EDITED BYALMO 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).
