High evolutionary rates in mixed community-assembly scenarios decrease invasion success, consistent with community monopolization, while immigration yields more species-rich communities with diverse specialist characters.
- Why it matters: Community assembly studies often ignore how generalism changes with the biotic environment, leaving uncertainty about how coevolution and dispersal history jointly shape specialist–generalist community structure.
- What they did: They model assembly along a continuum from pure coevolution to pure dispersal, comparing evolutionary assembly versus repeated immigration, and track richness, generalism, and invasion success under varying evolution rates.
- The result: Coevolution can produce diversification and asymmetric generalist–specialist configurations, with alternative evolutionary endpoints including many specialists or fewer generalists that may be locally uninvasible; immigration increases species richness and specialist diversity, while higher evolution reduces invasion success in mixed assemblies.
