Following on from work on the European bryophyte Red List, the taxonomically and nomenclaturally updated spreadsheets used for that project have been expanded into a new checklist for the bryophytes of Europe.
Methods. A steering group of ten European bryologists was convened, and over the course of a year, the spreadsheets were compared with previous European checklists, and all changes noted. Recent literature was searched extensively. A taxonomic system was agreed, and the advice and expertise of many European bryologists sought.
Key results. A new European checklist of bryophytes, comprising hornworts, liverworts and mosses, is presented. Fifteen new combinations are proposed.
Conclusions. This checklist provides a snapshot of the current European bryophyte flora in 2019. It will already be out-of-date on publication, and further research, particularly molecular work, can be expected to result in many more changes over the next few years.Lien pérenne : DOI : 10.1080/03736687.2019.1694329 Permalink : https://biblio.cbnpmp.fr/index.php?lvl=notice_display&id=147841

Titre : Need for split: integrative taxonomy reveals unnoticed diversity in the subaquatic species of Pseudohygrohypnum (Pylaisiaceae, Bryophyta) Type de document : Imprimé Auteurs : Vladimir E. Fedosov ; Anna V. Shkurko ; Alina V. Fedorova ; Elena Anatolevna Ignatova ; Evgeniya N. Solovyeva ; John C. Brinda ; Mikhail Stanislavovich Ignatov (1956-) ; Jan Kučera Année de publication : 2022 Article en page(s) : 1-69 Catégories : [CBNPMP-Thématique] Bryophytes Mots-clés : Pseudohygrohypnum Résumé : We present an integrative molecular and morphological study of subaquatic representatives of the genus Pseudohygrohypnum (Pylaisiaceae, Bryophyta), supplemented by distribution modelling of the revealed phylogenetic lineages. Phylogenetic analyses of nuclear and plastid datasets combined with the assemble species by automatic partitioning (ASAP) algorithm revealed eight distinct species within the traditionally circumscribed P. eugyrium and P. subeugyrium. These species are therefore yet another example of seemingly widely distributed taxa that harbour molecularly well-differentiated lineages with narrower distribution ranges. Studied accessions that were previously assigned to P. eugyrium form three clearly allopatric lineages, associated with temperate regions of Europe, eastern North America and eastern Asia. Remarkably, accessions falling under the current morphological concept of P. subeugyrium were shown to be even more diverse, containing five phylogenetic lineages. Three of these lineages occur under harsh Asian continental climates from cool-temperate to Arctic regions, while the remaining two, referred to P. subeugyrium s.str. and P. purpurascens, have more oceanic North Atlantic and East Asian distributions. Niche identity and similarity tests suggested no similarity in the distributions of the phylogenetically related lineages but revealed the identity of two East Asian species and the similarity of two pairs of unrelated species. A morphological survey confirmed the distinctness of all eight phylogenetic lineages, requiring the description of five new species. Pseudohygrohypnum appalachianum and P. orientale are described for North American and East Asian plants of P. eugyrium s.l., while P. sibiricum, P. subarcticum and P. neglectum are described for the three continental, predominantly Asian lineages of P. subeugyrium s.l. Our results highlight the importance of nontropical Asia as a center of bryophyte diversity. Phylogenic dating suggests that the diversification of subaquatic Pseudohygrohypnum lineages appeared in late Miocene, while mesophilous species of the genus split before Miocene cooling, in climatic conditions close to those where the ancestor of Pseudohygrohypnum appeared. We speculate that radiation of the P. subeugyrium complex in temperate Asia might have been driven by progressive cooling, aridification, and increases in seasonality, temperature and humidity gradients. Our results parallel those of several integrative taxonomic studies of North Asian mosses, which have resulted in a number of newly revealed species. These include various endemics from continental areas of Asia suggesting that the so-called Rapoport’s rule of low diversity and wide distribution range in subpolar regions might not be applicable to bryophytes. Rather, the strong climatic oscillations in these regions may have served as a driving force of speciation and niche divergence.

Titre : A rare European endemic moss genus Arvernella is discovered in Sakhalin, Russian Far East, where it is also rare Type de document : Imprimé Auteurs : Mikhail Stanislavovich Ignatov (1956-) ; Elena Anatolevna Ignatova ; Oxana I. Kuznetsova Année de publication : 2021 Article en page(s) : 1-7 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Bryophytes Résumé : A molecular phylogenetic analysis revealed that a tiny Amblystegiaceae plant from Sakhalin in the Russian Far East is most closely related to the recently described European endemic genus and species Arvernella microclada. This species is one of the smallest pleurocarpous mosses and it remains known only from a limited area in France, 9000 km from Sakhalin. Sakhalin plant differs from European in longer leaf costa and almost smooth laminal cells versus distinctly prorate in A. microclada, in addition to genetic differences. An equally small East Asian Platydictya fauriei, known from Japan and Corea, differs from the Sakhalin plant in its narrow laminal cells (4–6:1 vs. 1.5–2.5:1). Thus, this Sakhalin plant is described as a new species, Arvernella pisarenkoi Ignatov & Ignatova.

Titre : Schistostega “pollinators” and their attraction Type de document : Électronique Auteurs : Mikhail Stanislavovich Ignatov (1956-) ; Elena Anatolevna Ignatova ; Olga L. Makarova ; Mikhail V. Potapov Année de publication : 2021 Article en page(s) : 451-462 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Bryophytes Mots-clés : Schistostega pennata Résumé : Schistostega is a moss with long shoots terminated by one group of either male or female gametangia. Although it is usually described as dioicous, the protonemata may link such male and female shoots, and most populations comprise homogeneous mixtures of both sexes. Thus, dispersal of male gametes at a certain distance is important for Schistostega to avoid inbreeding. In addition to stochastic dispersal by small arthropods, male gametes of Schistostega attract attention of Acari of the order Sarcoptiformes, suborder Oribatida belonging to families Damaeidae, Oribatulidae, Astegistidae, and Ceratozetidae, and springtails (class Collembola) of the family Entomobryidae, genera Entomobrya and Orchesella. Short videos in supplementary material demonstrate the intentional consumption of antheridial contents of Schistostega by these arthropods in forests in the Moscow Province. Schistostega is likely the first moss where this type of nourishment is demonstrated. These events seem to be not rare, but rather difficult to overwatch in most mosses where antheridia are well protected in bud-like perigonia. Antheridia of Schistostega are scarcely hidden and readily accessible for microarthropods, as well as easy to observe. Permalink : https://biblio.cbnpmp.fr/index.php?lvl=notice_display&id=147771
