Integrating physiological tolerance, biotic interactions, and dispersal ability into (meta)population models (A18)

• Subject Area: Ecology and Biodiversity of Animals and Ecosystems, Organismic Interactions
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 426547801

Phase II of A18 aims to simulate individual and population processes during degradation and recovery. First, individual and population responses will be empirically modelled, through: (i) a population growth model for diatoms; and (ii) a meta-analysis on the recovery potential of organisms based on their acute and chronic responses. Furthermore, the relative importance of tolerance and biotic interactions will be evaluated using experimental results of RESIST. Finally, the dynamics and structure of a Gammarus pulex population will be modelled, integrating tolerance and intraspecific interactions. Fourth, a metapopulation model will be developed for this species, additionally including dispersal ability.
