Control of echolocation pulses by neurons of the nucleus ambiguus in the rufous horseshoe bat, Rhinolophus rouxi [PDF]

, 1986
1. Horseradish peroxidase was applied by iontophoretic injections to physiologically identified regions of the laryngeal motor nucleus, the nucleus ambiguus in the CF/FM batRhinolophus rouxi. 2.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

SonoNERFs: Neural Radiance Fields Applied to Biological Echolocation Systems Allow 3D Scene Reconstruction through Perceptual Prediction

Biomimetics
In 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 ...

In situ novel environment assay reveals acoustic exploration as a repeatable behavioral response in migratory bats

Scientific Reports, 2021
Integrating information on species-specific sensory perception with spatial activity provides a high-resolution understanding of how animals explore environments, yet frequently used exploration assays commonly ignore sensory acquisition as a measure for

Neural control of vocalization in bats: mapping of brainstem areas with electrical microstimulation eliciting species-specific echolocation calls in the rufous horseshoe bat [PDF]

, 1990
1. The functional role of brainstem structures in the emission of echolocation calls was investigated in the rufous horseshoe bat, Rhinolophus rouxi, with electrical low-current microstimulation procedures. 2.

Ecoacoustics for context‐rich direct and indirect trophic interaction data and ecological network construction

Methods in Ecology and Evolution, EarlyView.
Abstract Understanding species interactions is critical for ecology and conservation, yet conventional network construction methods often lack spatiotemporal resolution and important contextual information. The growing field of ecoacoustics enables remote sensing across large spatiotemporal scales and the monitoring of otherwise cryptic communities ...

Habitat use and diel activity of insectivorous bats across land‐cover types on an Afrotropical oceanic island

Conservation Science and Practice, EarlyView.
Using acoustic surveys, we investigated habitat use and diel activity patterns of insectivorous bats across the main land‐use types of the endemic‐rich Príncipe Island, in Central West Africa. We sampled bat activity at 48 sites spanning old‐growth forests, secondary regrowth forests, shaded cocoa plantations, and horticultural areas.

Insights into foraging behavior from multi-day sound recording tags on goose-beaked whales (Ziphius cavirostris) in the Southern California Bight

Frontiers in Marine Science
Goose-beaked whales (Ziphius cavirostris) are deep-diving cetaceans known for their elusive nature and specialized foraging behavior. In 2019 and 2020, six telemetry tags were deployed on these whales in Southern California, resulting in 395 h of ...

The jamming avoidance response in echolocating bats

Communicative & Integrative Biology, 2019
Bats face many sources of acoustic interference in their natural environments, including other bats and potential prey items that affect their ability to interpret the returning echoes of their biosonar signals.

'Compromise' in Echolocation Calls between Different Colonies of the Intermediate Leaf-Nosed Bat (Hipposideros larvatus). [PDF]

PLoS ONE, 2016
Each animal population has its own acoustic signature which facilitates identification, communication and reproduction. The sonar signals of bats can convey social information, such as species identity and contextual information.
