Winter Use of a Rock Crevice by Northern Long-Eared Myotis (Myotis septentrionalis) in Nebraska

Current status of the Northern Long-eared Myotis (<i>Myotis septentrionalis</i>) in northwestern Nebraska

The Northern Long-eared Myotis (Myotis septentrionalis; Order: Chiroptera) occurs in eastern, southern, and northern Nebraska, but its current distribution in northwestern parts of the state is unclear due to its recent arrival to the region. We investigated the status of this species in the Pine Ridge via mist net (2011-2014) and acoustic surveys (2014). We documented nine species of bats in t...

Internal Cavity Characteristics of Northern Long-eared Bat (Myotis septentrionalis) Maternity Day-roosts

Effects of Hierarchical Roost Removal on Northern Long-Eared Bat (Myotis septentrionalis) Maternity Colonies

Forest roosting bats use a variety of ephemeral roosts such as snags and declining live trees. Although conservation of summer maternity habitat is considered critical for forest-roosting bats, bat response to roost loss still is poorly understood. To address this, we monitored 3 northern long-eared bat (Myotis septentrionalis) maternity colonies on Fort Knox Military Reservation, Kentucky, USA...

Habitat selection by the Northern Long-eared Myotis (<i>Myotis septentrionalis</i>) in the Midwestern United States: Life in a shredded farmscape

Populations of the Northern Long-Eared Myotis (Myotis septentrionalis) have declined dramatically in recent years in eastern North America due to white-nose syndrome. Although M. septentrionalis was once common in parts of eastern North America, few studies have examined habitat selection of this species in an agricultural landscape. We used acoustical methods to quantify bat activity and const...

Acoustic evidence of bats using rock crevices in winter: A call for more research on winter roosts in North America

The Northern Long-eared Myotis (Myotis septentrionalis) is known to hibernate in mines and caves, often using cracks within these hibernacula as roost sites. We hypothesized that M. septentrionalis might use deep cracks in rock outcrops for hibernation as well. To test this hypothesis, we placed acoustical bat detectors near rock outcrops away from any known mines or caves during winter in Nebr...
