The sounds produced by geophonic, biophonic and technophonic sources are relevant to the function of natural and human modified ecosystems. Passive recording is one of the most non-invasive technologies as its use avoids human intrusion during acoustic surveys and facilitates the accumulation of huge amounts of acoustical data.
For the first time, this book collates and reviews the science behind ecoaucostics; illustrating the principles, methods and applications of this exciting new field. Topics covered in this comprehensive volume include;
- the assessment of biodiversity based on sounds emanating from a variety of environments
- the best technologies and methods necessary to investigate environmental sounds
- implications for climate change and urban systems
- the relationship between landscape ecology and ecoacoustics
- the conservation of soundscapes and the social value of ecoacoustics
- areas of potential future research.
An invaluable resource for scholars, researchers and students, Ecoacoustics: The Ecological Role of Sounds provides an unrivalled set of ideas, tools and references based on the current state of the field.
EDITED BY
ALMO FARINA is Professor of Ecology, Department of Pure and Applied Sciences, Urbino University, Italy. He is interested in developing theories in landscape ecology and ecoacoustics. He has published more than 270 reports, articles and books on zoology, eco-ethology, bird community ecology, landscape ecology, landscape changes, rural landscape modification, eco-semiotics, code biology, ecoacoustics, soundscape ecology, and ecological theories.
STUART H. GAGE is Professor Emeritus, Michigan State University, East Lansing, Michigan, USA. Stuart retired after about 30 years as Professor of Entomology. He received the University Distinguished Faculty Award and the University Outreach and Engagement Campus Fellow at Michigan State University. Stuart continues as Director of the Remote Environmental Assessment Laboratory. His current research focuses on application of ecological sensors, analysis of acoustic sensor observations and cyber infrastructure and he collaborates with colleagues in all realms of acoustics. The study of ecological acoustics has enabled Stuart to record the soundscape in many places using automated sensors. Many of these recordings are analyzed, stored, and are publicly accessible in a digital acoustics library (http://www.real.msu.edu).
