This book was released on 2020 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The decline in northern myotis (Myotis septentrionalis) populations since the arrival of white-nose syndrome (WNS) in eastern North America has led to the species receiving protected status in the United States and Canada. Much of the research on habitat use of this species has occurred during the summer maternity season while similar examinations of autumn and winter habits are scarce. The goal of my thesis was to describe the seasonal presence and habitat use of a remnant colony of northern myotis in central Pennsylvania. From 2017–2020, I radio-tagged 27 northern myotis and used acoustic bat detectors at 5 locations to study roost habitat choice and seasonal changes in activity. Radio-tagged northern myotis never left the study area and were tracked to day roosts until early November. Counts of bats exiting roost trees revealed that maternity roosts were as frequently used during autumn (August 15–October 31) as during summer (21 June–August 14). Similarly, 78% of roost trees located during autumn were used during the summer as well. Using model selection and multinomial logistic regression models, I found that tree decay stage, basal area of the forest stand, and distance to water best described the variance in male roosts, female roosts, and randomly sampled trees. Both male and female northern myotis preferred to roost in dead and declining trees. Females also preferred to roost in dense forest stands and in trees located close to water. During October and November, one radio-tagged female and one male northern myotis were tracked to a ground-level rock crevice. Acoustic activity recorded between February and October at this location differed from trends in activity at other sampling locations and had a peak of activity in late summer when northern myotis are known to swarm. Northern myotis calls were recorded at this roost between March and October and bats were observed emerging from this roost during spring and autumn but not summer. These data support the growing evidence that northern myotis hibernate outside of caves and show that bats in central Pennsylvania roost in maternity trees until at least late October.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Energygass Savannah River Site supports a diverse bat community. Nine species occur there regularly, including the eastern pipistrelle (Pipistrellus subflavus), southeastern myotis (Myotis austroriparius), evening bat (Nycticeius humeralis), Rafinesquegass big-eared bat (Corynorhinus rafinesquii), silver-haired bat (Lasionycteris noctivagans), eastern red bat (Lasiurus borealis), Seminole bat (L. seminolus), hoary bat (L. cinereus), and big brown bat (Eptesicus fuscus). There are extralimital capture records for two additional species: little brown bat (M. lucifigus) and northern yellow bat (Lasiurus intermedius). Acoustical sampling has documented the presence of Brazilian free-tailed bats (Tadarida brasiliensis), but none has been captured. Among those species common to the Site, the southeastern myotis and Rafinesque's big-eared bat are listed in South Carolina as threatened and endangered, respectively. The presence of those two species, and a growing concern for the conservation of forest-dwelling bats, led to extensive and focused research on the Savannah River Site between 1996 and 2002. Summarizing this and other bat research, we provide species accounts that discuss morphology and distribution, roosting and foraging behaviors, home range characteristics, habitat relations, and reproductive biology. We also present information on conservation needs and rabies issues; and, finally, identification keys that may be useful wherever the bat species we describe are found.

Book excerpt: Determination of characteristics of trees and habitats used by different bat species is necessary to complete a basic understanding of the ecology and interactions of tree-roosting bats and to develop management plans for forested areas. During the summers of 1999 and 2000, 5 male Indiana bats (Myotis sodalis) and 2 male and 5 female northern bats (M. septentrionalis) were mist-netted and subsequently radio-tracked to 14 and 21 roost trees, respectively, on the Wayne National Forest (NF) in Ohio.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Delineating habitat preferences, especially those of imperiled species, is critical to ensure that species have access to resources needed to persist. In addition to overall preferences, establishing the phenology of sensitive periods such as reproduction can be challenging for small, cryptic species such as bats. We conducted an empirical study in northeast Wyoming, USA, to characterize the habitat selection of northern long-eared bats (Myotis septentrionalis). Objectives in Chapter 1 were to (1) characterize the maternity roost-site preferences of endangered northern long-eared bats in a peripheral population occurring within a forest managed for timber harvest, and (2) determine whether roost-site preferences and switching were modulated by weather conditions. Chapter 2 objectives were (1) to assess whether maternity roost trees of northern long-eared bats are used for multiple years in northeast Wyoming; (2) to determine whether intra-seasonal occupation of maternity roosts in northeast Wyoming matches the timing of seasonal protections for northern long-eared bats; and (3) to assess the efficacy of motion-triggered game cameras for determining occupancy of maternity roosts. In our first chapter, we found that bats were more likely to select quaking aspens, snags, and trees relatively large in diameter; however, these preferences were modulated by daily weather conditions and reproductive state. Bats roosted more often in pine at warm temperatures and while lactating, and in snags when solar radiation was high and precipitation low. Bats preferred forest patches with higher canopy cover and a larger proportion of snags. In our second chapter, we documented colony occupation at maternity roosts across multiple years and outside of the protected season of June—July. We also recorded rarely documented behaviors, including pup carrying, with motion-triggered game cameras. Our findings provide guidance on habitat types that would be beneficial to conserve for northern long-eared bat populations, and more broadly, that context-dependence is an important consideration for habitat-selection studies. Peripheral populations may be critical for future recovery of declining species; however, seasonal protections against habitat disturbance may be mismatched with the phenology of populations at range edges.
Download or read book Bat Roosts in Trees written by Bat Tree Habitat Key and published by Pelagic Publishing Ltd. This book was released on 2018-11-19 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a guide to finding tree-roosts. It is the result of the collaborative efforts of professional surveyors and amateur naturalists across Europe as part of the Bat Tree Habitat Key project, and represents a combination of firsts: It is the first time legislation and planning policy have been reviewed and put to practical use to define an analysis framework with clearly identifiable thresholds for action. Yet, despite its efficacy in a professional context, it is also the first time a guide has been produced that is equally effective in achieving its objective for amateurs. It is the first time such a method has been evidence-supported throughout, with summary reviews of each aspect of the roosting ecology of the individual 14 tree-roosting species, with illustrative photographs and data to which the reader has open access. It is the first time a repeatable analysis framework has been defined against which the surveyor may compare their results at every stage, from the desk-study, through ground-truthing, survey and analysis, thereby ensuring nothing is overlooked and that every result can be objectively compared. The survey and analysis framework itself is ground-breaking in that it may readily be adapted for any taxa; from moths, through amphibians, reptiles, birds and all other mammals. Used diligently, these methods will reward disproportionately and imbue the reader with renewed confidence as they quickly progress from beginner to competency. Thus, this book is for everyone who has ever wanted to find a tree-roost, or to safeguard against inadvertently damaging one.
Download or read book Bats in Forests written by Michael J. Lacki and published by JHU Press. This book was released on 2007-05-11 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although bats are often thought of as cave dwellers, many species depend on forests for all or part of the year. Of the 45 species of bats in North America, more than half depend on forests, using the bark of trees, tree cavities, or canopy foliage as roosting sites. Over the past two decades it has become increasingly clear that bat conservation and management are strongly linked to the health of forests within their range. Initially driven by concern for endangered species—the Indiana bat, for example—forest ecologists, timber managers, government agencies, and conservation organizations have been altering management plans and silvicultural practices to better accommodate bat species. Bats in Forests presents the work of a variety of experts who address many aspects of the ecology and conservation of bats. The chapter authors describe bat behavior, including the selection of roosts, foraging patterns, and seasonal migration as they relate to forests. They also discuss forest management and its influence on bat habitat. Both public lands and privately owned forests are considered, as well as techniques for monitoring bat populations and activity. The important role bats play in the ecology of forests—from control of insects to nutrient recycling—is revealed by a number of authors. Bat ecologists, bat conservationists, forest ecologists, and forest managers will find in this book an indispensable synthesis of the topics that concern them.

