Efficiency of crustacean zooplankton in transferring allochthonous carbon in a boreal lake.

abstract：:After much debate, there is an emerging consensus that the composition of many ecological communities is determined both by species traits, as proposed by niche theory, as well as by chance events. A critical question for ecology is, therefore, which attributes of species predict the dominance of deterministic or stoc...
