Climate change and invasive species are two of the greatest threats to global biodiversity, and their impacts are compounded when they interact with each other1. For example, altered flow regime as a result of climate change is one of the major pathways by which alien species are introduced into new aquatic ecosystems2, while storms and associated flooding increase their dispersal through escapes from aquaculture facilities3.

Abstract


Climate change and invasive species are two of the greatest threats to global biodiversity, and their impacts are compounded when they interact with each other1. For example, altered flow regime as a result of climate change is one of the major pathways by which alien species are introduced into new aquatic ecosystems2, while storms and associated flooding increase their dispersal through escapes from aquaculture facilities3.
