“…Although there has been some support for the hypothesis from work with birds and mammals (Boncoraglio and Saino, 2007;Brumm and Naguib, 2009;Ey and Fischer, 2009), to date for anurans, there have been relatively few data generated consistent with its predictions (Ey and Fischer, 2009;Wells, 2007). Our study was not designed to test the hypothesis directly but our results bear important relevance to it.…”

“…The acoustic adaptation hypothesis posits that selection on signalers has yielded signals with characteristics well suited to propagation in those habitats in which the animals most often communicate (Boncoraglio and Saino, 2007;Ey and Fischer, 2009;Ryan and Kime, 2003).

“…These constraints potentially act as sources of selection that can influence the evolution of how signals are designed (Boncoraglio and Saino, 2007;Ey and Fischer, 2009;Ryan and Kime, 2003), how signalers behave to produce signals in time and space (Brumm and Slabbekoorn, 2005;Ryan and Kime, 2003) and how the auditory systems of receivers extract biologically relevant signal properties (Bee and Micheyl, 2008;Brumm and Slabbekoorn, 2005;Langemann and Klump, 2005). In addition, receivers in some taxa can actually use the extent of degradation in acoustic signals to obtain information about the distance to signalers (Naguib and Wiley, 2001).…”

SUMMARYAcoustic communication signals degrade as they propagate between signalers and receivers. While we generally understand the degrading effects of sound propagation on the structure of acoustic signals, we know considerably less about how receivers make behavioral decisions based on the perception of degraded signals in sonically and structurally complex habitats where communication occurs. In this study of acoustic mate recognition in Cope's gray treefrog, Hyla chrysoscelis (Cope 1880), we investigated how the temporal structure of male advertisement calls was compromised by propagation in a natural habitat and how females responded to stimuli mimicking various levels of temporal degradation. In a sound transmission experiment, we quantified changes in the pulsed structure of signals by broadcasting synthetic calls during active choruses from positions where we typically encountered signalers, and re-recording the signals from positions where we typically encountered potential receivers. Our main finding was that the silent gaps between pulses become increasingly 'filled in' by background noise and reverberations as a function of increasing propagation distance. We also conducted female phonotaxis experiments to determine the threshold modulation depth required to elicit recognition of the pulsatile structure of the call. Females were surprisingly tolerant of degraded temporal structure, and there was a tendency for greater permissiveness at lower playback levels. We discuss these results in terms of presumed mechanisms of call recognition in complex environments and the acoustic adaptation hypothesis.

“…Propagation effects of vegetation on song transmission and the phenomenon of habitatdependent song variation have been reported especially for forest habitat (Slabbekoorn 2004;Ey and Fischer 2009), but also reed stalks are known to filter selectively and provide better propagation conditions for low than for high song frequencies (Cosens and Falls 1984). An important fact may be that the warble is sung in flight and may be largely free of excess attenuation, but that the trill is predominantly sung perched and may have a transmission pathway to potential receivers through dense vegetation.…”

Distinct song parts of the endemic marsh grassbird of China vary with latitude and climate among migratory and sedentary populations

Birdsong can act as a premating barrier to gene flow through its role in mate attraction and territorial defence. The link between geographic variation in song structure and ecological factors is key to the process of acoustically guided population divergence and isolation. Migratory behaviour is an example of such an ecological factor. In this study, we asked whether latitude and climate can explain song variation among migratory and sedentary populations of the marsh grassbird (Locustella pryeri sinensis), a rare songbird endemic of wetlands of eastern and northeastern China. We investigated two structurally different song parts: a repeating trill part followed by a more variable warble part. We found significant variation in acoustic structure and distinct divergence patterns between the two song parts across a latitudinal gradient and strong acoustic correlations with several bioclimatic variables. The trill part showed an increase in maximum frequency with latitude and the warble part became longer with fewer element types towards three higher latitude, migratory populations. These patterns are in line with a dual function of both song parts, increased sexual selection pressure at higher latitude and a complex impact of climate on song through vegetation and weather conditions.
