Download or read book Do Bats Use Olfactory Cues to Find Roosts written by Bridget Kay Gladden Brown and published by . This book was released on 2020 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding how bats select roosts is crucial to their management and conservation. One way that bats can locate new roosts is by using cues from conspecifics. Research on this use of social information has mostly focused on conspecific calls. In many species, bats will move toward conspecific echolocation and social calls, which can help bats find new roosts faster. However, many roosts also have olfactory cues from guano and urine. Bat conservationists have long debated whether guano and urine can be used to attract bats to new roosts. If chemical cues can act as an effective bat lure, this would aid in efforts to exclude bats from buildings and attract them to artificial roosts in protected areas like state parks or wildlife preserves. In my thesis, I ask if bats use olfactory cues from guano and urine to locate potential roosts. In Chapter 1, I summarized research to date on the topic of the use of olfaction by roost-searching bats and I discuss reasons that bats might, or might not, use scent to locate roosts. From this research, results are consistent with the hypothesis that guano and urine are not strong enough lures to attract bats to new roosts. In Chapter 2, I describe experiments with three bat species given choices between a roosting area treated with guano and urine and an untreated control roosting area in captivity and in the field. This chapter describes experiments done by me (field experiments 1 and 2, captive experiments 4 and 6) and by other researchers (captive experiments 1, 2, 3, and 5). In field experiment 1 and 2, I used acoustic-based bat detectors to measure bat visits and nearby bat activity at paired treated and untreated artificial roosts for one-week deployments at 16 sites in Panama (13 weeks) targeting velvety free-tailed bats (Molossus molossus) and at 7 sites in Ohio (17 weeks) targeting big brown bats (Eptesicus fuscus). Only one visit was detected, and the activity did not show an effect of the treatment. In the captive experiments, I tested vampire bats (Desmodus rotundus) using paired roost tubes (n=5 bats), using surfaces with different improved test procedures (n=20, n=22, n=33), and using a y-maze that compared their scent response to that of sound cues or the combination of sound and scent cues. I also tested captive velvety free-tailed bats instead (n=18). The overall effect size of scent cues on roost selection by captive bats was near zero. Ultimately, this indicates that guano and urine are not a strong enough lure to consistently draw bats into a roosting area.

Download or read book Social Functions of Bat Vocalizations written by Mirjam Knörnschild and published by Frontiers Media SA. This book was released on 2023-08-11 with total page 180 pages. 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 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 Animal Movement Across Scales written by Lars-Anders Hansson and published by Oxford University Press. This book was released on 2014 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study takes a broad and timely approach to animal movement across both temporal and spatial scales. Movement and migration on land, in the air, and in water are pervading features of animal life-from the smallest protozoans to the largest whales - and can extend from millimetres to global scale. Research into animal movement ecology is now entering a new era with the development of novel molecular, electronic, and technical methods that make it possible to analyse the movements of individual animals under complex environmental conditions that determine the evolution of movement habits.
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.
Download or read book A Bat Man in the Tropics written by Theodore Fleming and published by Univ of California Press. This book was released on 2003-11-10 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The euphoria of discovery is the only motivation many scientists need for studying nature and its secrets. Yet euphoria is rarely expressed in scientific publications. This book, a personal account of more than thirty years of fieldwork by one of the world’s leading bat biologists, wonderfully conveys the thrill of scientific discovery. Theodore Fleming’s work to document the lives and ecological importance of plant-visiting bats has taken him to the tropical forests of Panama, Costa Rica, and Australia, and to the lush Sonoran Desert of northwest Mexico and Arizona. This book tells the story of his fascinating career and recounts his many adventures in the field. Fleming weaves autobiographical reflections together with information on the natural history and ecology of bats and describes many other animals and plants he has encountered. His book details the stresses and rewards of life in scientific field camps, gives portraits of prominent biologists such as Dan Janzen and Peter Raven, and traces the development of modern tropical biology. A witness to the destruction and development of many of the forests he has visited throughout his career, Fleming makes a passionate plea for the conservation of these wild places.

