The InBIO Barcoding Initiative Database: DNA barcodes of Iberian Plecoptera 01

ABSTRACT: The use of DNA barcoding allows unprecedented advances in biodiversity assessments and monitoring schemes of freshwater ecosystems, nevertheless it requires the construction of comprehensive reference collections of DNA sequences that represent the existing biodiversity. Plecoptera are considered particularly good ecological indicators and one of the most endangered groups of insects, but very limited information on their DNA barcodes is available in public databases. Currently, less than 50% of the Iberian species are represented in BOLD. The InBIO Barcoding Initiative (IBI) Plecoptera 01 dataset contains records of 71 specimens of Plecoptera. All specimens have been morphologically identified to species level, and belong to 29 species in total. This dataset contributes to the knowledge on the DNA barcodes and distribution of Plecoptera from Iberian Peninsula, and it is one of the IBI database public releases that makes available genetic and distribution data for a series of taxa. The species represented in this dataset correspond to an addition to public databases of 17 species and 21 BINs. Fifty-eight specimens were collected in Portugal and 18 in Spain during the period of 2004 to 2018. All specimens are deposited in the IBI collection at CIBIO, Research Center in Biodiversity and Genetic Resources, and their DNA barcodes are publicly available in the Barcode of Life Data System (BOLD) online database. The distribution dataset can be freely accessed through the Global Biodiversity Information Facility (GBIF).

Project description:BackgroundDNA barcoding technologies have provided a powerful tool for the fields of ecology and systematics. Here, we present a part of the InBIO Barcoding Initiative Database: contribution to the knowledge on DNA barcodes of cuckoo wasps (Hymenoptera, Chrysididae) dataset representing 144 specimens and 103 species, covering approximately 44% of the Iberian and 21% of the European fauna. The InBIO Barcoding Initiative (IBI - DNA Barcoding Portuguese terrestrial invertebrate biodiversity) aims to fill the barcoding gap for the terrestrial invertebrate taxa. All DNA extractions are deposited in the IBI collection at CIBIO, Research Center in Biodiversity and Genetic Resources and specimens are deposited in the University of Mons collection (Belgium) and in the Natur-Museum in Lucerne (Switzerland).New informationThis dataset increases the knowledge on the DNA barcodes and distribution of 102 species of cuckoo wasps. A total of 52 species, from 11 different genera, were new additions to the Barcode of Life Data System (BOLD), with DNA barcodes for another 44 species added from under-represented taxa in BOLD. All specimens have their DNA barcodes publicly accessible through the BOLD online database. Nine cuckoo wasp species are newly recorded for Portugal. Additionally, two new species for science are described: Chrysiscrossi Rosa, sp. nov. from southern Portugal and Hedychridiumcalcarium Rosa, sp. nov. from eastern Spain. Several taxonomic changes are proposed and Hedychrumrutilans Dahlbom, 1845 is found to consist of two different taxa that can be found in sympatry, Hedychrumrutilans s. str. and Hedychrumviridaureum Tournier, 1877 stat. nov. Stilbumwestermanni Dahlbom, 1845 stat. nov. is confirmed as distinct from Stilbumcalens (Fabricius, 1781), with the latter species not confirmed as present in Iberia; barcoded Stilbum material from Australia is distinct and represents Stilbumamethystium (Fabricius, 1775) sp. resurr.; Portuguese material identified as Hedychridiumchloropygum Buysson, 1888 actually belongs to Hedychridiumcaputaureum Trautmann & Trautmann, 1919, the first confirmed record of this species from Iberia. Philoctetesparvulus (Dahlbom, 1845) is confirmed to be a synonym of Philoctetespunctulatus (Dahlbom, 1845). Chrysislusitanica Bischoff, 1910 is confirmed as a valid species. Chrysishebraeica Linsenmaier, 1959 stat. nov. is raised to species status.

Project description:Accurate identification of Arctic plant species is critical for understanding potential climate-induced changes in their diversity and distributions. To facilitate rapid identification we generated DNA barcodes for the core plastid barcode loci (rbcL and matK) for 490 vascular plant species, representing nearly half of the Canadian Arctic flora and 93% of the flora of the Canadian Arctic Archipelago. Sequence recovery was higher for rbcL than matK (93% and 81%), and rbcL was easier to recover than matK from herbarium specimens (92% and 77%). Distance-based and sequence-similarity analyses of combined rbcL + matK data discriminate 97% of genera, 56% of species, and 7% of infraspecific taxa. There is a significant negative correlation between the number of species sampled per genus and the percent species resolution per genus. We characterize barcode variation in detail in the ten largest genera sampled (Carex, Draba, Festuca, Pedicularis, Poa, Potentilla, Puccinellia, Ranunculus, Salix, and Saxifraga) in the context of their phylogenetic relationships and taxonomy. Discrimination with the core barcode loci in these genera ranges from 0% in Salix to 85% in Carex. Haplotype variation in multiple genera does not correspond to species boundaries, including Taraxacum, in which the distribution of plastid haplotypes among Arctic species is consistent with plastid variation documented in non-Arctic species. Introgression of Poa glauca plastid DNA into multiple individuals of P. hartzii is problematic for identification of these species with DNA barcodes. Of three supplementary barcode loci (psbA-trnH, psbK-psbI, atpF-atpH) collected for a subset of Poa and Puccinellia species, only atpF-atpH improved discrimination in Puccinellia, compared with rbcL and matK. Variation in matK in Vaccinium uliginosum and rbcL in Saxifraga oppositifolia corresponds to variation in other loci used to characterize the phylogeographic histories of these Arctic-alpine species.
