Schematic illustration of data acquisition. A Characterization of habitat utilization. Habitat characteristics and posture were recorded in the field/park and are shown in green (diameter, D; orientation, O; flexibility, F). B Leaping performance and posture. Horizontal leaping distance (LD) was recorded in the field/park, time-related performance measures were extracted from camera recordings and an exemplary trunk-to-trunk leap of L. nigrifrons with a leaping distance of 1.5 m is highlighted in violet (take-off-, flight-, and landing-phases in ms). C Acquired morphological variables. Measurements on the bones are highlighted in orange. Anterior view of the left humerus, ulna, radius, femur, and tibia of the specimen S. mystax AMNH 188,178. The numbers in panel C refer to the labelled data points in Fig. 2C. See text for more information
