Data from: The advertisement call of the toad Rhinella humboldti (Bufonidae)

Despite important advances in understanding phylogenetic relationships among anurans (Frost et al. 2006; Pyron & Wiens, 2011), many uncertainties persist regarding phylogenetic affinities and taxonomic limits. The male advertisement call offers numerous opportunities to find diagnostic characters and is therefore useful for anuran species delimitation (Gerhardt & Huber, 2002; Grant et al. 2006). Thirteen species are recognized within the Rhinella granulosa group (Narvaes & Rodrigues, 2009; Sanabria et al. 2010) although it is possible that R. dorbignyi and R. fernandezae being conspecifics (Guerra et al. 2011, page 36). The advertisement call has been described for nine species of the granulosa group: Rhinella granulosa, R. bergi, R. major, R. azarai, R. fernandezae, R. dorbignyi, R. merianae, R. centralis and R. pygmaea (Köhler et al. 1997; Guerra et al. 2011; São-Pedro et al. 2011; Ribeiro de Carvalho et al. 2013). Some information regarding call features are available for R. humboldti from populations of Guyana (Lescure & Marty, 2000); however, there are no associated data of male body size, sample size, and call traits such as pulse number per notes, note duration, etc. Here we provide a formal description of the advertisement call of R. humboldti using call recordings obtained in a population in Colombia, South America.

尽管学界在无尾两栖类（Anura）的系统发育关系研究上已取得重要进展（Frost等，2006；Pyron & Wiens，2011），但在系统发育亲缘关系与分类学界限方面仍存在诸多不确定性。雄性广告鸣声（male advertisement call）具备诸多可作为分类诊断的特征，因此在无尾两栖类的物种界定（species delimitation）中具有重要应用价值（Gerhardt & Huber，2002；Grant等，2006）。目前棱皮蟾属（Rhinella）粒突类群（Rhinella granulosa group）已被认可包含13个物种（Narvaes & Rodrigues，2009；Sanabria等，2010），但有研究指出R. dorbignyi与R. fernandezae可能为同一物种（Guerra等，2011，第36页）。目前已有9个粒突类群物种的广告鸣声被正式描述：Rhinella granulosa、R. bergi、R. major、R. azarai、R. fernandezae、R. dorbignyi、R. merianae、R. centralis及R. pygmaea（Köhler等，1997；Guerra等，2011；São-Pedro等，2011；Ribeiro de Carvalho等，2013）。目前已有来自圭亚那种群的R. humboldti的部分鸣声特征信息（Lescure & Marty，2000），但该研究未提供雄性个体体长、样本量以及每音节脉冲数（pulse number per notes）、音节时长（note duration）等相关鸣声参数数据。本研究基于采自南美洲哥伦比亚某种群的鸣声录音，对R. humboldti的广告鸣声进行正式描述。
