Background: Drought is a natural disturbance of aquatic and terrestrial ecosystems in many regions worldwide and can be a major factor in structuring aquatic communities. Drought frequency and intensity is expected to increase due to climate change and can also be exacerbated by water withdrawals and other human impacts. Individuals through ecosystems can be impacted by drought disturbance, but I will focus on population and community dynamics. I will discuss hydrology and drought, the potential role of climate change, fish refuge use and population dynamics in drying streams, the influence of flow regime and drought on fish assemblage structure and stability, and modeling effects of climate change and drought on fish and crayfish species persistence.
