Mapping Ponto-Caspian Invaders in GB - WC1048

The Environment Agency has identified 16 species (Table 1) whose potential future distribution is to be mapped across Great Britain. We would use bioclimatic models generated from each species’ known native and invaded ranges to predict bioclimatic suitability within GB. Our methodology has already been used to predict the range of the killer shrimp, Dikerogammarus villosus, and has been approved as a suitable methodology by peer review in a high-ranking international journal (paper Gallardo, Errea & Aldridge (in press) Biological Invasions).

Models will be further refined by overlaying known information on the water chemistry requirements of each species. At the coarsest scale, this can be done through interpolation of water quality for invaded locations in Europe. A more detailed analysis would be possible by searching the literature and contacting experts across Europe. Conducting field surveys would provide the best water quality data, but is outside the scope of this study.
A report would be produced with a predictive map for each species, and a discussion of the patterns and key driving factors that determine distributions. Additional maps would be produced to show the locations of the source data. A summary map of GB would also be produced to show the number of potential species by geography. This ‘heat map’ would help to identify the most vulnerable places in GB to invasion by Ponto-Caspian species, and would also help to focus monitoring efforts.
