A Revised Red List of Bryophytes in Britain
ConservationNews Revised Red List distinguished from Extinct. This Red List uses Extinct in the Wild (EW) – a taxon is Extinct version 3.1 of the categories and criteria (IUCN, in the Wild when it is known to survive only in A revised Red List of 2001), along with guidelines produced to assist cultivation or as a naturalized population well with their interpretation and use (IUCN, 2006, outside the past range.

Mitochondrial Genomes of the Early Land Plant Lineage
Dong et al. BMC Genomics (2019) 20:953 https://doi.org/10.1186/s12864-019-6365-y RESEARCH ARTICLE Open Access Mitochondrial genomes of the early land plant lineage liverworts (Marchantiophyta): conserved genome structure, and ongoing low frequency recombination Shanshan Dong1,2, Chaoxian Zhao1,3, Shouzhou Zhang1, Li Zhang1, Hong Wu2, Huan Liu4, Ruiliang Zhu3, Yu Jia5, Bernard Goffinet6 and Yang Liu1,4* Abstract Background: In contrast to the highly labile mitochondrial (mt) genomes of vascular plants, the architecture and composition of mt genomes within the main lineages of bryophytes appear stable and invariant. The available mt genomes of 18 liverwort accessions representing nine genera and five orders are syntenous except for Gymnomitrion concinnatum whose genome is characterized by two rearrangements. Here, we expanded the number of assembled liverwort mt genomes to 47, broadening the sampling to 31 genera and 10 orders spanning much of the phylogenetic breadth of liverworts to further test whether the evolution of the liverwort mitogenome is overall static. Results: Liverwort mt genomes range in size from 147 Kb in Jungermanniales (clade B) to 185 Kb in Marchantiopsida, mainly due to the size variation of intergenic spacers and number of introns. All newly assembled liverwort mt genomes hold a conserved set of genes, but vary considerably in their intron content. The loss of introns in liverwort mt genomes might be explained by localized retroprocessing events. Liverwort mt genomes are strictly syntenous in genome structure with no structural variant detected in our newly assembled mt genomes. However, by screening the paired-end reads, we do find rare cases of recombination, which means multiple concurrent genome structures may exist in the vegetative tissues of liverworts. -
Bryophyte Recording Handbook C.D
Chapter BRYOPHYTE RECORDING HANDBOOK C.D. Preston T.H. Blackstock S.D.S. Bosanquet M.F. Godfrey M.O. Hill D.T. Holyoak G.P. Rothero A guide to recording mosses and liverworts prepared by members of the British Bryological Society i FOREWORD It is my pleasure as Recording Secretary of the British Bryological Society to commend to you this Handbook, setting out our procedures and recommendations for the future. All the authors of the Handbook are seasoned recorders. The Handbook distils our experience. In 1964, I recorded bryophytes on Harold Whitehouse’s Cambridge excursions. In 2012, I continue to record the bryophytes of Cambridgeshire with great enjoyment. The changes over 47 years are remarkable. Back in the 1960s Plagiochila asplenioides and Rhytidiadelphus triquetrus were common and locally abundant in the boulder-clay woods. Now they are scarce and seen only in small quantity. In those days, pollution-sensitive epiphytes such as Cryphaea heteromalla, Orthotrichum lyellii and O. pulchellum were absent or very rare. Now we see them on most excursions. Sometimes the causes of change are obvious: atmospheric sulfur has decreased dramatically, so the epiphytes have returned. But without good recording both here and in the rest of Europe, we cannot see clearly what is happening or understand Published 2012 by the British Bryological Society its wider significance. Orthotrichum pulchellum, for example, has extended its range www.britishbryologicalsociety.org.uk as well as its frequency. It used to be an ‘Atlantic’ species. Now it is widespread in central Europe. Likewise, Didymodon nicholsonii, long misunderstood on the All rights reserved. -

A Compendium to Marchantiophyta and Anthocerotophyta of Assam, India
Marchantiophyta and Anthocerotophyta of Assam 1 A Compendium to Marchantiophyta and Anthocerotophyta of Assam, India S. K. Singh and H. A. Barbhuiya Botanical Survey of India, Eastern Regional Centre, Lower New Colony, Laitumkhrah, Shillong – 793003, India Correspondences: [email protected] Abstract. A catalogue of 107 species of liverworts (Marchantiophyta) and 8 species of hornworts (Anthocerotophyta), recorded from Assam, India is presented. This includes three new records for India viz., Cololejeunea denticulata (Horik.) S. Hatt., C. inflata Steph., Plagiochila furcifolia Mitt., and three species viz., Cololejeunea desciscens Steph. Colura ari (Steph.) Steph., Lopholejeunea eulopha (Taylor) Schiffn. new to mainland. Twelve species are new record for Eastern Himalayan bryo-geographical territory, 20 species as new to Assam and seven species are endemic to Indian regions. Introduction Marchantiophyta and Anthocerotophyta traditionally known as liverworts and hornworts (Bryophytes) are integral part of any ecosystems and recognized as land dwellers in plant kingdom. They are first colonizer of terrestrial habits after Algae and come after Lichens in plant succession. The taxonomic studies on these groups of plant are far from complete particularly in Indian region. Assam lies in rain shadow of Himalayan ranges and forms part of East Himalayan Bryo- geographical Territory. As far as studies on Marchantiophyta and Anthocerotophyta of the region are concerned, it was initiated by William Griffith in first half of of the nineteenth century who’s work was published in the form of posthumous papers finally culminated into ‘Notulae ad Plantas Asiaticas’ (Griffith, 1849a) wherein he reported many species of cryptogams from earstwhile undivided Assam including ca.18 liverworts of present day Assam. -
