Improving the conservation of Mediterranean Chondrichthyans : the ELASMOMED DNA barcode reference library
2017
Cartilaginous fish are particularly vulnerable to anthropogenic stressors and environmental change because of their K-selected reproductive strategy. Accurate data from scientific surveys and landings are essential to assess conservation status and to develop robust protection and management plans. Currently available data are often incomplete or incorrect as a result of inaccurate species identifications, due to a high level of morphological stasis, especially among closely related taxa. Moreover, several diagnostic characters clearly visible in adult specimens are less evident in juveniles. Here we present results generated by the ELASMOMED Consortium, a regional network aiming to sample …
An integrative approach challenges species hypotheses and provides hints for evolutionary history of two Mediterranean freshwater palaemonid shrimps …
2021
25 pages; International audience; The Mediterranean Region is a biodiversity/endemism hotspot whose freshwater fauna remains largely unexplored. Our integrative study challenges the taxonomic status of two freshwater palaemonid shrimps, Palaemon antennarius and Palaemon minos. Three molecular operational taxonomic units (MOTUs) were defined based on 352 cytochrome oxidase subunit I (COI) sequences and 88 haplotypes. Two belonged to P. antennarius: one inhabiting the Apennine Peninsula and Sicily, and the other from the Balkan Peninsula. Palaemon minos was the third MOTU, found on Crete. The Balkan MOTU of P. antennarius was genetically closer to P. minos than to the other conspecific MOTU. …
A molecular-based identification resource for the arthropods of Finland
2022
Publisher Copyright: © 2021 The Authors. Molecular Ecology Resources published by John Wiley & Sons Ltd. To associate specimens identified by molecular characters to other biological knowledge, we need reference sequences annotated by Linnaean taxonomy. In this study, we (1) report the creation of a comprehensive reference library of DNA barcodes for the arthropods of an entire country (Finland), (2) publish this library, and (3) deliver a new identification tool for insects and spiders, as based on this resource. The reference library contains mtDNA COI barcodes for 11,275 (43%) of 26,437 arthropod species known from Finland, including 10,811 (45%) of 23,956 insect species. To quantify the…

DNA barcoding for species assignment: the case of Mediterranean marine fishes
2014
Background: DNA barcoding enhances the prospects for species-level identifications globally using a standardized and authenticated DNA-based approach. Reference libraries comprising validated DNA barcodes (COI) constitute robust datasets for testing query sequences, providing considerable utility to identify marine fish and other organisms. Here we test the feasibility of using DNA barcoding to assign species to tissue samples from fish collected in the central Mediterranean Sea, a major contributor to the European marine ichthyofaunal diversity. Methodology/Principal Findings: A dataset of 1278 DNA barcodes, representing 218 marine fish species, was used to test the utility of DNA barcodes…
<strong>Identification of the nymphal stages of two European seed bugs, <em>L. equestris</em> and <em>L. simulans</em> …
2013
The genus Lygaeus Fabricius, 1794 includes more than fifty species, mainly distributed in the Old World regions, with 17 species known from the Palearctic (Pericart 2001; Wachmann et al. 2007), and only two from Central Europe, i.e., L . equestris (Linnaeus, 1758) and L . simulans Deckert, 1985 (Pericart 2001).

Aplicación de técnicas morfológicas y moleculares en la identificación de la megalopa de decápodos braquiuros de la península ibérica
2015
Entre los crustáceos decápodos, el Infraorden Brachyura Linnaeus, 1758 es el grupo más diverso y de mayor éxito evolutivo, con aproximadamente 7.000 especies pertenecientes a 98 familias (Tsang et al. 2014). Los braquiuros, comúnmente llamados cangrejos, han conquistado casi todos los hábitats y numerosos nichos ecológicos (De Grave et al. 2009; Ahyong et al. 2011). La mayoría de las especies son marinas, aunque también existen especies de agua dulce o incluso especies terrestres. El desarrollo larvario de los braquiuros suele constar de dos fases de vida libre y planctónicas (con las escasas excepciones de aquellos con desarrollo directo, principalmente de agua dulce): zoea (con varios est…
