Abstract

Glen Canyon National Recreation Area covers large and geographically unique regions of southern Utah and northern Arizona. However, multiple surveys of bats from 1952 to 2017 have not been published. Prior to 2015, most bat surveys in the recreation area were conducted using mist nets only and did not include acoustic monitoring. In this paper we compile records of bats found in Glen Canyon National Recreation Area from 1952 to 2017, including records from our recent surveys using both mist nets and acoustic sampling. During our recent surveys, 2 new species were captured (Nyctinomops macrotis and Lasionycteris noctivagans), and 2 other new species were documented using acoustic detection (Myotis evotis and Eumops perotis), bringing the total documented bat species in Glen Canyon National Recreation Area to 17 species. This paper sheds light on the diverse bat assemblage of Glen Canyon National Recreation Area that will serve as a baseline for future research and conservation efforts.


El Área Nacional de Recreación Glen Canyon cubre geográficamente grandes y únicas regiones del sur de Utah y norte de Arizona. Sin embargo, varias encuestas sobre murciélagos que datan de 1952 a 2017 no han sido publicadas. Antes de 2015, la mayoría de estas encuestas se realizaron utilizando un método de red de niebla el cual no incluía monitoreo acústico. En esta investigación hemos copilado registros de murciélagos encontrados en El Área Nacional de Recreación Glen Canyon de 1952 a 2017, incluimos registros de nuestras encuestas más recientes utilizando tanto el método por red de niebla como el monitoreo acústico. Durante el estudio más reciente se capturaron dos nuevas especies (Nyctinomops macrotis y Lasionycteris noctivagans), y otras dos nuevas se documentaron utilizando la detección acústica (Myotis evotis and Eumops perotis), resultando un total de 17 especies documentadas de murciélagos en Área Nacional de Recreación Glen Canyon. Este estudio sirve de orientación sobre el diverso conjunto de murciélagos sobre esta área que servirá como base para futuras investigaciones.
