Communication is a fundamental sense of the animal world comprising of both the emission and capture of acoustics. Acoustic variables are used in ecology to census organisms (birds, amphibians, mammals, insects, etc.) and to identify signatures of sounds of human activities and ecological communications. A framework for the study and understanding of patch-level acoustic signals from a landscape is presented. This framework includes a) a taxonomy of the biological and physical characteristics of a soundscape, b) an analytical approach to quantify the components of acoustic samples taken from the environment, c) a protocol for measurement of acoustic signals in the environment, d) a cyber-infrastructure necessary to manage numerous acoustic signals sampled from different environments, and f) a terrestrial sensor technology with wireless networks to measure ecological variables to characterize the spatial heterogeneity of landscape in near-real time from various places in a region. The study was conducted at the KBS-LTER. The sites were classified into two main ecosystems: agricultural and forested. Terrestrial habitat sensors with wireless networks were deployed at the study sites to automatically collect and transmit acoustic signals from multiple sensor platforms to remote servers within communication range. Our findings are in three areas: 1) measurement of avian species diversity using acoustic signals, 2) quantification of ecological acoustic variability at different times and in different habitat types, and 3) development of indices relating human and biophysical acoustics.
