REASSEMBLY

Reassembly of species interaction networks

Resistance, resilience and functional recovery of a rainforest ecosystem

​DFG-funded Research Unit REASSEMBLY (FOR 5207) Posts @bsky
1st funding phase 2021-2025, 2nd phase 2026-2029

REASSEMBLY aims at understanding network dynamics to uncover rules of network dis- and reassembly in a highly diverse tropical lowland rainforest ecosystem. We 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 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 are 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 Research Unit is funded by the Deutsche Forschungsgemeinschaft (DFG).

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 Deutsche Forschungsgemeinschaft (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.

  • Animal seed dispersers recover later than plants, but forest connectivity helps
    Anna Landim and collaborators found that animal communities recover more slowly than plant communities, mainly because remnant trees help maintain plant functional diversity and attract animals early in the regeneration process. Their study estimated that animal functional diversity takes about 40 years to reach levels comparable to those of old-growth forests. Moreover, landscape connectivity plays …
