Pradhan S., Dash S., Sahoo B., Parida S. & Rath B. (2024): Screening and characterization of bioactive compounds from two epiphytic microlichen and evaluation of their in vitro antioxidant activity - Future Journal of Pharmaceutical Sciences, 10: 10 [19 p.]

Background: Lichens in symbiosis produce a wide range of primary and secondary fne compounds in extreme environmental conditions that have a broad range of biological properties as well as antioxidant potential and can be used in future pharmaceuticals as a natural source of antioxidant molecules. Results: The two microlichen species collected are identifed based on morphological and molecular techniques; further studies are carried out by analyzing phytochemicals (FTIR, GC MS), and antioxidant … Read more...

Hirschheydt G. von, Kéry M., Ekman S., Stofer S., Dietrich M., Keller C. & Scheidegger C. (2024): Occupancy model reveals limited detectability of lichens in a standardised large-scale monitoring - Journal of Vegetation Science, 35: e13255 [11 p.]

Question: What are the extent and the possible causes of imperfect detection in lichens? Because lichens are sessile and lack seasonality, they should be easier to survey than animals that can move or plants and fungi with seasonal morphology, and one could therefore expect relatively high detection probabilities. Location: 826 standardised sampling plots across Switzerland. Methods: Using repeated detection/non-detection data from a national lichen survey conducted by professional lichenologists, … Read more...

Marshall A.J., Aptroot A., Vlůanchon D.J., James C.J. & de Lange P.J. (2024): New Zealand Lithothelium (Pyrenulaceae) — description of a new species Lithothelium kiritea sp. nov., with notes on L. australe - Український ботанічний журнал [Ukrainian Botanical Journal], 81(2): 145–154

Lithothelium kiritea A.J. Marshall, Aptroot, de Lange & Blanchon sp. nov. (Pyrenulaceae) is described from Aotearoa / New Zealand. The new species has a mainly coastal and mostly westerly distribution in Aotearoa / New Zealand and is thus far known only from the bark of living Cordyline australis (Asparagaceae). The new species is separated from Lithothelium australe (treated here as endemic to the Chatham Islands), by its corticolous, rather than saxicolous habit, white to pale buff (when … Read more...

Svanberg I. & Ståhlberg S. (2024): Peasant food provision strategies and scientific proposals for famine foods in eighteenth-century Sweden - Gastronomy, 2(1): 18–37

The peasant diet during the Little Ice Age in Sweden was mainly grain-based (bread, gruel, and porridge), and the country was heavily dependent on grain imports to meet the population’s needs for food. During the eighteenth century in particular, when famines were frequent following failed harvests, Swedish peasants utilized a range of locally available resources to survive. Bark bread made of cambium (phloem) from Pinus sylvestris was, for example, commonly used as famine food. Scientists of the … Read more...

Raniga D., Amarasingam N., Sandino J., Doshi A., Barthelemy J., Randall K., Robinson S.A., Gonzalez F. & Bollard B. (2024): Monitoring of Antarctica’s fragile vegetation using drone-based remote sensing, multispectral imagery and AI - Sensors, 24(4): 1063 [30 p.]

Vegetation in East Antarctica, such as moss and lichen, vulnerable to the effects of climate change and ozone depletion, requires robust non-invasive methods to monitor its health condition. Despite the increasing use of unmanned aerial vehicles (UAVs) to acquire high-resolution data for vegetation analysis in Antarctic regions through artificial intelligence (AI) techniques, the use of multispectral imagery and deep learning (DL) is quite limited. This study addresses this gap with two pivotal contributions: … Read more...

Islary P., Meher R.K., Biswas S., Basumatary D., Basumatary I.B., Dubey D., Basumatary D. & Daimari R. (2024): Evaluation of anticancer, immunomodulatory and anti-inflammatory potential of antioxidant rich Anzia ornatoides, a lichen species from eastern Himalayan region - South African Journal of Botany, 164: 266–279

The lichen Anzia ornatoides was identified by its morpho-anatomical and chemical features. The hexane, diethyl ether, ethyl acetate, methanol, and water extracts of the lichen were assessed for their antioxidant capacities. The presence of various phyto-compounds of the methanol extract were run through a GC–MS and identified three major compounds viz. methyloxyolivetol, imidazole 2-t‑butyl‑1,4-dimethyl-5-phenyl and benzoic acid 2,4-dihydroxy-3,6-dimethyl-methyl ester. The crude extraction … Read more...

Lee Y., Jang H.-R., Lee D., Lee J., Jung H.-R., Cho S.-Y. & Lee H.-Y. (2024): Graphislactone A, a fungal antioxidant metabolite, reduces lipogenesis and protects against diet-induced hepatic steatosis in mice - International Journal of Molecular Sciences, 25(2): 1096 [16 p.]

Graphislactone A (GPA), a secondary metabolite derived from a mycobiont found in the lichens of the genus Graphis, exhibits antioxidant properties. However, the potential biological functions and therapeutic applications of GPA at the cellular and animal levels have not yet been investigated. In the present study, we explored the therapeutic potential of GPA in mitigating non-alcoholic fatty liver disease (NAFLD) and its underlying mechanisms through a series of experiments using various cell lines … Read more...

Bhagarathi L.K., Da Silva P.N.B. & Subramanian G. (2024): Lichen-host plant specificity on citrus plant species in coastal agroecosystems at No. 63 Benab, Berbice, Guyana - World Journal of Advanced Research and Reviews, 21(1): 2342–2355

This was a preliminary study into host-plant lichen specificity at two coastal agroecosystems sites at No. 63 Benab, Berbice, Guyana. For each of the two sites, sampling plots of 2000 meter square (2000 m2) were demarcated and at 50 m × 40 m study plots were established. Healthy mature trees were identified in each plot to assess the lichen communities host-plant specificity. Twine was used to mark the trunks of 40 healthy individual trees in the North, South, East, and West quadrants (each measuring … Read more...

Clayden S., Driscoll K.E. & Harries H. (2024): The lichen genus Rinodina (Physciaceae) in New Brunswick, Canada - The Canadian Field-Naturalist, 137[2013]: 32–63

Fifteen species of the crustose lichen genus Rinodina are confirmed in New Brunswick, Canada. We report four corticolous species, Rinodina pachysperma, Rinodina populicola, Rinodina septentrionalis, and Rinodina tenuis, and the saxicolous Rinodina tephraspis in the province for the first time. A previous report of Rinodina granuligera is based on a specimen that we have re-identified as Rinodina cinereovirens. We note distinguishing characteristics, habitats, substrata, relative abundance, and biogeographic … Read more...

Bukabayeva Z., Abiyev S., Silybayeva B. & Ivachshenko O. (2024): The impact of climate aridification on rare lichen communities - Biosystems Diversity, 32(1): 142-149

The global diversity of approximately 25,000 lichen species (e.g., from the genera Usnea, Cladonia, and Peltigera), including rare and endangered ones, highlights the importance of preserving their population in the State National Nature Park “Burabay”. The objective of this study was to investigate the distribution of rare lichen species in the territory of the State National Nature Park “Burabay,” located in the Akmola region of Kazakhstan, in the period from 2018 to 2022, with a particular … Read more...
