Higher trophic status leads to more diverse and divergent microeukaryote communities over time in urban lakes from the Greater Paris (France) Open
Effects of trophic status on lake microeukaryote community dynamics remain underexplored. Spanning oligotrophic to hypereutrophic conditions, peri-urban lakes located in the Greater Paris region (France) offer unique opportunities to compa…
