Integrative Zoology, EarlyView.Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

A biomimetic projector with high subwavelength directivity based on dolphin biosonar
, 2014 Based on computed tomography of a Yangtze finless porpoise's biosonar system, a biomimetic structure was designed to include air cavity, gradient-index material, and steel outer-structure mimicking air sacs, melon, and skull, respectively.

, 2018 Yangtze finless porpoises (Neophocaena asiaeorientalis) are known to use the narrowband signals for echolocation. In this study, a finite-element model was configured based on computed tomography imaging technique and tissue physical properties ...

WAH‐i: Optimising microphone array geometry for customised localisation accuracy
Methods in Ecology and Evolution, EarlyView.Abstract Accurate spatial localisation of free‐flying echolocating bats is foundational for resolving fine‐scale flight and echolocation behaviour, prey interception and spatial decision‐making in natural environments. Acoustic localisation using microphone arrays is widely employed for this purpose, yet array geometries in field studies are typically ...

Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT Most dolphin species produce broadband biosonar clicks for echolocating prey, and whistles and burst‐pulsed calls for communication purposes. Seven dolphin species were previously reported to only produce clicks of a narrowband high‐frequency (NBHF) type, very similar to the clicks produced by porpoises.

Active control of acoustic field-of-view in a biosonar system. [PDF]
PLoS Biology, 2011 Active-sensing systems abound in nature, but little is known about systematic strategies that are used by these systems to scan the environment. Here, we addressed this question by studying echolocating bats, animals that have the ability to point their ...

Following a foraging fish-finder: diel habitat use of Blainville's beaked whales revealed by echolocation. [PDF]
PLoS ONE, 2011 Simultaneous high resolution sampling of predator behavior and habitat characteristics is often difficult to achieve despite its importance in understanding the foraging decisions and habitat use of predators.

ChemCatChem, Volume 18, Issue 15, 14 August 2026.To selectively detect minority sites and measure their catalytic properties is challenging. As the bat uses the echo of insects to locate them in darkness, we here demonstrate that the echo‐signal of small temperature modulations applied to a catalyst can be used to reveal minority sites.

Dynamics of biosonar systems in Horseshoe bats
, 2015 Horseshoe bats have an active ultrasonic sonar system that allows the animals to navigate and hunt prey in structure-rich natural environments. The physical components of this biosonar system contain an unusual dynamics that could play a key role in ...

Analog VLSI Models of Range-Tuned Neurons in the Bat Echolocation System
EURASIP Journal on Advances in Signal Processing, 2003 Bat echolocation is a fascinating topic of research for both neuroscientists and engineers, due to the complex and extremely time-constrained nature of the problem and its potential for application to engineered systems.
