“…Luther (2009) found that species in an Amazonian bird assemblage singing in the same 30 min interval and in the same forest stratum were more acoustically dispersed in comparison to those singing in different 30 min periods of the morning. Similarly, Planqu e and Slabbekoorn (2008) found lower realized competition for acoustic active space and reduced fine-scale temporal overlap between some species pairs in another Amazonian bird assemblage. They concluded that species whose call bandwidth falls within the most heavily used frequency range actively avoid overlap with each other.…”

“…Similar short-term responses to noise have been observed in other species. Strawberry poison-dart frogs, Oophaga pumilio, show a similar inhibitory response to cicada choruses and respond less to playbacks of conspecifics when cicadas are calling in the background (Paez, Bock, & Rand, 1993). To avoid masking by acoustically dominant heterospecifics, birds in temperate forests have been found to insert their songs directly after songs of dominant species (Ficken et al, 1974;Popp et al, 1985).…”

“…Insects are the most species-rich group of sound-producing animals [42,43], yet most acoustic studies in the tropics have focused on birds, followed by anurans. While the potential role of insects in shaping the evolution of avian and anuran vocalizations has been recognized (e.g., [7,44,45]), few studies have pursued the function of sound-producing insects in driving the structure of ASU in tropical forests. Nonetheless, insects have repeatedly been recommended for use in acoustic monitoring to evaluate changes in biodiversity [46,47].…”

Species Richness (of Insects) Drives the Use of Acoustic Space in the Tropics

Acoustic ecology, or ecoacoustics, is a growing field that uses sound as a tool to evaluate animal communities. In this manuscript, we evaluate recordings from eight tropical forest sites that vary in species richness, from a relatively low diversity Caribbean forest to a megadiverse Amazonian forest, with the goal of understanding the relationship between acoustic space use (ASU) and species diversity across different taxonomic groups. For each site, we determined the acoustic morphospecies richness and composition of the biophony, and we used a global biodiversity dataset to estimate the regional richness of birds. Here, we demonstrate how detailed information on activity patterns of the acoustic community (<22 kHz) can easily be visualized and ASU determined by aggregating recordings collected over relatively short periods (4-13 days). We show a strong positive relationship between ASU and regional and acoustic morphospecies richness. Premontane forest sites had the highest ASU and the highest species richness, while dry forest and montane sites had lower ASU and lower species richness. Furthermore, we show that insect richness was the best predictor of variation in total ASU, and that insect richness was proportionally greater at high-diversity sites. In addition, insects used a broad range of frequencies, including high frequencies (>8000 Hz), which contributed to greater ASU. This novel approach for analyzing the presence and acoustic activity of multiple taxonomic groups contributes to our understanding of ecological community dynamics and provides a useful tool for monitoring species in the context of restoration ecology, climate change and conservation biology.

“…The noise of other chorusing frogs and insects can hinder mate choice by female frogs (Gerhardt and Klump 1988) and interfere with territorial interactions between males (Paez et al 1993). Acoustic interference from natural sources of noise could lead to the modification of calls through selection for more efficient communication (Littlejohn 1965), and acoustic interference from human-generated noise may act similarly (Katti and http://www.ecologyandsociety.org/vol14/iss1/art25/ Warren 2004, Warren et al 2006.…”

ABSTRACT. Male frogs call to attract females for mating and to defend territories from rival males. Female frogs of some species prefer lower-pitched calls, which indicate larger, more experienced males. Acoustic interference occurs when background noise reduces the active distance or the distance over which an acoustic signal can be detected. Birds are known to call at a higher pitch or frequency in urban noise, decreasing acoustic interference from low-frequency noise. Using Bayesian linear regression, we investigated the effect of traffic noise on the pitch of advertisement calls in two species of frogs, the southern brown tree frog (Litoria ewingii) and the common eastern froglet (Crinia signifera). We found evidence that L. ewingii calls at a higher pitch in traffic noise, with an average increase in dominant frequency of 4.1 Hz/dB of traffic noise, and a total effect size of 123 Hz. This frequency shift is smaller than that observed in birds, but is still large enough to be detected by conspecific frogs and confer a significant benefit to the caller. Mathematical modelling predicted a 24% increase in the active distance of a L. ewingii call in traffic noise with a frequency shift of this size. Crinia signifera may also call at a higher pitch in traffic noise, but more data are required to be confident of this effect. Because frog calls are innate rather than learned, the frequency shift demonstrated by L. ewingii may represent an evolutionary adaptation to noisy conditions. The phenomenon of frogs calling at a higher pitch in traffic noise could therefore constitute an intriguing trade-off between audibility and attractiveness to potential mates.
