Bat activity over wetlands: temporal and spatial variation
… well as spatially. For temperate insectivorous bats, wetlands are important forage habitats because they provide water and high abundances of insects. My overall objective was to identify abiotic and biotic factors that influence bat foraging activity over wetlands in the channeled scablands of …

Bat Activity Across Urban Forest Plantings in Lexington, Kentucky
… habitat for forest-dependent wildlife such as bats. My research focused on assessing differences in bat activity across a 20-year chronosequence of RTB sites. Acoustic detectors were deployed across 10 different-aged plantings at 60 randomly-defined detector locations. Each planting was …

Profiling Bat Activity and Species Presence in Managed Longleaf Pine Landscapes
… of the longleaf pine (<em>Pinus palustris</em>). Bats inhabit key ecological niches in forest ecosystems, including the longleaf pine ecosystem, and can be indicators of ecosystem condition. This study investigated the effects of current forest management practices and landscape management history …

The Effects of Prescribed Fire on Bat Activity in the Ozark National Scenic Riverways
… forests. The effects of prescribed fire on bats are not fully understood and impacts vary depending on species life history and habitat requirements. This study was conducted to further the understanding of how bat communities, with emphasis on federally protected species, may be affected by …

Influence of habitat and bat activity on moth community composition and seasonal phenology across habitat types
… within and between habitats and mediates the activity of insectivorous bats is understudied. Previous research into the impact of bat activity on moths has primarily focused on interactions in a single habitat type or a single moth species of interest, leaving a large knowledge gap on how …

Variation In Bat Activity Across Upland Embedded Wetlands In The Cumberland Ranger District Of The Daniel Boone National Forest
… in past decades to provide habitat for bats and other wildlife. This research focused on identifying differences in bat activity and occupancy across natural and constructed UEWs. Acoustic detectors were deployed at 9 natural and 31 constructed UEWs across the Cumberland Ranger District …

Changes in the seasonal activity of bats occuring in the Kunene region, Namibia: Influence of environmental factors
… how environmental conditions affect bat activity, number and distribution is important for assessing activity and abundance. Monthly bat activity and the effect of environmental factors (temperatures, moon phase) on bat activity were recorded to elucidate factors influencing the …

Habitat Use And Nightly Activity Patterns Of Bats On A Military Landscape In Western Kentucky
<p>Bat populations of eastern North America continue to decline due to the cumulative effects of White-nose Syndrome, habitat loss, and anthropogenic disturbances across the landscape. Unique stressors exist on military installations, such as noise created during training activities. Given the …

Utilizing Acoustic Methods to Identify Bat Species, and to Assess Their Habitat Use and Perception of Owls
… area in Ohio. Increasing our knowledge about bats, a vulnerable taxon, in this diverse region is critical due to a decline in bat populations caused by habitat loss and fragmentation, wind energy, and White-nose Syndrome. To address this need my thesis research was focused on: 1) comparing the …

Assessing the effects of prescribed fire on foraging bats at Mammoth Cave National Park after the arrival of White-nose Syndrome
<p>Habitat use of bats may shift following population level impacts of White-nose Syndrome (WNS). Multiple bat species have experienced unprecedented population declines due to WNS, including federally listed Myotis sodalis (Indiana bat) and Myotis septentrionalis (northern long-eared bat). …

Assessing the Long-term Impacts of White-nose Syndrome on Bat Communities Using Acoustic Surveys at Fort Drum Military Installation
… of White-nose Syndrome (WNS)-affected bat species, increased reliance on acoustic monitoring is now the new "normal". As such, the ability to accurately identify individual bat species with acoustic identification programs has become increasingly important. Additionally, how bat …

Impacts of Fire on Bats in the Central Appalachians
… how the re-introduction of fire will affect bat community assemblages, particularly after the severe White-nose Syndrome related population declines of many cave-hibernating bat species. To address this concern we used acoustic detectors to sample bat activity levels in burned and unburned …

Habitat Use of Urban Bats in Springfield, Missouri
<p>During the summers of 1998-2000, the Anabat II bat detector system was placed in a mosaic of habitats within Springfield, Missouri and surrounding rural areas in southern Missouri to compare the activity indices of nine bat species between urban and rural environments. A total of 1,876 …

Spatial urban and peri-urban biodiversity patterns
… was used: the groups of birds, butterflies and bats were studied, as they are considered good indicators of environmental change. Their diversity patterns and community structure were investigated, in order to determine the way they are influenced by landscape composition (land cover) and …

Bat Resource Utilization Along the Potomac River Corridor in Maryland
… use and population responses. The response of bats to periodical cicadas is largely unknown. Using a before-after-control-impact study design, we deployed ultrasonic acoustic detectors during the summers of 2020–2022 within and just outside the range of the cicada emergence along the Potomac …

The ecology and conservation of cave roosting bats in the Yorkshire Dales
… an important assemblage of underground bat sites, but prior to this study nothing was known about the ecology of cave use. Between 2002 and 2005,53 cave entrances were logged for swarming activity using automated echolocation call loggers. A subset was chosen for continuous monitoring …

Spatial and Temporal Activity of Migratory Bats at Landscape Features
… important features for navigation of migrating bats although spatial and temporal activity may depend on species-specific migration strategies. I predicted that latitudinal migrating bats would have higher activity along north-south oriented linear landscape features, especially during …

Activity and diet of bats in apple orchards of southern Michigan
<p>I studied activity and diet of bats in apple orchards in southern Michigan. There was no difference between organic and conventional orchards in number and composition of insects captured with light traps, number of bats captured with mist nets, or number of acoustic files of bat activity that …
