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)
… body composition in two species of bats (Myotis lucifugus, Pipistrellus subflavus), which are sympatric with M. sodalis and are not endangered. Bats were collected and housed in an environment chamber that mimicked photoperiod, temperature and humidity of their natural hibernacula. Metabolic …

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"
… 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 to …

Information Processing in the Auditory Thalamus of the Echolocating Bat, Myotis Lucifugus: Implications for Fluttering Target Detection
… 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 incoming …

Disease Status, Occupancy, and Relative Activity of Little Brown Bats (Myotis lucifugus) in the Northeastern United States
… >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 to …

Activities Within a Myotine Bat Community With Emphasis on the Endangered Indiana Bat, Myotis Sodalis
… ever found, as well as M. septentrionalis and M. lucifugus. I recorded 144 detector nights yielding 46,588 bat echolocation calls using Anabat II bat detectors. A nested sampling design was used with five habitat types which include upland and lowland sites within each habitat. Calls were …

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 …

Roost-Site Selection of Bats in Northeast Missouri With Emphasis on the Endangered Indiana Bat (Myotis Sodalis)
… additional species: the little brown bat (Myotis lucifugus), northern bat (Myotis septentrionalis), evening bat (Nycticeius humeralis), and big brown bat (Eptesicus fuscus). A total of 183 day-roosts were located throughout the study: M. sodalis (N=91), M. septentrionalis (N=45), N. humeralis …

Habitat Use of Urban Bats in Springfield, Missouri
… 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 bat activity scores. Springfield was divided into five different habitat types in which …

Community ecology of bats in southern lower Michigan, with emphasis on roost selection by myotis
… 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, whereas northern and …

Habitat Use by Boreal Mammals in Response to Salvage Logging After an Insect Outbreak
… (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 bat …

Ecology of Mid-Atlantic bats after white-nose syndrome: communities, reproduction, and diet within an urban-to-rural gradient
… leibii (eastern small-footed bat) and Myotis lucifugus (little brown bat). Impacts to Eptesicus fuscus (big brown bat) populations have been negative, positive or neutral. Migratory bat species such as Lasiurus borealis (eastern red bat) are not impacted by WNS. To determine changes within the …

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 species, …

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
… the Indiana bat and the little brown bat (Myotis lucifugus). Habitat analysis of radio telemetry data and occupancy models of acoustic data were congruent in confirming nocturnal spatial use of forested riparian zones by little brown bats. Additionally, occupancy models of passive versus active …

Assessing the Long-term Impacts of White-nose Syndrome on Bat Communities Using Acoustic Surveys at Fort Drum Military Installation
… 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 of WNS …
