Modelling Favourability for Invasive Species Encroachment to Identify Areas of Native Species Vulnerability

Figure 2

Maps (a1) and (b1) show the distribution of both species in Málaga. Filled cells show the presence of Mauremys leprosa in (a1) and of Trachemys scripta in (b1). Black cells correspond to presences taken from Pleguezuelos et al. [15], and gray cells represent presences found during a more recent survey [7]. Maps (a2) and (b2) show the F-Mauremys-Ecogeographical model and F-Trachemys-Encroachment model, respectively. Map (c) shows the intersection between the favourability of both species. Shading ranges from white to black, where white indicates completely unfavourable areas (0) and black indicates completely favourable areas (1).
