Abstract:

Soundscape ecology studies sound patterns across different spatial and temporal scales, which reflects coupled natural-human dynamics in a changing landscape. Here, we synthesized a list of peer-reviewed studies on soundscape ecology to summarize the conceptual framework of the field, the methodology used, and acoustic indices developed from these studies. Studies on soundscape ecology are currently focused on the following aspects: (1) acoustic composition of soundscape; (2) acoustic interactions between soundscape components; (3) temporal patterns and spatial variability in the soundscapes; (4) the development of acoustic indices for biodiversity monitoring. We suggest the following as focuses for future studies in soundscape ecology and biodiversity conservation: (1) establishing a systematic acoustic monitoring network and data management platform; (2) developing new methods for data collection and analysis (e.g., recording matrix and machine learning algorithm); and (3) treating soundscape ecology as an important resource for future research and conservation.

Key words: soundscape monitoring, acoustic indices, acoustic niche, biodiversity monitoring, automated acoustic recording
