Method steps

1. The present database (IMOST) compiled georeferenced occurrences of non-marine ostracods in the study area from 1887 to 2022. These data originate both from published records and from unpublished observations. Initially, we checked and added the occurrences previously included in NODE (Horne et al., 1998) for the study area, and then further added published and unpublished records not included in NODE. Most ostracod records in the database originated from field samples fixed in the field (e.g., with ethanol), and transported to the laboratory for inspection. Ostracod individuals are usually sorted out from these samples under a binocular microscope in the laboratory and identified using standard references (e.g. Meisch, 2000). Samples of living ostracods can be collected by pulling a plankton or hand net close to the sediment or through the vegetation . Additionally, some studies also record empty carapaces or unarticulated valves (i.e. exuviae or dead animal remains) from sediment. We include all these records in a homogeneous format, considering the ostracod community of each sample, with all the species found in it, although we later split each sample into its corresponding species records to allow easy database sharing in a standard structure for biodiversity data repositories, as in NODE or GBIF
