From: The global risk of infectious disease emergence from giant land snail invasion and pet trade
Geographical patterns of invasion risk A, B and pet trade C, D in giant land snail, Lissachatina fulica. A Forecast of global climatic suitability for L. fulica based on an ensemble of seven algorithms using 19 climatic variables reduced to five axes using a principal component analysis. Model’s performance was high (TSS = 0.87). B Human population density where L. fulica occurs (native and invasive range) compared to background occurrences (i.e. records of other terrestrial gastropods inside the climatically suitable area for L. fulica). Small maps depict the location of occurrences for each group (L. fulica native = 61, L. fulica invasive = 1480, background = 115,162).
