Increased positive tree species mixture effects on the abundance and richness of Collembola with stand development in natural boreal forests

We investigated the effects of tree species mixtures on Collembola abundance, diversity, and community structure by sampling both pure and mixed jack pine (Pinus banksiana Lamb.) and trembling aspen (Populus tremuloides Michx.) of 15-year-old and 41-year-old stands in natural boreal forest.
