Ontogeny of the hyoid apparatus in Jamaican fruit bats (Chiroptera: Phyllostomidae) in unraveling the evolution of echolocation in bats

How echolocation and flight evolved in modern day bats is a compelling and largely unanswered question in biology. As laryngeal echolocation in bats is typified by a bony connection between the larynx and the auditory bulla via the hyoid apparatus, we developed an evolutionary‐developmental model of the hyoid to test hypotheses regarding the evolution of echolocation in bats. Using computed tomography of pre‐ and postnatal Jamaican fruit bats (Artibeus jamaicensis), we showed that much of the hyoid apparatus was ossified prior to parturition. This includes the stereotypical articulation of the stylohyal bone with the auditory bulla found in laryngeal echolocating bats, where the cranial end of the stylohyal is flattened and wraps around the auditory bulla. Postnatally, thyrohyal ossification coincided with the development of increased echolocation call emission rate and the development of flight. We contend that the stepwise development of the hyoid apparatus of A. jamaicensis presented here serves as a proxy for the series of transitional forms that lead to the modern day hyoid apparatus and its cranial articulation with the auditory bulla in modern day laryngeally echolocating bats.

La variación por edad y el dimorfismo sexual en murciélagos son aspectos frecuentemente estudiados; sin embargo, esta información no está disponible para Platalina genovensium, una especie de murciélago amenazado que habita ecosistemas secos entre Perú y Chile. En este estudio, se presentan los primeros datos sobre su caracterización en clases de edad y un análisis de dimorfismo sexual. Se analizaron 31 especímenes entre juveniles y adultos para evaluar la ontogenia. Luego, usando solo especímenes adultos se evaluó la presencia de dimorfismo sexual mediante análisis estadísticos y multivariados usando una variable externa y 14 cráneo-dentales. Como resultado, se presenta caracterizaciones de los estadíos juvenil (clase I) y adulto (clases IV y V), además del cráneo de un feto. Con respecto al dimorfismo sexual, se encontró que la longitud del antebrazo entre hembras y machos no presenta diferencias estadísticamente soportadas mientras que, a nivel cráneo-dental, el ancho de la rama mandibular fue la principal variable dimórfica. Se sugiere que las diferencias reportadas entre especímenes juveniles y adultos y entre hembras y machos sean entendidas desde una perspectiva evolutiva y de adaptación y no solo ontogenéticamente.

Despite the remarkable morphological modifications that occurred in the thoracic limbs of bats, information about the brachial plexus in this group is still scarce. The present study aimed to describe the origin, structure, and distribution of these peripheral nerves in four Phyllostomidae species. Both antimeres of six Artibeus lituratus, five Desmodus rotundus, seven Glossophaga soricina, and five Phyllostomus hastatus—all adult males from the Adriano Lúcio Peracchi Collection (UFRRJ)—were dissected. After complete exposure of the structure, we found that the brachial plexus of D. rotundus and P. hastatus is formed by the same roots (C5–T1), whereas the fourth cervical spinal nerve and the second thoracic spinal nerve are present in G. soricina (C4–T1) and A. lituratus (C5–T2), respectively. There was intraspecific variation and asymmetry in the origin of the structure and the combinations of nerve segments forming terminal branches. The distribution to the target muscles and patagium, however, was not subject to significant variation in our sample. Data presented here support the presence of two prevailing conditions in distribution of nerves to the bat muscles, and the innervation of the membranes seems to be explained by embryogenesis. Although the brachial plexus in phyllostomid bats is similar to that of other terrestrial Laurasiatheria, aspects identified in these bats, apparently unique to Chiroptera, may be related to anatomical changes in the thoracic limbs functionally linked to flight.
