Nutrient subsidies to belowground microbes impact aboveground food web interactions.

abstract：:Ecologists are faced with the challenge of how to scale up from the activities of individual plants and animals to the macroscopic dynamics of populations and communities. It is especially difficult to do this in communities of plants where the fate of individuals depends on their immediate neighbors rather than an av...
