Abstract
Abstract. This study presents the description of the advertisement call and a second call type of Scinax dolloi, recorded at its type locality, Vila de Maringá, Itatiaia, in the State of Rio de Janeiro, southeastern Brazil. The advertisement call consists of a multi-pulsed note showing upward modulation in the initial pulses. The second call type is usually emitted between advertisement call notes and consists of a modified version of the advertisement call with juxtaposition of the pulses that form the note in its structure. The advertisement call pulse rate, number of pulses and note duration best differentiate Scinax dolloi, S. hayii, and S. perereca. Despite some overlap in the spectral components (frequency range and dominant frequency), the three species present significantly different means.
巴西里约热内卢Itatiaia Vila de Maringá的斑点蛙（Anura，Hylidae）的发声，包括与形态相似物种的生物声学比较
摘要本研究介绍了在巴西东南部里约热内卢州，意大利的Vila de maring，其类型地点记录的sinax dolloi的广告呼叫和第二种呼叫类型的描述。通告调用由显示初始脉冲向上调制的多脉冲音符组成。第二种呼叫类型通常在广告呼叫音符之间发出，由广告呼叫的修改版本和在其结构中形成音符的脉冲并置组成。广告呼叫脉冲率、脉冲数和音符持续时间是区分花椒、海参和花椒的最佳指标。尽管在频谱成分(频率范围和优势频率)上有一些重叠，但这三个物种表现出明显不同的均值。
