Winter Ecology and Ecophysiology of Prairie-Living Big Brown Bats (Eptesicus Fuscus)
… I studied prairie-living big brown bats (Eptesicus fuscus) that overwinter in rock crevices and take flight outside of the hibernacula despite a lack of foraging opportunity. My goal was to describe their winter ecology and behaviour, and investigate reasons for winter flight. I found that …

Division of Investment Between Sons and Daughters in the Big Brown Bat, Eptesicus Fuscus
I also determined whether parents or offspring control the quantity of investment in offspring. Big brown bat mothers allocated resources differently to their sons and daughters and directed higher levels of aggression toward sons than daughters.

A Dietary Study of big brown (Eptesicus fuscus) and northern bats (Myotis septentrionalis) in Western Kentucky
… septentrionalis</em>) and big brown bats (<em>Eptesicus fuscus</em>) in Kentucky. The objective of this study was to determine the prey items consumed by both species at three sites in western Kentucky. Totals of 103 fecal pellet samples from northern bats and 36 fecal pellet samples from big …

The Influence of Reproductive Condition and Roost Type on Thermoregulation and Foraging in Big Brown Bats (Eptesicus Fuscus)
… among reproductive stages in big brown bats (Eptesicus fuscus) that switched between building and tree roosts. I equipped pregnant and lactating bats with temperature sensitive radio-transmitters in southwest Saskatchewan, Canada. While transmitters were active, skin temperature data were …

Availability of Organochlorides and Accumulation in Populations of Tadarida brasiliensis (Free-Tailed Bat) and Eptesicus fuscus (Big Brown Bat)
… on bats such as Tadarida brasiliensis and Eptesicus fuscus have been intensively studied. The effects can range from problems with reproduction to mortality. My analysis of populations of T. brasiliensis and E. fuscus showed that organochlorides are still present in the environment, …

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

Habitat Use of Urban Bats in Springfield, Missouri
… at the reading taken 3 hours after sunset. Eptesicus fuscus activity was significantly 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 …

Activity and diet of bats in apple orchards of southern Michigan
… species of bats were caught: big brown bats (<em>Eptesicus fuscus</em>) and eastern red bats (<em>Lasiurus borealis</em>). Most calls were produced by big brown bats, followed by hoary bats (<em>L. cinereus),</em> red bats, and <em>Myotis</em>. Coleoptera dominated the diet of big brown bats …

Profiling Bat Activity and Species Presence in Managed Longleaf Pine Landscapes
… on the landscape were the big brown bat (<em>Eptesicus fuscus</em>) and eastern red bat (<em>Lasiurus borealis</em>). The data collected in this study will serve as a baseline for bat activity in the region and for evaluating the impacts of the restoration methods on the local bat …

Investigating how bat ectoparasites influence the skin microbiome diversity and composition in Washington State bats
… with ectoparasites than others, especially Eptesicus fuscus (p = 0.0429) and Myotis volans (p = 0.0094). Using next-gen sequencing techniques, we found that ectoparasite infestation did not decrease the skin microbiome diversity of Washington bats (p = 0.965), although bat species (p = …

Roost-Site Selection of Bats in Northeast Missouri With Emphasis on the Endangered Indiana Bat (Myotis Sodalis)
… 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 (N=28), E. fuscus (N=13), and M. lucifugus (N=6). Roost structures varied among species and also in the way in …

Bat occupancy of forests and managed savanna and woodland in the Missouri Ozark Region
… in the Missouri Ozark region: big brown bat (Eptesicus fuscus), eastern red bat (Lasiurus borealis), northern long-eared bat (Myotis septentrionalis), evening bat (Nycticeius humeralis), and tri-colored bat (Perimyotis subflavus). We identified sites that were actively managed for savanna and …

Bats and trees in a managed forest
… and foraging ecology of the big brown bat (Eptesicus fuscus). We captured and tagged male and female big brown bats and used radio telemetry to identify their roosts and track their foraging movements. I used logistic regression to compare the characteristics of roost trees and random trees …

Bat Species Diversity in Old-Growth vs. Second Growth Forests in Lilley Cornett Woods, Letcher County, Kentucky
… (n=6, 23%), big brown bat (<em>Eptesicus fuscus</em>) (n=2), and hoary bat (<em>Lasiurus cinereus</em>) were also captured during mist net surveys. Only 15% of bats were captured in old-growth forest sites, while 85% of captures occurred in second growth forest. Acoustical …

Habitat Use And Nightly Activity Patterns Of Bats On A Military Landscape In Western Kentucky
… most commonly recorded species, big brown bat (Eptesicus fuscus), eastern red bat (Lasiurus borealis), and tri-colored bat (Perimyotis subflavus), activity did not change in response to auditory treatment between nights or within nights (p > 0.05). However, subtle differences in hourly …

Assessing threats to North American bats: impacts of white-nose syndrome and climate on reproduction and survival
… resolved. In the next most abundant species, E. fuscus, estimates of population declines range from 0% to 40%. Wing damage had not been studied prior to WNS, making inferences about the relationship between wing damage and WNS difficult. The effects of WNS on reproduction are unknown. Population …
