Aim: To provide an overview of ecology and management of invasive species in riverine ecosystems.
● Aquatic invasive species are a primary threat to streams and rivers across the globe, impacting biodiversity, disrupting key ecological functions, and compromising ecosystem services.
● Invasive species are those that are transported out of their native range, introduced into a novel location, establish self-sustaining populations by surviving and reproducing, spread to new locations, and have negative ecological and/or economic impacts in the recipient ecosystem.
● Species can enter a new region by being imported as or with a commodity associated with the direct human movement of goods, by hitchhiking on human modes of transport, and by dispersing unaided by themselves along infrastructure corridors.
● The likelihood of nonnative species to establish new self-sustaining populations depends on propagule pressure, biological attributes of the species, environmental characteristics of the ecosystem, and biotic interactions with recipient communities.
● The ecological impacts of aquatic invasive species are manifested at different scales from genes to ecosystems.
● Aquatic invasive species have caused enormous economic impacts associated with their management and mitigation of their damages.
● A diversity of management strategies and policy options are available to prevent, contain, control and eradicate aquatic invasive species.
Conclusions: The future health of riverine ecosystems will depend on how societies manage current invasive species and whether the arrival of future invasive species can be successfully prevented, or their impacts minimized.
