摘要
A long-standing question in community 生態學 is what determines the identity of 物種 that coexist across local communities or metacommunity assembly. To shed light upon this question, we used a 網絡 approach to analyse the drivers of 物種 co-occurrence patterns. In particular, we focus on the potential roles of body size and 營養級 status as determinants of metacommunity cohesion because of their link to resource use and dispersal ability. Small-sized individuals at low-營養級 levels, and with limited dispersal potential, are expected to form highly linked subgroups, whereas large-size individuals at higher 營養級 positions, and with good dispersal potential, will foster the spatial coupling of subgroups and the cohesion of the whole metacommunity. By using modularity analysis, we identified six modules of
