Hammer-headed bat movement behavior and habitat selection

Background: Animals with key ecological roles, such as seed-dispersing fruit bats, rely to varying degrees on habitat structure to indicate the locations of rewards and risks.
Methods: To understand how variation in vegetation structure influences fruit bat selection, we related movement steps of hammer-headed bats (Hypsignathus monstrosus) to attributes of canopy height, vertical and horizontal structure, and habitat type in a mature rainforest of southern Cameroon. Vegetation structural metrics were measured with UAV-LiDAR at 10 m resolution for a 25 km2 study area. Because bats frequently moved outside the study area, we also characterized vegetation height and horizontal complexity over the full extent of bat movement trajectories by upscaling UAV-LiDAR measurements using spaceborne remote sensing, including GEDI LiDAR data.
Results: At the site level, hammer-headed bats preferred areas of intermediate canopy height close to large canopy gaps (≥500 m). Individual bats varied in sel..., , , # Habitat selection of hammer-headed bats
