Regional-Scale Environmental Resistance To Non-Native Ant Invasion, Robert Warren
Regional-Scale Environmental Resistance To Non-Native Ant Invasion, Robert Warren

A successful invasion of novel habitat requires that non-native organisms overcome native abiotic and biotic resistance. Non-native species can overcome abiotic resistance if they arrive with traits well-suited for the invaded habitat or if they can rapidly acclimate or adapt. Non-native species may co-exist with native species if they require novel, underused resources or if they can out-compete similar native species. We investigated abiotic and biotic resistance to the progression of a Brachyponera chinensis invasion in the southeastern U.S. relative to the dominant native woodland ant (Aphaenogaster). We used observational data from long-term plots along the elevation gradient …
