We evaluated similarity in a contact call of the Military Macaw (Ara militaris) among three populations along the coast of Jalisco, Mexico. We compared contact calls among sites using two approaches i) analysis of specific acoustic parameter measures using GLMM on Principal Components; and ii) evaluation of spectrogram similarity using cross-correlation with a Mantel test to evaluate site and distance effects. Acoustic parameter analysis found that incorporating the site where recordings were obtained significantly explained variation in call features, for both the complete and reduced, balanced dataset. The spectrogram cross-correlations similarity analysis indicated an association with site in spectral similarity of calls, and that call similarity decreased with distance. Our results demonstrated the accumulation of small, fine-scale changes in Military Macaw calls with distance, suggesting that large-bodied non-oscines such as macaws may be able to maintain connectivity among sites by dispersal, facilitating call diffusion, while limited movements among some populations may account for the differentiation among sites in call features.","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/09524622.2020.1714479","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45171664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two experiments were conducted: (1) Nests were threatened in three different contexts to test the effect of increasing motivation on three response variables (call form, rate, amplitude), and (2) a playback study was undertaken to quantify the accomplishments of graded call structures on territory-holders. Results from the two experiments showed that long-distance communication in the focal species is dependent on two concurrent aspects of communication: (1) Acoustic cues to signaller motivation via call rate, (2) spectral cues that reveal directivity – either precisely or imprecisely – that complement the perception of signaller location via distance assessment (ranging). Simultaneously, amplitude and bandwidth are adjusted to beam signals across various distance intervals. Therefore, to affect conspecific behaviour, a signaller can alter vocal cues to manipulate an assessor’s perception of signaller location while revealing motivation. This study reveals the foundational components of short and long-distance communication with the use of simple graded calls by a forest-dwelling oscine passerine. It is similar to long-distance communication networks documented in some parrots, marine mammals, and primates.","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/09524622.2021.1888316","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43377570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, stridulatory organs, sound-producing behaviour and acoustic signals in males of the longhorn beetle Batocera lineolata were investigated for the first time. The detailed morphology of the file and scraper of the stridulatory organ are presented. Behavioural observations showed that sound production was associated with the rapid forward and backward movements of the pronotum. The forward and backward movements of the pronotum can both cause interactions between the file and scraper, and produce forward chirps and backward chirps, respectively. Oscillogram and frequency spectrum comparisons of the upward and backward chirps revealed that the two types of chirps exhibited significant differences in temporal and amplitude features, but had similar spectral characteristics. Acoustic studies on most longhorn beetles are strongly needed, which may make significant contributions in many areas, such as the evolution and diversity of the acoustic behaviour and the possibility of use of sounds in taxonomy of longhorn beetles.","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/09524622.2021.1890640","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43705440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to characterise burst pulses produced by Guiana dolphins and propose a visual method to classify these sounds into structural categories. Data collection occurred during boat surveys in south-eastern Brazil. Five acoustic parameters were extracted: number of pulses, duration, interclick interval, click repetition rate, and minimum frequency. All sounds were visually classified into four categories and used in a discriminant function analysis. In addition, a K-means cluster was used to compare the visual classification with this unsupervised grouping method and confirm the representativeness of each category. According to the discriminant analysis, most sounds were correctly classified (77%) into the four categories. Both methods grouped burst pulses in similar patterns, confirming the use of the categories. Click repetition rate was the most important parameter to separate categories. The variation in this parameter could be related to different behaviours as already suggested for other species. Thus, each category could have a different function in Guiana dolphin communication. The visual classification method is efficient and could be used for other species that produce pulsed sounds.","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/09524622.2021.1886169","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59482982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Continuous low-pitch natural noise can drive changes in both spectral and temporal patterning of bird vocalisations, but the extent to which these effects may also affect birds that lack vocal learning is not well understood. We used a gradient of exposure to natural low-frequency noise to assess whether it exerts selective pressure on innate vocalisations. We tested whether three species of Pogoniulus tinkerbirds adapt their song when exposed to continuous low-frequency noise from ocean surf. We show that dominant frequency increases the closer birds are to the coast in at least two species, indicating that ocean surf sound may apply a selective pressure on songs. Tinkerbirds adapt their songs by increasing dominant frequency to avoid masking by ambient noise, therefore improving long-range communication. Our study provides evidence that natural ambient noise affects vocalisations in birds whose songs develop innately. We believe that our results can also be extrapolated in the context of anthropogenic noise pollution, hence providing a baseline for the study of the effects of low-frequency ambient noise on birds that lack vocal learning.","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/09524622.2021.1879680","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47409916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Females often have a preference for higher amplitude calls. However, if a male is capable of making a louder call than his neighbour he still might be perceived as the quieter of the two, if he is farther away from the female. There is a huge amount of information encoded in male calls and among those is information on distance, or range. As calls travel through air, higher frequency components attenuate faster than lower frequency components. This excess high-frequency attenuation could act as a ranging aid to females. If she hears two males making calls of equal amplitude, but one male has fewer high-frequency components in his call, he is likely farther away. If so, he must be able to make the higher absolute-amplitude call (the amplitude of the call at the sender) of the two. We tested this in Orchelimum pulchellum, a meadow katydid that uses broad spectrum calls. We found that females are more likely to do positive phonotaxis towards a call with excess high-frequency attenuation. This preference exists even when the calls with excess attenuation are quieter.","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/09524622.2021.1879681","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46913933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We recorded and analyzed the two types of advertisement calls produced by Pacific tree frogs, Hyliola regilla: diphasic and monophasic calls. Specifically, we examined (i) the relationship between call properties and both body size and physical condition, (ii) patterns of within- and among-individual variation in call properties, and (iii) acoustic differences between diphasic and monophasic calls. While only one property of diphasic calls correlates with physical condition, spectral properties of both types of calls correlate with body size. Patterns of within- and among-individual variation were similar between call types and, overall, consistent with patterns reported for closely related species. Monophasic calls have lower frequencies, are delivered faster, and have higher call effort and duty cycle than diphasic calls.

However, comparative studies of signal form indicate mixed support for predictions of the AAH. Several studies have employed experimental playback approaches to testing signal transmission which can complement comparative studies. Here, we summarise these experimental playback tests of the AAH in birds, mammals, insects, and anurans, we describe the methodologies used in these tests, and we assess the evidence for habitat-specific signal degradation and species-specific acoustic fidelity (i.e. whether signals propagate best in native versus foreign habitats). Experimental evidence, like comparative evidence, varies across habitats and taxa. Although transmission properties consistently differed by habitat, with closed habitats degrading signals more than open habitats, animal signals were not always adapted to propagate best within their native habitats. Researchers felt they had convincing evidence for species-specific acoustic fidelity in less than half of the 67 reviewed studies, with the most support found for birds and the least for anurans. We discuss potential explanations for differences within and between habitats and taxa and conclude with suggestions for standardised methodology and areas of future research.","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/09524622.2020.1858448","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47657496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
