有限生态位的种内竞争被认为是适应性辐射的驱动力，但种间竞争的作用的结果是混合的。在这里，我们报告了在四种竞争细菌物种的不同数量和组合存在的情况下，模式细菌荧光假单胞菌的适应性多样化。竞争群落多样性的增加增加了焦点种的形态多样性，这是由于阻碍了单一形态型的优势。具体来说，这种模式是由更多样化的社区更有可能包含占据相同的生态位，否则竞争性上级形态型的关键物种，从而防止竞争性排斥内的焦点物种。我们的研究结果表明，同域适应性辐射是由存在或不存在的利基特定的竞争对手。
Intraspecific competition for limited niches has been recognized as a driving force for adaptive radiation, but results for the role of interspecific competition have been mixed. Here, we report the adaptive diversification of the model bacteria Pseudomonas fluorescens in the presence of different numbers and combinations of four competing bacterial species. Increasing the diversity of competitive community increased the morphological diversity of focal species, which is caused by impeding the domination of a single morphotype. Specifically, this pattern was driven by more diverse communities being more likely to contain key species that occupy the same niche as otherwise competitively superior morphotype, and thus preventing competitive exclusion within the focal species. Our results suggest that sympatric adaptive radiation is driven by the presence or absence of niche-specific competitors.
