| dc.description | The Osseous structure of the auditory bullae of the desert kangaroo rat, Dipodomys deserti, has been studied. The most significant modifications of this structure are the relatively free suspension of the bony labyrinth, the inflated character of the mastoid and tympanic bones, the enlarged tympanic membrane and elongated manubrium and an intrincate articulation of the malleus and incuso. Evidence based upon habitat selection and the degree of specialization of this species would seem to indicate that these features have accompanied other adaptations as an important supplement. It seems likely that auditory perception has been an adaptation of selective value in the evolution of Dipodomys deserti. | en-US |
| dc.description | Se estudia la estructura ósea de la bula auditiva de la rata saltadora del desierto, Dipodomys deserti. Las modificaciones más importantes de esta estructura son la suspensión relativamente libre del laberinto óseo, la inflación marcada de los huesos mastoide y timpánico, la membrana timpánica agrandada con alargamiento proporcional del manubrio, y la articulación interdigitada del martillo y el yunque. La selección de habitat y el grado de especialización de esta especie parecen indicar que aquellos caracteres han acompañado a otras adaptaciones como suplemento importante. Parece probable que la percepción auditiva muy aguda ha sido una adaptación de valor selectivo en la evolución de Dipodomys deserti. | es-ES |
