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 … 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 … 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 … 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 … 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 … Read more...
