Doležal J., Dančák M., Kučera J., Majeský L., Altman J., Řeháková K., Čapková K., Vondrák J., Fibich P. & Liancourt P. (2022): Fire, climate and biotic interactions shape diversity patterns along an Afrotropical elevation gradient - Journal of Biogeography, 49: 1248–1259

Aim: Untangling multiple drivers influencing biodiversity along elevation gradients is necessary for predicting the consequences of climate change on mountain communities. We examine the direct and indirect effects of macroclimate, edaphic conditions, fire frequency and putative biotic interactions on species richness and abundance of co-occurring primary producers on Mount Cameroon. Location: Mount Cameroon, Cameroon. Taxon: vascular plants, bryophytes and lichens, and soil microbial phototrophs. Methods: … URL EndNote Read more...

Miranda-González R., Epitacio-Joaquin G., Tehler A., Téllez N.S. & Herrera-Campos M.A. (2022): Roccella ramitumidula (Roccellaceae), a new species from the tropical dry forest of Mexico - Bryologist, 125(3): 477–484

The new species Roccella ramitumidula is described from a tropical dry forest in the Pacific Coast of Mexico. The new species is characterized by fertile thalli, saxicolous habit, irregularly swollen branches and erythrin and lecanoric acid as lichen products. It differs from R. decipiens by its narrower and longer ascospores, irregularly swollen branches, uneven surface, and smaller branches. Sequences of the genetic markers ITS, nuLSU and RPB2 from the new species were added to a phylogenetic … URL EndNote Read more...

Lynikienė J., Gedminas A., Marčiulynas A., Marčiulynienė D. & Menkis A. (2022): Can Larix sp. Mill. provide suitable habitats for insects and lichens associated with stems of Picea abies (L.) H. Karst. in northern Europe? - Diversity, 14: 729 [22 p.]

Recent observations suggest that climate change affects the growth conditions and range of tree species distribution in Europe. This may also have a major effect on communities of different organisms associated with these tree species. We aimed to determine whether Larix sp. could provide suitable habitats to insects and lichens associated with P. abies to conserve their biodiversity under climate change. The study sites were 10 Larix sp. and 10 P. abies forest stands in Lithuania. Both living … URL EndNote Read more...

Ndhlovu N.T., Solhaug K.A., Minibayeva F. & Beckett R.P. (2022): Melanisation in boreal lichens is accompanied by variable changes in non-photochemical quenching - Plants, 11(20): 2726 [13 p.]

Lichens often grow in microhabitats where they absorb more light than they can use for fixing carbon, and this excess energy can cause the formation of harmful reactive oxygen species (ROS). Lichen mycobionts can reduce ROS formation by synthesizing light-screening pigments such as melanins in the upper cortex, while the photobionts can dissipate excess energy radiationlessly using non-photochemical quenching (NPQ). An inherent problem with using fluorimetry techniques to compare NPQ in pale and … URL EndNote Read more...

Fernández-Prado N., Aragón G., Prieto M., Benítez Á. & Martínez I. (2022): Differences in epiphytic trunk communities in secondary forests and plantations of southern Ecuador - Forestry, 2022: cpac034 [17 p.]

Deforestation is the most important cause of biodiversity loss in tropical ecosystems. Epiphytic species, lichens and bryophytes, are very sensitive to environmental changes, including those produced by conversion of primary forests into secondary vegetation. However, little is known about the differences between different secondary forests and plantations regarding the epiphytic biota. We compared epiphytic communities among different secondary forests and non-native plantations in southern … URL EndNote Read more...

Garrido-Benavent I., Molins A. & Barreno E. (2022): Genetic variation in the symbiont partners in the endangered macrolichen Seirophora villosa (Teloschistaceae: Ascomycota) - Botanical Journal of the Linnean Society, 199(4): 816–829

The decline observed in many populations of highly sensitive lichens has led to the inclusion of some species on regional Red Lists, but this has seldom been accompanied by an examination of the genetic variation of the fungal and algal symbiotic partners. Here, the red-listed epiphytic lichen Seirophora villosa was surveyed in 14 Mediterranean coastal populations to examine the genetic diversity of both partners. The geographical distribution of four-locus haplotypes followed the same trend … URL EndNote Read more...

Lücking R., Moncada B., Widhelm T.J., Lumbsch H.T., Blanchon D.J. & de Lange P.J. (2022): The Sticta filix - Sticta lacera conundrum (lichenized Ascomycota: Peltigeraceae subfamily Lobarioideae): unresolved lineage sorting or developmental switch? - Botanical Journal of the Linnean Society, 199(3): 706–727

We assessed the status of two New Zealand endemic morphodemes in the genus Sticta, currently treated as two separate taxa, Sticta filix and Sticta lacera. Both are green-algal lichens with a distinct stipe that grow in forested habitats and are suitable indicators of the indigenous vegetation health in forest ecosystems in New Zealand. They exhibit different morphologies and substrate ecologies: S. filix forms rather robust thalli, often on exposed trunks of phorophytes, with erect stems distinctly … URL EndNote Read more...

Borgato L., Ertz D., Van Rossum F. & Verbeken A. (2022): The diversity of lichenized trentepohlioid algal (Ulvophyceae) communities is driven by fungal taxonomy and ecological factors - Journal of Phycology, 58: 582–602

Trentepohliales are a group of both free-living and lichenized algae, with most diversity occurring in tropical regions. Recent studies showed that the abundance of lichens with a trentepohlioid photobiont has been increasing in temperate habitats, probably because of global warming, which makes them an interesting study case. A detailed molecular study of the diversity of lichenized Trentepohliales, epiphytic as well as epilithic, was performed in three forests of north-western Europe.

Forty-four new lichen species and one lichenicolous fungus have been identified as a result of studies of the lichen biota of the Franz Josef Land archipelago. Bryocaulon hyperboreum was reported for the first time from Russia. Gyalecta hypoleuca and Umbilicaria maculata were first identified in the Arctic.

Lichens can survive and cope with unsufficient water supply resulting in low in-trathalline relative water content.Under such conditions, photosynthesis is negatively affected by different degree of dehydration. In our study, fully hydrated samples of Xanthoria elegans, Umbilicaria decussata and Usnea aurantiaco-atra were light-accli-mated and during following desiccation from a fully hydrated to dry state, steady-statechlorophyll fluorescence (FS), effective quantum yield … URL EndNote Read more...
