Abstract

Climate change has emerged as a key threat to river ecosystems. This study presents a generic, conceptual framework for assessing the significance of climate change impact for ecological outcomes. Within the framework, multiple sequences of streamflows with a length that is "critical" to target species are derived under current and future climates; ecological responses are assessed using models that consider the influence of flow sequencing; the ranges of ecological responses under future and current climates are compared to indicate the significance of impact. This framework allows the degree of future climate risks to ecosystems to be assessed with reference to the range of behavior under ..
