摘要

olm(Proteus blogenius)是一种分布在欧洲迪纳利群岛地下水域的特有两栖动物,是世界上最广为人知的地下物种之一。尽管olm生物学的各个方面已经得到了广泛的研究,但关于它们在野外行为的数据仍然很少,主要是因为无法进入它们的自然栖息地。然而,olms也会在夜间出现在几个岩溶泉中。这些更容易获得,为研究olm在自然界中的行为提供了一个令人兴奋的机会。在这里,我们报告了在斯洛文尼亚的一个这样的春天对olms的系统观测,在那里我们连续九个夏夜对它们进行了观测,将直接现场观测与红外相机陷阱记录相结合。我们使用红外相机捕捉记录来构建简单的行为图,并通过视频跟踪来量化olm的运动活动。夜间,奥尔姆斯经常出现在地表上,黎明似乎是他们撤退到地下的关键刺激因素。它们总是很活跃,但很少游到离春天很远的地方。尽管这项研究的性质是短期的,但我们收集了新的事件和运动数据,同时测试了红外相机在调查olm在自然界中的存在和行为方面的可用性。通过研究获得的经验可能会促使使用类似方法进行长期和更复杂的行为研究。

Behavioral observations of the olm (Proteus anguinus) in a karst spring via direct observations and camera trapping
The olm (Proteus anguinus), an endemic amphibian of the Dinarides’ underground waters (Europe), is one of the world’s most widely known subterranean species. Although various aspects of olm biology have been extensively studied, the data on their behavior in the wild remain scarce mostly due to inaccessibility of their natural habitat. Yet, olms also occur in several karstic springs during nighttime. These are easier to access and present an exciting opportunity to study olm behavior in nature. Here, we report on systematic observations of olms in one such spring in Slovenia, where we observed them for nine consecutive summer nights, coupling direct on-site observations with IR camera trap recordings. We used IR camera trap recordings to construct simple ethograms, as well as to quantify olm movement activity by video-tracking. Olms regularly occurred on the surface during the night, and dawn appeared to be a key stimulus for their retreat underground. They were constantly active, but rarely swam far from the spring. Despite the short-term nature of the study, we collected new occurrence and movement data, and at the same time tested the usability of IR cameras for surveying olm presence and behavior in nature. Experience gained through the study may prompt long-term and more complex behavioral studies using similar approaches.

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.
