eLife, 2015 Perceptual abilities of animals, like echolocating bats, are difficult to study because they challenge our understanding of non-visual senses. We used novel acoustic tomography to convert echoes into visual representations and compare these cues to ...

Dolphins can maintain vigilant behavior through echolocation for 15 days without interruption or cognitive impairment. [PDF]
PLoS ONE, 2012 In dolphins, natural selection has developed unihemispheric sleep where alternating hemispheres of their brain stay awake. This allows dolphins to maintain consciousness in response to respiratory demands of the ocean. Unihemispheric sleep may also allow

Female‐Biased Sexual Size Dimorphism and Its Potential Causes in Hairy‐Winged Bats
Integrative Zoology, EarlyView.Based on the integration of molecular genetics, traditional and geometric morphology, and acoustic characteristics of hairy‐winged bats (a species that was historically misclassified into two species due to extreme craniodental divergence between the sexes) in multiple regions of China, we quantified the sexual size dimorphism (SSD) between males and ...

Pregnancy-related sensory deficits might impair foraging in echolocating bats
BMC Biology, 2023 Background Reproduction entails substantial demands throughout its distinct stages. The mammalian gestation period imposes various energetic costs and movement deficits, but its effects on the sensory system are poorly understood.

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.

Integrative Zoology, EarlyView.Typhlomys daloushanensis, a poorly known and unique echolocating rodent. Using a captive breeding colony, we quantify key reproductive parameters, including gestation length, litter size, interbirth interval, and development to maturity, and evaluate these in relation to mating system structure.

Bat echolocation signals based on the time-varying autoregressive method
Frontiers in ZoologyBat 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.

Ranging in human sonar: effects of additional early reflections and exploratory head movements.
PLoS ONE, 2014 Many blind people rely on echoes from self-produced sounds to assess their environment. It has been shown that human subjects can use echolocation for directional localization and orientation in a room, but echo-acoustic distance perception--e.g.

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 ...

BiomimeticsIn this paper, we introduce SonoNERFs, a novel approach that adapts Neural Radiance Fields (NeRFs) to model and understand the echolocation process in bats, focusing on the challenges posed by acoustic data interpretation without phase information ...
