there have been recent advances in our understanding of the phylogeny and ecology of …

The ability to sense and localize sound is so advantageous for survival that it is difficult to
understand the almost 100 million year gap separating the appearance of early tetrapods …

Drones are being increasingly used in innovative ways to enhance environmental research
and conservation. Despite their widespread use for wildlife studies, there are few …

Crocodilians are diving reptiles that can hold their breath under water for long periods of
time and are crepuscular animals with excellent sensory abilities. They comprise a sister …

Hearing, as defined by numerous investigators of vertebrate hearing, involves not only

Modern crocodylians, including Alligator mississippiensis, have a greatly elaborated system
of pneumatic sinuses invading the cranium. These sinuses invade nearly all the bones of the …

The auditory brainstem response (ABR) was recorded in adult budgerigars (Melopsittacus

It is generally argued that distress vocalizations, a common modality for alerting conspecifics
across a wide range of terrestrial vertebrates, share acoustic features that allow …

Turtles, like other amphibious animals, face a trade-off between terrestrial and aquatic
hearing. We used laser vibrometry and auditory brainstem responses to measure their …

Gharials (Gavialis gangeticus) produce a sudden, high amplitude, pulsatile, underwater
sound called a POP. In this study, gharial POPs ranged from 9 to 55 ms, and were clearly …
