166

The forests of the boreal and mid-latitude zones of the Northern Hemisphere are the largest source of reactive volatile organic compounds (VOCs), which have an important impact on the processes occurring in the atmospheric boundary layer. However, the composition of biogenic emissions from them remains incompletely characterized, as evidenced by the significant excess OH radical concentrations predicted by models in comparison with those observed under the forest canopy. The missing OH sink in the … Read more...

David M.L.R., Innasimuthu G.M., Rajaram S.K. & Nooruddin T. (2022): An endophytic Streptomyces sp. DARP-7 isolated from coastal lichen and enhancement of its antibacterial metabolite production using response surface methodology - South African Journal of Botany, 151: 636–648

Actinomycete DARP-7 was isolated from the coastal foliose lichen Dirinaria aegilita (Afzel.ex Ach.) B.J.Moore and identified as Streptomyces sp. using 16S rRNA sequencing. Among the eight culture media used for antimicrobial metabolite production, the peptone yeast extract iron medium (ISP-6) showed higher production with the maximum zone of inhibition (12 mm) against Staphylococcus aureus. Further, the ISP-6 medium components were optimized through the Plackett-Burman design (PBD) followed by Response … Read more...

Dhaouadi S., Khalloufi N., Ayati K., Ayeb N. & Béjaoui M. (2022): Use of lichen species for air pollution biomonitoring: Case of Dar-Chichou forest (Cap-Bon, North-East Tunisia) - Environmental and Sustainability Indicators, 16: 100211 [9 p.]

In the present work, we investigated the bio-uptake of 4 MTE (Ni, Cd, Pb, Zn) in the thalli of some species of lichens near a road crossing the Dar-Chichou forest (NE- Tunisia). In the absence of previous studies on the lichenic heritage of this forest, the objectives of this work are. first of all to identify for the first time the lichen species present in the forest, to determine the impact of this road pollution on certain physiological parameters of these pioneer species, such as the chlorophyll … Read more...

Cowden P., Hanner R., Collis B., Kuzmina M., Conway A., Ivanova N. & Stewart K. (2022): Early successional changes in biological soil crust community assembly and nutrient capture in mining impacted landscapes - Soil Biology and Biochemistry, 175: 108841 [13 p.]

Biological soil crusts (BSCs) are communities of bryophytes, lichens, bacteria, and fungi and are the primary colonizing communities in early successional landscapes. In early ecosystem development BSCs often improve the physical and chemical conditions while also promoting soil microbial communities. Although BSCs are considered ecosystem engineers in many early successional environments, the links between BSC functional processes and their developmental stage are unclear, especially in landscapes … Read more...

Rola K., Latkowska E., Ogar W. & Osyczka P. (2022): Towards understanding the effect of heavy metals on mycobiont physiological condition in a widespread metal-tolerant lichen Cladonia rei - Chemosphere, 308: 136365 [9 p.]

Heavy metals present in the environment can cause a variety of injury symptoms in various organisms including lichens. Most studies examined metal-induced stress under controlled laboratory conditions, and little is known about actual response of lichens in their natural habitat. This study aims to recognize the effect of heavy metal accumulation (total and intracellular) on lichen physiological and biochemical parameters specifically related to the functioning of fungal component. Cladonia rei was … Read more...

Kuzmina D., Lim A.G., Loiko S.V. & Pokrovsky O.S. (2022): Experimental assessment of tundra fire impact on element export and storage in permafrost peatlands - Science of The Total Environment, 853: 158701 [13 p.]

Extensive studies have been performed on wildfire impact on terrestrial and aquatic ecosystems in the taiga biome, however consequences of wildfires in the tundra biome remain poorly understood. In such a biome, permafrost peatlands occupy a sizable territory in the Northern Hemisphere and present an extensive and highly vulnerable storage of organic carbon. Here we used an experimental approach to model the impact of ash produced from burning of main tundra organic constituents (i.e., moss, lichen … Read more...

Ryde I., Davie-Martin C.L., Li T., Naursgaard M.P. & Rinnan R. (2022): Volatile organic compound emissions from subarctic mosses and lichens - Atmospheric Environment, 290: 119357 [12 p.]

Plant volatile organic compound (VOC) emissions can drive important climate feedbacks. Although mosses and lichens are important components of plant communities, their VOC emissions are poorly understood. It is crucial to obtain more knowledge on moss and lichen VOCs to improve ecosystem VOC emission models. This is especially relevant at high latitudes, where mosses and lichens are abundant and VOC emissions are expected to increase in response to climate change. In this study, we examined VOC emissions … Read more...

Adenubi O.T., Famuyide I.M., McGaw L.J. & Eloff J.N. (2022): Lichens: An update on their ethnopharmacological uses and potential as sources of drug leads - Journal of Ethnopharmacology, 298: 115657 [25 p.]

Ethnopharmacological relevance: Lichens, a unique symbiotic association between an alga/cyanobacterium and a fungus, produce secondary metabolites that are a promising source of novel drug leads. The beauty and importance of lichens have not been adequately explored despite their manifold biological activities such as anticancer, antimicrobial, antioxidant, anti-inflammatory, analgesic, antipyretic and antiparasitic. Aim of the study: The present review collates and discusses the available knowledge … Read more...

Wieder R.K., Scott K.D., Vile M.A. & Herron C. (2022): Are bog plant/lichen tissue concentrations of Ca, Mg, K, and P affected by fugitive dust released from oil sands development in the Fort McMurray region of Alberta? - Science of The Total Environment, 849: 157684 [12 p.]

Bogs are ombrotrophic, relying solely on atmospheric deposition for new inputs of elements. Increased element deposition through anthropogenic activities has the potential to alter nutrient availability, and hence ecosystem function, in bogs. Further, because of efficient element retention, bogs may function as effective monitors of element deposition. To assess the potential effects of particulate fugitive dust from oil sands development in Alberta, Canada, we quantified plant/lichen tissue Ca, … Read more...