Download or read book Sexual Selection written by Regina H. Macedo and published by Academic Press. This book was released on 2013-09-25 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sexual Selection: Perspectives and Models from the Neotropics presents new sexual selection research based upon neotropical species. As neotropical regions are destroyed at an alarming rate, with an estimated 140 species of rainforest plants and animals going extinct every day, it is important to bring neotropical research to the fore now. Sexual selection occurs when the male or female of a species is attracted by certain characteristics such as form, color or behavior. When those features lead to a greater probability of successful mating, they become more prominent in the species. Although most theoretical concepts concerning sexual selection and reproductive strategies are based upon North American and European fauna, the Neotropical region encompasses much more biodiversity, with as many as 15,000 plant and animal species in a single acre of rain forest. This book illustrates concepts in sexual selection through themes ranging from female cryptic choice in insects, sexual conflict in fish, interaction between sexual selection and the immune system, nuptial gifts, visual and acoustic sexual signaling, parental investment, to alternative mating strategies, among others. These approaches distinguish Sexual Selection from current publications in sexual selection, mainly because of the latitudinal and taxonomic focus, so that readers will be introduced to systems mostly unknown outside the tropics, several of which bring into question some well-established patterns for temperate regions. Synthesizes sexual selection research on species from the Neotropics Combines different perspectives and levels of analysis using a broad taxonomic basis, introducing readers to systems mostly unknown outside the tropics and bringing into question well-established patterns for temperate regions Includes contributions exploring concepts and theory as well as discussions on a variety of Neotropical vertebrates and invertebrates, such as insects, fish, arthropods and birds
Download or read book Assessing the Use of Social Calls to Attract Bats to Artificial Roost Sites written by Alyson Frances Brokaw and published by . This book was released on 2015 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many conservation strategies for bats focus on supporting or enhancing their roosting and foraging needs. With increasing urbanization and loss of natural habitat, many species have adapted to roost in anthropogenic structures, resulting in increased human-wildlife conflict. Bat boxes can provide alternate housing for bats displaced due to exclusions from anthropogenic structures or loss of natural roosts. Researchers and conservationists have begun to investigate the variety of cues bats use to locate and select possible roost locations, such as visual, olfactory or auditory cues. In this study, I describe the call structure of social calls emitted by Yuma myotis (Myotis yumanensis) at roost sites. I investigated if free-ranging Yuma myotis react to social calls of conspecifics and other bat species at roost sites. I also evaluated the effects of age, sex and reproductive status on behavioral responses to social calls. In the summers of 2013 and 2014, I recorded calls from Yuma myotis using bat detectors mounted outside of roost exits. The recorded social calls divided into two distinct types that I could isolate and identify. Type 1 calls consist of a single frequency modulation (FM) syllable, while Type 2 calls consist of a descending FM sweep, finishing on a hook-shaped component. I broadcast social call and echolocation calls of Yuma myotis and Mexican free-tailed bats (Tadarida brasiliensis mexicana) from newly erected artificial roost sites. Bat activity was significantly higher during playbacks of myotis social calls compared to other playback treatments or silent control nights. Additionally, bat activity remained elevated after playback treatments, indicating a latent effect of playbacks at roosting sites. To test individual responses, bats were placed in a field flight tent and exposed to the same broadcast calls used in the field experiment. Individuals in a flight cage displayed no significant response to social calls, regardless of age, sex or reproductive status. This study provides the first description of social calls in a North American myotis species and suggests that understanding the social relationships of bats at roosting and foraging sites may be useful for informing conservation and management decisions.
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 273 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 Behavioural Responses to a Changing World written by Ulrika Candolin and published by OUP Oxford. This book was released on 2012-06-14 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human-induced environmental change currently represents the single greatest threat to global biodiversity. Species are typically adapted to the local environmental conditions in which they have evolved. Changes in environmental conditions initially influence behaviour, which in turn affects species interactions, population dynamics, evolutionary processes and, ultimately, biodiversity. How animals respond to changed conditions, and how this influences population viability, is an area of growing research interest. Yet, despite the vital links between environmental change, behaviour, and population dynamics, surprisingly little has been done to bridge these areas of research. Behavioural Responses to a Changing World is the first book of its kind devoted to understanding behavioural responses to environmental change. The volume is comprehensive in scope, discussing impacts on both the mechanisms underlying behavioural processes, as well as the longer-term ecological and evolutionary consequences. Drawing on international experts from across the globe, the book covers topics as diverse as endocrine disruption, learning, reproduction, migration, species interactions, and evolutionary rescue.
