Historical explanation of genetic variation in the Mediterranean horseshoe bat Rhinolophus euryale (Chiroptera: Rhinolophidae) inferred from mitochondrial cytochrome-b and D-loop genes in Iran

Modeling habitat suitability of bats to identify high priority areas for field monitoring and conservation

Bats provide important ecosystem services but face severe threats due to land and climate changes. Although bats are an important component of mammal diversity in Iran, the ecology of many species remains virtually unstudied in the country. Here we applied the maximum entropy approach to model habitat suitability of bat species in Iran, identify the most important variables for their distribution, predict high priority areas for field monitoring and conservation, and estimate the coverage of the bat species' suitable habitats by the existing protected areas. We created a richness map for the twelve species to identify high priority areas for field monitoring and conservation. The results of species distribution modeling showed that Pipistrellus kuhlii (828,977.2 km²) and Miniopterus pallidus (646,581.9 km²) had the largest distribution ranges and Rhinopoma microphyllum (211,202.7 km²) and Rousettus aegyptiacus (218,278.6 km²) had the smallest distribution ranges in Iran. By averaging the importance of each ecological variable across the 12 species, we found that distance to forests (with a negative association) is the most important ecological driver of bat distribution in Iran. The Zagros Mountains were identified as a hotspot of bats based on the distribution of the 12 species. Our findings showed that small proportions of each species suitable habitats were covered by protected areas and protected suitable habitats varied from 3.2%for Pipistrellus kuhlii to15.9% for Tadarida teniotis. This study highlights the importance of forests for bat conservation showing that forest conservation is a high priority in the country. Areas which have the highest richness should be prioritized for field monitoring and conservation.

Bat fauna and conservation assessment of Kurdistan caves, Iran

The populations of cave-dwelling bat species are encountering a remarkable decline all over the world. To plan effective conservation projects for bats and their cave roosts, collecting data on their distribution in a particular region is essential. Furthermore, developing an applicable index that incorporates both biotic and abiotic parameters relevant to caves is useful to prioritize caves for conservation management. Recently, there has been a growing interest in studying bat fauna of Iran. The Kurdistan province in west of the country is entirely mountainous, having a suitable geological substratum for formation of caves. Previously, five bat species were reported from Kurdistan. The current study has improved the data by doubling the number of cave-dwelling bat species of the province. A total number of 61 records of 10 species were documented. Overall, of 28 caves studied, 26 caves were used by bats. Each cave hosted one to six bat species. To prioritize Kurdistan caves for conservation programs, the Bat Cave Vulnerability Index (BCVI) was employed for 26 caves explored in this study. Four caves, including Karaftu, Kamtaran, Darvish Ouliya, and Kouna Sham-Sham, were highlighted due to their highest BCVI value. The other 22 caves received medium or low priority values. In the current study, we provided data on the bat fauna of Kurdistan caves, in addition to evaluate their conservation priorities by applying an assessing index for the first time in the country.
