Bacciu N.G. & McGill J. (2023): Gathering twig lichen data for Powys SSSIs to investigate ammonia levels: Second phase - Natural Resources Wales Evidence Report, 676: 1-90

Nine SSSI in Powys were surveyed for twig lichens in January 2023, following a modified version of the Air Pollution Information System protocol (Wolseley et al., 2017, Bosanquet, 2018). Five trees at each SSSI were sampled, comprising a total of 37 oaks, 2 birches, and 6 hawthorns. Based on these data, the ammonia pollution levels at locations surveyed within the SSSIs were assessed as follows: • Clean – Berwyn, and Coed yr Allt Goch. • At risk – Cwmsaise, and Greygnog. • N polluted – … URL EndNote PDF Read more...

Bosanquet S.D.S. (2018): Lichen surveys to investigate ammonia impacts - Natural Resources Wales Evidence Report, 298: 1-126

This Evidence Report brings together six internal reports prepared by Sam Bosanquet, NRW Non-vascular Plant Ecologist, following fieldwork in 2017, and one report commissioned from an external lichen expert. Each of these reports provided stand-alone evidence of the negative impacts of ammonia on lichens on Sites of Special Scientific Interest (SSSIs) in Wales. The results of each survey helped to inform the others, so there is repetition in the aims, methods and discussion, but each has already … URL EndNote Read more...

Li L., Zhang Y., Printzen C., Wang L. & Wang X. (2023): The phylogeny and taxonomy of Upretia (Caloplacoideae, Teloschistaceae), reveal three new species from Southwestern China - MycoKeys, 100: 233–243

Several specimens of Upretia from Southwest China are morphologically and phylogenetically distinct from currently recognized species in the genus. These specimens are here accommodated within a new species, Upretia zeorina Li J. Li & Printzen. It is characterized by an areolate to squamulose thallus with brown to blackish brown upper surface, pruinose, zeorine type apothecia, black discs, narrowly bacilliform conidia, and the production of gyrophoric acid. Two other specimens of Upretia from China … URL EndNote Read more...

Cannone N., Guglielmin M. & Ponti S. (2023): Suitability and limitations of ground-based imagery and thermography for long-term monitoring of vegetation changes in Victoria Land (continental Antarctica) - Ecological Indicators, 156: 111080

Antarctic vegetation has been recognized to be a valuable bio-indicator to track climatic and environmental changes through an accurate long-term monitoring. The extremely harsh climatic conditions of Antarctica, its limited logistical accessibility and remoteness encourage the substitution or integration of field surveys with remote sensing monitoring. Here we assess the applicability and limitations of ground-based remote sensing (visible imagery and thermography) for accurate long-term monitoring … URL EndNote PDF Read more...

Cerrejón C., Valeria O. & Fenton N.J. (2023): Estimating lichen α- and β-diversity using satellite data at different spatial resolutions - Ecological Indicators, 149: 110173 [9 p.]

Understanding biodiversity patterns and its environmental drivers is crucial to meet conservation targets and develop effective monitoring tools. Inconspicuous species such as lichens require special attention since they are ecologically important but sensitive species that are often overlooked in conservation planning. Remote sensing (RS) can be particularly beneficial for these species as in combination with modelling techniques it allows planners to assess and better understand biodiversity patterns. … URL EndNote PDF Read more...

Conti M.E., Rapa M., Pla R., Jasan R., Tudino M.B., Canepari S., Massimi L. & Astolfi M.L. (2023): Elemental and chemometric analysis of baseline gradient contamination in Usnea barbata lichens from Tierra del Fuego (South Patagonia) - Microchemical Journal, 185: 108283

In order to provide an updated baseline assessment of elemental concentrations in native lichens samples collected at eight selected sampling sites from Tierra del Fuego (South Patagonia), we have determined the concentration of more than forty elements in Usnea barbata by means of different analytical techniques (INAA, ICP-MS, ICP-OES, AMA and CV-AFS), and compared the results in order to ensure reliable data at the moment to perform a comprehensive management of pristine environments. New chemometrics … URL EndNote PDF Read more...

de Alcantara Viana J.V., Campos Duarte R., Vieira C., Augusto Poleto Antiqueira P., Bach A., de Mello G., Silva L., Rabelo Oliveira Leal C. & Quevedo Romero G. (2023): Crypsis by background matching and disruptive coloration as drivers of substrate occupation in sympatric Amazonian bark praying mantises - Scientific Reports, 13(1): 19985

Background matching and disruptive coloration are common camouflage strategies in nature, but few studies have accurately measured their protective value in living organisms. Amazon's Bark praying mantises exhibit colour patterns matching whitish and greenish-brown tree trunks. We tested the functional significance of background matching and disruptive coloration of different praying mantis morphospecies (white, grey and green) detected by DNA barcoding. Through image analysis, avian visual models … URL EndNote PDF Read more...

Diekmann M., Heinken T., Becker T., Doerfler I., Heinrichs S., Leuschner C., Peppler-Lisbach C., Osthaus M., Schmidt W., Strubelt I. & Wagner E. (2023): Resurvey studies of terricolous bryophytes and lichens indicate a widespread nutrient enrichment in German forests - Journal of Vegetation Science, 2023: 34

Questions Vegetation resurveys, both single studies and meta‐analyses, have predominantly been based on vascular plant data while bryophytes and lichens have largely been neglected. Our study aims to fill this gap and addresses the following research questions: has the overall species richness of terricolous bryophytes and lichens in forests changed over time? Which are the winners and losers among single species and ecological species groups? Do the results give a signal of the impact of nutrient … URL EndNote PDF Read more...

Dimitrijević I., Mitić V., Jovanović V., Stanković M., Zlatanovic I. & Stojanović G. (2023): Cladonia rangiformis Acetone Extract— New Insight into the Chemical Composition and Biological Activity - NATURAL PRODUCT COMMUNICATIONS, 2023: 18

Introduction Cladonia rangiformis, also known as reindeer lichen, has been used for various remedies in folk medicine. The rich nutritional value of this lichen is reflected in the fact that it contains atranorin, which has been proven to have numerous biological activities. Objective The chemical composition, antioxidant, anticholinesterase, and antigenotoxic activities of the C. rangiformis acetone extract were investigated. The novelty of this work is that anticholinesterase activity, protective … URL EndNote PDF Read more...

González Argüello G., Filippini E. & Machado A. (2022): Morpho-anatomical variations of Parmotrema pilosum (Parmeliaceae, Ascomycota) in fragmented forests of central Argentina: relationship between forest cover and distance to crops - Environmental Science and Pollution Research, 30

Forest vegetation is key for buffering microclimatic factors and regulating atmospheric deposition. Epiphytic lichens are sensitive to these factors and can indicate the overall health status of the ecosystem. Specifically, the analysis of morpho-anatomical variations allows us to understand the degree of tolerance or sensitivity of these organisms exposed to agricultural crops and how vegetation might buffer this response. We analyzed variations in vegetative and reproductive characters and injuries … URL EndNote PDF Read more...
