Acoustic communication is a way of information exchange between individuals, and it used by several animal species. Therefore, the detection, recognition correct understanding acoustic signals are key factors in effective communication. The priority effectiveness rather than perfection, being avoids affecting sound-based system One that can affect overlap time frequency during signal transmission, known as masking. type sound cause masking anthropogenic noise, which currently increasing due to urban growth consequently motorized transportation machinery. When exposed animals use compensatory mechanisms deal with masking, such modification parameters their signal. Here, we performed meta-analysis investigating whether different taxa have general tendency for changes available literature met minimum criteria perform meta-analysis. We hypothesized noise compensation mechanisms, dominant, maximum or frequencies, call duration, note duration rate meta-analysis, synthesized from 73 studies comprising 82 species three taxa: insects, anurans birds. Our results showed presence insects did not change parameters, while increased amplitude birds dominant frequency, songs. responses groups may be related particularities production reception differences considered also lack some taxa.

Global analysis of acoustic frequency characteristics in birds

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 291(2034)

Published: Nov. 1, 2024

Animal communication plays a crucial role in biology, yet the wide variability vocalizations is not fully understood. Previous studies birds have been limited taxonomic and analytical breadth. Here, we analyse an extensive dataset of >140 000 recordings from 8450 bird species, representing nearly every avian order family, under structural causal model framework, to explore influence eco-evolutionary traits on acoustic frequency characteristics. We find that body mass, beak size, habitat associations geography characteristics, with varying degrees interaction song acquisition type. no evidence for vegetation density, sexual dimorphism, range size competition our measures Our results, built decades researchers’ empirical observations collected across globe, provide new breadth about how processes shape communication.

Males increase call frequency, not intensity, in response to noise, revealing no Lombard effect in the little torrent frog

Ecology and Evolution, Journal Year: 2018, Volume and Issue: 8(23), P. 11733 - 11741

Published: Oct. 31, 2018

Noise is one of the main factors that can influence processes sound communication across a wide range animal groups. Although effects ambient noise on communication, including anthropogenic noise, have received increasing attention, few studies examined changes in fine structure acoustic signals produced by vocalizing species constantly noisy environments. Here, we used natural recordings to determine associations between stream and call parameters little torrent frog (Amolops torrentis). We also playbacks recorded habitats white examine how male vocal change with levels. The results show intensity has significant effect frequency, but not amplitude or other characteristics. Based this evidence, suggest streamside drives males alter frequency as loudly possible order improve discriminability. These findings provide insights into role played ecological selection evolution noise-dependent anuran plasticity.

A meta-analysis on the evolution of the Lombard effect reveals that amplitude adjustments are a widespread vertebrate mechanism

Proceedings of the National Academy of Sciences, Journal Year: 2022, Volume and Issue: 119(30)

Published: July 18, 2022

Animal communication is central to many animal societies, and effective signal transmission crucial for individuals survive reproduce successfully. One environmental factor that exerts selection pressure on acoustic signals ambient noise. To maintain efficiency, species can adjust through phenotypic plasticity or microevolutionary response natural selection. of these adjustments the increase in amplitude, called Lombard effect, which has been frequently found birds mammals. However, evolutionary origin effect largely unresolved. Using a phylogenetically controlled meta-analysis, we show also present fish amphibians, contradictory results literature be explained by differences signal-to-noise ratios among studies. Our analysis demonstrates subcortical processes are sufficient elicit amplitude do not require vocal learning. We conclude widespread mechanism based vertebrates coping with changes noise levels.

Competition for acoustic space in a temperate-forest bird community

Behavioral Ecology, Journal Year: 2023, Volume and Issue: 34(6), P. 1043 - 1054

Published: Sept. 23, 2023

Abstract Animals that communicate by acoustic signaling share a common environment. Birds are particularly vocal examples, using wide repertoire of broadcast signals for mate attraction and territorial defense. However, interference caused sounds overlap in frequency time can disrupt signal detection reduce reproductive success. Here, we investigated competition avoidance mechanisms used the bird community inhabiting primeval lowland temperate forest Białowieża, Eastern Poland. We recorded dawn chorus at 84 locations early late spring calculated dissimilarity indices to examine how species with greater song similarities use spatial temporal partitioning avoid space throughout breeding season. The changed its day did not when looked recording over whole study period, but they seasonal context, more acoustically different than expected chance same point part Our results also indicate daily niche may only occur certain times before sunrise, no evidence large-scale between vocalizing during 1-min recordings daytime. These contribute toward our understanding evolution communication highlight strategies employed improve their transmission.

Crabeater seals (Lobodon carcinophaga) are an important component of the Southern Ocean as they most abundant pinniped species in this krill-based ecosystem; however, their acoustic repertoire and ecology remain to be fully described. Seasonal occurrence diel-calling pattern crabeater seal off Maud Rise, eastern Weddell Sea, described using passive monitoring data collected over 8 months (mid-January mid-September) 2014. We describe a new call type seals, short moan (mean 90% duration: 2.2 ± 0.3 (SD) s, peak frequency: 596.5 109.4 Hz, frequency range: 122–1024 Hz), which was only detected 1871 calls were enumerated. Those from April until mid-September (with calling around September), coincided with appearance sea ice. Short rates highest at night August (i.e., 6.4 per minute) September, showed no diel variations for through July. Distance ice edge month year predictors seals.

Traffic noise drives an immediate increase in call pitch in an urban frog

Journal of Zoology, Journal Year: 2021, Volume and Issue: 313(4), P. 307 - 315

Published: Jan. 9, 2021

Abstract Noise pollution is an underappreciated component of global environmental change and can impact species that have a strong reliance on acoustic communication. In urban areas, traffic noise interfere with the ability animals to communicate complete essential aspects their daily lives. We investigated calling behaviour brown tree frog ( Litoria ewingii ) in south‐eastern Melbourne, fastest‐growing human population centre Australia. placed six recorders at increasing distances from busy suburban road recorded (call pitch call rate) frogs immediately before after loud noises, response different chorus sizes. Traffic resulted significant, but short‐term, increase frog. Both rate decreased distance road, yet still increased even 200–300 m road. Conversely, although across all sizes frog, larger were associated pitch. Our study highlights pervasive, sustained, anthropogenic populations.
