Linking macrophyte community structure with food chain length: A case study in the largest freshwater lake in China and ecological restoration implications

Food chain length is a significant ecosystem index and it greatly affects ecosystem processes and their outcomes. In recent decades, determinants or indicators of FCL have been investigated in different ecological contexts, but few studies analyzed the relationships between macrophyte community stru...
