Managing Clutter in a High Pulse Rate Echolocation System
Frontiers in Neuroscience, 2018 The use of echolocation for navigating in dense, cluttered environments is a challenge due to the need for rapid sampling of nearby objects in the face of delayed echoes from distant objects.

Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT Biphonation—the simultaneous production of two independent fundamental frequencies within a single vocalization—is a prominent feature of killer whale calls, yet the factors influencing the presence and intensity of heterodyne frequencies, which arise from interactions between these fundamentals, remain poorly understood. We analyzed long‐term

Correlated evolution between body size and echolocation in bats (order Chiroptera)
BMC Ecology and EvolutionBackground 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 ...

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.

Echolocation as an Acoustic Form of Relative Positioning [PDF]
TransNavTo introduce order in the movement of many objects, they need to avoid collisions with their neighbours by knowing their position and reacting to it.

Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT Passive acoustic monitoring (PAM) generates large datasets that are costly to analyze manually, creating the need for accurate automated detection methods. While deep learning (DL) has shown promise for PAM‐related tasks, the transferability of trained models to unseen datasets remains a critical challenge.

Bionic Tactile Skins for Robotics: Fundamentals, Advances, and Future Prospects
SmartSys, Volume 2, Issue 3, September 2026.ABSTRACT Robotic bionic tactile skins (RBTSs), as crucial components of next‐generation robotic systems, have attracted significant attention in recent years. By enabling robots to achieve human‐like tactile perception and interact effectively with their surroundings, RBTSs play an essential role in enhancing robotic intelligence.

Wildlife Biology, Volume 2026, Issue 5, September 2026.Sympatric bat species can co‐exist and avoid interspecific competition via niche differentiation e.g. diet. Detecting dietary differences can be achieved by comparing dietary niches of sympatric and allopatric populations. If dietary overlap is higher in sympatry versus allopatry, co‐occurrence may be altering the dietary niche of the species.

Biotropica, Volume 58, Issue 5, September 2026.ABSTRACT Bats, the second most diverse group of mammals, play essential ecological roles in insect control, pollination, and seed dispersal. In Peru, insectivorous bats remain poorly studied, particularly in high‐elevation rainforest ecosystems of the upper Amazon region.
