MODELING THE EXPANSION OF THE INVASIVE CHINESE POND MUSSEL
The Chinese pond mussel Sinanodonta woodiana is native to eastern Asia, but is now a widespread invasive species throughout Europe. S. woodiana is a large bivalve, with shell lengths as large as 200 mm. S. woodiana can impact ecosystems through high densities (100 ind m-2 ), wet biomasses (up to 33 kg m-2 ), or through mass mortality events,. We used Maximum Entropy modeling to predict the potential distribution of S. woodiana in Europe using bioclimatic variables, and known locations from its invasive range from both the Global Biodiversity Information Facility and published literature. Mean annual temperature was the strongest predictor of habitat suitability. Our model predicts that the climate is suitable for S. woodiana throughout Europe, including areas where it is not yet widespread, such as the Iberian Peninsula, or not yet established, such as the British Isles. Ongoing work is modeling the potential distribution of S. woodiana for Europe, North America, and South America using points from both its native range and invasive range in order to assess whether the invasive lineage has different abiotic tolerances or has adapted to cooler temperatures.
