Lu H.-., Brooker R., Song L., Liu W.-., Sack L., Zhang J.-. & Yu F.-. (2020): When facilitation meets clonal integration in forest canopies, New Phytologist, 225(1): 135-142

Few studies have explored how – within the same system – clonality and positive plant–plant interactions might interact to regulate plant community composition. Canopy-dwelling epiphytes in species-rich forests provide an ideal system for studying this because many epiphytic vascular plants undertake clonal growth and because vascular epiphytes colonize canopy habitats after the formation of nonvascular epiphyte (i.e. bryophyte and lichen) mats. We investigated how clonal integration of seven … Read more...

Ramírez N., Vinchira-Villarraga D., Rabiey M., Sigurbjörnsdóttir M.A., Heidmarsson S., Vilhelmsson O. & Jackson R.W. (2025): Exploring the exclusive isolation of Pseudomonas syringae in Peltigera lichens via metabolite analysis and growth assays, Environmental Microbiology, 27: e70057 [12 p.]

The specific association of the potentially plant-pathogenic Pseudomonas syringae with Peltigera lichens raises questions about the factors driving this host specificity. To explore this, the metabolic profile of seven lichen species belonging to three genera (Cladonia, Peltigera and Stereocaulon) was analysed using LC-MSMS. In addition, we assessed the growth of P. syringae strains in media supplemented with extracts from each lichen species. This revealed that Peltigera exhibits lower metabolite … Read more...

Fang H., Labandeira C.C., Yiming Ma Y., Zheng B., Ren D., Wei X., Liu J. & Wang Y. (2020): Lichen mimesis in mid-Mesozoic lacewings, eLife, 9: e59007

Animals mimicking other organisms or using camouflage to deceive predators are vital survival strategies. Modern and fossil insects can simulate diverse objects. Lichens are an ancient symbiosis between a fungus and an alga or a cyanobacterium that sometimes have a plant-like appearance and occasionally are mimicked by modern animals. Nevertheless, lichen models are almost absent in fossil record of mimicry. Here, we provide the earliest fossil evidence of a mimetic relationship between the moth … Read more...

Kidron G.J. & Starinsky A. (2019): Measurements and ecological implications of non-rainfall water in desert ecosystems—A review, Ecohydrology, 12(6): e2121

The current review focuses on the contribution of non-rainfall water (NRW) to arid and semiarid regions (with a focus on the Negev), where NRW may provide a constant source of water that may facilitate the survival of different organisms, especially microorganisms. Factors that determine the amounts of NRW and the contribution of NRW to plants and organisms are discussed. Nevertheless, although important, significant variation exists regarding the amounts of NRW, which may stem from improper use … Read more...

Fatima A., Ramdani M. & Lograda T. (2019): Relationship between lichen diversity and air quality in urban region in Bourdj Bou Arriridj, Algeria, Biodiversitas, 20(8): 2329-2339

The lichenic biodiversity can be an excellent instrument for measuring air quality biomonitoring in urban and industrial areas. Two bio-monitoring techniques were used to assess and map the levels of air quality in Bordj Bou Arreridj region (BBA), an urban area located in Eastern Algeria, and to identify species sensitive to air pollution. The first one was based on the diversity and abundance of epiphytic lichens, while the other technique was using two bio-indication indices. Epiphytic lichens … Read more...

Heatwole H. & Miller W.R. (2019): Structure of micrometazoan assemblages in the Larsemann Hills, Antarctica, Polar Biology, 42: 1837–1848

Assemblages of terrestrial biotas in Antarctica have low species-diversity, taxonomic breadth, and number of trophic links and may provide insights not only into adaptation to extreme environments, but also into an understanding of community structure and dynamics not readily achieved by studying more complex, less tractable, systems. To this end, we collected core-samples of soils and the Bryosystem in the Larsemann Hills, Antarctica, and extracted their contained micrometazoans (tardigrades, rotifers, … Read more...

(+)-Usnic acid, a product of secondary metabolism in lichens, has displayed a broad range of biological properties such as antitumor, antimicrobial, antiviral, anti-inflammatory, and insecticidal activities. Interested by these pharmacological activities and to tap into its potential, we herein present the synthesis and biological evaluation of new usnic acid enaminone-conjugated 1,2,3-triazoles 10-44 as antimycobacterial agents. (+)-Usnic acid was condensed with propargyl amine to give usnic acid … Read more...

Martínez Pastur G.J., Rosas Y.M., Toro Manríquez M., Huertas Herrera A., Miller J.A., Cellini J.M., Barrera M.D., Peri P.L. & Lencinas M.V. (2019): Knowledge arising from long-term research of variable retention harvesting in Tierra del Fuego: Where do we go from here?, Ecological Processes, 8(1): 24

Nothofagus pumilio forests in Tierra del Fuego are the southernmost forests in the world, where extreme climate conditions represent a challenge to attain sustainable forest management. Retention forestry was proposed as an alternative to increase the species conservation in managed stands. Here, we synthetized results related to the implementation of a variable retention harvesting based on a combination of aggregate patches and dispersed retention during the last 18 years comparing with other silviculture … Read more...
