Correlated evolution between body size and echolocation in bats (order Chiroptera)

open access: yesBMC Ecology and Evolution
Background 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 ...

The connections of the inferior colliculus and the organization of the brainstem auditory system in the greater horseshoe bat (Rhinolophus ferrumequinum) [PDF]

open access: yes, 1981
The connections of the inferior colliculus, the mammalian midbrain auditory center, were determined in the greater horseshoe bat (Rhinolophus ferrumequinum), using the horseradish peroxidase method.

Characterizing the Distribution and Behavior of Sperm Whales, Physeter macrocephalus, Over the Otago Submarine Canyons, New Zealand

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Sperm whales (Physeter macrocephalus) play an important role in marine ecosystems as top predators, nutrient vectors, and indicators of ecosystem health. In Aotearoa New Zealand, sperm whales remain largely understudied other than at Kaikōura, a foraging area for males.

DOLPHIN ECHOLOCATION [PDF]

open access: yesLe Journal de Physique IV, 1992
Latest achievments in understanding of mechanisms underlying dolphin echolocation are discussed. Main attention is drawn to dolphin detection and recognition in different acoustic conditions. Adaptation of echolocation signal parameters to changing ambient noise and reverberation are also considered.

Sensory Compensation in Children Following Vision Loss after Trauma and Disease [PDF]

open access: yes, 2015
Sensory compensation or sensory substitution occurs when a sense organ, such as the eye, is lost due to trauma or disease. Individuals often experience phantom limb sensation or pain but research increasingly points towards some individuals developing a ...

Effects of Recreational Boats on Harbour Porpoise Swimming Speed and Surfacing Interval Investigated by Two Synchronised UAVs

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study examines the impact of speed and proximity of recreational boats on the swimming speed and surfacing interval of one of the most common coastal cetacean species, the harbour porpoise (Phocoena phocoena), using data collected by unmanned aerial vehicles (UAVs) in a key habitat for the vulnerable Belt Sea population.

Echolocation by Quasiparticles

open access: yes, 2009
It is shown that the local density of states (LDOS), measured in an Scanning Tunneling Microscopy (STM) experiment, at a single tip position contains oscillations as a function of Energy, due to quasiparticle interference, which is related to the ...

A tunable microwave absorption metamaterial inspired by moths evading bat detection

open access: yesInfoMat, Volume 8, Issue 3, March 2026.
Electromagnetic radiation in the current environment has become complex and uncontrollable due to the advancement of wireless technology. Inspired by the moth surface cilia to bend and evade bat sonar detection, our work introduces a metamaterial incorporating broadband and tunable microwave absorption properties combined with deep learning algorithms.

From Understory to Canopy: In situ Behavior of Neotropical Forest Katydids in Response to Bat Echolocation Calls

open access: yesFrontiers in Ecology and Evolution, 2018
Predator-prey interactions take place in complex environments, and research on the sensory ecology of predator-detection relies on understanding when, where, and how prey experience and respond to predator cues.

Passive Acoustic Monitoring Reveals New Insights Into the Acoustic Occurrence and Foraging Activity of Hector's Dolphins in Porpoise Bay, New Zealand

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
To effectively mitigate disturbances from human activities on vulnerable dolphin populations, it is crucial to understand fine‐scale variation in habitat use. This study investigated the habitat utilisation of a small subpopulation of Hector's dolphins (Cephalorhynchus hectori) in Porpoise Bay, New Zealand.
