Fig. 3From: Scheimpflug lidar range profiling of bee activity patterns and spatial distributionsTime-range map of insect activity during the second measurement day. Insect counts per minute and 1 m of transect evaluated in 15 min, 2 m bins. By the beehives at 180 m, the activity is 30 times higher than in the surrounding area. More activity is recorded closer to the lidar, since the sensitivity decreases with range. The maximum activity is indicated by an arrow at 14:45Back to article page
