Dramatic decline in population abundance of Salvelinus leucomaenis after a severe flood and debris flow in a high gradient stream

摘要

A dramatic change in population abundance of Salvelinus leucomaenis following a catastrophic flood event was investigated. Population density declined by c. 98% after the flood in a river section affected by debris flow. The isolation of the affected population and habitat change caused by flooding may have impeded population recovery. (c) 2006 The Author.
