Using the Ensemble Modeling Approach to Predict the Potential Distribution of the Muscat Mouse-Tailed Bat,Rhinopoma muscatellum(Chiroptera: Rhinopomatidae), in Iran

Habitat suitability models can be generated using methods requiring information on presence of species or presence and absence of species.Rhinopoma muscatellumis one of the six mouse-tailed bats (Rhinopomatidae) and is known as an extremely frequent bat in Iran. In this study, 76 presence points were identified and recorded in distribution range of species. Presence-only (Domain, Bioclim, and one-class SVM) and presence/pseudo-absence (P/PA) data-based methods were used to model the distribution ofR. muscatellumin Iran. In this study, in order to establish the pseudo-absence points, the output of presence-only map with the highest validity on AUC statistics was used. Using the output of the Domain method map (AUC = 0.8), 720 pseudo-absence points of the species were designed and entered into the P/PA models, including generalized linear model (GLM), maximum entropy (MaxEnt), maximum likelihood (MaxLike), classification and regression trees (CART), rough set, back-propagation artificial neural networks (BP-ANN), and two-class support vector machine (two-class SVM). The models were validated by the kappa coefficient of agreement as a threshold-based index. The coefficient of agreement was measured above 0.8 for all running models. Then, all binary maps were entered into the ensemble method, and the distribution map was presented as the output map with the result of ten implemented models. In order to evaluate the effect of each habitat variable on species distribution, sensitivity was measured by logistic regression method. The results of the modeling showed that the southeastern, southern, and southwestern regions of the country have a high suitability for this species, which was also confirmed by the ensemble modeling method. Based on the sensitivity results, the maximum temperature of the warmest months of the year, mean daily temperature, and distance from the mines had the highest effect on species distribution. The results of this study showed thatR. muscatellumdistribution models can be useful in identifying the species habitat suitability and the distribution maps obtained from these models can be considered as a suitable tool for population studies.
