摘要

有尾类动物的行为和繁殖主要以发声为主,因此很容易受到信号掩蔽的影响。对于在动物园和水族馆展出的无尾类动物来说,环境噪声的一个主要来源是游客,这构成了潜在人为信号掩蔽的一个独特来源。研究人员在游客相关噪声增加的时段(水族馆闭馆时段、非高峰时段和高峰时段)对公开展示的三个石斛类种群(Dendrobates leucomelas、Epipedobates tricolor和Ranitomeya imitator)的叫声特征(总叫声持续时间、最小和最大叫声频率)进行了调查,以确定叫声特征的变化是否与游客噪声水平的变化相关。数据显示,随着游客噪音的增加,D. leucomelas 和 E. tricolor 的叫声长度也会增加,高峰时段的叫声最长,而在闭馆时段,所有三个物种的叫声都最短。随着游客噪音的增加,E. tricolor和R. imitator的最低和最高叫声频率都会增加,高峰时段的频率最高,而闭馆时段的频率最低。这项研究发现,有证据表明,在公共场合展示的无尾熊类动物会在游客噪音的影响下调整它们的叫声。这些研究结果支持扩大对公开展示动物的环境噪声监测,以确定噪声是否会对动物的健康或繁殖造成重大影响。

The effects of anthropogenic noise on frogs housed on exhibit at a public aquarium.

The effects of anthropogenic noise on frogs housed on exhibit at a public aquarium.

Anuran behavior and reproduction are dominated by vocalizations, rendering them vulnerable to the effects of signal masking. For anurans on display in zoos and aquaria, a major source of ambient noise is visitors, which pose a unique source of potential anthropogenic signal masking. Call characteristics (total call duration, and minimum and maximum call frequencies) of three populations of dendrobatids (Dendrobates leucomelas, Epipedobates tricolor, and Ranitomeya imitator) on public display were investigated at time periods of increasing visitor-related noise (closed, off-peak, and peak aquarium visiting hours) to determine if there were changes in call characteristics that correlated with changes in visitor noise levels. The data revealed that call length increased with more visitor noise for D. leucomelas and E. tricolor, with their longest calls during peak hours, and all three species had their shortest calls during closed hours. Both minimum and maximum call frequencies increased with more visitor noise for E. tricolor and R. imitator, with their highest frequencies during peak hours, and lowest frequencies during closed hours. This study found evidence that anurans on public display adjust their vocalizations in the presence of visitor noise. These findings support expanded monitoring of ambient noise for animals on public display to determine if noise poses significant effects that might influence well-being or reproduction.

期刊介绍: Zoo Biology is concerned with reproduction, demographics, genetics, behavior, medicine, husbandry, nutrition, conservation and all empirical aspects of the exhibition and maintenance of wild animals in wildlife parks, zoos, and aquariums. This diverse journal offers a forum for effectively communicating scientific findings, original ideas, and critical thinking related to the role of wildlife collections and their unique contribution to conservation.
