“…For their part, Rajan et al have used acoustic analysis to assess the effects of a natural disaster (flooding) on avian diversity in Kerala, India. Finding that reduced soundscape variability following floods in 2018 ‘indicate reduced avian species richness’, the authors underline the importance of acoustic ecology for the purpose of ‘rapid assessment of biodiversity’ (Rajan et al, 2022) – an issue highly pertinent to the recent discussions that took place at the United Nations biodiversity conference (COP 15) in Montreal.…”

There exists a rich corpus of literature exploring some of the diverse roles – positive and negative – that music can play in war. This interdisciplinary article makes a novel contribution to this literature, and to research on the sociology of music more broadly, through its particular emphasis on resilience. Scholarship on resilience has increasingly moved beyond person-centred, psychology-based approaches towards more complex relational and multi-systemic framings that situate the concept in the interactions between individuals and their social ecologies (environments). However, it has given little attention to the sensory dimensions of these ecologies, including their acoustic dimensions. Focusing on the war in Ukraine and drawing primarily on media sources (including several online videos) to develop its analysis, the article argues that music can be a form and expression of resilience (and resistance) in war situations that directly acts on the acoustic ecology – a concept that to date has mainly been discussed within ecology and conservation research. Specifically, the article frames music as a form of ‘soundscaping’, in the sense of an active aligning of sound and wellbeing.

“…Of the few studies that have used acoustic monitoring to capture storms or extreme events, most focused on marine soundscapes (Boyd et al, 2021;Locascio & Mann, 2005;Simmons et al, 2021), though Gottesman et al (2021) recently showed that terrestrial soundscapes were less resistant than those of coral reefs to hurricane disturbance. Embedded within terrestrial soundscapes, bird vocalisations provide the opportunity to assess the impact of typhoons on critical indicator taxa (Gasc et al, 2017), while acoustic indices provide rapid information on a combination of biodiversity and other meaningful aspects of soundscape change (Bradfer-Lawrence et al, 2020;Harris et al, 2016;Rajan et al, 2022). There are, however, few studies that simultaneously assess both individual species vocalisations and acoustic indices explicitly (Ferreira et al, 2018;Ross et al, 2018).…”

“…However, the high-resolution time series afforded by passive acoustic monitoring allows opportunistic measurement of soundscape responses to infrequent disturbance events, such as typhoons (e.g., Gottesman et al, 2021), as well as documenting longer-term trends under climate change (Sueur et al, 2019). Acoustic monitoring thus provides an opportunity to overcome many of the challenges associated with studying extreme weather events, by allowing preand post-typhoon comparisons (Altwegg et al, 2017;Rajan et al, 2022), and capturing ecological responses to typhoons across scales in space and time (Lin et al, 2020) using a multidimensional stability framework (Donohue et al, 2013).

Climate change is increasing the frequency, intensity, and duration of extreme weather events across the globe. Understanding the capacity for ecological communities to withstand and recover from such events is critical. Typhoons are extreme weather events that are expected to broadly homogenise ecosystems through structural damage to vegetation and longer-term effects of salinization. Given their unpredictable nature, monitoring ecological responses to typhoons is challenging, particularly for mobile animals such as birds. Here, we report spatially variable ecological responses to typhoons across terrestrial landscapes. Using a high temporal resolution passive acoustic monitoring network across 24 sites on the subtropical island of Okinawa, Japan, we found that typhoons elicit divergent ecological responses among Okinawa's pristine forests, as indicated by increased spatial variability of biological sound production (biophony) among forested sites. However, no such post-typhoon shift in variability was observed among developed urban or agricultural sites. This indicates that natural forests have a diversity of pathways through which communities can respond to typhoons, whereas land use development produces communities more constrained in their disturbance responses. That is, spatial insurance effects among forest communities may provide resilience to typhoons at the landscape scale, but this spatial insurance was diminished by habitat degradation through land use development. Though site-level typhoon impacts on soundscapes and bird detections were not particularly strong, we nevertheless revealed spatial heterogeneity in typhoon responses, owing to the data resolution afforded to us by monitoring at scale (high temporal resolution, broad spatial extent). Our findings underscore the importance of natural forests in insuring ecosystems against disturbance, and demonstrate the potential of landscape-scale acoustic sensor networks for documenting the understudied ecological impacts of unpredictable extreme weather events.

Climate change is increasing the frequency, intensity, and duration of extreme weather events across the globe. Understanding the capacity for ecological communities to withstand and recover from such events is critical. Typhoons are extreme weather events that are expected to broadly homogenize ecological dynamics through structural damage to vegetation and longer‐term effects of salinization. Given their unpredictable nature, monitoring ecological responses to typhoons is challenging, particularly for mobile animals such as birds. Here, we report spatially variable ecological responses to typhoons across terrestrial landscapes. Using a high temporal resolution passive acoustic monitoring network across 24 sites on the subtropical island of Okinawa, Japan, we found that typhoons elicit divergent ecological responses among Okinawa's diverse terrestrial habitats, as indicated by increased spatial variability of biological sound production (biophony) and individual species detections. This suggests that soniferous communities are capable of a diversity of different responses to typhoons. That is, spatial insurance effects among local ecological communities provide resilience to typhoons at the landscape scale. Even though site‐level typhoon impacts on soundscapes and bird detections were not particularly strong, monitoring at scale with high temporal resolution across a broad spatial extent nevertheless enabled detection of spatial heterogeneity in typhoon responses. Further, species‐level responses mirrored those of acoustic indices, underscoring the utility of such indices for revealing insight into fundamental questions concerning disturbance and stability. Our findings demonstrate the significant potential of landscape‐scale acoustic sensor networks to capture the understudied ecological impacts of unpredictable extreme weather events.
