This book was released on 2015 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hoary bat is a migratory, foliage-roosting bat with a mostly solitary roosting habit. Little is known about the social interactions of this species, but as a solitary roosting bat, most interactions between conspecifics are thought to involve mating behavior or territorial disputes. Developing a more complete understanding of the social behavior of this species may provide critical insight to reduce and manage the high fatality rates from wind turbines during the fall migration and mating season. I tested the response of hoary bats to conspecific social call playback during the spring and fall migration to: 1) test whether conspecific social call broadcasting attracts or repels individual bats; 2) examine whether there are seasonal differences in these responses; and 3) describe the structure and variation of recorded social calls. I conducted trials along migration routes in New Mexico, during the spring northward migration, and California, during the fall southward migration. Hoary bats were attracted to social call broadcasting during both the spring and fall migration. A lack of females detected at study sites precluded the determination of sex-specific responses. Hoary bats used these calls during the spring migration, when only males were present, suggests a social function not associated with mating. While calls were variable in frequency and length, there was no evidence of distinct syllables or types of calls. Conspecific call broadcasting can be used as an acoustic lure to aid in capturing hoary bats, and can thus assist subsequent investigations of this extremely elusive and difficult to study species.

Available in PDF, EPUB and Kindle. Book excerpt: Bats are highly gregarious mammals that have been extensively studied for their ability to echolocate (i.e., gain information from the echoes of ultrasonic calls) to navigate and find food. Perhaps less well studied are social vocalizations, which bats use to communicate with conspecifics. Some bat species have been shown to possess rich vocal repertoires, supporting intricate social interactions. While the roost is likely where the majority of a bat's social interactions occur, on account of higher densities, there are also behavioral contexts that occur predominantly, if not solely in flight, that are associated with social calls. Bats exhibit an extensive range in social group size, social group organization, and mating systems, making them interesting for comparative, phylogenetically controlled analyses. Group size is often correlated with vocal complexity, as more complex vocalizations can encode more information about individual identity. Vocal learning has been observed in some species of bats. The full vocal repertoires of relatively few bat species have been studied thus far, as they are nocturnal, volant animals that produce predominately ultrasonic vocalizations. With more data available, bats would be a very useful taxon for studying the evolution of social communication, as they exhibit not only a high diversity of social group size and complexity but also sophisticated vocalizations. Social vocalizations can be structurally diverse and are highly important for bat sociality. Calls often vary notably between species. Research in this field has barely scratched the surface, and there is still much to learn about social communication in bats.

Available in PDF, EPUB and Kindle. Book excerpt: "Bats could be a useful study system for studying the evolution of social communication, as they exhibit a high diversity of social group size and complexity. However, the study of bat social calls has been limited, as they are nocturnal, volant animals that produce predominately ultrasonic vocalizations. Passive acoustic monitoring studies occasionally capture bat in-flight social calls. The information from surrounding echolocation calls can provide information on species identity, abundance, and foraging activity. I used passive acoustic monitoring in Greensboro, North Carolina, to identify seven types of in-flight social calls from Eptesicus fuscus, Lasiurus borealis, Lasiurus cinereus, Nycticeius humeralis, Perimyotis subflavus, and Tadarida brasiliensis. Eptesicus fuscus, N. humeralis, and T. brasiliensis differed in total social call production, and the proportional use of call types. Shared called types exhibited species-specific signatures. The presence of species-specific signatures indicates bats could potentially discern signaler identity. Social call production was highest early in the night and positively correlated with bat activity. Eptesicus fuscus and T. brasiliensis most commonly produced complex calls, which appear to mediate social interactions between conspecifics while foraging. Nycticeius humeralis most commonly produced downsweeps, which appear to be broad-functioning contact calls. Upsweeps exhibited a similar context to downsweeps, and were commonly produced by E. fuscus and N. humeralis. My results indicate bats use dedicated social calls to mediate different types of social interactions while in flight."--Abstract from author supplied metadata

Download or read book Autumn Roost Selection by Male Hoary Bats Lasiurus Cinereus in Northern California written by Danielle Salganek and published by . This book was released on 2019 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hoary bat, Lasiurus cinereus, is a solitary bat that roosts in the foliage of trees throughout the western hemisphere. Roosts are subject to the ambient temperature of their surroundings, thus hoary bats undergo long-distance migrations between summer and winter ranges to avoid freezing temperatures. Habitat selection has been studied during the summer for maternal female hoary bats, but not during migration and winter. Autumn migration coincides with the hoary bat mating period and it has been proposed that male and female bats may rendezvous on migration paths. Individuals may select roosts in stopover locations that enhance fitness by providing shelter, forage, or mating opportunities. Because of prior evidence that species of Lasiurusand other long-distance migrating bats forage infrequently at stopover locations, I hypothesized hoary bats select stopover habitat during autumn migration which minimizes energetic expenditures and improves mating opportunities. Specifically, I hypothesized that hoary bats would select areas with greater solar radiation and southwest aspects to exploit temperature at roosts in the autumn afternoons and that they might select roosts that serve as a landmark during migration i.e., emergent trees. I also hypothesized that they would roost in close proximity to flyways to increase mating opportunities (behavior demonstrated by previous studies).

This book was released on 2007-09-27 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The generation of electricity by wind energy has the potential to reduce environmental impacts caused by the use of fossil fuels. Although the use of wind energy to generate electricity is increasing rapidly in the United States, government guidance to help communities and developers evaluate and plan proposed wind-energy projects is lacking. Environmental Impacts of Wind-Energy Projects offers an analysis of the environmental benefits and drawbacks of wind energy, along with an evaluation guide to aid decision-making about projects. It includes a case study of the mid-Atlantic highlands, a mountainous area that spans parts of West Virginia, Virginia, Maryland, and Pennsylvania. This book will inform policy makers at the federal, state, and local levels.

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 Biosonar written by Annemarie Surlykke and published by Springer. This book was released on 2014-07-19 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two groups of animals, bats and odontocetes (toothed whales), have independently developed the ability to orient and detect prey by biosonar (echolocation). This active mechanism of orientation allows these animals to operate under low light conditions. Biosonar is a conceptual overview of what is known about biosonar in bats and odontocetes. Chapters are written by bat and odontocetes experts, resulting in collaborations that not only examine data on both animals, but also compare and contrast mechanisms. This book provides a unique insight that will help improve our understanding of biosonar in both animal groups.

Available in PDF, EPUB and Kindle. Book excerpt: Every three years a major international conference on bats draws the leading workers in the field to a carefully orchestrated presentation of the research and advances and current state of understanding of bat biology. Bats are the second most populous group of mammalia species, after rodents, and they are probably the most intensively studied group of mammals. Virtually all mammologists and a large proportion of organismic biologists are interested in bats. The earlier two edited books deriving from previous bat research conferences, as well as this one, have been rigorously edited by Tom Kunz and others, with all chapters subjected to peer review. The resulting volumes, published first by Academic Press and most recently by Smithsonian, have sold widely as the definitive synthetic treatments of current scientific understanding of bats.
