Automated acoustic monitoring
Acoustic emisions are crucial in the live of grasshoppers, as the females choose their mates based on the male song. Researchers use the songs to recognize the different species. A rather new development is the automated monitoring of Orthoptera. By using recorders in the field, this yields new insights in the distribution of biodiversity patterns and enables new ways of detecting changes in the communities. In this study experiments on acoustic monitoring on Hymettos mountain (Greece) have been performed and recommendations are done for further studies.
