"""White Noise"" Non-Linear Analysis of Inferior Colliculus Neural Responses in the Little Brown Bat, Myotis Lucifugus"
… is the primary means by which insectivorous bats orient in flight and capture insect prey. FM bats, whose calls consist of a short (1-5 ms) frequency-modulated (FM) sweep, were chosen for this study. The goal of these experiments was to develop techniques for efficiently characterizing …

Disease Status, Occupancy, and Relative Activity of Little Brown Bats (Myotis lucifugus) in the Northeastern United States
… catastrophic declines in several North American bat species, including >90% losses in Little Brown Bats (Myotis lucifugus). Because small, remnant populations persist across the Northeast and Mid-Atlantic, there are key questions about their continued vulnerability to WNS or other pathogens, …

Bat Species Diversity in Old-Growth vs. Second Growth Forests in Lilley Cornett Woods, Letcher County, Kentucky
<p>Bat activity in old-growth forests (+150 years) is a subject that is poorly understood. The majority of old-growth forests are located in the northwestern portion of the United States, and with current silviculture practices, many forests are being cut. There have been no published studies that …

Community ecology of bats in southern lower Michigan, with emphasis on roost selection by myotis
… niche of three sympatric species of Myotis (little brown bat, M. lucifugus; northern bat, M. septentrionalis; and Indiana bat, M. sodalis) and examined changes in composition of the entire bat community in southern Lower Michigan over long periods. Little brown bats roosted in buildings, …

Exploring the drivers and consequences of emerging infectious disease of wildlife
… Each chapter explores these processes in bat populations of North America, predominantly the Northeast and Midwest regions of the United States, impacted by the emerging fungal pathogen that causes white-nose syndrome, Pseudogymnoascus destructans. In Chapter 2, I disentangle the effects …

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 …

Assessing the impacts of white-nose syndrome induced mortality on the monitoring of a bat community at Fort Drum Military Installation
… the northeastern U.S. in 2006, several affected bat species have exhibited marked population declines (> 90%). For areas such as Fort Drum in northern New York that are subject to regulatory mandates because of the presence of the endangered Indiana bat (Myotis sodalis), acoustic monitoring is …

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 …

Roost-Site Selection of Bats in Northeast Missouri With Emphasis on the Endangered Indiana Bat (Myotis Sodalis)
Roosts are an integral habitat component for bat species and may dictate their survival and fitness. I used radiotelemetry to study the roosting ecology of the endangered Indiana bat, Myotis sodalis, at Deer Ridge Conservation Area (DRCA) in northeast Missouri from May through August 2001-2002. Due …

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 …

Ecology of Mid-Atlantic bats after white-nose syndrome: communities, reproduction, and diet within an urban-to-rural gradient
… syndrome (WNS) has reduced the abundance of many bat species within the United States' mid-Atlantic region, including the endangered Indiana (Myotis sodalis), threatened Myotis septentrionalis (northern long-eared bat) and other bats of conservation concern, such as Perimyotis subflavus …

Assessing the relationships between pollinator-friendly plantings and birds, bats and white-tailed deer on farms in the Coastal Plain of Virginia and Maryland
… (Meleagris gallopavo)), resident and migratory bats, and white-tailed deer (Odocoileus virginianus) are of interest to both landowners and conservation managers. First, we studied bird species diversity, presence, density, and nesting on farms planted with and without pollinator-friendly …
