Invasive non-native species are widespread in freshwaters but their capacity to establish in new lakes has seldom been assessed. In this fouryear study (2006–2009), we used Side-scan Sonar and underwater video to illustrate how a 200 ha urban, amenity lake at Cardiff Bay (Wales, UK) was invaded extensively by zebra mussels Dreissena polymorpha (Pallas) within 2–3 years of creation in 2001. Veli...

Invasive species are increasingly becoming a policy priority. This has spurred researchers and managers to try to estimate the risk of invasion. Conceptually, invasions are dependent both on the receiving environment (invasibility) and on the ability to reach these new areas (propagule pressure). However, analyses of risk typically examine only one or the other. Here, we develop and apply a joi...

Invasive bivalves can cause widespread ecological damage, but eradication has proved difficult. Identifying the pathways of dispersal is crucial to implementing more effective biocontainment measures. We examined distribution highly invasive zebra mussel (Dreissena polymorpha) in Great Britain through Species Distribution Modelling determine drivers and generated suitability maps predict future...
