Acoustic parameters of Phyllodytes luteolus in conditions of low and high noise from vehicle traffic

Acoustic communication in animals can be affected by multiple biotic (intra and interspecific) and abiotic (e.g., wind and rain) natural noises. In addition, human beings produce additional novel sources of noise, which can reduce or inhibit the reception of acoustic signals by conspecifics, leading to behavioral changes. In this study, we investigated whether sound of conspecifics and road noise additively affect the acoustic parameters of the advertisement call of males of a Yellow Heart-tongued Frog (Phyllodytes luteolus). We hypothesized that males that vocalize in larger choruses (many males) and in areas close to highways (anthropic noise) will increase their temporal and spectral acoustic parameters, respectively, to avoid acoustic signal masking. We recorded the vocalizations of 38 males in environments close (N=18) to and distant (N=20) from highways in different social contexts (many or few individuals in the chorus). Contrary to our expectation, the results indicated that ind..., Field activities were carried at five sampling sites in the municipality of Ilhéus, Bahia, Brazil. All areas have bromeliads used as reproductive sites by Phyllodytes luteolus. Three sites with the presence of vehicle traffic noise were located next to the BA-001 highway (between 3 and 10 meters away from the highway), in the stretches between Olivença and Acuípe villages, in the municipality of Ilhéus. The sampling sites were defined as Natural (no traffic noise) or Highways (with traffic noise). For each recorded individual, we obtained the social situation in which the male was inserted, being: with chorus (four or more conspecific individuals in vocalization activity within a three-meter radius – CC) or without chorus (four or less conspecific individuals vocalizing within a radius of three meters – SC). Males of Phyllodytes luteolus in vocalization activity were found through visual and auditory searches between 19:00 and 24:00 hrs. After viewing the male, the advertisement calls w..., , # Acoustic parameters of advertisement call Phyllodytes luteolus, and morphological and climatic values.

Give a brief summary of dataset contents, contextualized in experimental procedures and results.

## Description of the data and file structure

This open data comprises body size values, climatic and environmental variables. This primary data shows the acoustic parameters of the announcement song of a species of bromeliad anuran. Information on the natural history of this species of anuran is still scarce.

All the information needed to understand the variables and the values obtained is in the document and represented briefly here in this section.

动物的声学通讯可受到多种生物（种内与种间）以及非生物（如风、雨）自然噪声的影响。此外，人类活动产生的新型噪声会减少甚至抑制同种个体接收声学信号，进而引发行为改变。本研究旨在探究同种鸣声与道路噪声是否会共同影响黄心雨蛙（*Phyllodytes luteolus*）雄性个体的宣鸣声学参数。我们提出假说：当雄性个体处于更大的鸣唱群（较多雄性）中，或是在靠近高速公路的区域（人为噪声环境）时，会分别提升其鸣唱的时域与频域声学参数，以避免声学信号被掩蔽。我们在不同社会情境下（鸣唱群内个体较多或较少），于靠近（N=18）和远离（N=20）高速公路的生境中录制了38只雄性个体的鸣叫声。结果与我们的预期相悖，研究结果显示……。野外工作在巴西巴伊亚州伊列乌斯市的5个采样点开展，所有区域均存在被黄心雨蛙用作繁殖位点的凤梨科植物。其中3个紧邻BA-001高速公路（距公路3至10米）的采样点存在车辆交通噪声，路段位于伊列乌斯市奥利文萨村与阿库伊佩村之间。采样点被划分为自然组（无交通噪声）与公路组（存在交通噪声）两类。对于每一只录制的雄性个体，我们记录了其所处的社会情境：鸣唱群组（CC，即3米半径范围内有4只及以上同种个体处于鸣唱活动中）或非鸣唱群组（SC，即3米半径范围内有4只及以下同种个体处于鸣唱活动中）。研究人员在19:00至24:00时段通过目视与听觉搜寻找到处于鸣唱活动中的黄心雨蛙雄性个体。定位到雄性个体后，对其宣鸣进行录制……。
