Abstract

We explore the population of the troglophilic harvestman Ischyropsalis ravasinii inhabiting the Buso del Valon ice cave located in the Italian Prealps. Spatial and temporal distributions of the specimens are investigated in relation to the variation of environmental abiotic conditions in the cave, such as the seasonal temperature and substrate surface typology. Our results show that I. ravasinii is distributed unevenly in the cave, most of individuals being present in the scree-covered section of the cave with superficial activities limited to the warm seasons only. In addition, our data suggests that the presence of a thick layer of rocky debris, together with high humidity and cold temperatures, are important limiting factors for the species. Seven additional species of harvestman are recorded in the cave, including the congeneric troglophilic species Ischyropsalis strandi. This is the first known record of these two troglophilic Ischyropsalis species coexisting within the same cave. An updated map of the distribution of I. ravasinii and I. strandi in the Italian Prealps is provided.
Seasonal意大利东部地区Buso del Valon冰洞穴居动物Ischyropsalis ravasinii(蛛形纲,蛛形纲,Ischyropsalididae)丰度及时空分布
我们研究了居住在意大利普雷阿尔卑斯山脉Buso del Valon冰洞的嗜人收割人Ischyropsalis ravasinii的种群。研究了样品的时空分布与季节温度和底物表面类型等环境非生物条件变化的关系。结果表明,拉瓦西尼在洞内分布不均匀,大部分个体分布在洞穴的覆盖层,仅在暖季活动。此外,我们的数据表明,一层厚厚的岩石碎片的存在,加上高湿度和低温,是该物种的重要限制因素。在该洞穴中还记录了另外7种收割机,包括同属的亲人类物种Ischyropsalis strandi。这是已知的第一个记录,这两个类人猿在同一个洞穴中共存。提供了意大利普雷阿尔卑斯地区I. ravasinii和I. strandi的最新分布图。

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.
