Yiau J.Y.T., Ang C.W. & Santiago K.A.A. (2026): Metabolite profile analysis and antimicrobial properties of Usnea pectinata, Parmotrema tinctorum and Parmotrema crinitum in Bukit Larut, Perak, Malaysia: A case study, The Microbe, 12: 100758 [5 p.]

This study investigated the antimicrobial activities and metabolic profiles of the lichens Usnea pectinata, Parmotrema tinctorum and Parmotrema crinitum from Bukit Larut, Malaysia. Acetonic lichen extracts were prepared and screened against Staphylococcus aureus, Escherichia coli and Candida albicans using the Kirby-Bauer disk diffusion assay. Only U. pectinata extracts inhibited S. aureus, likely imparted by the antibacterial compound usnic acid. Liquid chromatography mass spectrometry (LCMS) analysis, … Read more...

Hensel A. & Ramtvedt E.N. (2026): Differences in surface–subsurface temperature regimes and soil moisture between vegetation types across a boreal-alpine ecotone, CATENA, 272: 110337 [11 p.]

The boreal-alpine ecotone is distinguished by abrupt vegetation shifts along short altitudinal gradients, with climate warming driving treeline shifts upwards and northwards. In this study, we examine the hypothesis that distinct vegetation types present within this ecotone exhibit significant differences in surface–subsurface temperature regimes, as well as in soil moisture levels. This was done by measuring subsurface, surface and above-surface temperatures and soil moisture along a boreal-alpine … Read more...

Beaulieu C., Coops N.C., Morin-Bernard A., Côté S.D. & Achim A. (2026): Quantifying changes in annual lichen volume for woodland caribou in Newfoundland using Landsat time series, International Journal of Applied Earth Observation and Geoinformation, 152: 105444 [17 p.]

Terrestrial and arboreal lichen are the primary winter food source of the threatened boreal ecotype of woodland caribou (Rangifer tarandus caribou). Despite its essential role, lichen biomass, a key factor of caribou habitat suitability, remains poorly quantified in forested landscapes, limiting effective habitat management and recovery planning. Our objective was to estimate lichen volume across two Newfoundland (Canada) boreal caribou herd ranges (Gros Morne and Gaff Topsails) using vegetation-specific … Read more...

Rudski B.Z., Deering J., McKee M.D. & Reznikov N. (2026): Statistical analyses of feature orientation in 3D reticulate biological assemblies , Materials Today Advances, 31: 100869 [12 p.]

Biological structure and function are closely linked, with functional clues often concealed within intricate three-dimensional details of the structure. Such details in branching, fibrous and porous biological assemblies can be investigated at multiple scales using volumetric imaging. However, 3D visualisations alone do not provide a quantitative assessment of specimen architecture. Directional quantification of structural attributes such as texture — reflecting orientation and co-alignment (anisotropy) … Read more...

Bélanger-Jumeau O.P., Ulkatcho First Nation & Harvey J.E. (2026): Recent burns provide some summer forage for threatened southern mountain caribou and may influence forage overlap with moose and bears , Journal of Pyrogeography, 3(1): 100013 [13 p.]

The Ulkatcho people of west-central British Columbia have co-existed with caribou since time immemorial. Moose in contrast became abundant in Ulkatcho territory during the early 1900's. Recent declines in caribou populations have been linked to increases in moose abundance and increased encounters between caribou and predators. Shifts in wildfire regimes may cause habitat alteration in these multiple prey – multiple predator ecosystems. The availability of forage after wildfire may therefore be … Read more...

Çevik U., Çelik N., Uzun K.K., Çelik A., Koz B., Özen S.A., Yeşilkanat C.M., Hacısalihoğlu A., Özkalaycı F. & Kaya S. (2026): Long-term decline of Chernobyl-derived 137Cs in mosses and lichens from the Eastern Black Sea region of Türkiye, Journal of Environmental Radioactivity, 298: 108104 [11 p.]

This study presents the third consecutive assessment of ¹³⁷Cs activity concentrations in the same 50 moss (7 species) and lichen (2 species) sampling points in Ordu province, Türkiye, one of the most heavily contaminated areas following the Chernobyl accident. Samples were collected from exactly the same locations used in the 1997 and 2007 studies and analyzed by high‑resolution gamma spectrometry. In 2025, detectable ¹³⁷Cs was found in 14 of 30 moss sites (47%) and 3 of 20 lichen sites … Read more...

Chethan Prasad M., Pandi V., Asundi V.S., Pujari A. & Shivanna R. (2026): The role of lichens in biomonitoring of pollution, climate change and sea level rise in tropics: Insights from India and beyond , Ecological Indicators, 189: 115204 [10 p.]

Tropical coastal ecosystems are facing rapid environmental change resulting from global climate switch, sea level rise, change in weather and anthropogenic pressures. In this context, reliable ecological indicators are critical for assessing ecosystem response and susceptibility. Lichens with their extreme sensitivity to microclimatic-macroclimatic variation and atmospheric stress have been used as bioindicators in terrestrial ecosystems for a long time. Their ability as coastal climate change indicators, … Read more...

Kumar V. & Uniyal S.K. (2026): Lichen-insect associations and the first record of a moth mimicking the umbilicate lichen Lasallia pertusa (Umbilicariaceae) in the Western Himalaya, India, Arthropod-Plant Interactions, 20: 55 [8 p.]

The interactions between moths and lichens are diverse and have long fascinated ecologists and evolutionary biologists. Lichens play multiple roles in these associations, serving as a food source, shelter, a substrate for concealment, and a background that may facilitate camouflage or deceptive resemblance. Background matching with lichens is a well-known anti-predator strategy in Lepidoptera, where wing patterns often imitate lichen textures. However, most documented cases involve other lichens, … Read more...

Pradhan T., Palit K., Chakraborty S., Rath S., Dash H.R. & Das S. (2026): Microbial bioindicators for multidimensional assessment of environmental alterations and ecosystem functioning, World Journal of Microbiology and Biotechnology, 42: 376 [36 p.]

Anthropogenic stressors leading to environmental pollution and subsequent climate change are emerging as a global concern. Consequently, the quality of the major environmental components, such as air, water, and soil is deteriorating, adversely affecting the overall ecosystem functioning. In this regard, bioindicators play a vital role in assessing environmental alterations and their implications for the functional integrity of ecosystems. Microbial bioindicators exhibit noticeable changes in physiological, … Read more...

Alves R.P., Weber B., Barbosa C.G.G., Clark A.T., Victoria F.C., de Albuquerque M.P. & Pereira A.B. (2026): Alterations of cryptogam communities over one decade of time on King George Island, Antarctica, Polar Biology, 49: 79 [16 p.]

Antarctica’s ice-free areas are mainly colonized by cryptogamic communities, which are known to be sensitive indicators of environmental change. Despite numerous monitoring-related studies, published research on medium-term cryptogam cover changes is limited. With this study, we aimed to investigate compositional and structural changes in cryptogamic communities over a decade near the Polish Arctowski Antarctic Station. Here, a phytosociological approach was used to assess species diversity, coverage, … Read more...
