Spatial Scaling of Microbial Diversity across Various Functional and Phylogenetic Taxa

摘要: Understanding the spatial patterns of organisms and underlying mechanisms shaping biotic communities is a central goal in community ecology. One most well documented plant animal positive-power law relationship between species (or taxa) richness area. Such taxa-area relationships (TARs) are one principal generalizations ecology, fundamental to our understanding distribution global biodiversity. However, TARs remain elusive controversial microbial communities, especially soil habitats, due inadequate sampling methodologies. Here, we describe TARs, at whole-community level, across various functional phylogenetic groups forest using comprehensive gene array (FGA) with > 24,000 probes. Our analysis indicated that exhibited relatively flat (slope z = 0.0624), but values varied considerably different (z 0.0475-0.0959), which several times lower than those commonly observed higher plants animals. These results suggest turnover space microorganisms may be, general,
