Abstract: Natural habitats consist of a large variety and variability of environmental factors. Reproduction in laboratory cultures is thus a highly effective way to pinpoint and quantify the impact of a specific environmental factor on a species which is hardly possible in natural environments.The most common ostracod species in European marginal marine environments is Cyprideis torosa (Jones, 1850). It is a morphologically variable species but laboratory reproduction experiments of C. torosa are scarce and thus reducing an undisputed use of its morphological variability as a paleo-environmental proxy.Although it is usually intended to use ostracod valves as paleo-thermometer, the nature of the impact of temperature on ostracods and on their morphology remains questionable. We aim to test whether temperature plays a significant role influencing the morphological characteristics of C. torosa in different salinities. In addition, laboratory cultures are a great opportunity to better understand the life cycle of ostracods, their reproduction times and juvenile numbers.We collected samples from Marano Lagoon (Italy) at salinity levels of 7.2, 17.2 and 29.6 psu. For our experimental setup, we transferred boiled (= sterile) sediment (
