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.

Bat Tongues and Foraging: Linking Morphology to Hunting Strategies
Integrative Zoology, EarlyView.We linked the bat tongue's mediodorsal lobe (MDL), a muscular prominence, to foraging strategies. Aerial hawkers exhibit tall MDLs and prominent forward‐pointing papillae. The MDL may function as a barrier or filter, preventing unintentional ingestion of non‐food material, aiding in prey handling, and controlling food access during fast flight ...

Consistent Choice of Prey Source Habitat Across Diverse Landscapes by a Selective Insectivorous Bat
Integrative Zoology, EarlyView.After analyzing the diet of the greater horseshoe bats in three distinct colonies, we identified significant spatial and temporal differences, particularly noting a stronger reliance on riparian habitats in Mediterranean areas. The species exhibits great ecological adaptability with strong plasticity in prey source habitats, shifting preferences among ...

The Development of a Single Frequency Place in the Mammalian Cochlea: The Cochlear Resonance in the Mustached Bat Pteronotus parnellii [PDF]
, 2003 Cochlear microphonic potentials (CMs) were recorded from the sharply tuned, strongly resonant auditory foveae of 1- to 5-week-old mustached bats that were anesthetized with Rompun and Ketavet.

BSG‐BATS: An open‐source data annotation portal and classifier for European bat vocalizations
Methods in Ecology and Evolution, EarlyView.Abstract Bats are ecologically important mammals whose monitoring increasingly relies on acoustic data. However, many tools for bat call identification remain subscription‐based, closed‐source, region‐specific or limited in scalability, creating barriers to global data integration and method development.

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.

ESPERDYNE: A dual‐band heterodyne monitor and ultrasound recorder for bioacoustic field surveys
Methods in Ecology and Evolution, EarlyView.Abstract Background. Ultrasonic monitoring is essential for ecological studies of bats and other animals, yet high‐performance field devices remain prohibitively expensive and inaccessible—particularly in biodiversity‐rich regions with limited research infrastructure.

Le 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.
