产生生物多样性的进化过程和维持生物多样性的生态机制本身似乎是不同的。对生物多样性的传统解释，如生态位分化、依赖密度的捕食压力或栖息地异质性，似乎令人满意地解释了高等动植物等大型生物群落的多样性。长期以来，在看似一致的环境中，微生物之间往往存在着高度的多样性，这一著名的“浮游生物悖论”一直令人费解。细菌群落的生物多样性已被证明有时比已知的大型微生物系统的多样性高出几个数量级。基于具有多重循环优势结构的空间显式博弈论模型，我们认为微生物群落内的抗生素相互作用可能在维持多样性方面非常有效。
Evolutionary processes generating biodiversity and ecological mechanisms maintaining biodiversity seem to be diverse themselves. Conventional explanations of biodiversity such as niche differentiation, density-dependent predation pressure, or habitat heterogeneity seem satisfactory to explain diversity in communities of macrobial organisms such as higher plants and animals. For a long time the often high diversity among microscopic organisms in seemingly uniform environments, the famous "paradox of the plankton," has been difficult to understand. The biodiversity in bacterial communities has been shown to be sometimes orders of magnitudes higher than the diversity of known macrobial systems. Based on a spatially explicit game theoretical model with multiply cyclic dominance structures, we suggest that antibiotic interactions within microbial communities may be very effective in maintaining diversity.
