The soundscape of the Anthropocene ocean

Science, Journal Year: 2021, Volume and Issue: 371(6529)

Published: Feb. 4, 2021

Oceans have become substantially noisier since the Industrial Revolution. Shipping, resource exploration, and infrastructure development increased anthrophony (sounds generated by human activities), whereas biophony of biological origin) has been reduced hunting, fishing, habitat degradation. Climate change is affecting geophony (abiotic, natural sounds). Existing evidence shows that affects marine animals at multiple levels, including their behavior, physiology, and, in extreme cases, survival. This should prompt management actions to deploy existing solutions reduce noise levels ocean, thereby allowing reestablish use ocean sound as a central ecological trait healthy ocean.

Terrestrial Passive Acoustic Monitoring: Review and Perspectives

BioScience, Journal Year: 2018, Volume and Issue: 69(1), P. 15 - 25

Published: Oct. 21, 2018

Passive acoustic monitoring (PAM) is quickly gaining ground in ecological research, following global trends toward automated data collection and big data. Using unattended sound recording, PAM provides tools for long-term cost-effective biodiversity monitoring. Still, the extent of potential this emerging method terrestrial ecology unknown. To quantify its application guide future studies, we conducted a systematic review PAM, covering 460 articles published 122 journals (1992–2018). During period, PAM-related studies showed above fifteenfold rise publication covered three developing phases: establishment, expansion, consolidation. Overall, research was mostly focused on bats (50%), occurred northern temperate regions (65%), addressed activity patterns (25%), recorded at night (37%), used nonprogrammable recorders (61%), performed manual analysis (58%), although their applications continue to diversify. The agenda should include addressing development standardized procedures, analysis, initiatives expand multiple taxa regions.

Anthropogenic noise increases fish mortality by predation

Nature Communications, Journal Year: 2016, Volume and Issue: 7(1)

Published: Feb. 5, 2016

Noise-generating human activities affect hearing, communication and movement in terrestrial aquatic animals, but direct evidence for impacts on survival is rare. We examined effects of motorboat noise post-settlement physiology a prey fish species its performance when exposed to predators. Both playback disturbance by motorboats elevated metabolic rate Ambon damselfish (Pomacentrus amboinensis), which stressed responded less often rapidly simulated predatory strikes. Prey were captured more readily their natural predator (dusky dottyback, Pseudochromis fuscus) during exposure compared with ambient conditions, than twice as many consumed the field experiments passing. Our study suggests that common source marine environment has potential impact demography, highlighting need include anthropogenic management plans.

Noise pollution is pervasive in U.S. protected areas

Science, Journal Year: 2017, Volume and Issue: 356(6337), P. 531 - 533

Published: May 4, 2017

Anthropogenic noise threatens ecological systems, including the cultural and biodiversity resources in protected areas. Using continental-scale sound models, we found that anthropogenic doubled background levels 63% of U.S. area units caused a 10-fold or greater increase 21%, surpassing known to interfere with human visitor experience disrupt wildlife behavior, fitness, community composition. Elevated was also critical habitats endangered species, 14% experiencing levels. However, areas more stringent regulations had less noise. Our analysis indicates pollution is closely linked transportation, development, extractive land use, providing insight into where mitigation efforts can be most effective.

Unmanned aircraft systems as a new source of disturbance for wildlife: A systematic review

PLoS ONE, Journal Year: 2017, Volume and Issue: 12(6), P. e0178448 - e0178448

Published: June 21, 2017

The use of small Unmanned Aircraft Systems (UAS; also known as "drones") for professional and personal-leisure is increasing enormously. UAS operate at low altitudes (<500 m) in any terrain, thus they are susceptible to interact with local fauna, generating a new type anthropogenic disturbance that has not been systematically evaluated. To address this gap, we performed review the existent literature about animals' responses flights conducted pooled analysis data determine probability intensity disturbance, identify factors influencing reactions towards aircraft. We found wildlife depended on both attributes (flight pattern, engine size aircraft) characteristics animals themselves (type animal, life-history stage level aggregation). Target-oriented flight patterns, larger sizes, fuel-powered (noisier) engines evoked strongest wildlife. Animals during non-breeding period large groups were more likely show behavioral UAS, birds prone react than other taxa. discuss implications these results context suggest guidelines conservationists, users manufacturers minimize impact UAS. In addition, propose legal framework needs be adapted so appropriate actions can undertaken when negatively affected by emergent practices.

Chronic anthropogenic noise disrupts glucocorticoid signaling and has multiple effects on fitness in an avian community

Proceedings of the National Academy of Sciences, Journal Year: 2018, Volume and Issue: 115(4)

Published: Jan. 8, 2018

Anthropogenic noise is a pervasive pollutant that decreases environmental quality by disrupting suite of behaviors vital to perception and communication. However, even within populations noise-sensitive species, individuals still select breeding sites located areas exposed high levels, with largely unknown physiological fitness consequences. We use study system in the natural gas fields northern New Mexico test prediction exposure causes glucocorticoid-signaling dysfunction community secondary cavity-nesting birds. In accordance these predictions, across all we find strong support for decreasing baseline corticosterone adults nestlings and, conversely, increasing acute stressor-induced nestlings. also document consequences increased form reduced hatching success western bluebird (Sialia mexicana), species most likely nest noisiest environments.

Ecological impacts of human‐induced animal behaviour change

Ecology Letters, Journal Year: 2020, Volume and Issue: 23(10), P. 1522 - 1536

Published: July 24, 2020

Abstract A growing body of literature has documented myriad effects human activities on animal behaviour, yet the ultimate ecological consequences these behavioural shifts remain largely uninvestigated. While it is understood that, in absence humans, variation behaviour can have cascading species interactions, community structure and ecosystem function, we know little about whether type or magnitude human‐induced translate into detectable change. Here synthesise empirical theory to create a novel framework for examining range behaviourally mediated pathways through which may affect different functions. We highlight few studies that show potential realisation some pathways, but also identify numerous factors dampen prevent consequences. Without deeper understanding risk wasting valuable resources mitigating with relevance, conversely mismanaging situations do drive The presented here be used anticipate nature likelihood outcomes prioritise management among widespread shifts, while suggesting key priorities future research linking ecology.

Published: March 22, 2021

Significance This study examines evidence of the health benefits natural soundscapes and quantifies prevalence restorative acoustic environments in national parks across United States. The results affirm that sounds improve health, increase positive affect, lower stress annoyance. Also, analyses reveal many park sites with a high abundance sound low anthropogenic sound. Raising awareness at provides opportunities to enhance visitor outcomes. Despite more abundant sound, urban frequently visited offered exposure associated benefits, making them valuable target for soundscape mitigation. Our analysis can inform spatial planning focuses on managing human experiences.
