Ecological drivers of soil microbial diversity and soil biological networks in the Southern Hemisphere.

abstract：:Habitat fragmentation produces small, spatially isolated populations that promote inbreeding. Remnant populations often contain inbred and outbred individuals, but it is unclear how inbreeding relative to outbreeding affects the expression of functional traits and biotic interactions such as herbivory. We measured a s...
