Abstract

Hyaena faeces and mineral licks represent highly concentrated nutrient resources for leopard tortoises (Stigmochelys pardalis) living in nutrient-poor environments. Here, we provide direct evidence for the consumption of hyaena faeces and artificial mineral licks by leopard tortoises in the Kalahari Desert. Tortoises aggregated at hyaena latrines and lick sites during the wet season between 10 AM and 6 PM in groups of 1–5 individuals. Where both salt and mineral licks were available, tortoises displayed a preference for salt. We suggest that calcium, phosphorus and sodium deficits are likely driving coprophagy and geophagy behaviours by tortoises in the Kalahari.

低营养环境中的豹纹陆龟（Stigmochelys pardalis）对鬣狗粪便和人工矿物质舔舐的食用情况

对于生活在营养不良环境中的豹纹陆龟（Stigmochelys pardalis）来说，鬣狗粪便和矿物质舔舐地是高度浓缩的营养资源。在这里，我们提供了卡拉哈里沙漠中豹龟食用鬣狗粪便和人工矿物质舔食地的直接证据。在雨季的上午 10 点到下午 6 点期间，龟以 1-5 只为一组聚集在鬣狗的厕所和舔食点。在既有盐舔食点又有矿物质舔食点的地方，陆龟表现出对盐的偏好。我们认为，钙、磷和钠的缺乏很可能是卡拉哈里陆龟共食和地食行为的驱动因素。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
