Ecophysiology of Hibernating Eastern Red Bats (Lasiurus Borealis)
… temperate hibernating bats, eastern red bats (Lasiurus borealis) do not utilize typical hibernacula (i.e. caves). Instead, L. borealis will move into leaf litter during the cold bouts of winter months. Because temperatures fluctuate widely at these winter roost sites, my first goal was to …

Movement Ecology and Conservation of the Migratory Bats Lasiurus cinereus and Lasionycteris noctivagans
… frequently killed by wind turbines: hoary bats (Lasiurus cinereus) and silver-haired bats (Lasionycteris noctivagans). Using stable isotopes of nitrogen (δ15N), carbon (δ13C), and hydrogen (δ2H) of the fur of bat carcasses collected at a wind energy facility in south-western Alberta, I determined …

North American Tree Bat (Genera: Lasiurus, Lasionycteris) Migration on the Mid-Atlantic Coast—Implications and Discussion for Current and Future Offshore Wind Development
In eastern North America, "tree bats" (Genera: Lasiurus and Lasionycteris) are highly susceptible to collisions with wind energy turbines and are known to fly offshore during migration. This raises concern about ongoing expansion of offshore wind-energy development off the Atlantic Coast. Season, …

Habitat Use of Urban Bats in Springfield, Missouri
… 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 passive boxes were placed from sunset until …

Red Bat Movement Response to an Ultrasonic Acoustic Deterrent in Flight Cage Trials: Implications for Reducing Bat Fatalities at Wind Facilities
… effectively jamming bat echolocation. Red bats (Lasiurus borealis and Lasiurus blossevillii) are of particular interest as these species are commonly reported at wind energy facilities and existing data indicates UADs are not successful at reducing red bat fatalities. My objective was to compare …

Activity and diet of bats in apple orchards of southern Michigan
… 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 caught in orchards, followed by Diptera, Lepidoptera, …

Ecology of Mid-Atlantic bats after white-nose syndrome: communities, reproduction, and diet within an urban-to-rural gradient
… 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 Region bat communities, I surveyed the area with mist netting and active acoustic sampling (2016–2018) and compared …

Bat Species Diversity in Old-Growth vs. Second Growth Forests in Lilley Cornett Woods, Letcher County, Kentucky
… 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 monitoring was conducted from 22 May - 21 August 2010, …

Ecologia alimentar de morcegos insetívoros de área urbana do município do Rio de Janeiro, RJ (Mammalia: Chiroptera)
… Tadarida brasiliensis (Geoffroy, 1824) and Lasiurus cinereus (Beauvois, 1796) were captured less frequently. It was verified that specimens of M. nigricans and M. molossus captured in urban areas weighted more than those captured in rural and/or wild preserved areas. ldentification of …

Bat occupancy of forests and managed savanna and woodland in the Missouri Ozark Region
… 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 woodland conditions, and control …

Bat Activity Across Urban Forest Plantings in Lexington, Kentucky
… for all phonic groups, except hoary bats (Lasiurus cinereus) which exhibited habitat affinities counter to this. AIC model selection suggested that while various factors influence activity across phonic groups, bat activity was generally greater at plantings with larger-diameter trees. Bat …

Understanding Wind Energy Impacts on Bats and Testing Reduction Strategies in South Texas
… of Brazilian free-tailed bats and hoary bats (Lasiurus cinereus). This was one of the most successful field trials using acoustic deterrents to date. However, my results indicate species-specific responses to deterrents, particularly for yellow bat spp. Therefore, I conclude the technology …

The lure elicited an interesting negative response from NLEB within the illuminated area, but an increase above control conditions beyond the illuminated area. Overall, the UV lure shows promise for increasing detection of bats …
