-> (i): aims to evaluate the response of ecosystems to biological invasions, specifically the Louisiana crayfish (Procambarus clarkii). Using a long-term approach in aquatic mesocosms, analyse the different biological compartments (phytoplankton, zooplankton, periphyton, macrophytes, macroinvertebrates) as well as the essential functionalities of ecosystems, with the aim of understanding the impacts of this species on aquatic ecosystems as a whole.

 -> (ii): aims to study the long-term impacts of invasive crayfish on food webs, using both experimental and modelling approaches. As part of a mesocosm experiment, monitoring the population dynamics of multiple biological compartments of the ecosystem, including phytoplankton, zooplankton, periphyton, macrophytes, macroinvertebrates and crayfish. These data provide information on how crayfish influence the ecological balance and stability of food webs in lentic environments. In addition, meta-analysis of the existing literature to assess the effects of invasive species on the structure and dynamics of food webs.
