Habitat selection by the Northern Long-eared Myotis (<i>Myotis septentrionalis</i>) in the Midwestern United States: Life in a shredded farmscape
نویسندگان
چکیده
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 construct a habitat model of M. septentrionalis in an intensively farmed area in the Midwestern United States, where mortality from white-nose syndrome has not yet been observed. Our study confirms that M. septentrionalis prefers forest and avoids open habitats in this agricultural region. The best landscape variable for predicting activity in woodland sites was the proportion of forest coverage within a radius of 2000 meters. Our analysis indicates that bat activity increased exponentially as forest coverage increased. There is no evidence that M. septentrionalis preferred open areas at the edge of forest (within 5 m of forest edge), or that once in the woods, the distance to the forest edge had any impact on activity.

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...

Population Genetic Structure Within and among Seasonal Site Types in the Little Brown Bat (Myotis lucifugus) and the Northern Long-Eared Bat (M. septentrionalis)
During late summer and early autumn, temperate bats migrate from their summering sites to swarming sites, where mating likely occurs. However, the extent to which individuals of a single summering site migrate to the same swarming site, and vice versa, is not known. We examined the migratory connectivity between summering and swarming sites in two temperate, North American, bat species, the lit...

متن کاملEffects 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...
