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.

Download or read book Sociality in Bats written by Jorge Ortega and published by Springer. This book was released on 2016-06-07 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides new insights into the social behavior of bats - one of the most fascinating topics currently being pursued by researchers. After an introduction reviewing the history of research in bat behavioral ecology, it covers three major themes: bat sociality per se (Part I), bat communication (Part II), and ecological aspects (Part III). Part I offers a concise overview of the social organization and systems of bats, introducing readers to the complexity and dynamics of group structures. Part II is devoted to the innovative field of social communication, focusing on bat songs, dialects and calls. Part III discusses the influence of the environment on bat behavior, particularly with regard to roosting and foraging. This book addresses the needs of researchers working in behavioral sciences, evolution and ecology.

Download or read book Function of Social Calls in Brown Long eared Bats Plecotus Auritus written by Stephanie E. Murphy and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Microchiropteran bats produce vocalisations for two purposes: echolocation and communication. Vocalisations used for communication are often referred to as social calls. In this thesis I examined the nature of Brown Long-eared bats Plecotus auritus social calls recorded at roost and foraging sites through a combination of recording and playback experiments. A total of 11,484 social calls were recorded at 20 maternity roosts sites and three types of vocalisations were dentified on the basis of shape, referred to as Type A, B, and C. Although Type A vocalisations shared the same basic pattern, it was a very large group within which there was a lot of variation in acoustic parameters. Principal component analysis and modelbased cluster analysis were used to look for patterns within this group, and this identified six clusters. Maternity colonies surveyed in this study varied in size from as few as nine up to 98 bats, and the number of social calls recorded at the roost sites was highly correlated with the numbers of bats present in the colony. The analysis of seasonal patterns of social call production revealed that the number of social calls recorded at maternity roost sites showed a linear increase from June to September, whereas, the number of bats emerging decreased sharply from August to September. Simulations of P. auritus social calls were used to investigate behavioural responses to calls away from roost sites using the Autobat. P. auritus were clearly much more responsive to simulations of their own species' social calls than to the other stimuli tested. This strongly suggests that the responses to the Autobat represent attempts to interact with the source of the stimulus. Recording with ultrasound and infra-red video was conducted to test the bats' responses to the different types of synthesised call and whether these responses varied seasonally. A female's approach response to the stimulus may represent an attempt to repel a perceived intruder from her foraging area. Alternatively, if calls were used to coordinate foraging by advertising the location of resources to other females that share the range, a response may represent an attempt to move towards such resources. Experiments showed that females were significantly more likely to respond to a stimulus produced within their core foraging area, than in the peripheral area, or outside their foraging area. On the other hand, while females regularly shared foraging ranges with other females, there was little evidence of co-ordination of movements between simultaneously radio-tracked dyads. It was concluded that responses to the stimuli probably represent attempts to repel perceived intruders from the foraging area. The thesis concludes with a discussion of some of the advantages and limitations of using play-back of synthesised social calls in the field to investigate vocal communication in bats. Ways in which studies of captive bats of known relatedness could be used to further elucidate the functions of social calls are discussed.

Book excerpt: Arguably biosonar is one of the ‘eye-opening’ discoveries about animal behavior and the auditory systems of echolocators are front and center in this story. Echolocation by bats has proven to be a virtual gold mine for colleagues studying neurobiology, while providing many rich examples of its impact on other areas of bats’ lives. In this volume we briefly review the history of the topic (reminding readers of the 1995 Hearing by Bats). We use a chapter on new findings in the phylogeny of bats to put the information that follows in an evolutionary context. This includes an examination of the possible roles of Prestin and FoxP2 genes and various anatomical features affecting bat vocalizations. We introduce recent work on the role of noseleafs, ears, and other facial components on the focusing of sound and collection of echoes. ​

Download or read book How nature shaped echolocation in animals written by Mariana L Melcón and published by Frontiers E-books. This book was released on 2014-11-24 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Echolocation has evolved in different groups of animals, from bats and cetaceans to birds and humans, and enables localization and tracking of objects in a dynamic environment, where light levels may be very low or absent. Nature has shaped echolocation, an active sense that engages audiomotor feedback systems, which operates in diverse environments and situations. Echolocation production and perception vary across species, and signals are often adapted to the environment and task. In the last several decades, researchers have been studying the echolocation behavior of animals, both in the air and underwater, using different methodologies and perspectives. The result of these studies has led to rich knowledge on sound production mechanisms, directionality of the sound beam, signal design, echo reception and perception. Active control over echolocation signal production and the mechanisms for echo processing ultimately provide animals with an echoic scene or image of their surroundings. Sonar signal features directly influence the information available for the echolocating animal to perceive images of its environment. In many echolocating animals, the information processed through echoes elicits a reaction in motor systems, including adjustments in subsequent echolocation signals. We are interested in understanding how echolocating animals deal with different environments (e.g. clutter, light levels), tasks, distance to targets or objects, different prey types or other food sources, presence of conspecifics or certain predators, ambient and anthropogenic noise. In recent years, some researchers have presented new data on the origins of echolocation, which can provide a hint of its evolution. Theoreticians have addressed several issues that bear on echolocation systems, such as frequency or time resolution, target localization and beam-forming mechanisms. In this Research Topic we compiled recent work that elucidates how echolocation – from sound production, through echolocation signals to perception- has been shaped by nature functioning in different environments and situations. We strongly encouraged comparative approaches that would deepen our understanding of the processes comprising this active sense.

