Developmental programming by prenatal sounds: insights into possible mechanisms

Journal of Experimental Biology, Journal Year: 2024, Volume and Issue: 227(Suppl_1)

Published: March 7, 2024

ABSTRACT In recent years, the impact of prenatal sound on development, notably for programming individual phenotypes postnatal conditions, has increasingly been revealed. However, mechanisms through which affects physiology and development remain mostly unexplored. Here, I gather evidence from neurobiology, developmental biology, cellular biology bioacoustics to identify most plausible modes action developing embryos. First, revealing often-unsuspected plasticity, discuss how may shape auditory system determine individuals' later capacity receive acoustic information. also consider hormones, including thyroid glucocorticoids androgen, plasticity. Second, review what is known about transduction other – non-auditory brain regions, its potential input classical pathways. Namely, pathway direct anatomical functional connectivity hippocampus, amygdala and/or hypothalamus, in mammals, birds anurans. Sound can thus trigger both immediate delayed responses these limbic are specific stimulus biological relevance. Third, beyond brain, briefly possibility directly affect functioning, based earless organisms (e.g. plants) cell cultures. Together, multi-disciplinary gathered here shows that wired allow multiple physiological effects sound. Overall, there many unexplored, but possible, pathways even primitive or immature organisms. Throughout, promising research avenues unravelling processes programming.

Growing up with chronic traffic noise exposure leads to transient but not long-term noise tolerance in a songbird

Biology Letters, Journal Year: 2025, Volume and Issue: 21(1)

Noise pollution is on the rise worldwide. An unresolved issue regarding mitigation of noise whether and at which timescales animals may adapt to pollution. Here, we tested continuous highway exposure perinatally during juvenile development increased tolerance in a songbird, zebra finch ( Taeniopygia castanotis ). Breeding pairs were exposed recordings from pre-egg-laying until their offspring reached subadulthood. Subsequently, for both as subadults adults spatial preference test, where birds could choose enter aviaries with different levels noise. Unlike control that preferentially chose quiet aviaries, noise-reared exhibited no preferences first test. However, when experimental retested after two months without exposure, they now avoided previously tolerated preferred quieter aviary. The observed directly release treatment was thus only transient. Growing up chronic did not increase subjects’ tolerance, meaning least this songbird species, adaptation unlikely arise developmental time scale.

A Systematic Review of Anthropogenic Noise Impact on Avian Species

Current Pollution Reports, Journal Year: 2024, Volume and Issue: unknown

Abstract Purpose of review This study aims to investigate anthropogenic noise impact on avian species by means a systematic literature. Recent findings Based previous frameworks, it was possible to: clarify the impacts birds; optimise existing frameworks with produced over 44 years; recategorise into more appropriate categories, indicating which are positive and negatives, as well acute chronic caused noise; provide significant cluster model subdivided ‘Behaviour’ ‘Communication/Perception’ (Cluster 1) ‘Physiology’ 2); show how hearing frequency range overlaps source range. Summary research adopted database Peacock et al. [1, 2] regarding due its vast coverage across taxa. A literature 50 peer-reviewed papers about birds undertaken. Two-Step Cluster analysis calculated, showing data two clusters. 1 (76.9%) showed behavioural responses mainly composed negative auditory perception communication impacts, presenting or impacts. 2 (23.1%) physiological outcomes traffic, anthropogenic, background noise.

Differential impact of anthropogenic noise during the acoustic development of begging calls in Blue Tits (Cyanistes caeruleus)

Ibis, Journal Year: 2024, Volume and Issue: 166(3), P. 1064 - 1072

In many bird species, nestling begging signals play a key role in the interaction between parents and their offspring during development. The information conveyed by calls can be disrupted anthropogenic noise, which is one of major threats to biodiversity increasingly urbanized landscapes. Here, we describe developmental change acoustic structure Eurasian Blue Tits Cyanistes caeruleus ; are pure‐tone, low‐frequency, soft first days development gradually turn into white‐noise, hiss‐like, powerful broadband frequency. This strong variation highlights importance an extended sampling scheme studies. Furthermore, pinpoint two phases where could most vulnerable masking noise. First, early development, very low‐pitched, closer high‐intensity noise bands traffic Secondly, around day 11, show reduced tonality, implies higher degradation, relatively low amplitude, signal range. We encourage future research other provide robust foundation that will make mitigation policies more effective.

Danas su suvremene prometnice jedne od najvećih zagađivača čovjekova okoliša. Zagađenje bukom utječe i na zdravlje, što se manifestira fizičkim, fiziološkim psihološkim učincima. Buka u gradskim sredinama nepovoljno pojedine populacije gradskih životinja, prije svega ptica. U ovom radu daje pregled stručne znanstvene problematike koja je vezana za interakcije buke gradskog zelenila s posebnim osvrtom bioraznolikost. Veći naglasak stavljen problematiku primjene voćnih ukrasnih vrsta javnim zelenim površinama cilju očuvanja ptičje raznolikosti. smanjenja prometa najčešće koriste različite zvučne barijere, a zadnje vrijeme uporabi zelene vertikalne barijere. One ujedno smanjuju buku služe smanjenje zagađenja zraka. Gradsko zelenilo ima niz pozitivnih učinaka zdravlje buke. Vertikalni vrtovi također daju određeni nivo izolacije akumulacije zvuka. Tako npr. poznato da biljni pokrovi učinkovitije ublažuju zvukove viših frekvencija odnosu niže. Potom krovni osim toplinske intenzitet buke, neke zemlje ih zakonski uvjetovale. Postoje određene specifičnosti biljnih učinak Uz navedeno bitno istaknuti postoji načina sadnje odgovarajućeg bilja još k tome ako autohtono utječemo očuvanje bioraznolikosti. Odabir prikladnih jako važan život ptica gradu. prema primjeni prostoru navode specifične vrste prikladne ptice. provedbi bioraznolikosti vrlo važno informirati educirati građane o predmetnoj problematici.
