From: Correlated evolution between body size and echolocation in bats (order Chiroptera)
Regression fits according to the best PGLS models between body mass and peak frequency (a), bandwidth (b), and call duration (c). This model includes a distinction between nasal (blue triangles) and oral (black dots) emitting bats for 314 bat species. Pictures of a Pipistrellus pipistrellus and a Rhinolophus hipposideros has been included as examples of oral and nasal emitting bats respectively (MNCN-M1060 and MNCN-M357 specimens from Natural Sciences History Museum of Madrid, Spain). (PF) peak frequency, (BW) bandwidth and (CD) have been highlighted on a spectrogram of a Pipistrellus pipistrellus above their respective panel (bats and spectrogram images produced by M.G.C). This figure with the five major taxonomic families in the dataset distinguished can be seen in Supplementary material Fig. 1
