Classification and Processing of Communication Calls in Little Brown Bats, Myotis Lucifugus
In chapter 4, I investigated subcortical structures (i.e., thalamus and IC) involved in the processing of communication signals, using egr1 (an immediate early gene) as a molecular marker for brain activation. Three species-specific signals were included -- downward FM (DFM), courtship, and …

Ambient Temperature Effects on Metabolism and Body Composition in Torpid Bats (Myotis Lucifugus and Pipistrellus Subflavus)
Recent declines in Indiana bat (Myotis sodalis) populations have been well documented but unexplained. It is unclear if declines are caused by exposure to and accretion of environmental contaminants, the loss of summer roosting habitat, changes in cave microclimate, or other detrimental factors. An …

Arousal patterns, fungal loads, and wing damage in a surviving population of little brown bats (Myotis lucifugus)
<p>Little brown bats (<em>Myotis lucifugus</em>) at Tippy Dam in Michigan have shown resilience to white-nose syndrome (WNS), which is caused by the fungus Pseudogymnoascus destructans. This study evaluated the impact of environment (temperature and moisture), pathogen virulence, and host …

"""White Noise"" Non-Linear Analysis of Inferior Colliculus Neural Responses in the Little Brown Bat, Myotis Lucifugus"
… of auditory neurons from a species of FM bat, Myotis lucifugus. The consistently short (1-5 ms) duration of echolocation calls emitted by the little brown bat, Myotis lucifugus, permitted approximating the sounds heard during hunting with a train of short, constant-duration pulses. In contrast …

Information Processing in the Auditory Thalamus of the Echolocating Bat, Myotis Lucifugus: Implications for Fluttering Target Detection
… auditory cortex (AC) of the echolocating bat, Myotis lucifugus. Specifically, the tonic discharge patterns present in the IC are transformed into phasic patterns in the AC. There is also a degradation in the capacity for AC neurons to entrain their discharges to the temporal waveform of …

Disease Status, Occupancy, and Relative Activity of Little Brown Bats (Myotis lucifugus) in the Northeastern United States
… 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, habitat associations in a post-WNS landscape, and the extent …

Habitat Use by Boreal Mammals in Response to Salvage Logging After an Insect Outbreak
… coyotes (Canis latrans), and little brown bats (Myotis lucifugus) in response to salvage logging after a bark beetle outbreak in Yukon, Canada. I monitored species occupancy in beetle-affected forests and salvage-logged stands of different tree retention levels and ages using wildlife cameras and …

Exploring the drivers and consequences of emerging infectious disease of wildlife
… stabilization of the little brown bat (Myotis lucifugus), finding that host-pathogen coexistence in this system is the product of their complex interaction. In Chapter 3, I characterize the range-wide variation in white-nose syndrome impacts on a federally endangered and poorly studied …

Changing Relationship Between Temperature and Pathogen Growth on Bats with White-nose Syndrome
… destructans (Pd), in little brown bats (Myotis lucifugus) across a spatiotemporal gradient. We explored the relationship between bat roosting temperatures and Pd growth rates across three phases of pathogen invasion comprising years since WNS has been present at sites: invasion (0-3), …

Assessing the impacts of white-nose syndrome induced mortality on the monitoring of a bat community at Fort Drum Military Installation
… of the presence of the endangered Indiana bat (Myotis sodalis), acoustic monitoring is now likely more effective than traditional capture methodologies. In the summers of 2011 and 2012, I implemented intensive acoustic sampling using Anabat detectors at Fort Drum to develop a summer acoustic …

Assessing the Long-term Impacts of White-nose Syndrome on Bat Communities Using Acoustic Surveys at Fort Drum Military Installation
… of bat species, such as the little brown bat (Myotis lucifugus) in the Northeast, to assess ongoing temporal and spatial changes, habitat associations, and as a guide to direct future mist-netting should rely more on relative activity as the metric of choice. Furthermore, the continuous spread …

Roost-Site Selection of Bats in Northeast Missouri With Emphasis on the Endangered Indiana Bat (Myotis Sodalis)
… 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 to the similarities in roost-site characteristics of forest-dwelling species of bat, and potential for niche-overlap, I also …

Habitat Use of Urban Bats in Springfield, Missouri
… higher in the urban environment while Myotis septentrionalis activity was significantly higher in rural environments. For Myotix lucifugus, M. grisescens, M. sodalis, Lasiurus borealis, L. cinereus and Nycticeius humeralis there were no significant differences between urban and rural …

Ecology of Mid-Atlantic bats after white-nose syndrome: communities, reproduction, and diet within an urban-to-rural gradient

Bat Species Diversity in Old-Growth vs. Second Growth Forests in Lilley Cornett Woods, Letcher County, Kentucky
… species were captured. The little brown bat (<em>Myotis lucifugus</em>) was the most abundant bat captured (n=11, 42%). The tri-colored bat (<em>Permyotis subflavus</em>) (n=6, 23%), northern bat (<em>M. septentrionalis</em>) (n=6, 23%), big brown bat (<em>Eptesicus fuscus</em>) (n=2), and hoary …

Bat Resource Utilization Along the Potomac River Corridor in Maryland

Nevertheless, there are difficulties with studying the movement of insectivorous bats due to their small …

Assessing threats to North American bats: impacts of white-nose syndrome and climate on reproduction and survival
… knowledge of the effects of WNS comes from M. lucifugus because it is one of the most abundant North American species, and is also heavily affected by WNS (population declines > 90%). Aside from estimates of rates of population declines at hibernation sites, the effects of WNS on species other …

Bat Habitat Ecology Using Remote Acoustical Detectors at the Army National Guard Maneuver Training Center - Fort Pickett, Blackstone, Virginia
Bats occupy diverse and unique niches and are regarded as important components in maintaining ecosystem health. They are major consumers of nocturnal insects, serve as pollinators, seed disperser, and provide important economic benefits as consumers of agricultural and forest pest insects. Bats …
