Global risk of invasion by Bactrocera zonata: Implications on horticultural crop production under changing climatic conditions
Fig 2
The collinearity matrix for the candidate predictor variables for Bactrocera zonata.
The collinearity threshold was set at |r|>0.7 according to [61]. Darker shades of blue and red indicate high variable collinearity while lighter shades indicate low collinearity. Similarly, the smaller the circle the lower the correlation value.
