许多生物生活在营养或空间有限的栖息地,对这些资源的竞争无处不在。虽然与人口殖民空间方式有关的空间因素影响其在空间竞争中的成功,但这些因素是什么以及它们在多大程度上影响结果仍未得到充分探讨。在这里,我们应用一个模拟的竞争模型来探索影响空间竞争结果的空间因素。通过量化空间因素,我们表明以更分散的方式殖民空间有助于微生物竞争的成功。我们还发现,在殖民过程中,来自更分散的方式的竞争优势可以弥补由于较低的增长率或较低的初始丰度而产生的劣势。这些发现阐明了空间殖民方式在维持生态系统内生物多样性方面的作用,并提供了新的见解,对于理解对空间的竞争如何推动进化创新至关重要。
Many organisms live in habitats with limited nutrients or space, competition for these resources is ubiquitous. Although spatial factors related to the population’s manner of colonizing space influences its success in spatial competition, what these factors are and to what extent they influence the outcome remains underexplored. Here, we applied a simulated competitive model to explore the spatial factors affecting outcomes of competition for space. By quantifying spatial factors, we show that colonizing space in a more dispersed manner contributes to microbial competitive success. We also find that the competitive edge deriving from a more dispersed manner in colonization can compensate for the disadvantage arising from either a lower growth rate or lower initial abundance. These findings shed light on the role of space colonization manners on maintaining biodiversity within ecosystems and provide novel insights critical for understanding how competition for space drives evolutionary innovation.