This book was released on 2000 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bat conservation is often hindered by a lack of geographic-specific knowledge of the bat community and the characteristics of roost sites used by reproductive females. I assessed the composition of the bat community and examined the use and characteristics of roosts selected by reproductive female big brown bats (Eptesicusfuscus) and long- eared myotis (Myotis evotis) in the Channeled Scablands of northeastern Washington. This area contains a high diversity of potential roost types (snag and tree cavities and rock and human-made structures) known to be used by both species of bats. I trapped 536 bats representing 10 species during 1996-97 using mist nets and harp traps. Radio-telemetry was used to locate 38 and 35 roosts of reproductive female big brown bats and long-eared myotis, respectively. Both species switched roosts frequently. Habitat variables were measured at three levels; the roost site, a random site near the roost, and a random site at a landscape level. Ninety-five percent (n = 36) of the big brown bat roosts were in natural tree cavities. Twenty-eight roosts were in ponderosa pine (Pinus ponderosa) and eight in aspen (Populus tremuloides). Dead tops of live pine trees were used significantly more as roosts than pine snags by big brown bats. Although there were significantly more roost trees>30 cm in diameter and taller than 12m than what was available, they were not necessarily the tallest tree in the stand. A significantly greater proportion of big brown bat roosts were found in open pine, aspen and mixed-aspen pine forests and less in grasslands and closed pine than expected. Obstruction of roost trees was not different than randomly selected trees. Big brown bat roost sites were not significantly different in forest structure than random sites. All but one of the 35 long-eared myotis roost sites were found in crevices in small basalt rock formations. Long-eared myotis roosts were in open habitats close to the edge of closed forest stands. Both species selected roosts in an area with a greater proportion of aspen and open ponderosa pine habitat. Forest restoration strategies should protect both large diameter snags but also existing dead top trees and should maintain natural population levels of biological agents that create dead tops. Restoration of historic open conditions in ponderosa pine will provide improved habitat for both big brown bats and long-eared myotis. Caution must be exercised in making generalizations about roost selection of individual bat species, given regional differences found in this and other studies.

Dearborn and published by . This book was released on 2017 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: While bottomland hardwoods used to encompass a large portion of the south-central United States, due to clear cutting for agriculture and other purposes, the amount of bottomland hardwoods present has been reduced by almost 88 percent from its previous extent. At the same time, bat surveys in the Midwest after the arrival of white-nose syndrome (WNS) have shown declines in populations of Indiana bats (Myotis sodalis), northern long-eared bats (Myotis septentrionalis), little brown bats (Myotis lucifigus), and tri-colored bats (Perimyotis subflavus). Due to these threats to bat populations, it is important to gain information on how various bat species in the Midwest United States utilize the landscape within bottomland hardwood ecosystems in order to inform conservation efforts. There were two main objectives to this study. First, we sought to determine which roost site characteristics influence selection of a roost location by individuals in maternity colonies of Indiana bats. Second, we wanted to evaluate which habitat characteristics influenced occupancy of morphologically similar species within bottomland hardwood ecosystems in the Midwest United States: Myotis species, tri-colored bats, and evening bats (Nycticeius humeralis).
