Hazardous wildfire smoke events can alter dawn soundscapes in dry forests of central and eastern Washington, United States

As global wildfire activity increases, wildlife are facing greater exposure to hazardous smoke pollution – with unknown consequences for biodiversity. Research on the effects of wild animals is extremely limited, in part due inherent logistical challenges observing how respond real time. Passive acoustic monitoring may be a powerful tool safely and effectively monitor biodiversity before, during, after major events. In this study, we used data collected from large-scale network bioacoustic recorders at 92 sites central eastern Washington state during August–September, 2019–2020 investigate effect dawn soundscapes and, by extension, acoustically active wildlife. We indices document characterize changes related exposure, including Acoustic Complexity Index (ACI), Bioacoustic (BI), Normalized Difference Soundscape (NDSI). Higher values these likely indicate higher levels our study area. hypothesized that would reduce bird vocalizations, leading declines ACI, BI, NDSI dawn, when birds most active. linear quantile regression models test an daily fine particulate matter (PM2.5), marker smoke, mean upper 90th percentile each index dawn. also conducted before-during-after analysis particularly event impacted area September 12–14, 2020. did not observe PM2.5 average or peak indices; however, significant reduction ACI BI three-day 2020 two weeks following air episode.

Noise Pollution in the Center of the Iberian Peninsula: Diversity and Abundance on Urban Birds Breeding

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 2, 2024

In an increasingly urbanized world, biodiversity, and more specifically birdlife located in ecosystems, faces several threats. Among these, noise pollution has proven to be one of the most significant, as it affects effectiveness efficiency acoustic communication. We studied relationship between diversity abundance birds breeding urban areas central region Iberian Peninsula (Spain). analyzed how species density varied across three levels (high, medium, low). Species decreased with high compared sites medium low noise. frequent found within each category. identified eight additional noise-tolerant species, whose had significantly increased environments (e.g. Blackbird, Eurasian Tree Sparrow, Coal Tit). The ten sensitive such Common Linnet, House European Greenfinch, densities when level increased. Identifying sensitivity (the effect) bird is vital for effective conservation management measures sustainable planning cities.
