In his seminal work in the 1970s Robert May suggested that there was an upperlimit to the number of species that could be sustained in stable equilibrium byan ecosystem. This deduction was at odds with both intuition and the observedcomplexity of many natural ecosystems. The so-called stability-diversity debateensued, and the discussion about the factors making an ecosystem stable orunstable continues to this day. We show in this work that dispersal can be adestabilising influence. To do this, we combine ideas from Alan Turing's workon pattern formation with May's random-matrix approach. We demonstrate how astable equilibrium in a complex ecosystem with two trophic levels can becomeunstable with the introduction of dispersal in space. Conversely, we show thatTuring instabilities can occur more easily in complex ecosystems with manyspecies than in the case of only a few species. Our work shows that adding moredetails to the model of May gives rise to more ways in which an equilibrium canbecome unstable. Making May's simple model more realistic is therefore unlikelyto remove the upper bound on complexity.
