Chowaniec K., Żukowska‑Trebunia A. & Rola K. (2023): Combined efect of acute salt and nitrogen stress on the physiology of lichen symbiotic partners - Environmental Science and Pollution Research, 30: 28192–28205

Nitrogen pollution and excessive salinity are commonly regarded as one of the major environmental concerns in recent decades in many urban environments. Although in urban areas lichens are exposed to both salt and nitrogen stress, no studies have been conducted to date on the simultaneous impact and interaction of these factors on lichen physiology. The aim was to determine the efect of various combinations of NaCl and NH4NO3 doses on the physiology of epigeic lichen Cladonia rei. We also … Read more...

Lalremruata P.C., Singh P. & Lalfakzuala R. (2023): Eleven new records of lichen to the state of Mizoram, Indo-Myanmar biodiversity hot spot region, India - Proceedings of the National Academy of Sciences, India Section B: Biological Sciences, 93(1): 205–211

The paper reports the occurrence of eleven species of crustose and foliose lichens for the first time to the state of Mizoram in northeast India. During the course of lichen exploration in the state of Mizoram, the authors collected lichen specimens from Tawi Wildlife Sanctuary, Mizoram, India. After critical examination and thorough consolation of literature, it revealed that 11 species have been discovered as new additions to the lichen flora of the state. The species include Bacidia connexula … Read more...

In the continuing discovery and structure elucidation of natural xanthone dimers, which are still rarely reported in absolute confguration, three new xanthone dimers, eumitrins I–K (1–3) were isolated from the lichen Usnea baileyi, a rich source of natural xanthone dimers. Their structures were elucidated unambiguously by spectroscopic analyses, including high-resolution electrospray ionization mass spectrometry (HRESIMS), 1D and 2D nuclear magnetic resonance spectroscopy (1D and 2D NMR). … Read more...

Chiva S., Moya P. & Barreno E. (2023): Lichen phycobiomes as source of biodiversity for microalgae of the Stichococcus-like genera - Biologia, 78: 389–397

The term phycobiome was recently introduced to designate all the microalgae (primary or non-primary) associated with lichen symbioses. Abundant non-primary symbiotic microalgae are usually obtained from lichen isolations, confirming that thalli are a source of biodiversity and new species. In this study, microalgae were isolated from thalli of Buellia zoharyi, Ramalina farinacea and Parmotrema pseudotinctorum collected in the Iberian Peninsula and the Canary Islands. Excluding Trebouxia phycobionts, … Read more...

Chen X., Yan D., Yu L. & Zhang T. (2023): An integrative study of mycobiome in different habitats from a High Arctic region: diversity, distribution, and functional role - Journal of Fungi, 9(4): 437 [13 p.]

In the Arctic ecosystems, fungi are crucial for interactions between soil and plants, the cycling of nutrients, and the transport of carbon. To date, no studies have been conducted to thoroughly examine the mycobiome and its functional role in various habitats of the High Arctic region. The aim was to unravel the mycobiome in the nine habitats (i.e., soil, lichen, vascular plant, moss, freshwater, seawater, marine sediment, dung, and marine alga) in the Ny-Ålesund Region (Svalbard, High Arctic) … Read more...

Hardouin M.E. & Hargreaves A.L. (2023): Mapping nationally and globally at-risk species to identify hotspots for (and gaps in) conservation - Proceedings of the Royal Society B: Biological Sciences, 290(1995): 20222307 [11 p.]

Protecting habitat of species at risk is critical to their recovery, but can be contentious. For example, protecting species that are locally imperilled but globally common is often thought to distract from protecting globally imperilled species. However, such perceived trade-offs are based on the assumption that threatened groups have little spatial overlap, which is rarely quantified. We compiled range maps of terrestrial species at risk in Canada to assess the geographic overlap of nationally … Read more...

Stevens C.J., Bell J.N.B., Brimblecombe P., Clark C.M., Dise N.B., Fowler D., Lovett G.M. & Wolseley P.A. (2020): The impact of air pollution on terrestrial managed and natural vegetation - Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 378: 20190317 [18 p.]

Although awareness that air pollution can damage vegetation dates back at least to the 1600s, the processes and mechanisms of damage were not rigorously studied until the late twentieth century. In the UK following the Industrial Revolution, urban air quality became very poor, with highly phytotoxic SO2 and NO2 concentrations, and remained that way until the mid-twentieth century. Since then both air quality, and our understanding of pollutants and their impacts, have greatly improved. Air pollutants … Read more...

(2020): Alkaline air: changing perspectives on nitrogen and air pollution in an ammonia-rich world - Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 378: 20190315 [21 p.]

Ammonia and ammonium have received less attention than other forms of air pollution, with limited progress in controlling emissions at UK, European and global scales. By contrast, these compounds have been of significant past interest to science and society, the recollection of which can inform future strategies. Sal ammoniac (nūshādir, nao sha) is found to have been extremely valuable in long-distance trade (ca AD 600–1150) from Egypt and China, where 6–8 kg N could purchase a human life, … Read more...

Seminara A., Fritz J., Brenner M.P. & Pringle A. (2018): A universal growth limit for circular lichens - Journal of The Royal Society Interface, 15(143): 20180063 [8 p.]

Lichens fix carbon dioxide from the air to build biomass. Crustose and foliose lichens grow as nearly flat, circular disks. Smaller individuals grow slowly, but with small, steady increases in radial growth rate over time. Larger individuals grow more quickly and with a roughly constant radial velocity maintained over the lifetime of the lichen. We translate the coffee drop effect to model lichen growth and demonstrate that growth patterns follow directly from the diffusion of carbon dioxide in the … Read more...

Rolshausen G., Hallman U., Dal Grande F., Otte J., Knudsen K. & Schmitt I. (2020): Expanding the mutualistic niche: parallel symbiont turnover along climatic gradients - Proceedings of the Royal Society B: Biological Science, 287: 20192311 [9 p.]

Keystone mutualisms, such as corals, lichens or mycorrhizae, sustain fundamental ecosystem functions. Range dynamics of these symbioses are, however, inherently difficult to predict because host species may switch between different symbiont partners in different environments, thereby altering the range of the mutualism as a functional unit. Biogeographic models of mutualisms thus have to consider both the ecological amplitudes of various symbiont partners and the abiotic conditions that trigger symbiont … Read more...
