Testing hypotheses of bat baculum function with 3D models derived from microCT
Original language description
The baculum (os penis) has been extensively studied as a taxon-specific character in bats and other mammals but its mechanical function is still unclear. There is a wide consensus in the literature that the baculum is probably a sexually selected character. Using a novel approach combining postmortem manipulation and three-dimensional (3D) imaging, we tested two functional hypotheses in the common noctule bat Nyctalus noctula, the common pipistrelle Pipistrellus pipistrellus, and Nathusius' pipistrellePipistrellus nathusii: (i) whether the baculum can protect the distal urethra and urethral opening from compression during erection and copulation; and (ii) whether the baculum and corpora cavernosa form a functional unit to support both the penile shaftand the more distal glans tip. In freshly dead or frozen and thawed bats, we compared flaccid penises with artificially erect' penises that were inflated with 10% formalin. Penises were stained with alcoholic iodine and imaged with a lab