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 Handbook of Mammalian Vocalization written by Stefan M Brudzynski and published by Academic Press. This book was released on 2009-12-08 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Mammalian Vocalization is designed as a broad and comprehensive, but well-balanced book, written from the neuroscience point of view in the broad sense of this term. This well-illustrated Handbook pays particular attention to systematically organized details but also to the explanatory style of the text and internal cohesiveness of the content, so the successive chapters gradually develop a consistent story without losing the inherent complexity. Studies from many species are included, however rodents dominate, as most of the brain investigations were done on these species. The leading idea of the Handbook is that vocalizations evolved as highly adaptive specific signals, which are selectively picked up by the brain. The brain serves as a receptor and behavioural amplifier. Brain systems will be described, which allow vocal signals rapidly changing the entire state of the organism and trigger vital biological responses, usually also with accompanying emission of vocalizations. Integrative brain functions leading to vocal outcome will be described, along with the vocalization generators and motor output to larynx and other supportive motor subsystems. The last sections of the Handbook explains bioacoustic structure of vocalizations, present understanding of information coding, and origins of the complex semiotic/ semantic content of vocalizations in social mammals. The Handbook is a major source of information for professionals from many fields, with a neuroscience approach as a common denominator. The handbook provides consistent and unified understanding of all major aspects of vocalization in a monographic manner, and at the same time, gives an encyclopaedic overview of major topics associated with vocalization from molecular/ cellular level to behavior and cognitive processing. It is written in a strictly scientific way but clear enough to serve not only for specialized researchers in different fields of neuroscience but also for academic teachers of neuroscience, including behavioural neuroscience, affective neuroscience, clinical neuroscience, neuroethology, biopsychology, neurolingusitics, speech pathology, and other related fields, and also for research fellows, graduate and other advanced students, who widely need such a source publication.

Download or read book Acoustic Ecology of European Bats written by Michel Barataud and published by Companyédition Biotope/MNHN. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bats, being nocturnal flying mammals, have developed a special and very efficient means of navigating in the dark: the sonar. Although the acoustic signals they emit are inaudible to the human ear, they can be perceived, recorded and analysed with appropriate equipment and software. This book is a product of the knowledge and skill acquired by its author over more than two decades of constant research on the subject of ultrasound detection. The initial, purely auditory, approach is complemented by the computed-assisted analysis of the ultrasonic signals. With the method described in this book, a bat detector and a computer, the reader will be able to identify about 85% of bat acoustic records in Europe, carry out bat inventories and other more in-depth surveys without disturbing the animals. Thirty-five of the 42 European bat species, including all the most widespread species, are covered.

Download or read book Social Calls of the Bats of Britain and Ireland written by Neil Middleton and published by Pelagic Publishing Ltd. This book was released on 2022-07-26 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: The social calls of bats are an area about which relatively little is known, with more research still required to expand our understanding. However, these calls are increasingly recognised as a useful aid to identification: they appear to be species specific and are indicative of behaviour – as in territorial activity of males during the mating season. Because the gathering and interpretation of bat echolocation data are a matter of course during research, conservation and consultancy, it is a logical progression to build momentum behind the consideration of social calls in mainstream bat-related work. A better understanding of this subject could mean that non-intrusive survey methods are developed, ensuring that what is being observed is, as far as possible, purely natural behaviour. In turn this will contribute to better interpretation and more suitable mitigation, compensation and/or enhancement solutions. The book summarises what is understood so far about social calls of the bat species occurring in Britain and Ireland, and north-west Europe. This new edition has been updated and expanded throughout, now containing: foreword by the bat authority Michel Barataud, author of Acoustic Ecology of European Bats almost double the number of figures and tables as appeared in the first edition completely overhauled call library, all in full spectrum format, with new additional examples three entirely new chapters, covering bat-related acoustics, settings for social interaction, and survey guidelines The material will be useful to people carrying out bat studies, at whatever level and for whatever purpose, and will also encourage others to undertake further research. What's more, social calls are fascinating to listen to: they are, after all, produced with listeners in mind (other bats). In light of this, the book is accompanied by an extensive downloadable library of sound files which offer a unique gateway into the private life of bats.

