A major natural route of dispersal to Antarctica is often assumed be atmospheric transport, although few studies have documented this in detail. Aerial very challenging as the continent geographically remote from other land areas and isolated by circumpolar vortex. Detailed information about aerial routes which microorganisms arrive circulate generally lacking, aerobiological focused on eukaryotes those that predominantly relied traditional morphological identification. Recent advances...
Molecular phylogenetic reconstructions support the monophyly of Pylaisiaceae. The family includes Calliergonella Loeske, Homomallium (Schimp.) Pseudohygrohypnum Kanda, Pylaisia Schimp., 2 further genera formerly placed in Hypnaceae, Ectropothecium Mitt. and Vesicularia (Müll.Hal.) Müll.Hal., as well several species Hypnum Hedw. recently considered to belong Stereodon (Brid.) Rchb. Calliergonella, Ectropothecium, Pylaisia, Vesicularia, are monophyletic based on present data, whereas is...
Abstract The few Antarctic studies to date have applied metabarcoding in Antarctica primarily focused on microorganisms. In this study, for the first time, we apply high-throughput sequencing of environmental DNA investigate diversity Embryophyta (Viridiplantae) present soil samples from two contrasting locations Deception Island. was a relatively undisturbed site within an Specially Protected Area at Crater Lake, and second heavily human-impacted Whalers Bay. obtained 84% reads represented...
Abstract In Antarctica, the genus Bartramia has been restricted to a single polymorphic species, B. patens . Its status as separate species or subspecies of Northern Hemisphere ithyphylla was debated. present paper, we combine analyses chloroplast ( trn S– rps 4– T– L– F region) and nuclear ITS sequences with reinvestigation morphological characteristics infer identity Antarctic Phylogenetic Automatic Barcode Gap Discovery (ABGD) delimitation indicate that diversity in Antarctica...
With 29 Km2, the Fildes Peninsula is largest ice free area in King George Island and probably Antarctica. The region house of six permanent bases including only airport South Shetlands, which led to impacts on its original landscape vegetation. In recognition for need protect natural values, an Antarctic Specially Protected Area (ASPA 125) was established region. Focused mostly protecting fossils, ASPA also plays a role vegetation but so far, management plan does not contain list moss...
Located of the east coast Fildes Peninsula, South Ardley Island, at King George Ostrov Geologov (Geologist Islands) is a small island with 0.25 miles long. It only had one plant record published so far. We have conducted extensive fieldwork on site and provide here comprehensive checklist key for moss species occurring island. Despite its size, theislandcontains about 35% all theFildes Peninsula flora, six new records were found. The pristine state due to relative isolation, presence avian...
Abstract The occurrence of species in both polar regions (bipolarity) is a common phenomenon the Antarctic flora. Considering high morphological variation due to extreme conditions, use molecular tools indispensable for testing whether Arctic and populations indeed belong same species. However, few phylogeographic studies bipolar bryophytes have been conducted so far, especially when comparing variation. Here, we assess bipolarity intraspecific Roaldia revoluta , strictly pleurocarpous...
