The shifts of bird song frequencies in urbanized areas provide a unique system to understand avian acoustic responses urbanization. Using passive monitoring and automatic sound recognition technology, we explored the frequency variations six common urban species their associations with habitat structures. Our results demonstrated that were significantly higher than those peri-urban rural areas. Anthropogenic noise structure identified as crucial factors shaping space for birds. We found noise, urbanization, open understory spaces are contributing increase dominant sounds. However, variables such vegetation density tree height can potentially slow down this upward trend. These findings offer essential insights into behavioral response birds variety forest habitats, implications ecosystem management restoration.

ABSTRACT Eavesdropping predators, parasites and parasitoids exploit signals emitted by their prey hosts for detection, assessment, localization attack, in the process impose strong selective pressures on communication systems of organisms they exploit. Signallers have evolved numerous anti‐eavesdropper strategies to mitigate trade‐off between costs imposed from signal exploitation need conspecific communication. Eavesdropper fall along a continuum opportunistic highly specialized, tightness eavesdropper–signaller relationship results differential systems. A wide variety eavesdropper Antagonistic selection eavesdroppers can result diverse outcomes including modulation signalling displays, structure, evolutionary loss or gain population. These often reduced conspicuousness decreased ornamentation. enemies, however, also promote While less common, this alternative outcome offers unique opportunity dissect factors that may lead different pathways. In addition, contrary traditional assumptions, no sensory modality is completely ‘safe’ as are ubiquitous broad array filters allow exploitation. We discuss how anthropogenic change affects interactions eavesdropping enemies victims it rapidly modifies environments community composition. Drawing research range taxa modalities, we synthesize current knowledge strategies, challenges field highlight fruitful new directions future research. Ultimately, review conceptual framework understand used signallers communicate under pressure enemies.

Several researchers have tried to find relationships between acoustic indices and vocal animal communities use as a passive monitoring method, human-derived surveys are expensive, time-consuming, suffer from observer bias. However, supplanting manual with is daunting task, considering effective for biological need differentiate biologically relevant sounds the broader soundscape, including anthropophony geophony. The objective of our study was test how well can be applied avian community within temperate grassland ecosystem in North America. We collected data calculated six commonly used recordings an intact lowland tallgrass prairie Central Platte River Valley Nebraska throughout breeding seasons 2019–2021. Singular had only weak correlations all metrics. multivariate models multiple showed potential bird abundance when considered. Fragmented remnants likely experience significant that needs accounted populations. Additionally, incorporating several may provide more accurate prediction biophony than individual indices.

Acoustic communication plays a prominent role in various ecological and evolutionary processes involving social interactions. The properties of acoustic signals are thought to be influenced not only by the interaction between signaller receiver but also characteristics environment through which signal is transmitted. This conjecture forms core so-called "acoustic adaptation hypothesis" (AAH), posits that vegetation structure affects frequency temporal parameters emitted as function their degradation properties. Specifically, animals densely vegetated 'closed habitats' expected produce longer with lower repetition rates frequencies (minimum, mean, maximum, peak) compared ones inhabiting less 'open habitats'. To date, this hypothesis has received mixed results, level support depending on taxonomic group methodology used. We conducted systematic literature search empirical studies testing for an effect signalling assessed generality AAH using meta-analytic approach based 371 sizes from 75 57 taxa encompassing birds, mammals amphibians. Overall, our results do provide consistent AAH, neither within-species comparisons (suggesting no overall phenotypically plastic response structure) nor among-species response). However, when considering birds only, we found weak comparisons, was mainly driven measured bandwidth, suggesting variable may exhibit structure. For significant after excluding comparative did account phylogenetic non-independence. Collectively, synthesis does universal evolution communication. highlight need more work currently under-studied such amphibians, mammals, insects. Furthermore, propose framework future research AAH. specifically advocate detailed quantitative characterization habitats identify highest detection probability determine if greater distances preferentially Finally, stress tests should focus selected increased transmission distance.

Abstract Research on urban noises affecting acoustic communication of animals is a growing area study and conservation concern. However, the consequences aircraft noise anuran have been explored restricted basis to date. In this study, we investigated impact overflights individual chorus performance signalling in Pedregal frog ( Eleutherodactylus grandis ), microendemic threatened species from Mexico City. During summer 2021, recorded signals male individuals conducted monitoring analyse how social interactions change due overflights. For purpose, evaluated properties call, including call duration, dominant frequency, amplitude, repetition rate. Additionally, measured amplitude environmental by means two types complementary methodological approaches. Our results show changes with longer lower higher overflights, while rate did not vary. Furthermore, decrease number calls within was observed during overflight. Overall, these that causes plastic between conspecifics decrease, thus adding new disturbance already suffers other anthropogenic noises, habitat fragmentation.

Rising temperatures and anthropogenic noise are two of the most pervasive well researched stressors affecting avian species globally. Despite often triggering similar behavioural responses in birds, frequently co‐occurring (particularly urban areas), impact these primarily investigated isolation. Here, we discuss compare commonly effects rising on behaviour. We then outline recent findings impacts cognition which underpins many adjustments. find that both high temperatures, when isolation, behaviours such as foraging, antipredator response, interactions with conspecifics. also can lead to cognitive impairment, but occurrence magnitude impairment varies depending trait examined. Finally, limited studies have simultaneously different scenarios additive, synergistic, or antagonistic may occur. hope our review will stimulate researchers investigate simultaneous other behaviour urban‐living wild birds.

Abstract Anthropophony is a prominent component of soundscapes worldwide and known to impact biota. While responses anthropophony in terrestrial marine animals have been relatively well-studied, there still lack knowledge regarding freshwater animals. In fact, taxa are among the possibly most threatened groups, unveiling reasons for their threat crucial. We investigated effect low-frequency sounds -usually associated with anthropophony- on stridulation Krizousacorixa femorata , common water bug Mexico City. Using aerial recordings, we estimated Normalized Difference Soundscape Index (NDSI), which commonly used index measure anthropophony, characterize six city sites throughout year. Additionally, from underwater recordings same sites, obtained peak frequency (Pf) stridulations, as it highest energy and, therefore, one that can travel farthest be identified even presence overlapping sounds. Finally, evaluated relationships between Pf through mixed linear model. There was negative correlation NDSI Pf, indicating higher-pitched stridulations at dominant anthropophony. cannot rule out other factors contributing variation, remain uncertain about how ecosystems intricate relationship aquatic life urban settings.

Abstract Acoustic communication in animals can be affected by multiple biotic (intra and interspecific) abiotic (e.g., wind rain) natural noises. In addition, human beings produce additional novel sources of noise, which reduce or inhibit the reception acoustic signals conspecifics, leading to behavioral changes. this study, we investigated whether sound conspecifics road noise additively affect parameters advertisement call males a Yellow Heart‐tongued Frog ( Phyllodytes luteolus ). We hypothesized that vocalize choruses (males calling nearby) areas close highways (anthropic noise) will increase their temporal spectral parameters, respectively, avoid signal masking. recorded vocalizations 38 environments N = 18) distant 20) from different social contexts (many few individuals nearby). Contrary our expectation, results indicated had lower dominant frequency calls than those (far highways), density chorus no influence on parameters. Furthermore, found positive relationship between body size intensity, indicating larger emit reach greater distances. The has high frequency, with little overlap anthropic noises (roads), may explain its presence reproductive success species bromeliads urbanized areas.
