Comparative transcriptome analysis suggests convergent evolution of desiccation tolerance in Selaginella species

open access: yesBMC Plant Biology, 2020
Background Desiccation tolerant Selaginella species evolved to survive extreme environmental conditions. Studies to determine the mechanisms involved in the acquisition of desiccation tolerance (DT) have focused on only a few Selaginella species.

First record of Selaginella from Miocene amber [PDF]

open access: yesFossil Record
Among extant lycophytes, Selaginella (Selaginellaceae, spike mosses) is the most species-rich genus, with over 700 described species. The evolutionary history of this lycophyte genus dates back to the Carboniferous or even Devonian; however, amber ...

Extreme plastid RNA editing may confound phylogenetic reconstruction: A case study of Selaginella (lycophytes)

open access: yesPlant Diversity, 2020
Cytidine-to-uridine (C-to-U) RNA editing is common in coding regions of organellar genomes throughout land plants. In most cases RNA editing alters translated amino acids or creates new start codons, potentially confounds phylogenetic reconstructions. In

Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway

open access: yesBoreas, EarlyView.
The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant
