Predicting ecology and hearing sensitivities in Parapontoporia-An extinct long-snouted dolphin. [PDF]
Anat Rec (Hoboken)Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Hearing sensation levels of emitted biosonar clicks in an echolocating Atlantic bottlenose dolphin. [PDF]
PLoS ONE, 2012 Emitted biosonar clicks and auditory evoked potential (AEP) responses triggered by the clicks were synchronously recorded during echolocation in an Atlantic bottlenose dolphin (Tursiops truncatus) trained to wear suction-cup EEG electrodes and to detect ...

Noseleaf dynamics during pulse emission in horseshoe bats. [PDF]
PLoS ONE, 2012 Horseshoe bats emit their biosonar pulses nasally and diffract the outgoing ultrasonic waves by conspicuous structures that surrounded the nostrils. Here, we report quantitative experimental data on the motion of a prominent component of these structures,

The long-range echo scene of the sperm whale biosonar. [PDF]
Biol Lett, 2020 Sperm whales use their gigantic nose to produce the most powerful sounds in the animal kingdom, presumably to echolocate deep-sea prey at long ranges and possibly to debilitate prey.

Vocalization Characteristics of the Indo-Pacific Humpback Dolphins (<i>Sousa chinensis</i>) in Xiamen Bay With Insights on Regional Differences. [PDF]
Ecol EvolThe Indo‐Pacific humpback dolphin population in Xiamen Bay was divided into two geographically separated but socially associated communities inhabiting the West and East sub‐regions. Based on 3 years of boat‐based surveys, this study established baseline acoustic characteristics and investigated whether vocal patterns varied with habitat conditions ...

Functional Analyses of Peripheral Auditory System Adaptations for Echolocation in Air vs. Water
Frontiers in Ecology and Evolution, 2021 The similarity of acoustic tasks performed by odontocete (toothed whale) and microchiropteran (insectivorous bat) biosonar suggests they may have common ultrasonic signal reception and processing mechanisms.

Oilbirds produce echolocation signals beyond their best hearing range and adjust signal design to natural light conditions [PDF]
Royal Society Open Science, 2017 Oilbirds are active at night, foraging for fruits using keen olfaction and extremely light-sensitive eyes, and echolocate as they leave and return to their cavernous roosts. We recorded the echolocation behaviour of wild oilbirds using a multi-microphone
