This book was released on 2017 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Time of peak bat activity during the night differs among bat species. Foraging strategies may differ among species due to prey availability, habitat availability, and/or interactions between species. Habitat availability is altered in urban areas, which may affect insect prey availability and interspecies interactions. Monitoring changes in bat diversity and behavior associated with habitat conversion is important, but some traditional bat monitoring methods may not be appropriate for all study sites. Acoustic monitoring techniques, including mobile monitoring using driving transects, may be good alternatives to study nightly activity in urban bat populations. Acoustic monitoring is an important component of many monitoring programs including the North American Bat Monitoring Program (NABat). Driving transects that are approximately 25 to 48 kilometers long within 100 km2 grid cells are used by NABat, but choosing appropriate transect routes can be difficult in urban areas. Shorter transects could be used to alleviate sampling issues, but a modified protocol may be less effective at sampling some bat species. My objectives were to use mobile acoustic monitoring to determine when bat species are active in a single night in urban and non-urban sites, if nightly bat activity patterns in urban sites differ from nightly bat activity patterns in non-urban sites, and whether sampling using a modified mobile acoustic monitoring protocol with reduced transect lengths is effective compared to the standardized NABat protocol. I recorded bat echolocation calls using Anabat acoustic detectors while driving transects through the night at five sites (three "urban" and two "non-urban") located in the Piedmont region of north-central North Carolina from May through August 2016. Transects were driven three times per night in each site starting 45 minutes, 180 minutes, and 300 minutes after sunset using a modified NABat protocol with 6 "short" transects (about 3.2 km long each). An additional "long" transect (about 25 km long, using NABat protocol) was sampled in 4 sites (two of the urban sites and both non-urban sites) starting 45 minutes after sunset. Recorded echolocation call sequences were analyzed manually using AnalookW and automatically using Bat Call Identification and Echoclass software. Total bat activity and Lasiurus borealis activity was decreased later in the night in urban sites. There were also fewer Eptesicus fuscus, Lasionycteris noctivagans, and Nycticeius humeralis calls on the latest time period. There were more E. fuscus, L. noctivagans, and Tadarida brasiliensis calls and fewer L. borealis, N. humeralis, and Perimyotis subflavus calls in urban sites than non-urban sites. Fewer short transects were needed to match the detection probability on long transects for E. fuscus, L. borealis, and P. subflavus, while more short transects were needed for L. noctivagans, N. humeralis, and T. brasiliensis. These results suggest that bats in urban areas partition time differently, which is important to consider as urbanization impacts bat populations. They also suggest that short transects can be used effectively for NABat sampling in urban areas."--Abstract from author supplied metadata.

Available in PDF, EPUB and Kindle. Book excerpt: Acoustic monitoring for bats along driving transects typically involves recording call sequences (bat passes) continuously while driving. While this offers benefits over other survey techniques, it also poses challenges, including background noise on recordings. An alternative approach that may rectify this involves conducting sampling at discrete points along each transect instead. We compared these methods using the same bat detector, along with an additional higher sensitivity detector to determine which method yields the highest amount and quality of data per unit of time. Results from 26 18 km transects, each sampled continuously and at 10 point count sites indicate that, with a lower sensitivity detector, the two methods yield a similar number of passes per minute, percent of passes identified to species, and species documented. The higher sensitivity bat detector could not be used for continuous sampling due to background noise. However, at point count sites, the higher sensitivity detector recorded 17 times more passes per minute, 44 times more passes identified to species, and documented nearly twice as many species. Thus, while both sampling designs appear comparable, for most applications, a higher sensitivity detector trumps sampling design.

Download or read book 50 Years of Bat Research written by Burton K. Lim and published by Springer Nature. This book was released on 2021-01-23 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 1,400 species, bats are an incredibly diverse and successful group of mammals that can serve as model systems for many unique evolutionary adaptations. Flight has allowed them to master the sky, while echolocation enables them to navigate in the dark. Being small, secretive, nocturnal creatures has made bats a challenge to study, but over the past 50 years, innovative research has made it possible to dispel some of the mystery and myth surrounding them to give us a better understanding of the role these animals play in the ecosystem. The structure of the book is based on several broad themes across the biological sciences, including the evolution of bats, their ecology and behavior, and conservation of biodiversity. Within these themes are more specific topics on important aspects of bat research, such as morphology, molecular biology, echolocation, taxonomy, systematics, threats to bats, social structure, reproduction, movements, and feeding strategies. Given its scope, the book will appeal to the wider scientific community, environmental organizations, and government policymakers who are interested in the interdisciplinary aspects of biology and nature.

