Plant traits mediate consumer and nutrient control on plant community productivity and diversity.

abstract：:Despite important advances in the ecology of river food webs, the strength and nature of the connection between the meio- and macrofaunal components of the web are still debated. Some unresolved issues are the effects of the inclusion of meiofaunal links and their temporal variations on the overall river food web prop...
