Download or read book Roost Selection and Seasonal Activity of a Remnant Population of Northern Myotis Myotis Septentrionalis in Pennsylvania written by Mattea A. Lewis and published by . 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.

Download or read book Bats of Texas written by Loren K. Ammerman and published by Texas A&M University Press. This book was released on 2012-04-25 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: With all new illustrations, color photographs, revised species accounts, updated maps, and a sturdy flexible binding, this new edition of the authoritative guide to bats in Texas will serve as the field guide and all-around reference of choice for amateur naturalists as well as mammalogists, wildlife biologists, and professional conservationists. Texas is home to all four families of bats that occur in the United States, including thirty-three species of these important yet increasingly threatened mammals. Although five species, each represented by a single specimen, may be regarded as vagrants, no other state has a bat fauna more diverse, from the state’s most common species, the Brazilian free-tailed bat, to the rare hairy-legged vampire. The introductory chapter of this new edition of Bats of Texas surveys bats in general—their appearance, distribution, classification, evolution, biology, and life history—and discusses public health and bat conservation. An updated account for each species follows, with pictures by an outstanding nature photographer, distribution maps, and a thorough bibliography. Bats of Texas also features revised and illustrated dichotomous keys accompanied by gracefully detailed line drawings to aid in identification. A list of specimens examined is located at batsoftexas.com.

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 1999-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: The timing could not be better for addressing riparian area management and the resulting impacts of surface water. The Forest Service leadership team has identified water and watershed management as the issue of the upcoming decade. These factors and more have moved riparian forests to the forefront of environmental management. Riparian Management in Forests of the Continental Eastern United States gives you the tools you need to take on this task. Each day, thousands of natural resource professionals face the problems involved in managing riparian forests. The challenge: fragmented ownership, fragmented ecosystems, and diverse interest groups. The solution requires a multidisciplinary approach, drawing on a complex mix of government agencies, private interests, and local communities as exemplified in the following initiatives: Chesapeake Bay Program "Save the Bay" Inland West Water Strategy New York City Watershed Project The Pacific Habitat Strategy The Anadromous Fish Habitat Riparian Management in Forests of the Continental Eastern United States summarizes the state-of-the-art in the management of forested riparian areas. It serves as a desktop reference for natural resource administrators, educators, and on-the-ground managers from industry, consulting firms, and municipal, state, and federal agencies who routinely face the complex problems of protecting riparian areas.

Download or read book Bats in the Anthropocene Conservation of Bats in a Changing World written by Christian C. Voigt and published by Springer. This book was released on 2015-12-07 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on central themes related to the conservation of bats. It details their response to land-use change and management practices, intensified urbanization and roost disturbance and loss. Increasing interactions between humans and bats as a result of hunting, disease relationships, occupation of human dwellings, and conflict over fruit crops are explored in depth. Finally, contributors highlight the roles that taxonomy, conservation networks and conservation psychology have to play in conserving this imperilled but vital taxon. With over 1300 species, bats are the second largest order of mammals, yet as the Anthropocene dawns, bat populations around the world are in decline. Greater understanding of the anthropogenic drivers of this decline and exploration of possible mitigation measures are urgently needed if we are to retain global bat diversity in the coming decades. This book brings together teams of international experts to provide a global review of current understanding and recommend directions for future research and mitigation.
Download or read book Selection of Day Roosts by Female Long legged Myotis Myotis Volans in Forests of the Central Oregon Cascades written by Patricia Ormsbee and published by . This book was released on 1996 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measuring habitat selection by bats is complicated by their intricate life cycle. Scaling habitat measurements to reflect a hierarchal habitat selection process can help to define habitat associations of bats. I assessed day roost habitat of female long-legged myotis at four scales: the roost structure, micro-habitat surrounding the roost, the stand level, and landscape level. I radio-tracked 16 female long-legged myotis (Myotis volans) for an average of eight days per bat, July through August of 1993, 1994, and 1995 in two drainages in the central Oregon Cascades (Quentin Creek and Lookout Creek) to locate day roost structures. Forty-one day roost structures were identified, of which 1 was a rock face, 4 were green trees, and 36 were snags. The average height of all roost structures was 40 m (SE=2.5). The average dbh for all snags and trees used as day roosts was 100 cm (SE=6.1). Large snags including partially live, hollow western redcedar trees (Thuja plicata) averaging 97 cm dbh (SE=6.6) and 38 m (SE=2.8) high were the most commonly used roost structures. Individuals radio-marked at the same night roost did not use one common day roost. Individual bats were found roosting in one roost for several days, or using multiple day roosts within discrete roost areas. The area which encompassed one night roost and all known day roosts covered 3,258 ha in the Quentin Creek drainage and 6,391 ha in Lookout Creek. I compared physical characteristics and habitat within 20 meters of 33 roost snags with 66 randomly selected snags. The odds that a snag is used as a day roost is associated with roost height; given height, the odds of use is associated with the height of the stand within 20 meters of the snag. There is some indication that the presence of an open canopy around the snag, and the percentage of bark on the snag also could be factors that influence the selection of snags as day roosts. The frequency of occurrence of roost structures within young and late seral stands did not differ from what was expected to occur by chance in these two stand conditions. Roosts did not occur in stands with a harvest history vs. stands without a harvest history disproportionate to availability. I compared the distance to class I (largest) through class IV (smallest) streams between 34 day roosts and 102 randomly selected points. Day roosts were located closer to streams than randomly selected locations in both Lookout and Quentin Creek drainages with 1 exception (Lookout class III). In two cases day roosts were significantly closer to streams than randomly selected locations. Day roosts tended to be closer to streams where night roosts were located than did randomly selected points, regardless of stream class.
