The theory of island biogeography and soundscapes: Species diversity and the organization of acoustic communities

Abstract: Aim: On islands, species richness is reduced and interspecific competition relaxed in relation to the mainland, allowing species to use broader ecological niches. These factors are known to affect diet and morphology, but can also affect communication and acoustic signalling in particular. However, no study has ever compared insular and continental soundscapes to determine to which extent islands present reduced acoustic richness (number of co-vocalizing species) and fewer constraints for vocalizing species.Lo… Show more

“…Through spectrogram analysis, researchers can visualize acoustic communities, detect variations in vocalizations, and explore the behavioral implications associated with them (Celis‐Murillo et al., 2009; Gibb et al., 2019; Hedley et al., 2017; Obrist et al., 2010). Bioacoustic analysis in vulnerable conservation areas provides valuable, expansive monitoring and detailed insight into differences among isolated fragments of habitat (Gibb et al., 2019; Mulatu et al., 2017; Robert et al., 2019). While habitat fragmentation's negative effect on biodiversity and genetic diversity is well documented, far less is known about its effects on vocal communication in animals.…”

“…We may then test two contrasting hypotheses: does signal similarity drive spatial segregation in species distributions, or does habitat structure indirectly structure the acoustic community (Sugai et al, 2021a)? Similar analyses have also proved useful in understanding how isolation on islands influences the acoustic community, and thus signal partitioning in birds (Robert et al, 2019). This study framework therefore has great value in understanding the relationship between biogeography and acoustic community structure.…”

“…Community composition is considered as one of the major constraints affecting signal evolution (Wilkins et al, 2013). For instance, many studies recorded frequency partitioning at the community level in insects (Shieh et al, 2015; Sueur, 2002), fish (Ruppé et al, 2015), (Duellman & Pyles, 1983; Sinsch et al, 2012) and birds (Luther, 2009; Robert et al, 2019; but see Slabbekoorn & Planqué, 2008; Seddon & Tobias, 2010, Tobias et al, 2014).…”

“…Small isolated oceanic islands present simplified biotas regarding the mainland, with less species and lower competition (Whittaker et al, 2017). The reduced species richness on islands translates in fewer vocalizing species, resulting in less saturated soundscapes (Robert et al, 2019). Hence, acoustic interference is also expected to decrease on islands.…”
