空间异质性是资源专家进化的关键驱动力，并已被证明既促进又限制适应速度。然而，这些空间异质性的进化后果的直接经验支持来自简化的实验室环境。在这里，我们解决如何空间结构，通过其对资源异质性的影响，改变多样化和适应性进化的土壤bacteriumPseudomonasfluorescensin生态相关的背景下：土壤堆肥。我们的数据表明，环境异质性既可以促进表型多样化，也可以加速适应。这些结果表明，环境干扰，可以减少空间异质性，可能会限制微生物种群的多样性和适应性。
Spatial heterogeneity is a key driver for the evolution of resource specialists and has been shown to both promote and constrain the rate of adaptation. However, direct empirical support for these evolutionary consequences of spatial heterogeneity comes from simplified laboratory environments. Here we address how spatial structure, through its effect on resource heterogeneity, alters diversification and adaptive evolution of the soil bacteriumPseudomonas fluorescensin an ecologically relevant context: soil-based compost. Our data show that environmental heterogeneity can both promote phenotypic diversification and accelerate adaptation. These results suggest that environmental disturbance, which can decrease spatial heterogeneity, may limit diversification and adaptation of microbial populations.
