Habitat selection and spatial use by the trawling bat Myotis capaccinii (Bonaparte, 1837)

摘要: Habitat selection and spatial use was studied in a population of Myotis capaccinii (Bonaparte, 1837) the eastern Iberian Peninsula during spring 2004. The radio-tracked bats used only aquatic habitats as foraging sites, most activity concentrated on rivers. Rivers were positively selected showed highest preference rank. Pools also but single pool through tracking period. Foraging not evenly distributed along features water surface further determined habitat selection. Open waters with smooth surfaces over cluttered or completely covered by vegetation. This microhabitat is thought to be due greater efficiency prey detection capture open calm waters. Nonetheless, extremely high aggregation individuals observed suggests that distribution might affect location sites Thus, conservation management M. should ensure protection low-flowing stagnant rivers around bats' main caves.
