Bats expand their vocal range by recruiting different laryngeal structures for echolocation and social communication.

Autor: Jonas Håkansson, Cathrine Mikkelsen, Lasse Jakobsen, Coen P H Elemans

Publikováno v: PLoS Biology, Vol 20, Iss 11, p e3001881 (2022)

Echolocating bats produce very diverse vocal signals for echolocation and social communication that span an impressive frequency range of 1 to 120 kHz or 7 octaves. This tremendous vocal range is unparalleled in mammalian sound production and thought

How Loud Can you go? Physical and Physiological Constraints to Producing High Sound Pressures in Animal Vocalizations

Autor: Lasse Jakobsen, Jakob Christensen-Dalsgaard, Peter Møller Juhl, Coen P. H. Elemans

Publikováno v: Frontiers in Ecology and Evolution, Vol 9 (2021)

Sound is vital for communication and navigation across the animal kingdom and sound communication is unrivaled in accuracy and information richness over long distances both in air and water. The source level (SL) of the sound is a key factor in deter

Auditory opportunity and visual constraint enabled the evolution of echolocation in bats

Autor: Jeneni Thiagavel, Clément Cechetto, Sharlene E. Santana, Lasse Jakobsen, Eric J. Warrant, John M. Ratcliffe

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-10 (2018)

Substantial evidence now supports the idea that the ancestral bat was a small, night flying predator capable of laryngeal echolocation. Here, the authors confirm this hypothesis using phylogenetic comparative analyses and further suggest an underlyin

It is well established that the male sex is associated with increased risk for, as well as poorer survival of, most cancers. A similar pattern has been described in lymphomas but has not yet been comprehensively assessed. In this nationwide populatio

Visual detection threshold in the echolocating Daubenton's bat (Myotis daubentonii)

Autor: Clément Céchetto, Lasse Jakobsen, Eric J. Warrant

Publikováno v: Journal of Experimental Biology.

All bats possess eyes that are of adaptive value. Echolocating bats have retinae dominated by rod photoreceptors and use dim light vision for navigation, and in rare cases for hunting. However, the visual detection threshold of insectivorous echoloca

Drone exploration of bat echolocation: A UAV ‐borne multimicrophone array to study bat echolocation

Autor: Christian Jespersen, David Docherty, John Hallam, Carsten Albertsen, Lasse Jakobsen

Publikováno v: Ecology and Evolution. 12

Multimicrophone array techniques offer crucial insight into bat echolocation, yet they severely undersample the environments bats operate in as they are limited in geographic placement and mobility. UAVs are excellent candidates to greatly increase t

Dynamic control of the acoustic scene in echolocating bats

Autor: Lasse Jakobsen, Felix T. Häfele, Danuta M. Wisniewska

Publikováno v: The Journal of the Acoustical Society of America. 153:A94-A94

Echolocating bats can detect, localize, classify, pursue, and capture night-flying insects in less than a second. During pursuit, aerial hawking bats dynamically change their emitted calls as they approach prey, increasing call rate, reducing call du
