Acoustic sampling considerations for bats in the post-white-nose syndrome landscape
… are not well understood, and although acoustic monitoring is commonly used to monitor these populations, there is limited information about differences among acoustic detectors and the implications to managers thereof. My objectives were to model the relationship between WNS impact, …

Variation In Bat Activity Across Upland Embedded Wetlands In The Cumberland Ranger District Of The Daniel Boone National Forest
… occupancy across natural and constructed UEWs. Acoustic detectors were deployed at 9 natural and 31 constructed UEWs across the Cumberland Ranger District of the DBNF. Each UEW was surveyed across 3 intervals from May – August 2022, and each recording session spanned >3 consecutive nights, …

Bat occupancy of forests and managed savanna and woodland in the Missouri Ozark Region
… to more closed canopy forest. We used Anabat detectors to survey bats during August 2010, May to July 2011, and May to June 2012. We fit single-season occupancy models for each species. We evaluated a priori hypotheses in an information theoretic approach by first evaluating factors affecting …

Bat Activity Across Urban Forest Plantings in Lexington, Kentucky
… 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 surveyed across 8 sampling periods from May – August 2023. Each recording session spanned ca. 7 consecutive nights, …

Long-Term Effects of Forest Harvesting on Habitat Use By Insectivorous Bats
… created by or left after clear-cut logging using acoustic detectors. I revisited the same exact locations 20+ years later to determine how bats use the forest regrowth of these habitats. As was done in 1993-94, I assessed bat community activity and insect community composition (bat prey) in three …

Ecology of northern long-eared bats (Myotis septentrionalis) in a coastal setting after the introduction of White-nose Syndrome
… throughout the summer months through the use of acoustic detectors; (2) relationships between acoustic activity patterns and weather on an hourly basis for several bat species on Long Island, New York; and (3–4) day-roost characteristics and social network dynamics of a coastal northern …

Assessing the effects of prescribed fire on foraging bats at Mammoth Cave National Park after the arrival of White-nose Syndrome
… detection of WNS (2013-2016) using transects of acoustic detectors (Anabat II and Songmeter SM3). Recordings were classified to phonic groups (low, mid, Myotis) and species using automated classifiers (Bat Call Id v.2.7c and Kaleidoscope Pro v.3.1.4B). Subsequent analyses were conducted using bat …

Impacts of Fire on Bats in the Central Appalachians
… bat species. To address this concern we used acoustic detectors to sample bat activity levels in burned and unburned environments to examine habitat and temporal effects of fire on bat species in a repeatedly burned landscape. We found evidence for weak positive fire effects on the northern …

Bat Resource Utilization Along the Potomac River Corridor in Maryland
… 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 River corridor of Maryland and Virginia. For total bat activity, there was significantly more acoustic activity within the …

Habitat Use And Nightly Activity Patterns Of Bats On A Military Landscape In Western Kentucky
… the summers of 2016 and 2017 using full-spectrum acoustic detectors across the Wendell H. Ford Regional Training Center (WHFRTC), a ca. 4200 ha military landscape in the Interior Rivers and Valleys ecoregion of Muhlenberg County in western Kentucky. Local habitat data was collected on site, and …

Assessing the relationships between pollinator-friendly plantings and birds, bats and white-tailed deer on farms in the Coastal Plain of Virginia and Maryland
… Virginia, from April 2017- November 2019 using acoustic detectors. Of total detections, 20.11% were identified as big brown bat (Eptesicus fuscus), 17.97% evening bat (Nycticeius humeralis), 15.35% silver-haired bat (Lasionycteris noctivagans), 7.11% eastern red bats (Lasiurus borealis), 3.66% …
