Abstract

For centuries, biologists have studied patterns of plant and animal diversity at continental scales. Until recently, similar studies were impossible for microorganisms, arguably the most diverse and abundant group of organisms on Earth. Here, we present a conti- nental-scale description of soil bacterial communities and the environmental factors influencing their biodiversity. We collected 98 soil samples from across North and South America and used a ribosomal DNA-fingerprinting method to compare bacterial com- munity composition and diversity quantitatively across sites. Bac- terial diversity was unrelated to site temperature, latitude, and other variables that typically predict plant and animal diversity, and community composition was largely independent of geo- graphic distance. The diversity and richness of soil bacterial com- munities differed by ecosystem type, and these differences could largely be explained by soilpH(r2?0.70 and r2?0.58, respectively; P
