備註Abstract

River ecologists are interested in the drift paradox problem, which asks how stream-dwelling organisms can persist, without being washed out, when they are continuously subject to the unidirectional water flow. Water managers are tasked with meeting water needs for industry, agriculture, and urban consumption while mitigating ecosystem impacts. We develop mathematical models that couple hydraulic flow to population growth and dispersal, and we establish theories of persistence metrics, critical domain size, and spreading speeds to describe population persistence and spread in a river environment. We then apply the theories and conduct numerical calculations to analyze how biological, physical and hydrological factors affect population persistence and spread in a river. Our work also provides a mathematical basis for water management.
