Using DNA barcodes to detect non-indigenous species: the case of the Asian copepod Mesocyclops pehpeiensis Hu, 1943 (Cyclopidae) in two regions of the world
To date, little attention has been paid to analyses of copepods as exotic species. The genusMesocyclops, a freshwater cyclopoid, has a worldwide distribution, but individual species within the genus have a quite restricted geographical range.Mesocyclops pehpeiensisHu, 1943 is a Central-East Asian species, rarely found outside of this area, and when it appears should be considered as non-native. Based on morphology and DNA barcode analyses, using the COI gene, we confirmed records ofM. pehpeiensisin two ponds in Mexico and in a rice paddy near Valencia, Spain. The morphology of this species, based on morphometric analyses, was found to be variable, but DNA barcoding confirmed the same identi…
THE FRESHWATER CLADOCERA (ORDERS CTENOPODA AND ANOMOPODA) OF MEXICO, WITH COMMENTS ON SELECTED TAXA
AbstractKnowledge of the composition and distribution of the freshwater Cladocera in Mexico is still limited. All the available literature was reviewed and added to our own new records in different states of Mexico to present here a revised and updated list of the 110 species of the orders Ctenopoda and Anomopoda recorded for the country, with separate state records. Ecological, biogeographical, and taxonomic comments are made for selected taxa of the commonest neotropical groups: Sididae, Daphniidae, Bosminidae, Macrothricidae, and Chydoridae. La connaissance de la composition et de la repartition des Cladoceres d'eau douce du Mexique est encore tres limitee. Toute la litterature disponibl…
