Ostracoda are microcrustaceans whose soft parts are enclosed in a bivalve carapace composed of low-Mg calcite. Their small dimensions (0.4 to 2.0 mm on average) and hard parts coupled with a long evolutionary history (from Ordovician to Present) and adaptation to all kinds of aquatic habitat make them a successful taxonomic group for paleontological analyses (Rodriguez-Lazaro and Ruiz-Muñoz, 2012). Ostracoda are mainly benthonic and are very strictly linked to their environment. They are particularly sensitive to salinity, depth, temperature, and bottom substrate, as well as hydrochemistry, nutrient content, and pollution. In addition, their carapace is a source of biogenic carbonate, suitable for geochemical studies (Ito et al., 2003). For all these reasons, Ostracoda represent an excellent proxy for the studies of paleoenvironmental changes during the Phanerozoic (Boomer et al., 2003) aswell as for climate reconstructions during Quaternary as widely demonstrated by the recent volume edited by Horne et al. (2012). The present volume, “Ostracoda as proxies for palaeoenvironmental changes — Selected papers from 17th ISO” assembles selected research on paleoenvironments based on Ostracoda that was presented at the 17th International Symposium on Ostracoda, held in Rome (Italy) from the 22nd to the 26th of July, 2013. Prior to this volume, three special issues of Palaeogeography, Palaeoclimatology, Palaeoecology (Holmes and Horne, 1999; Ikeya et al., 2005; Mischke and Holmes, 2008) have stemmed from the International Symposium on Ostracoda (ISO), one of the largest international micropaleontological conferences with a focus on a single microfossil group. The ISO meetings bring together ostracod researchers from all around the world every 4 years to discuss and exchange classic and novelmethods and applications in the study of Ostracoda in a professional but collegial atmosphere. Presentations at these symposia have often been the prelude to notable and significant publications that have advanced our knowledge on the biology, taxonomy, evolution, and ecology of this group of micro-crustaceans and enhanced their application to the earth sciences. The principle of publishing these works in a special issue of a prestigious international journal such as Palaeogeography, Palaeoclimatology, Palaeoecology is intended to bring the latest developments in ostracod research not just to ostracodologists, but also to the wider earth science scientific community.

Abstract
Ostracoda are microcrustaceans whose soft parts are enclosed in a bivalve carapace composed of low-Mg calcite. Their small dimensions (0.4 to 2.0 mm on average) and hard parts coupled with a long evolutionary history (from Ordovician to Present) and adaptation to all kinds of aquatic habitat make them a successful taxonomic group for paleontological analyses (Rodriguez-Lazaro and Ruiz-Muñoz, 2012). Ostracoda are mainly benthonic and are very strictly linked to their environment. They are particularly sensitive to salinity, depth, temperature, and bottom substrate, as well as hydrochemistry, nutrient content, and pollution. In addition, their carapace is a source of biogenic carbonate, suitable for geochemical studies (Ito et al., 2003). For all these reasons, Ostracoda represent an excellent proxy for the studies of paleoenvironmental changes during the Phanerozoic (Boomer et al., 2003) aswell as for climate reconstructions during Quaternary as widely demonstrated by the recent volume edited by Horne et al. (2012). The present volume, “Ostracoda as proxies for palaeoenvironmental changes — Selected papers from 17th ISO” assembles selected research on paleoenvironments based on Ostracoda that was presented at the 17th International Symposium on Ostracoda, held in Rome (Italy) from the 22nd to the 26th of July, 2013. Prior to this volume, three special issues of Palaeogeography, Palaeoclimatology, Palaeoecology (Holmes and Horne, 1999; Ikeya et al., 2005; Mischke and Holmes, 2008) have stemmed from the International Symposium on Ostracoda (ISO), one of the largest international micropaleontological conferences with a focus on a single microfossil group. The ISO meetings bring together ostracod researchers from all around the world every 4 years to discuss and exchange classic and novelmethods and applications in the study of Ostracoda in a professional but collegial atmosphere. Presentations at these symposia have often been the prelude to notable and significant publications that have advanced our knowledge on the biology, taxonomy, evolution, and ecology of this group of micro-crustaceans and enhanced their application to the earth sciences.
