Branching habit and the allocation of reproductive resources in conifers.

abstract：BACKGROUND:The study of soil biota in the context of exotic plant invasions has led to an explosion in our understanding of the ecological roles of many different groups of microbes that function in roots or at the root-soil interface. Part of this progress has been the emergence of two biogeographic patterns involving...
