André M. de Roos (University of Amsterdam): Dynamics of within-population structure stabilise complex ecological communities
October 27 @ 9:00 - 10:00 PDT
During this week the time difference between America and Europe is one hour less, than usual. The seminar will begin at 9 am Pacific, as always, but now it will correspond to 4 pm in London and 5 pm in Paris.
Dynamic models of ecological communities that neglect within-population structure predict that stability depends on substantial self-limitation of species. Using a stage-structured food web model I show that differences between juveniles and adults result in diverse ecological communities that are stable or exhibit limited-amplitude fluctuations, despite that only a single basal species is self-regulated. Eigenvalue analysis reveals that community stability results from dynamic changes in within-population stage-structure that override destabilising effects induced by the species interaction network.
