Analytical approaches for evaluating passive acoustic monitoring data: A case study of avian vocalizations
Abstract The interface between field biology and technology is energizing the collection of vast quantities of environmental data. Passive acoustic monitoring, the use of unattended recording devices to capture environmental sound, is an example where technological advances have facilitated an influ...
