Figure 4.

Native and invasive niches of Nylanderia fulva in different regions; multivariate climatic space was calculated using PCA‐env method. PC1 and PC2 represent the first two axes of the principal competent analysis (PCA). The green and red shadings represent density of species occurrences in different regions; blue represents overlap. Solid and dashed lines show 100% and 50% of the available (background) environment. The red arrows show how the center of the climatic niche for N. fulva (solid) and background extent (dotted) has moved between two ranges.
