Global Aerial Sampling of Migratory Insects (IMAGE)
Caption
Fig 1. Global Aerial Sampling of Migratory Insects. It maps the locations and methods used for historical (dashed lines) and recent (solid lines) aerial sampling of high-flying migratory insects across Europe (green), North America (purple), and Asia (orange). The sampling was conducted using various techniques, including tethered balloons (top left) and kites (bottom right), airplanes (bottom left), and high mountain nets (top right).
The inset scatter plot shows the natural log-transformed aerial density (log No./103m3) of all high-flying insects sampled over time (1926-2017). The data points are color-coded by continent, with the overall statistical analysis indicating no significant change in aerial density over the time period shown.
