It’s not black or white - on the range of vision and echolocation in echolocating bats [PDF]

Frontiers in Physiology, 2013
Around 1000 species of bats in the world use echolocation to navigate, orient and detect insect prey. Many of these bats emerge from their roost at dusk and start foraging when there is still light available.

When echolocating bats do not echolocate [PDF]

Communicative & Integrative Biology, 2008
Echolocating bats are known to continuously generate high frequency sonar pulses and listen to the reflecting echoes to localize objects and orient in the environment. However, silent behavior has been reported in a recent paper, which demonstrated that the big brown bat (Eptesicus fuscus) can fly a relative long distant (0.6 to 8 m) without ...

Repeated Observations Suggesting Kleptoparasitism by a Common Bottlenose Dolphin (<i>Tursiops truncatus</i>) on the Great Barrier Reef. [PDF]

Ecol Evol
This study documents the first detailed case of kleptoparasitism in cetaceans, with observations of a Common Bottlenose Dolphin repeatedly pursuing Bigeye Trevally to induce the fish to regurgitate their prey, which is then consumed by the dolphin.

Description of Echolocation Call Parameters for Urban Bats in Vietnam as a Step Towards a More Integrated Acoustic Monitoring of Urban Wildlife in Southeast Asia

Diversity, 2021
This study is the first step towards more systematic monitoring of urban bat fauna in Vietnam and other Southeast Asian countries by collecting bat echolocation call parameters in Ho Chi Minh and Tra Vinh cities.

Driving factors for the evolution of species-specific echolocation call design in new world free-tailed bats (molossidae). [PDF]

PLoS ONE, 2014
Phylogeny, ecology, and sensorial constraints are thought to be the most important factors influencing echolocation call design in bats. The Molossidae is a diverse bat family with a majority of species restricted to tropical and subtropical regions ...

6-hour Training in click-based echolocation changes practice in visual impairment professionals

Frontiers in Rehabilitation Sciences, 2023
Click-based echolocation can support mobility and orientation in people with vision impairments (VI) when used alongside other mobility methods. Only a small number of people with VI use click-based echolocation.

Rhythm Across Species: Situating Human Speech in a Comparative Framework. [PDF]

Ann N Y Acad Sci
We analyzed speech rhythms from 48 human languages using methods drawn from biology and linguistics. Interonset intervals across languages are surprisingly similar, with a median value of 2 seconds., despite substantial differences in linguistic structure and prosody. A comparative rhythm analysis shows that human speech falls within the range reported

Echolocation in humans: an overview [PDF]

WIREs Cognitive Science, 2016
Bats and dolphins are known for their ability to use echolocation. They emit bursts of sounds and listen to the echoes that bounce back to detect the objects in their environment. What is not as well‐known is that some blind people have learned to do the same thing, making mouth clicks, for example, and using the returning echoes from those clicks to ...
