River flow regimes are changing globally as a consequence of human use of freshwater resources. Additionally, rivers are among the most invaded ecosystems. Invasion biology predicts that the establishment and spread of non‐native species might be favoured both by new environmental regimes (niche opportunities) and by human‐mediated dispersal (propagule pressure). Here, we expand on past research by asking whether these two mechanisms act in isolation or whether they interact to facilitate the spread of non‐natives.

人类河流水流稳定与全美鱼类入侵有关

由于人类对淡水资源的利用，全球河水流向正在发生变化。此外，河流是最受入侵的生态系统之一。入侵生物学预测，新环境制度（适当机会）和人类介导的传播（繁殖压力）都可能有利于非本地物种的建立和传播。在这里，我们通过询问这两种机制是否孤立地起作用或它们是否相互作用以促进非本地人的传播来扩展过去的研究。
