Climate change influence on biodiversity, goods and services of Mediterranean lagoons
Objective(s)Scientific assessment of Climate Change effects on lagoons ecosystem in comparison with man-induced changes
The CLIMBIOMEDNET research project has investigated, using theory, observations and predictions, the relationships between biodiversity, ecosystem properties and temperature and salinity changes, which are going to be the immediate effects of climate change on Mediterranean lagoons. To this aim, (i) we developed a theoretical background highlighting paradoxes (low biodiversity but high productivity) and common trends (dominance of generalist species) for these particular ecological systems, (ii) we built the largest database on Mediterranean and Black Sea lagoons available on the web (Climbiomednet Web Portal: www.circlemednet.unisalento.it) gathering information on 635 lagoons with biological (species lists) and physico-chemical (salinity, temperature) parameters, and (iii) we collected projections of climate change for each lagoon and its watershed regarding land use, temperature, precipitation and salinity.
We show that the overall lagoon surface area in the Mediterranean and Black Sea basins is close to 10,000 km2 with few large lagoons and many small ones (314 out of 635 have a surface area lower than 1 km2). Our results on biodiversity point out that most of species are rare with half of species detected in a single lagoon. At the regional scale (Italy) our analyses suggest a decoupling between the strength of conservation funding and the gradient of ecological status with respect to macro invertebrates species richness. Finally, following the A2 IPCC scenario, sea surface temperature (SST) in front of coastal lagoons is expected to increase by 0.11°C and 1.21°C by the middle and the end of the century, respectively, with a maximum temperature increase of 2.54°C by the end of the century in the Adriatic Sea and more particularly for lagoons along the coast of Croatia.
As a perspective, the CLIMBIOMEDNET Transitional Waters Platform will contribute to the large research infrastructure project LifeWatch to maximize the accessibility of data, their integration and use, thus substantially increasing the impact of the CLIM.BIO.MED.NET project towards Mediterranean scientific and stakeholder communities interested in lagoon biodiversity. This integration will contribute to tackle the challenge of (i) anticipating climate change effects on Mediterranean lagoon biodiversity and functioning and (ii) identifying areas of conservation priorities.
Added value to theMediterranean scientific community
The Mediterranean scientific community will gain from the CLIMBIOMEDNET project at least in four ways. First, the database, which will be available for scientists, will allow to tackle many issues dealing with lagoon biodiversity and climate change. Beyond the scientific papers written by the project partners we believe that many future research studies will benefit from the database and the credit will be given to the CLIMBIOMEDNET project. Second, the data gathered during the project will help the Mediterranean scientific community working on coastal lagoons to propose new, innovative and ambitious projects at regional, national and international levels. Indeed the existence of such an database and such a web tool will bring convincing arguments to any initiatives. Third, the original results we have provided (the heterogeneity of biodiversity distribution and of climate change impacts), shed light on the need to consider a local scale when assessing the potential threats on coastal lagoons and the map we have produced will contribute to focus on critical areas. Fourth, protected areas are established worldwide to counteract human impacts on ecosystems. However the strategic choice for the new protected areas is highly controversial and even more challenging when spatial information in lacking and when climate change interplays. Our project, which overcomes these two limitations, may help conservationists to propose appropriate designs of protected areas dedicated to coastal lagoons and their watersheds.
