Abstract

Existing studies on central Chilean inland waters only mention records of decapods, but there are no ecological studies about decapods and other crustacean groups. The aim of the present study was a first characterization of inland water crustaceans in Claro River, a Mediterranean-climate river from Chile. The results of redundance analysis (RDA) revealed that the crab Aegla affinis inhabits waters of high pH and low temperature values, whereas amphipods of the genus Hyalella inhabit habitats with high pH, high temperatures, and low values of dissolved oxygen. Finally, ostracods (family Cyprididae), isopods (Heterias sp.) and the southern river crayfish (Samastacus spinifrons) inhabit water systems with moderate values of pH, temperature, dissolved oxygen, and conductivity. This paper represents the first ecological report for crustaceans of central Chilean inland waters, and the results appear to be similar to comparable descriptions for northern Patagonian rivers.

首次报告地中海气候河流（智利克拉罗河流域）的内陆水域底栖甲壳类动物

关于智利中部内陆水域的现有研究只提到了十足目动物的记录，但没有关于十足目动物和其他甲壳类动物的生态学研究。本研究的目的是首次描述智利地中海气候河流克拉罗河（Claro River）内陆水域甲壳类动物的特征。冗余分析（RDA）结果表明，蟹类 Aegla affinis 栖息于 pH 值高、温度值低的水域，而片脚类 Hyalella 属栖息于 pH 值高、温度高、溶氧值低的生境。最后，桡足类（鲤形目）、等足类（Heterias sp.）和南方河螯虾（Samastacus spinifrons）栖息在 pH 值、温度、溶解氧和电导率适中的水系中。本文是智利中部内陆水域甲壳类动物的第一份生态报告，其结果似乎与巴塔哥尼亚北部河流的类似描述相似。

期刊介绍： Crustaceana is a leading journal in the world on crustacean research, including the latest papers from all branches of zoology. It provides up-to-date information on aspects such as taxonomy, zoogeography, ecology, physiology, anatomy, genetics, palaeontology, and biometry, and covers all groups of Crustacea. Boasting a large international circulation, Crustaceana provides its readers with an abstract for each article.
