In this study, we examined the effects of physicochemical variability on the microbial communities of vernal pools. Denaturing gradient gel electrophoresis revealed temporal changes to be more pronounced than spatial changes in eukaryotic and bacterial communities. Sequencing revealed high degrees of richness in decomposers, which supports the notion that vernal pools are heterotrophic habitats.
在本研究中,我们考察了物理化学变异性对季节性池塘微生物群落的影响。变性梯度凝胶电泳显示,真核生物和细菌群落的时间变化比空间变化更为显著。测序结果表明分解者的丰富度很高,这支持了季节性池塘是异养栖息地的观点。
