ABSTRACT: Effigy Mounds National Monument is a nationally-protected park along the Mississippi River in northeastern Iowa that contains diverse topography and associated upland and lowland forests interspersed with upland prairie. The park is home to at least seven bat species, the Federally Threatened Myotis septentrionalis is one of those and is the focus of this research. M. septentrionalis is one of the species being impacted by White-nose syndrome, which is a deadly pathogen of bats caused by the fungus Pseudogymnoascus destructans (Pd). Spatial and temporal patterns of bat communities were evaluated using acoustic detection and mist-netting methods. Exposure to Pd by all captured bat species was determined via swabbing the muzzles of captured bats and testing the isolated DNA. Currently, the exposure rate is ~5%. Finally, roost-site habitat characteristics for female Myotis septentrionali was determined using telemetry. Several Myotis septentrionalis were tracked to their nesting trees in 2015 and 2016. Comparison of summer roost site habitat to park-wide available habitat indicates little selection beyond tree height. Our results suggest that Pd is present at the park and that Effigy Mounds National Monument is an important protected area for bats, especially Myotis septentrionalis.
