Discharge is a key determinant of biodiversity in rivers. Positive relationships between riverine biodiversity and discharge, also called species–discharge relationships (SDRs), have been widely documented. However, potential human influences on these relationships are typically not considered. We aimed to fill this gap by exploring whether and how the slopes and intercepts of global riverine fish SDRs might be affected by human pressure on the environment.

河流鱼类物种丰富度和人类存在的全球一致性

排放是河流生物多样性的关键决定因素。河流生物多样性与流量之间的正相关关系，也称为物种流量关系 (SDR)，已被广泛记录。但是，通常不会考虑人对这些关系的潜在影响。我们旨在通过探索全球河流鱼类 SDR 的斜率和截距是否以及如何受到人类对环境的压力的影响来填补这一空白。
