The importance of hydrology, salinity and colonization for the ecology of temporal wetlands in the Camargue.


In this PhD study we assess spatio-temporal patterns in the invertebrate communities of pristine temporary wetlands in the Camargue (southern France). We especially focus on the impact of hydrology and salinity on the life history of selected species and the invertebrate community structure. We combine field surveys and experiments in the field (testing of impact of hydrology x salinity regimes) and in the laboratory (testing of tolerance). Our information will be used to predict any changes in community structure and richness according to various scenarios of global change and intensive water management. In a second part we evaluate the early colonisation of newly created wetlands varying in hydroperiod and surface. The study area is the nature reserve of 'Tour du Valat' where there are many pristine temporary wetlands along a hydroperiod and salinity gradient. Temporary Mediterranean wetlands are listed as priority habitat in the habitat directive, nevertheless their conservation value is often neglected. Our study will contribute to a better knowledge of the invertebrate communities in these wetlands, but will also provide useful information to develop conservation and management strategies for these unique habitats. This project is funded by IWT-Vlaanderen and is in cooperation with the research centre of 'Tour du Valat'
