FIGURE 7. Principal component analysis of the environmental conditions for 100 random points within a 10 km buffer surrounding each point of occurrence of Bothriurus asper (green circles and ellipse), Bothriurus aguardente n. sp. (blue triangles and ellipse), and Bothriurus delmari n. sp. (red squares and black ellipse). The ellipses encompass the values within a multivariate t-distribution. Full collors in icons represents an overplotting of 100 points.
