Abstract

Although predatory events are uncommon to be recorded in nature, these data are important tools for understanding prey-predator interaction of the involved species. Snakes of genus Thamnodynastes are known for having an anuran diet, including some species of hylid frogs in their diet. Despite this, this pattern does not include T. chaquensis since there are no records on predation or trophic interaction with hylid frogs.Here, we report the first predatory interaction between T. chaquensis and two hylid frogs in Brazilian Cerrado. The first predation event with treefrog Boana caiapo occurred with success but, the second with B. albopunctatadid not. Connecting trophic links within an ecosystem requires in-depth knowledge of its species and their intraspecific interactions. In this context, records of the predation and predation attempts such as these may help to connect unknown trophic links, which helps to understand aspects of the natural history of the species involved.

巴西塞拉多地区两种无尾蝇与沙斑蝶的掠食性相互作用

虽然在自然界中记录的掠食性事件并不多见，但这些数据是了解相关物种的捕食者-猎物相互作用的重要工具。Thamnodynastes属的蛇以无性饮食而闻名，其中包括一些种类的水螅蛙。尽管如此，这种模式不包括T. chaquensis，因为没有关于捕食或与水螅蛙营养相互作用的记录。本文报道了巴西塞拉多地区首次发生的查克蛙与两种水蛙的掠食性相互作用。第一次捕食成功了，而第二次捕食失败了。连接生态系统内的营养联系需要对其物种及其种内相互作用有深入的了解。在这种情况下，诸如此类的捕食和捕食企图的记录可能有助于连接未知的营养联系，这有助于了解有关物种的自然历史方面。

期刊介绍： Bothalia: African Biodiversity & Conservation is published by AOSIS for the South African National Biodiversity Institute (SANBI) and aims to disseminate knowledge, information and innovative approaches that promote and enhance the wise use and management of biodiversity in order to sustain the systems and species that support and benefit the people of Africa. The journal was previously published as Bothalia, and had served the South African botanical community since 1921. However the expanded mandate of SANBI necessitated a broader scope for the journal, and in 2014, the subtitle, African Biodiversity & Conservation was added to reflect this change.
