Crangon crangon estuarine populations were analyzed in the European coast line near the south and northern edges of its latitudinal range. This study comprises a population dynamics and productivity examination on Minho Estuary (NW of the Iberia Peninsula) and on Valosen Estuary (N coast of Norway). The populations were examined on the in uence of abiotic factors, foci in temperature, salinity, and estuarine characteristics. A comprehensive comparison among both populations was performed, including latitudinal trends, species intrinsic processes of adaptation and their responses to ecosystem changes in short time scales. This study, focused on the processes underlying adaptations to less favorable locations of abundant species, aims to contribute to a better understanding of estuarine productivity and the ecological role for this species. In fact, the knowledge of a speci c estuary functioning, its ecological role, populations sustained and physical characteristics, can provide reliable data for management polices targeting ongoing and future impacts from anthropogenic pressure, such as, the global climatic changes.
