The discovery of exceptionally well preserved fossils of lacustrine and terrestrial organisms from the McMurdo Dry Valleys sector of the Transantarctic Mountains are reported, providing novel constraints for the timing and amplitude of middle-Miocene cooling in Antarctica and revealing the ecological legacy of this global climate transition.
An annotated checklist of the mosses of Europe and Macaronesia
The moss flora of Europe and Macaronesia comprises 278 genera, 1292 species, 46 subspecies and 118 varieties, which is strongly influenced by results of modern molecular methods, but there are still many remaining uncertainties, even at family level.
Sex ratio patterns in dioicous bryophytes re-visited
The present data do not support the generalization that the most strongly female-biased sex ratios among dioicous bryophytes occur in 'extreme environments', and it is suggested here that phylogenetic history may explain observed species-wide sex ratios better than current habitat conditions in at least some cases.
Cryptic speciation, habitat differentiation, and geography in Hamatocaulis vernicosus (Calliergonaceae, Bryophyta)
A molecular study of the wetland pleurocarpous moss Hamatocaulis vernicosus (Mitt.) Hedenäs, based on the ITS region, the trnL-trnF region, and rpl16 revealed two cryptic species. One of these is…

An annotated checklist of bryophytes of Europe, Macaronesia and Cyprus
This checklist provides a snapshot of the current European bryophyte flora in 2019, and further research, particularly molecular work, can be expected to result in many more changes over the next few years.
Circumscription, classification, and taxonomy of Amblystegiaceae (Bryopsida) inferred from nuclear and chloroplast DNA sequence data and morphology
The sporophytic features of Anacamptodon, which contrast with those of all the other members of Amblystegiaceae, are interpreted as adaptations to an epiphytic habitat and suggest, together with other recent taxonomic works in Hookeriales, that characters related to sporophyty specializations are among the most homoplastic.
A farewell to Tortella bambergeri (Pottiaceae) as understood over the last decades
Molecular sequence data provide convincing evidence that Tortella bambergeri (Schimp.) Broth., as understood over the last three decades, consists of two species. On the other hand, a careful…

The calibrated phylogeny indicates that Homalothecium has undergone a fast radiation during the last 4 Myr, which is consistent with the low levels of morphological divergence among sibling species, and suggests that species distributions result from rare instances of dispersal and subsequent sympatric diversification.
