The abundance of individuals in microbial species is so large that dispersal is rarely (if ever) restricted by geographical barriers. This "ubiquitous" dispersal requires an alternative view of the scale and dynamics of biodiversity at the microbial level, wherein global species number is relatively low and local species richness is always sufficient to drive ecosystem functions.
微生物物种中的个体数量极为庞大，以至于扩散很少（如果有的话）受到地理障碍的限制。这种“无处不在”的扩散需要从微生物层面的生物多样性规模和动态的另一个角度来看待，即全球物种数量相对较少，而局部物种丰富度总是足以驱动生态系统功能。
