Air-dispersed microorganisms on different freshwater colonization habitats

In this study, we attempted to mimic aeolian ecosystems where any inputs to water bodies are airborne, to examine how filters posed by water characteristics, such as the trophic state (i.e. nutrient concentrations) and salinity, can influence the establishment and growth of airborne microcolonizers of a common air source. Specifically, we aimed to investigate the colonization, establishment, and growth potential of air-dispersed microorganisms in open freshwater experimental containers, containing organism-free sterilized water from different water bodies, representing different trophic gradients.

本研究旨在模拟风成生态系统（aeolian ecosystems）——该系统中所有输入水体的物质均为气源性输入——以探究水体特征所介导的筛选效应，例如营养状态（trophic state，即营养盐浓度）与盐度（salinity），如何影响常见空气气源中气源性微定殖微生物（airborne microcolonizers）的定殖与生长。具体而言，本研究旨在探究空气传播微生物在开放式淡水实验容器中的定殖、种群建立与生长潜力；该实验容器内装载有取自不同水体的无菌灭菌水，用以模拟不同营养梯度环境。
