Resistance, resilience and functional recovery of a rainforest ecosystem
DFG-funded Research Unit REASSEMBLY (FOR 5207) will start in November 2021 (see News)
REASSEMBLY aims at understanding network dynamics to uncover rules of network dis- and reassembly in a highly diverse tropical lowland rainforest ecosystem. We will study the dynamics of natural forest recovery from agriculture along a chronosequence and the contribution of re-assembled networks to the resilience of ecosystem processes against perturbation. We will compare the trajectories of predator–prey, plant–pollinator, and plant–seed disperser networks, as well as decomposition networks between mammals, dung beetles and seeds, and between dead wood, ants, termites, and beetles. Subprojects thus examine networks of all major ecosystem processes mediated by interspecific interactions: predation, pollination, primary and secondary seed dispersal, herbivory, decomposition, and tree seedling recruitment. Networks and ecosystem processes will be studied along a large-scale chronosequence of forest recovery (62 plots representing different stages of succession) and in a small-scale perturbation–recruitment experiment.
Our MISSION: Although REASSEMBLY is a basic scientific research unit, our aim is to ensure that the knowledge gained can be applied and contribute to optimizing the restoration of tropical forests. This research project, funded by the German Research Foundation (DFG), will not only be conducted within a forest in Ecuador, but on an equal footing with the Ecuadorian scientific community in different institutions and with an Ecuadorian conservation organization (Fundación Jocotoco). Our goal is to strengthen ecological science and the next generation of scientists in both countries, as well as nature conservation efforts that meet the interests of local communities. To achieve these goals, transparent and accessible data and results are essential.
