Atlas of nonindigenous marine and estuarine species in the North Pacific
Lee Henry II, Deborah A. Reusser
2012, Report
Executive Summary Marine and estuarine nonindigenous species (NIS) are found across the world’s oceans, and designing effective management strategies to mitigate this economic, ecological and human health threat requires a basic understanding of the existing invasion patterns at regional to global scales. However, to date, syntheses at ocean basin scales have...
