Abstract
One of the most significant threats to biodiversity is alien species invasion, and consequently understanding and
predicting biological invasions has become an important issue in ecology. While numerous studies have explored
the effect of community diversity and structure on invasion success, a systematic comparative analysis on system
robustness to invasion between antagonistic and mutualistic networks from a metacommunity perspective is still
lacking. Here we seek to address this gap using patch-dynamic models, which integrate local communities into
the landscape metacommunity. We find that both mutualistic and antagonistic metacommunities displayed
qualitatively similar responses to species invasion, except for animal invasion in antagonistic networks. Specifically, increasing network size and connectance generally promoted metacommunity persistence, while
nestedness (negative) and modularity (positive) had contrasting effects on metacommunity robustness to invasion. However, these structural effects were strongly dependent on the generalization levels of both invader and
the resident species it displaces. Overall, this study provides new and more general insights into how alien
species are well integrated into native networks and how they affect metacommunity persistence.
