A working checklist of accepted taxa worldwide is vital in achieving the goal developing an online flora all known plants by 2020 as part Global Strategy for Plant Conservation. We here present first-ever liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) that includes 7486 species 398 genera representing 92 families from two phyla. The has far reaching implications applications, including providing a valuable tool taxonomists systematists, analyzing phytogeographic diversity...
Abstract Recent studies have provided evidence for pulses in the diversification of angiosperms, ferns, gymnosperms and mosses as well various groups animals during Cretaceous revolution terrestrial ecosystems. However, such has not been reported so far liverworts. Here we provide new insight into liverwort evolution by integrating a comprehensive molecular dataset with set 20 fossil age constraints. We found relative constant rate generalistic liverworts (Jungermanniales) since Palaeozoic,...
The Zhangpu biota provides a new insight into biodiversity redistribution during the Mid-Miocene Climatic Optimum.
Abstract More than 200 research papers on the molecular phylogeny and phylogenetic biogeography of bryophytes have been published since beginning this millenium. These corroborated assumptions a complex genetic structure morphologically circumscribed bryophytes, raised reservations against many justified species concepts, especially within mosses. However, studies allowed for corrections modifications morphological classification schemes. Several reported that disjunctly distributed...
Some of the evolutionary history land plants has been documented based on fossil record and a few broad-scale phylogenetic analyses, especially focusing angiosperms ferns. Here, we reconstructed relationships among all 706 families using molecular data. We dated phylogeny multiple fossils clock technique. Applying various tests diversification that take into account topology, branch length, numbers extant species as well extinction, evaluated rates through time. also compared these profiles...
Background The Qinghai-Tibetan Plateau (QTP) and its southern southeastern mountain ranges, Himalaya-Hengduan Mountains (HHM), are one of the most extensive habitats for alpine plants in world. How ferns occurring QTP HHM changed their distribution ranges response to Quaternary climatic oscillations remains almost unknown. Methodology Results We employed sequences two chloroplast DNA regions, rps4-trnS trnL-trnF, reconstruct phylogeography Sino-Himalayan fern Lepisorus clathratus, mainly...
Nucleotide sequence variation in the ITS1‐5.8S‐ITS2 region of nuclear ribosomal DNA and trnL‐trnF chloroplast from 49 specimens Bryopteris (Lejeuneaceae) three outgroup species was analyzed using maximum parsimony likelihood. The nrITS exhibits high levels nucleotide variation, whereas is fairly similar among samples same species. Three major clades were found corresponding to Neotropical diffusa filicina, as well gaudichaudii Malagasy region. Morphological characters utilized earlier...
The systematic position of the enigmatic Asiatic liverwort Metzgeriopsis pusilla (Marchantiophyta), single thalloid member largest family leafy liverworts, Lejeuneaceae, was investigated based on sequences rbcL gene and trnL-F region chloroplast DNA, morphology. is not phylogenetically isolated from other taxa as previously suggested, but nested within Cololejeunea. two genera share many morphological features, especially in sporophyte generation, which newly described. Cololejeunea are...
Recognition and formalization of morphologically cryptic species is a major challenge to modern taxonomy. An extreme example in this regard the Holarctic Porella platyphylla s.l. (P. plus P. platyphylloidea). Earlier studies demonstrated presence three isozyme groups two molecular lineages. The present investigation was carried out elucidate diversity distribution its main clades, evaluate evidence for one vs. several species.We obtained chloroplast (atpB-rbcL, trnL-trnF) nuclear ribosomal...
Background Lejeunea is a largely epiphytic, subcosmopolitan liverwort genus with complex taxonomic history. Species circumscriptions and their relationships are subject to controversy; biogeographic history diversification through time unknown. Methodology Results We employed sequences of two chloroplast regions (trnL-trnF, rbcL) the nuclear ribosomal ITS region 332 accessions explore phylogeny Harpalejeunea-Lejeunea-Microlejeunea complex. forms well-supported clade that splits into main...
Abstract Polyploidy is widely considered as a major process in the evolution of plants but accumulation polyploid species diversity still controversial. Some recent studies proposed increased extinction risk neopolyploids compared with their diploid ancestors. The high proportion ferns expected to be formed mainly by neopolyploids, whereas paleopolyploid are predicted clustered clades founded whole genome duplications. Here, we test this prediction exploring polyploidy derived fern family...
Introduction Half a century since the creation of International Association Bryologists, we carried out review to identify outstanding challenges and future perspectives in bryology. Specifically, have identified 50 fundamental questions that are critical advancing discipline.Methods We adapted deep-rooted methodology horizon scanning key research foci. An initial pool 258 was prepared by multidisciplinary international working group 32 bryologists. A series online surveys completed broader...
Upper montane oak forests in the Cordillera de Talamanca show a high diversity of bryophyte species and great diversification microhabitats. A complete inventory six hectare forest yielded 206 species: 100 mosses, 105 hepatics, one hornwort. Based on similarities composition microhabitats cluster into three main groups: 1) floor habitats (including tree base), 2) phyllosphere, 3) other epiphytic habitats. The contribution to total richness is much higher than lower elevational belts....
Tropical forests contain the majority of extant plant diversity and their role as a cradle and/or museum biodiversity is an important issue in our attempts to assess long-term consequences global climate change for terrestrial biomes. Highly diverse groups liverworts are often ignored but extremely common element rainforests, thus evolution may shed light on ecological robustness rainforest biomes fluctuations. We record remarkable constant accumulation through time most species-rich family...
