IMOST: a database for non-marine ostracods in the Iberian Peninsula, the Balearic Islands and Macaronesia

Ostracods are common microcrustaceans in inland waters, widely used as (palaeo-) environmental indicators. Information on their species distribution worldwide is extremely fragmentary, and usually biased towards some regions, hampering attaining a general view of biogeography. The Iberian Peninsula, the Balearic Islands Macaronesia considered biodiversity hotspots part Mediterranean Region, whose non-marine ostracod fauna was reviewed 1990s accounting for 88 species. Most these data were included NODE database (Non-marine Ostracod Distribution Europe). Here, we present IMOST (Ibero-Balearic Macaronesian OSTracod database), Peninsula Islands, incorporating plus many new records from recently published studies unpublished observations. Our stores separated standardised spreadsheets, one each source. Moreover, also offers updated, accurate coordinates cited occurrence taxonomic identification. According to compiled IMOST, updated list ostracods studied region 118 Nevertheless, expect that actual number regions should be higher, considering other countries with smaller areas but more extensive surveys (e.g. 152 Italy). instrumental our understanding biogeographic patterns organisms this hotspot, well analysing species-environment relationships context global changes.
