Résumé : Mangrove forests facilitate the discovery of mechanisms beyond forests dynamics hard to address in other systems. Located between land and sea, pronounced inundation gradients provide a unique natural lab for studying the effects of negative and positive interactions among plants along gradients of multiple stress factors. On top the access to the shallow root system supports the application of non-destructive techniques for measuring tree networks via natural root grafts and the analysis of their implications for stand level dynamics. Based on case studies from Brazil and Mexico, as well as simulation experiments with agent-based models developed in our working group, I will demonstrate the importance of competition, facilitation and networking among mangrove trees for stand dynamics in heterogeneous environments. By discussing the status quo and challenges of mangrove forest ecology, I will outline a perspective towards an agent-based forest ecology.
