The article "Monitoring Aerial Insect Biodiversity: A Radar Perspective" by Silke Bauer, Elske K. Tielens, and Birgen Haest reviews the use of radar technology in monitoring aerial insect biodiversity. Radars are powerful remote-sensing tools that can provide detailed information on the intensity, timing, altitude, and spatial scale of aerial movements, making them particularly suitable for monitoring insects and their movements. The authors discuss how radar-derived measures can contribute to essential biodiversity variables (EBVs) such as species population, species traits, community composition, and ecosystem function. They highlight the advantages of radar-based approaches, including their long-term and regional-to-large-scale deployment, and the potential for integrating data from different radar systems and other monitoring sources. The article also outlines ongoing and future methodological, analytical, and technological advancements that will expand the use of radar for insect biodiversity monitoring. Despite the challenges in species identification, the authors argue that radar can be a valuable asset in the biodiversity monitoring toolbox, with the potential to provide unique insights into insect movements and their ecological impacts.The article "Monitoring Aerial Insect Biodiversity: A Radar Perspective" by Silke Bauer, Elske K.