Download or read book Bat Bioacoustics written by M. Brock Fenton and published by Springer. This book was released on 2016-06-02 with total page 318 pages. Available in PDF, EPUB and Kindle. 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 Biodiversity Monitoring and Conservation written by Ben Collen and published by John Wiley & Sons. This book was released on 2013-02-14 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the impacts of anthropogenic activities increase in both magnitude and extent, biodiversity is coming under increasing pressure. Scientists and policy makers are frequently hampered by a lack of information on biological systems, particularly information relating to long-term trends. Such information is crucial to developing an understanding as to how biodiversity may respond to global environmental change. Knowledge gaps make it very difficult to develop effective policies and legislation to reduce and reverse biodiversity loss. This book explores the gap between global commitments to biodiversity conservation, and local action to track biodiversity change and implement conservation action. High profile international political commitments to improve biodiversity conservation, such as the targets set by the Convention on Biological Diversity, require innovative and rapid responses from both science and policy. This multi-disciplinary perspective highlights barriers to conservation and offers novel solutions to evaluating trends in biodiversity at multiple scales.

Available in PDF, EPUB and Kindle. Book excerpt: No other method of bat detection is as popular and widespread in the context of environmental assessment and voluntary work as acoustic detection; its increasing use has driven the development of a large number of sophisticated devices and analytical methods. Acoustic detection has become a standard method for establishing the presence of bats, carrying out species identification and monitoring levels of activity. The resolution, accuracy and scale with which these tasks can be carried out has risen dramatically with the availability of automated real-time recording. Anyone who is concerned with acoustic recording will readily acknowledge that, despite the euphoria, there are unresolved questions concerning the possibilities and limits of acoustic detection. Clear definitions of how to handle the data are usually missing, for example there are no clearly described activity indices. In response to the limited information on the underlying science of acoustic detection, the authors offer this handbook. They provide an in-depth understanding of acoustic detection principles, study planning, data handling, properties of bat calls, manual identification of species, automatic species recognition, analysis of results, quality assurance and the background physics of sound.

Download or read book Renewable Energy and Wildlife Conservation written by Christopher E. Moorman and published by JHU Press. This book was released on 2019-09-10 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brings together disparate conversations about wildlife conservation and renewable energy, suggesting ways these two critical fields can work hand in hand. Renewable energy is often termed simply "green energy," but its effects on wildlife and other forms of biodiversity can be quite complex. While capturing renewable resources like wind, solar, and energy from biomass can require more land than fossil fuel production, potentially displacing wildlife habitat, renewable energy infrastructure can also create habitat and promote species health when thoughtfully implemented. The authors of Renewable Energy and Wildlife Conservation argue that in order to achieve a balanced plan for addressing these two crucially important sustainability issues, our actions at the nexus of these fields must be directed by current scientific information related to the ecological effects of renewable energy production. Synthesizing an extensive, rapidly growing base of research and insights from practitioners into a single, comprehensive resource, contributors to this volume • describe processes to generate renewable energy, focusing on the Big Four renewables—wind, bioenergy, solar energy, and hydroelectric power • review the documented effects of renewable energy production on wildlife and wildlife habitats • consider current and future policy directives, suggesting ways industrial-scale renewables production can be developed to minimize harm to wildlife populations • explain recent advances in renewable power technologies • identify urgent research needs at the intersection of renewables and wildlife conservation Relevant to policy makers and industry professionals—many of whom believe renewables are the best path forward as the world seeks to meet its expanding energy needs—and wildlife conservationists—many of whom are alarmed at the rate of renewables-related habitat conversion—this detailed book culminates with a chapter underscoring emerging opportunities in renewable energy ecology.
