Tomović J., Kočović A., Anđić M., Bradić J., Zubić N., Jakovljević V., Sovrlić M., Vasiljević P. & Manojlović N. (2024): Bioactive components analysis and pharmacological properties of extracts and metabolites of lichen Umbilicaria crustulosa - Scientia Pharmaceutica, 92(2): 27 [16 p.]

Lichens, a diverse group of organisms, have a unique structure consisting of fungal filaments and photosynthetic partner cells. This research conducted a comprehensive chemical analysis and evaluation of the anti-inflammatory and antioxidant properties of methanolic and acetone extracts from Umbilicaria crustulosa lichen, along with its isolated metabolites. The process involved separating atranorin and chloratranorin fractions, physodic acid, and gyrophoric acid. Secondary metabolites were identified … URL EndNote PDF Read more...

Temu S.G., Tibell S., Tibuhwa D.D. & Tibell L. (2024): Coniocybe Ach. revisited - Journal of Fungi, 10(5): 363 [12 p.]

Calicioids form a research field that has encompassed ascomycetous fungi with stalked ascomata similar to those of the lichen genus Calicium. Early generic circumscriptions of calicioid lichens and fungi were mainly based on morphological and secondary chemistry information. After the introduction of molecular data, taxonomy in the group has been reconsidered. Here, based on a broad geographical sampling, Coniocybe Ach. was revised using molecular and morphological features. Three loci (ITS, … URL EndNote PDF Read more...

Taurozzi D., Gallitelli L., Cesarini G., Romano S., Orsini M. & Scalici M. (2024): Passive biomonitoring of airborne microplastics using lichens: A comparison between urban, natural and protected environments - Environment International, 187: 108707 [10 p.]

Currently, natural and urban ecosystems are affected by different types of atmospheric deposition, which can compromise the balance of the environment. Plastic pollution represents one of the major threats for biota, including lichens. Epiphytic lichens have value as bioindicators of environmental pollution, climate change, and anthropic impacts. In this study, we aim to investigate the lichen bioaccumulation of airborne microplastics along an anthropogenic pollution gradient. We sampled lichens … URL EndNote PDF Read more...

Bjerke J.W., Magnussen K., Bright R.M., Navrud S., Erlandsson R., Finne E.A. & Tømmervik H. (2024): Synergies and trade-offs between provisioning and climate-regulating ecosystem services in reindeer herding ecosystems - Science of the Total Environment, 927: 171914 [13 p.]

Reindeer (Rangifer tarandus) pastoralism utilizes vast boreo-arctic taiga and tundra as grazing land. Highly fluctuating population sizes pose major challenges to the economy and livelihood of indigenous herder communities. In this study we investigated the effect of population fluctuations on core provisioning and regulating ecosystem services in two Sámi reindeer herding districts with contrasting fluctuation trends. We compared 50-year long time series on herd size, meat production, forage productivity, … URL EndNote PDF Read more...

Conway S.N., McCune B. & Henkel T.W. (2024): Lichen diversity in serpentine habitats of the North Coast Range, California - Bryologist, 172(2): 220–232

Macrolichen diversity and community composition were determined for an area of high botanical interest in the Coast Ranges of Northern California – the Horse Mountain Botanical Area (HMBA) in Six Rivers National Forest. The Coast Ranges have been suggested to have high lichen diversity, yet detailed site-specific macrolichen surveys are lacking for the area. The HMBA is characterized by the presence of ultramafic (serpentine) soils, contributing to its diverse assemblage of conifers. Here we present … URL EndNote Read more...

Nature-based solutions (NBSs) are becoming more and more recognized as useful instruments to address the challenges that urban areas are currently facing, i.e., climate change adaptation, flood mitigation, etc. In the present study, we aimed to: (1) compare the efficiency of mosses, lichens, herbs and trees in removing pollutants from the urban air using their biomonitoring potential; (2) assess their efficiency as nature-based solutions to mitigate urban air pollution; and (3) propose a framework … URL EndNote PDF Read more...

Meng X., Zhang X., Li Y., Jiao Y., Fan L., Jiang Y., Qu C., Filimonenko E., Jiang Y., Tian X., Shi J. & Kuzyakov Y. (2024): Nitrogen fertilizer builds soil organic carbon under straw return mainly via microbial necromass formation - Soil Biology and Biochemistry, 188: 109223

Carbon (C) and nitrogen (N) inputs strongly influence the formation, turnover and sequestration of soil organic carbon (SOC) in agricultural ecosystems. It is not clear, however, how N input regulates the contribution of plant- and microbial-derived C to SOC sequestration under straw return. To fill this gap, plant and microbial biomarkers, as well as enzyme activities were determined in a long-term (18 years) field experiment. Straw return and N fertilization increased SOC content by 20% and 10%, … URL EndNote PDF Read more...

Xu L., Li C.A., Xiong W.J., Kou Y.P., Zou P., Jiao B.J., Yao M.J., Wang J.M., Zhang B.C. & Li X.Z. (2024): The composition of soil fungal communities is more dependent on biocrust type than on shrub cover in the Mu Us Desert - Fungal Ecology, 2024: 70

Desertification-control policies have been applied in the Mu Us Desert since the 1950s. The landscape there is characterized by patches of shrub plants and well-developed lichen and moss crusts, some covered by shrub canopies and some in interspace soils. Little is known about how shrub cover and biocrusts shape soil fungal community structure in this ecosystem. Using high-throughput amplicon sequencing, the effects of biocrust types and shrub cover on soil fungal communities were analyzed. The results … URL EndNote PDF Read more...

Sun J., Yu K., Chen N., Munson S.M., Li X. & Jia R. (2024): Biocrusts modulate carbon losses under warming across global drylands: A bayesian meta-analysis - Soil Biology and Biochemistry, 188: 109214

Biocrusts are critical biological components of drylands and play an important role in soil carbon (C) cycling. However, the effect of biocrusts on soil CO2 exchange across global gradients of temperature and moisture is poorly understood. Moreover, their response to climate change remains highly uncertain. Bayesian hierarchical meta-analyses were performed on 47 published studies to quantify the impact of biocrusts on net soil exchange (NSE) of carbon- the difference between respiration and photosynthesis. … URL EndNote PDF Read more...
