Results of mantel and partial mantel test of landscape genetics of the gecko Oedura lesueurii, with a listing of variables included in the models (number of rivers [River] and number of roads [Walking track; Dirt Road; Paved Road; All road] between sites, minimum elevation between sites sites [min. elevation], mean elevation of sites minus the minimum elevation between sites [Mean elevation - min. elevation], straight-line distance [Distance] and true distance between sites [True distance]), the number of parameters per model, R2(total variance explained by the model), coefficient of correlation, P-value of parameters (The level of significance for our tests was set at α = 0.0028 (Bonferroni correction; i.e. 0.05/18 = 0.0028, where 18 represents the number of tests performed), AIC, Δ AIC, and AIC weight
