Freshwater salinization modulates stream bacterial diversity via environmental filtering

Freshwater salinization is a pervasive water quality issue but it's direct effects on bacterial community membership and assembly mechanisms were unknown. Our objectives were to use controlled laboratory experiments to determine the effects of a salinity gradient within the freshwater range on bacterial community structure and diversity and assess whether individual chloride salts characteristic of common sources of freshwater salinization exert differential impacts on freshwater bacterial communities.

淡水盐化（Freshwater salinization）是一种普遍存在的水质问题，但其对细菌群落组成与群落组装机制的直接影响此前尚不明确。本研究采用受控实验室实验方法，旨在探究淡水范围内的盐度梯度对细菌群落结构与多样性的影响，并评估作为淡水盐化常见污染源特征的各类单一氯化物是否会对淡水细菌群落产生差异化影响。
