Bat echolocation signals based on the time-varying autoregressive method [PDF]

Frontiers in Zoology
Bat echolocation is among the most efficient biological sonar known to human, and is highly valuable for biomimetic research. Most bats produce dynamically changing echolocation signals, which is the key to high task performance.

Correlated evolution between body size and echolocation in bats (order Chiroptera) [PDF]

BMC Ecology and Evolution
Background Body size and echolocation call frequencies are related in bats. However, it is unclear if this allometry applies to the entire clade. Differences have been suggested between nasal and oral emitting bats, as well as between some taxonomic ...

Human-Machine Cooperative Echolocation Using Ultrasound

IEEE Access, 2022
Echolocation has been shown to improve the independence of visually impaired people, and utilizing ultrasound in echolocation offers additional advantages, such as a higher resolution of object sensing and ease of extraction from background sounds ...

Greater Horseshoe Bats Recognize the Sex and Individual Identity of Conspecifics from Their Echolocation Calls

Animals, 2022
The echolocation calls of bats are mainly used for navigation and foraging; however, they may also contain social information about the emitter and facilitate social interactions.

Silence and reduced echolocation during flight are associated with social behaviors in male hoary bats (Lasiurus cinereus)

Scientific Reports, 2021
Bats are renowned for their sophisticated echolocation. However, recent research has indicated that bats may be less reliant on echolocation than has long been assumed.

Correlated evolution of wing morphology and echolocation calls in bats

Frontiers in Ecology and Evolution, 2022
IntroductionFlight and echolocation are two crucial behaviors associated with niche expansion in bats. Previous researches have attempted to explain the interspecific divergence in flight morphology and echolocation vocalizations in some bat groups from ...

Different auditory feedback control for echolocation and communication in horseshoe bats. [PDF]

PLoS ONE, 2013
Auditory feedback from the animal's own voice is essential during bat echolocation: to optimize signal detection, bats continuously adjust various call parameters in response to changing echo signals.

High duty cycle to low duty cycle: echolocation behaviour of the hipposiderid bat Coelops frithii. [PDF]

PLoS ONE, 2013
Laryngeally echolocating bats avoid self-deafening (forward masking) by separating pulse and echo either in time using low duty cycle (LDC) echolocation, or in frequency using high duty cycle (HDC) echolocation. HDC echolocators are specialized to detect