Download or read book Social Calls of the Bats of Britain and Ireland written by Neil Middleton and published by Pelagic Publishing Ltd. This book was released on 2014-09-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bats are fascinating mammals about which we still have much to learn. As well as using ultrasonic echolocation calls for orientation and while foraging, they also have a complex array of vocalisations for communication. These are known as social calls and are an essential component of their colonial lifestyle. This book brings together the current state of knowledge of social calls relating to the bat species occurring within Britain and Ireland, with some additional examples from species represented elsewhere in Europe. It includes access to a downloadable library of calls to be used in conjunction with the book. Downloadable call library Social calls are complex and intriguing to listen to; they are after all produced with listeners in mind (other bats). To enjoy and fully appreciate social calls the reader must also have the opportunity to become a listener: each of the presented sonograms in the book is cross-referenced to downloadable ‘time expanded’ .wav sound files which are contained within a much wider library of calls for you to explore. Included in Social Calls of the Bats of Britain and Ireland The authors start with an overview of the species of bats in Britain and Ireland (Chapter 1), and then introduce us to communication within the social world of bats (Chapter 2). Referencing the latest research, the authors explore how these calls can be classified according to their structure, and in many cases the context in which the calls are thought to be emitted (Chapter 3). Chapter 4 addresses aspects of survey methodology to be considered by those studying social calls. This leads on to the analysis of calls (Chapter 5), detailing the specific methods used and parameters commonly measured by researchers. The final, and main chapter (Chapter 6) introduces the 23 species covered in the book giving each a detailed profile including: habitat preferences, typical roosting locations, roost emergence times, mating strategies and maternity behaviour. Each species profile includes what is known about the social calls for that species and this text is supported by colour sonograms (created using Pettersson BatSound V4.1) of most of the calls discussed. Each sonogram is linked to a .wav sound file (Time Expansion x10) within the downloadable library. The sound files allow the reader to hear, as well as see, the calls produced using any bat sound analysis software that supports the .wav format. The authors conclude with a bibliography and an extensive list of references directly cross-referenced throughout the book.

Available in PDF, EPUB and Kindle. Book excerpt: Neuroendocrine Regulation of Animal Vocalization: Mechanisms and Anthropogenic Factors in Animal Communication examines the underpinning neuroendocrine (NE) mechanisms that drive animal communication across taxa. Written by international subject experts, the book focuses on the importance of animal communication in survival and reproduction at an individual and species level, and the impact that increased production and accumulation of endocrine-disrupting chemicals (EDCs) can have on these regulatory processes. This book discusses sound production, perception, processing, and response across a range of animals. This includes insects, fish, bats, birds, nonhuman primates, infant humans, and many others. Some chapters analyze how neuroactive substances, endocrine control, and chemical pollution affect the physiology of the animal’s perceptive and sound-producing organs, as well as their auditory and vocal receptors and pathways. Other chapters address the recent approaches governments have taken to protect against the endocrine disruption of animal (vocal) behaviors. The book is a valuable resource for researchers and advanced students seeking first-rate material on neuroendocrinological effects on animal behavior and communication. Serves as the most comprehensive cross-taxa study of its kind, revolutionary in its focus on the impacts of EDCs on the processes guiding animal communication Emphasizes the importance of production, perception and processing of acoustic vocalization for survival Analyzes recent governmental policies and protections against the effects of EDCs on humans and wildlife

Download or read book Is That a Bat written by Neil Middleton and published by Pelagic Publishing Ltd. This book was released on 2020-01-13 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bat detector surveys are carried out by ecological consultants, researchers, conservationists and hobbyists. Understanding and categorising non-bat sounds in surveys offers the potential of knock-on benefits for informing development projects (e.g. other important records discovered within a site), as well as the possibility of associated conservation benefits. In recent years the number of people carrying out these surveys and recording calls with bat detectors has grown considerably. These surveys often generate vast amounts of audio recordings, resulting in the heavy workload associated with completing the sound analysis and reporting process. Those carrying out analysis can be distracted, intrigued or delayed owing to the occurrence of recordings that are unfamiliar and not identifiable to them. These recordings can relate to ‘difficult to ID’ bat species, but also, often, sounds not related to bats. This can be especially true when noise triggers such as insects, small mammals or birds look like bat-related noise. Therefore, only knowing what bats sound like is not enough. It is extremely useful to know what other sources of noise look and sound like within the same soundscape. This resource will help bat workers, in whatever environment they are in, to be more confident in recognising, categorising and dismissing other sounds. The book includes a substantial downloadable sound library (.wav format) that readers can listen to by ear or process through sound analysis software. Is That a Bat? also caters for sounds that are also heard by ear alone, in the field, during the hours of darkness. These scenarios often have bat surveyors intrigued or confused as to what they are listening to. Occasionally, knowing what these sounds are could be important, or at the very least, of interest. The first chapter caters for the subject overall, including suggestions from the author as to why the subject matter is of value. It also discusses bat-related calls (including social calls) with a view to offering comparisons against the other sources of sound discussed in separate chapters. Continuing through the book, there are chapters covering the following: small mammals; amphibians; insects; birds; electrical/mechanical noise; and other noise/nuisances. Within each chapter there are sub-sections about bat detector recorded sound, sound by ear, as well as advice on techniques and methods to reduce or increase the likelihood of recording other sounds. The book concludes with associated appendices, including a ‘Problem Solving Key’ to help those encountering an unfamiliar sound to narrow it down to the likely source. With technology advancing at pace, the technical ability of the analyst is of huge importance. With a wider perspective and more knowledge, those responsible for interpreting field encounters can be more confident when making decisions about sources of sound. Apart from that, ‘knowing stuff’ makes the job far more interesting and gives the bat worker a greater appreciation of the natural world within which they are working.

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.
