Titre : « What is going on down (under) there? Multidisciplinary approaches to unveil functional ecology of aquatic ecosystems ».

Résumé :

« Inland aquatic ecosystems are essential upholders of global biodiversity, as they provide a plethora of services to nature and humanity. Despite their importance, these ecosystems are increasingly exposed to anthropogenic pressures. Worryingly, our ability to survey for the taxonomic and functional diversity that groundwaters, rivers, lakes, etc. host – and therefore assure their effective protection – is far from perfect. Nonetheless, recent advances in molecular designs, such as environmental DNA (eDNA), DNA barcoding or the use of ‘omics’, are opening a new era of quick, reliable and relatively affordable biomonitoring techniques. Particularly, eDNA analysis has proved to be an ideal complementary tool for surveying a plethora of aquatic communities, detect the presence of invasive/threatened species, investigating the dietary preferences of targeted groups, and assessing the ecological status of a water body, amongst many other applications. eDNA has also served to build bridges between researchers and citizens in the form of participatory science projects both at local and global scales. In addition, the integration of eDNA data with biogeochemical approaches (e.g., derived from stable isotopes or fatty acid analysis) has recently shed new crucial light on the energy flows, organic interchanges and food web interactions shaping aquatic biota. Ultimately, such novel approaches have the potential to guide tailored conservation strategies for more resilient aquatic ecosystems under the current changing climate. In this seminar Dr Mattia Saccò will share his experience on the application of functionally-based approaches to unravel the ecological dynamics of several aquatic ecosystems, spanning groundwaters to hypersaline lakes ».
