Abstract The shortage of reliable primary taxonomic data limits the description biological taxa and understanding biodiversity patterns processes, complicating biogeographical, ecological, evolutionary studies. This deficit creates a significant impediment to research conservation planning. crisis are widely recognized, highlighting urgent need for data. Over past decade, numerous countries worldwide have devoted considerable effort Target 1 Global Strategy Plant Conservation (GSPC), which...
The south-eastern Brazil comprises the Atlantic forest (a region mainly characterized by tropical evergreen forest), subtropical forest, mangroves, and scrub sandbanks. Sandy areas are found at sea level, high altitude grassland spots rocky outcrops occur above 2000 m. This is important because richness, diversity, endemism of species, including bryophytes. similarity bryophytes occurring on these different has not been evaluated yet. study aimed to analyse bryofloristic between 12 in...
Abstract The successful implementation of the Convention on Biological Diversity's post‐2020 Global Biodiversity Framework will rely effective translation targets from global to national level and increased engagement across diverse sectors society. Species conservation require policy support measures that can be applied a diversity taxonomic groups, link action outcome goals, both data sets account for context, which species threat abatement restoration (STAR) metric does. To test...
Abstract Antarctic lakes have generally simple periphyton communities when compared with those of lower latitudes. To date, assessment microbial diversity in Antarctica has relied heavily on traditional direct observation and cultivation methods. In this study, sterilized cotton baits were left submerged for two years King George Island Deception Island, South Shetland Islands (Maritime Antarctic), followed by metabarcoding using high-throughput sequencing. DNA sequences 44 taxa belonging to...
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...
Abstract We set out to document the diversity and distribution of bryophytes in Admiralty Bay thereby enable identification patterns local their possible drivers. Combining data extracted from different sources recent collections, we documented presence 63 species. Similarity analyses moss species relation underlying geology ornithogenic influence identified an identical cophenetic correlation coefficient 0.744 for both factors. The Sørensen index was < 0.6, indicating that groups share...
Brazil harbors the highest richness of Convolvulaceae with 424 species recognized mainly distributed in Amazon, Atlantic Forest, Caatinga and Cerrado phytogeographic domains. Seventeen these are representatives Bonamia, ten endemic to country. The aim study was map distribution this group understand its richness, sampling detecting areas endemism, valuable information for conservation. We collected data gathered from herbaria online database. were refined (1) excluding records not at level;...
Polar marine macroalgae thrive in extreme conditions, often displaying geographic isolation and high degree of endemism. The "phycosphere" refers to the zone around algae inhabited by microrganisms. Our study used DNA metabarcoding survey eukaryotic communities associated with seven seaweed species obtained at King George Island (South Shetland Islands, maritime Antarctic), including two Rhodophyta, Chlorophyta three Phaeophyceae. ITS2 region was as a barcode our analysis yielded 77 ASVs...
Background and aims – Mosses comprise avascular terrestrial plants whose relationship with other plant lineages is not yet fully understood. These have a worldwide distribution, but gaps in their distribution been clarified for Brazil. Based on large database, compiled from different sources, we present an overview of the moss Brazil order to assess species richness areas, as well factors that interfere this distribution.Material methods The study area corresponds whole Brazilian territory....
Trindade is a Brazilian oceanic island approximately 1,100 km from the American mainland. The Cyathea Sm. plants were originally considered an endemic species, copelandii Kuhn & Luerssen, but later included in delgadii Sternb. Based on molecular data (trnL-trnF, trnG-trnR and rbcL-accD), morphometric analysis of leaf characters, scanning electron microscopy indusia spores, habitat suitability modeling, present study confirms status C. as synonym delgadii. Intraspecific variation suggests...
This project focuses the process management improvement and increase of coils quality produced on box furnace annealing nº 1 at CSN.The implementation an automation system development automatic analytical control model for thermal cycles provided reliability accuracy.The complicated performance this particular kind metallurgic also could be optimized by tool developed CSN.
