Spatiotemporal patterning of acoustic gaze in echolocating bats navigating gaps in clutter
iScience, 2021 Summary: We challenged four big brown bats to maneuver through abrupt turns in narrow corridors surrounded by dense acoustic clutter. We quantified bats' performance, sonar beam focus, and sensory acquisition rate.

Insects and Survival: A Review of Primary and Secondary Defense Strategies
Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Wingtip folds and ripples on saturniid moths create decoy echoes against bat biosonar
, 2021 Sensory coevolution has equipped certain moth species with passive acoustic defenses to counter predation by echolocating bats.1,2 Some large silkmoths (Saturniidae) possess curved and twisted biosonar decoys at the tip of elongated hindwing tails.3,4 ...

Temporal Feasibility Constraints on Wingbeat‐Call Synchrony in Actively Echolocating Bats
Ecology and Evolution, Volume 16, Issue 5, May 2026.This study addresses a long‐standing question about the temporal correlation between two rhythmic actions during active echolocation: wingbeat and calling. Existing studies show a certain level of synchrony between the two processes; however, they do not consider the underlying drivers.

Mouth-clicks used by blind expert human echolocators - signal description and model based signal synthesis. [PDF]
PLoS Computational Biology, 2017 Echolocation is the ability to use sound-echoes to infer spatial information about the environment. Some blind people have developed extraordinary proficiency in echolocation using mouth-clicks. The first step of human biosonar is the transmission (mouth

Quiet Signals of Burmeister's Porpoises (Phocoena spinipinnis) Recorded in Chile and Peru
Marine Mammal Science, Volume 42, Issue 2, April 2026.ABSTRACT Burmeister's porpoises are cryptic and challenging to detect visually. More information on their acoustic signals could facilitate the use of passive acoustic monitoring (PAM) and help to better understand their ecology. Here, clicks were recorded from two different Burmeister's porpoise populations, one in Chile and the other in Peru, using a

Subsurface Behaviors of Hector's Dolphins Could Increase Their Risk of Bycatch
Conservation LettersHector's dolphins, endemic to New Zealand, suffer from bycatch in fishing gear. Fishing restrictions in inshore areas have reduced bycatch, although dolphins have been recorded outside these areas.
