Many species are currently experiencing anthropogenically driven environmental changes. Among these changes, increasing noise levels are specifically a problem for species relying on acoustic communication. Recent evidence suggests that some species adjust their acoustic signals to man‐made noise. However, it is unknown whether these changes occur through short‐term and reversible adjustments by behavioral plasticity or through long‐term adaptations by evolutionary change. Using behavioral… 
Anthropogenic noise reduces male reproductive investment in an acoustically signaling insect
It was found that male crickets reared in silence developed significantly larger spermatophore molds (a reproductive structure that delivers the sperm containing packet to the female) than those rearing in traffic noise, which may have negative impacts on reproductive success of animals exposed to masking traffic noise.
Environmental variability and acoustic signals: a multi-level approach in songbirds
It is shown that variability in precipitation can explain short-term song complexity among taxonomically diverse songbirds, and that precipitation seasonality and the intensity of sexual selection are related to intraindividual song variation.
Different behavioural responses to anthropogenic noise by two closely related passerine birds
Investigation of the influence of noise on habitat occupancy rates and vocal frequency in two congeneric vireos with similar song features found that vocal plasticity may help some species occupy noisy areas, but because there were no commonalities among the signal changes exhibited by these closely related birds, it is difficult to predict how diverse species may modify their signals in an increasingly noisy world.
Noise-induced vocal plasticity in urban white-crowned sparrows does not involve adjustment of trill performance components
This study explores the maladaptive potential of ISF in the San Francisco, California population of Zonotrichia leucophrys nuttalli by testing for changes in trill bandwidth and rate before and during noise broadcast experiments and finds no evidence that noise induces temporary adjustment of the trill structure traits used by receivers to assess vocal performance.
Social context and noise affect within and between male song adjustments in a common passerine
The hypothesis that male house wrens (Troglodytes aedon) immediately adjust their songs according to changing noise and that social context further modifies responses is tested and males with fertile mates sang lower-frequency songs and increased peak frequency with more neighbors.
Site fidelity and behavioral plasticity regulate an ungulate’s response to extreme disturbance
The effects of the 2018 Mendocino Complex Fire in northern California, USA, on the behavior and body condition of black‐tailed deer are explored and species that exhibit high site fidelity or otherwise fixed behavioral strategies may struggle to cope with increased climate instability and associated extreme disturbance events.
Eastern Bluebirds Alter their Song in Response to Anthropogenic Changes in the Acoustic Environment.
It is suggested that human habitats provide an ideal setting in which to perform experiments on communication strategies, with resulting data poised to reveal underlying evolutionary processes while also informing conservation and management.
Vocal traits and diet explain avian sensitivities to anthropogenic noise
It is suggested that anthropogenic noise is a powerful sensory pollutant that can filter avian communities nonrandomly by interfering with birds' abilities to receive, respond to and dispatch acoustic cues and signals.
Species sensitivities to a global pollutant: A meta‐analysis on acoustic signals in response to anthropogenic noise
It was found that animals changed acoustic signals when exposed to noise, but the magnitude and the direction of adjustments differed among species, highlighting the necessity to assess the effect of environmental stressors not only for a few species but also for many species.

The results provide the first quantitative support of Baldwin’s proposition that plasticity can be crucial for population persistence during the early stages of colonization.
Adaptive Phenotypic Plasticity in Response to Climate Change in a Wild Bird Population
Using a 47-year population study of the great tit in the United Kingdom, it is shown that individual adjustment of behavior in response to the environment has enabled the population to track a rapidly changing environment very closely.
Climate change and evolution: disentangling environmental and genetic responses
The available evidence points to the overall conclusion that many responses perceived as adaptations to changing environmental conditions could be environmentally induced plastic responses rather than microevolutionary adaptations, and clear‐cut evidence indicating a significant role for evolutionary adaptation to ongoing climate warming is conspicuously scarce.
Birdsong and anthropogenic noise: implications and applications for conservation
It is hypothesized that behavioural plasticity in singing behaviour may allow species more time to adapt to human‐altered environments and the potential for microevolutionary changes and urban speciation in European blackbirds (Turdus merula) is addressed.
Effects of urban noise on song and response behaviour in great tits
There is a difference in spectral aspects of rural and urban song in a common passerine, the great tit Parus major, at 20 sites across the UK and this is the first demonstration that such environmentally induced differences in song influence the response of male territory holders.
Habitat-related birdsong divergence: a multi-level study on the influence of territory density and ambient noise in European blackbirds
It is found that at the level of individual territories, temporal features, but not spectral ones, are correlated to territory density and seasonality, which suggests that short-term individual variation can indeed contribute to habitat-dependent divergence at the population level.
It is suggested that, depending on the species-specific nature of the sexual selection process in relation to the sender songs, ambient noise may impair the probability of reproduction to different degrees in different species.
The role of phenotypic plasticity in driving genetic evolution
The role of phenotypic plasticity in stimulating evolution is assessed by considering two examples from birds: (i) the evolution of red and yellow plumage coloration due to carotenoid consumption; and (ii) the Evolution of foraging behaviours on islands.
