Ostracods (Crustacea, Ostracoda) from Doñana (SW Spain): an updated checklist, including new records, of Recent and Quaternary non-marine, marine and brackish species in the area
Here we provide an updated list of ostracod taxa (Crustacea, Ostracoda) identified from freshwater, brackish and marine (infralittoral) environments in the 'Doñana Natural Area' and alongside its adjacent shores. This list, based on both published and new records, encompasses a total of 101 species spanning a stratigraphic sequence from the Lower Pliocene to the present. Sixty-five marine species have been found to occur in the area (11 of which also thrive in brackish waters); of which just over 50% (34 spp.) are present both in Recent samples collected in the infralittoral zone, and as fossils/subfossils found in sediment cores. Nineteen other marine species have been found solely in the infralittoral zone whereas other twelve species occurred exclusively as fossils or subfossils in sediment cores. Conversely, the total number of non-marine species recorded amounts to thirty-seven, eight of which are new records for ‘Doñana Natural Area’. All the non-marine species recorded have been found as living organisms in Recent samples although seven of them have been found as subfossils in sediment cores as well. In agreement with the diversity of aquatic habitats in the area and the sampling effort carried out over more than six decades, the non-marine ostracofauna of Doñana constitutes a significant portion (~33%) of the overall known species richness across the Iberian Peninsula.
