Tufan-Cetin O., Cengiz A., Gultekin Z.N., Kahraman S., Polat B., Koc S. & Cetin H. (2023): Total phenolic and flavonoid contents of oakmoss lichen Evernia prunastri extracts and their insecticidal activities against larvae of two vector mosquitoes, Aedes aegypti and Culex pipiens - International Journal of Tropical Insect Science , 43: 1355–1363

Aedes aegypti L. and Culex pipiens L. are among the world’s most common and medically important mosquitoes (Diptera: Culicidae). Each year, millions of people are infected with pathogens transmitted by these mosquitoes and thousands of people die from mosquito-borne diseases. Although chemical insecticides are widely used for vector control, most of them are highly toxic to the environment and human health. The harmful effects of chemical pesticides have led scientists to search for the … URL EndNote PDF Read more...

Tenwolde K.J. & Wiersma Y.F. (2023): Drivers of lichen diversity and abundance on trailside benches in the City of St. John’s, Newfoundland and Labrador, Canada - Evansia, 40(2): 54–70

We explored the drivers of lichen taxonomic diversity and lichen abundance on wooden trailside benches within the city of St. John’s, Newfoundland and Labrador, to better understand lichen colonization of wooden structures. We examined three variables including the age of each bench, the distance of each bench from the nearest tree with lichens, and the distance of each bench from the nearest road. Multivariate analyses and model selection using AIC revealed that bench age and distance … URL EndNote Read more...

Szczepańska K., Kukwa M., Guzow-Krzemińska B. & Urbaniak J. (2023): New and rare lichens of the family Megasporaceae discovered in Poland - Phytotaxa, 598(2): 133–144

Based on a revision of historic herbarium material and recently collected specimens, six lichenized fungi of the family Megasporaceae have been identified. Four of them, Aspicilia verrucigera, Oxneriaria supertegens, Sagedia mastrucata and S. zonata are reported for the first time from Poland. Also, we present new localities for two species, Aspicilia goettweigensis and A. polychroma, that have been rarely reported in the country. The characteristics of all these species, as well as their ecology … URL EndNote PDF Read more...

Mohamed E., Loudiki M. & El Gharmali A. (2023): Bioaccumulation and sources identification of atmospheric metal trace elements using lichens along a rural–urban pollution gradient in the Safi-Essaouira coastal area - Chemistry and Ecology, 39(2): 107–122

Atmospheric contamination by metallic trace elements emitted by various human activities constitutes an important threat to human and environmental health. This study aims to determine metal accumulation and the sources of air metallic pollution in the Safi urban-industrial area using lichens as biomonitors. Ten trace elements (As, Cd, Co, Cr, Cu, Ni, Pb, Ti, V and Zn) concentrations and 206Pb/207Pb and 208Pb/207Pb isotopic ratios were analyzed by ICP-MS in four lichen species: Xanthoria Parietina, … URL EndNote PDF Read more...

Rom J., Haas F., Heckmann T., Dremel F., Fleischer F., Altmann M., Stark M. & Becht M. (2023): Establishing a record of extreme debris flow events in a high Alpine catchment since the end of the Little Ice Age using lichenometric dating - Geografiska Annaler: Series A, Physical Geography, 105(1): 47–63

Establishing a record of large debris flow events in high Alpine areas prior to the availability of high resolution remote sensing data can be very challenging. In this study, we investigate the debris flow activity in two tributary valleys of the Horlachtal catchment in Tyrol, Austria between the end of the Little Ice Age at about 1850 and the first available area wide aerial images from 1947. To accomplish this, we calculated a local lichenometric calibration curve using the long axis diameters … URL EndNote PDF Read more...

Hoffman J.R., Karol K.G., Ohmura Y., Pogoda C.S., Keepers K.G., McMullin R.T. & Lendemer J.C. (2023): Mitochondrial genomes in the iconic reindeer lichens: Architecture, variation, and synteny across multiple evolutionary scales - Mycologia, 115(2): 187–205

Variation in mitochondrial genome composition across intraspecific, interspecific, and higher taxonomic scales has been little studied in lichen obligate symbioses. Cladonia is one of the most diverse and ecologically important lichen genera, with over 500 species representing an array of unique morphologies and chemical profiles. Here, we assess mitochondrial genome diversity and variation in this flagship genus, with focused sampling of two clades of the “true” reindeer lichens, Cladonia … URL EndNote PDF Read more...

Wang Z., Wu B., Ma Z., Zhang M., Zeng H. & Yang L. (2023): Spectral determinants of biological soil crusts in the Gurbantungut Desert - International Journal of Remote Sensing, 44(7): 2273–2293

As thick crustal layers form on dryland surfaces, they affect the spectral information that is originally dominated by sand or rock. The spectral characteristics of organic matter replace the mineral elements as prominent features. In this case, the growth patterns and spectral characteristics of biological soil crusts (BSCs) can be observed. Satellite spectral data have been used for BSC spatial information extraction. However, the dynamic changes in BSCs can affect the spectra. Two aspects … URL EndNote PDF Read more...

Kasanke S.A., Walker D.A., Chapin III F.S. & Mann D.H. (2023): Plant succession on glacial moraines in the Arctic Brooks Range along a >125,000-year glacial chronosequence/toposequence - Arctic, Antarctic, and Alpine Research, 55(1): 2178151 [22 p.]

Widespread glacial retreat is now occurring in many arctic mountain ranges, yet little is known about primary succession following deglaciation in these settings. Newly created habitats could provide refugia for flora and fauna whose ranges are threatened elsewhere by rapid warming. To assess vegetation responses to glacial retreat in an arctic–alpine setting, we first describe plant community development on two recently deglaciated moraines in the Brooks Range. We then compare these recent … URL EndNote Read more...

Fang J., Mamut R., Wang L. & Anwar G. (2023): De novo mitochondrial genome sequencing of Cladonia subulata and phylogenetic analysis with other dissimilar species - PLoS ONE, 18(5): e0285818 [19 p.]

In this study, the complete mitochondrial genome of Cladonia subulata (L.) FH Wigg was sequenced and assembled and then compared with those of other Cladonia species. The mitogenome of Cladonia subulata, the type species of Cladonia, consisted of a circular DNA molecule of 58,895 bp 44 genes (15 protein-coding genes, 2 rRNA genes, and 27 tRNA genes). The base composition had shown an obvious AT preference, and all 27 tRNA genes formed a typical clover structure. Comparison with other 7 Cladonia … URL EndNote PDF Read more...

Fayyaz I., Knudsen K., Zulfqar R., Afshan N.S., Iftikhar F., Niazi A.R., & Khalid A.N. (2023): Taxonomic and phylogenetic study of genus Sarcogyne (Acarosporales, Acarosporaceae) reveals two new species from Pakistan - Mycological Progress , 22: 45 [9 p.]

Two new species, Sarcogyne crispula and S. pakistanensis are described and illustrated from Pakistan. Sarcogyne crispula is similar to S. praetermissa. Both have lecideine apothecia with smooth melanized margins which curl inward above the apothecial disc and grow on calcareous rock, but they difer especially in S. crispula having larger apothecia (2–3 mm wide vs. usually less than 1 mm) with thinner margins (50–70 vs. 70–120 μm) as well as difering in nrITS and mtSSU regions. Sarcogyne … URL EndNote PDF Read more...
