Advances in bioacoustic monitoring and animal welfare assessment in zoos
Background & Aims:Zoos are increasingly vital for education,conservation,and scientific research which focuses on animal welfare.The acoustic environment significantly affects the well-being of captive animals and associated people.However,the ability to monitor and manage the acoustic environment in zoos remains poorly studied.We review the advances of acoustic monitoring and animal welfare assessment in zoos and identify future research directions.Progress:The application of passive and active acoustic monitoring technologies in zoos provides insight into animal behavior and welfare.Additionally,the use of machine learning for the analysis of acoustic data offers a non-invasive method to assess animal welfare.Perspective:There are opportunities for developing acoustic monitoring devices and intelligent recognition and analysis technologies for acoustic data.Doing so will help establish a comprehensive evaluation system and standards for acoustic environment quality while enhancing educational efforts related to acoustic welfare in zoos.The integration of disciplinary theories and technical methods enables researchers and management to provide systematic solutions for captive animal reproduction,health,conservation,and acoustic environment management in zoos.
