| Popis: | Bats represent one of the least studied mammal groups in Mongolia, and little is known about the distribution and ecology of species in the country. We surveyed bats in Ikh Nart Nature Reserve, which lies at the intersection of two ecozones in Mongolia, to determine the species present and obtain preliminary data on habitat associations. We conducted mist net surveys at 9 sites, including 4 at natural springs, 2 at human-made wells, and 3 at sites without water, from June to August 2011. We captured 149 individuals representing 3 species, Myotis aurascens, Eptesicus gobiensis, and Vespertilio sp. One species, E. gobiensis , represents a new record for the reserve. We captured all three species at sites near natural springs, only one species, M. aurascens, at human-made well sites, and no bats at sites without water. We also collected basic morphometric measurements for M. aurascens and E. gobiensis . Analysis of morphometric measurements for M. aurascens indicated some sexual dimorphisms. Our results provide a baseline estimate of bats in Ikh Nart and suggest that bat diversity is greater than previously thought. Our results also validate the presence of E. gobiensis and suggest that the species we captured associate mainly with natural water sources. |
