Particularly in males, it plays a crucial role in processes like male competition or sexual selection. Additionally, voice can provide a cue for body size assessment. This study investigates the relationship between male voice characteristics and physical features (assessed by women) and determines the accuracy of these assessments. Three groups of female judges assessed 60 male voices (20 different voices per group) across seven categories of male physical features: height, body fat, musculature, body shape, hirsuteness, age and strength. Recordings of five vowels and sentence and number of anthropometric measurements were made for each of the studied men. Intra- and extragroup agreement of assessments of men’s physical characteristics was demonstrated. Men with lower fundamental frequency (F0 ) and lower formant dispersion (Df ) values were perceived as being heavier, older, stronger and more likely to have chest hair. However, across all the analysed fields of assessment, no accuracy was registered between estimates and men’s actual physical characteristics. These findings suggest that females were guided by stereotypes in their assessment of men’s appearance from voice alone. We propose the size exaggeration hypothesis as an explanation of this phenomenon","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42239801","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 is especially true of less evident sources of noise like wind farms and highly exploited areas, as in the Brazilian semi-arid region. Here, we evaluated the influence of wind farm noise on anuran assemblages’ diversity at the Caatinga, a seasonal dry tropical forest in Brazil. We tested the hypothesis that wind farm noise negatively affects the diversity of anuran assemblages in terms of abundance, species richness and composition. Anurans were sampled in 19 temporary ponds along a noise gradient in two wind farms over a rainy season (March to August). A total of 2,047 individuals belonging to 20 species were recorded. Our results suggest that wind farm noise has a non-significant relationship with anuran diversity patterns (species richness, composition and abundance). To our knowledge, this is the first investigation into the effects of wind farm noise on anuran assemblages in the Caatinga dry forest. Despite our results suggesting that anuran diversity is insensitive to noise pollution caused by wind farms, identification of emerging threats is essential to mitigate impacts on anuran populations which are declining globally.","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43958535","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}

However, successful automated classification of anuran vocalisations in large audio datasets has been limited. We deployed five autonomous recording units at three known breeding areas of the Yosemite toad (Anaxyrus canorus), which is threatened and relatively uncommon, and the sympatric Pacific chorus frog (Pseudacris regilla), which is widespread and more common, to test the viability of bioacoustics as a means of supplementing ongoing, human survey efforts. We analysed the audio data with the BirdNET algorithm, which was originally developed for birds but has been expanded to include both species. We achieved efficient and accurate identification of both species in 2,756 h of audio, which yielded high-resolution phenological data about seasonal and daily vocal activity as well as daily detection counts. These findings demonstrate that a newly expanded machine learning detector, BirdNET, can effectively process passive acoustic surveys for these species.

To quantify this, its performance for species detection must be directly compared to that obtained using traditional observer-based monitoring (OBM). Here, we review such comparisons across all major terrestrial vertebrate classes and identify factors impacting PAM performance. From 41 studies, we found that while PAM-OBM comparisons have been made for all major terrestrial vertebrate classes, most comparisons have focused on birds (65%) in North America (52%). PAM performed equally well or better (61%) compared to OBM in general. We found no statistical difference between the methods for total number of species detected across all vertebrate classes (excluding reptiles); however, recording period and region of study influenced the relative performance of PAM, while acoustic analysis method and which method sampled for longer overall showed no impact. Further studies comparing PAM performance in non-avian vertebrates using standardised methods are needed to investigate in more detail the factors that may influence PAM performance. While PAM is a valuable tool for vertebrate surveys, a combined approach with targeted OBM for non-vocal species should achieve the most comprehensive assessment of terrestrial vertebrate communities.","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48193142","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 used 238 advertisement calls of 34 populations of Amazonian nurse frogs from two Amazonian rainforests with different vegetation density to test if tree density influences the evolution of acoustic parameters. We used PGLS to test for relationships between acoustic traits and phenotypic, environmental and geographic predictors. Spectral and temporal features of calls have an allometric relationship with body size. We found a novel quadratic relationship between note duration and body size. The allometric relationship between dominant frequency and body size and a direct effect of tree density indicates that the evolutionary trajectories of Amazonian nurse frogs follow a general macro-evolutionary pattern as in birds. The temporal features of calls have opposite evolutionary trajectories to those predicted by AAH; frogs from lower tree density environments emit longer notes and have higher note rates than those from denser-tree environments. Subtle differences between Amazonian forest types can drive acoustic diversification of temporal and spectral features of calls at micro-evolutionary scales.","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47200511","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}

During spawning in the spring and summer, male silver perch produce distinctive knocking sounds to attract females. These sounds are readily identifiable through aural and visual analysis of underwater acoustic recordings, providing a means to track the distribution and spawning activity of these fish. However, as the volume of passive acoustic datasets grows, there is an essential need to automate the process of cataloguing silver perch vocalisations. The approach presented here utilises a (1) detection stage, where candidate calls are identified based on the properties of signal kurtosis and signal-to-noise ratio, (2) a feature extraction stage where layer activations are returned from the pre-trained ResNet-50 convolutional neural network operating on a wavelet scalogram of these signals, and (3) a one-vs-all support-vector-machine classifier. The labelled data used to build the classifier consists of 6000 perch calls and 6000 other signals that sample diverse acoustic conditions within the Pamlico Sound estuary, USA. The model accuracy is 98.9%, and the accompanying software provides an efficient tool to investigate silver perch calling patterns within passive acoustic data.","PeriodicalId":55385,"journal":{"name":"Bioacoustics-The International Journal of Animal Sound and Its Recording","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47670180","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 compared call structure and call parameters of syntopic species occurring together in the same locality within Singapore and found that syntopic congeners exhibit acoustic partitioning to avoid inter-specific competition for the acoustic space. We also found that calling songs can be highly varied among congeners and species from the same species groups.
