Fig. 3 in Susceptibility of tropical mountain forests to biological invasions from the temperate and subtropical zone, exemplified by Zonitoides (Gastropoda: Gastrodontidae)

Fig. 3. Climatic suitability for (a) Zonitoides arboreus s.l.; and (b) Zonitoides nitidus on the Malaysian Peninsula, Sumatra and Borneo, based on Mahalanobis distances. The higher the threshold, the more dissimilar are the climatic conditions to those of the majority of known occurrences.>100% means that the climatic conditions are dissimilar to those of any available record. The new records for the species (white circles) were not included in the calculation of the climatic suitability.
