Niche Overlap of Congeneric Invaders Supports a Single-Species Hypothesis and Provides Insight into Future Invasion Risk: Implications for Global Management of the Bactrocera dorsalis Complex

Figure 4

Niche metrics calculated for Bactrocera spp. Ecological Niche Models.

a) Niche breadth (Levin’s B) for 10 replicates of each final ENM projected to mainland southern Africa (see Fig. 5a). Note: DPP = B. dorsalis + B. philippinensis + B. papayae. b) Niche overlap (Schoener’s D) between ENMs projected to mainland southern Africa (see Fig. 5a): A = B. invadens & B. invadens De Meyer et al. (2010); B = B. invadens & B. dorsalis; C = B. invadens & B. dorsalis + B. philippinensis + B. papayae (DPP); D = B. invadens & All four species combined.
