Journal ArticleDOI
AUC: a misleading measure of the performance of predictive distribution models
TL;DR: The area under the receiver operating characteristic (ROC) curve, known as the AUC, is currently considered to be the standard method to assess the accuracy of predictive distribution models as discussed by the authors.
Journal ArticleDOI
The crucial role of the accessible area in ecological niche modeling and species distribution modeling
Narayani Barve,Vijay Barve,Alberto Jiménez-Valverde,Andrés Lira-Noriega,Sean P. Maher,A. Townsend Peterson,Jorge Soberón,Fabricio Villalobos +7 more
TL;DR: This paper explored the conceptual and empirical reasons behind choice of extent of study area in such analyses, and offer practical, but conceptually justified, reasoning for such decisions, and asserted that the area that has been accessible to the species of interest over relevant time periods represents the ideal area for model development, testing, and comparison.
Journal ArticleDOI
Threshold criteria for conversion of probability of species presence to either–or presence–absence
TL;DR: Four threshold criteria are compared for a wide range of sample sizes and prevalences, modeling a virtual species in order to avoid the omnipresent error sources that the use of real species data implies.
Journal ArticleDOI
Use of niche models in invasive species risk assessments.
Alberto Jiménez-Valverde,Alberto Jiménez-Valverde,Andrew Townsend Peterson,Jorge Soberón,J. M. Overton,Pedro Aragón,Jorge M. Lobo +6 more
TL;DR: This work highlights that, in the case of invasive species, distributional predictions should aim to derive the best hypothesis of the potential distribution of the species by using all distributional information available, including information from both the native range and other invaded regions.
Journal ArticleDOI
Not as good as they seem: the importance of concepts in species distribution modelling
TL;DR: This work discusses three important topics that must be kept in mind when modelling species distributions, namely the distinction between potential and realized distribution, the effect of the relative occurrence area of the species on the results of the evaluation of model performance, and the general inaccuracy of the predictions of the realized distribution provided by species distribution modelling methods.
