- Title
A null-model for significance testing of presence-only species distribution models.

- Abstract
The article focuses on the species' distribution models (SDMs) to determine the potential distribution of species. Such distribution is predicted through interpolation of identified relationships between species' presence or absence, or presence-only data and the environmental predictors to a geographical area of interest. Such model has been widely used in biogeography, conservation biology, ecology, palaeo-ecology, invasive species studies, and wildlife management. Its accuracy can be validated through several different measures of model accuracy, which includes sensitivity and specificity. The significance of an SDM is measured through its area under the curve (AUC) value against a null distribution of expected AUC values based on random collection data.
