Abstract

A total of 140 trout were examined from four lakes in north west Ireland, Loughs Craghy, Waskel, Meela and Owennamarve. Eleven species of metazoan parasite were recorded, ten of which were of freshwater origin and Anisakissp. was the only marine species. No acanthocephalan species were found. Diphyllobothrium ditremum, D. dendriticum and Anisakissp. were the only allogenic species. Lough Owennamarve had the largest component community with nine species recorded. Lough Meela, the only brackish water lake had the smallest component community with six species recorded. Lough Waskel and Craghy had intermediate component community values. Lough Meela showed the lowest levels of similarity to any of the other lakes. Values for the Shannon-Wiener diversity index were highest for Lough Owennamarve and lowest for Lough Meela and intermediate for the other two lakes. Lough Meela had the highest values for the Simpson's dominance index and the Berger-Parker index. Lough Owennamarve had the highest Brillouin's index and Lough Meela had the lowest. The use of multiple regression techniques to control for the potentially confounding effect of geographical distance as a predictor of community similarity was discussed. No parasite species found could be considered as regionally and locally abundant and therefore described as a core species. The helminth community appears to have some degree of predictability, but chance colonization events are also important.

爱尔兰四个湖泊寄生虫群落的相似性

对爱尔兰西北部四个湖泊（克拉吉湖、瓦斯克尔湖、米拉湖和欧文纳马夫湖）中的 140 条鳟鱼进行了检测。共记录到 11 种元寄生虫，其中 10 种来自淡水，Anisakissp. 是唯一的海洋寄生虫。没有发现棘头蚴物种。Diphyllobothrium ditremum、D. dendriticum 和 Anisakissp.是唯一的异源物种。欧文纳马湖（Lough Owennamarve）拥有最大的生物群落，记录了 9 个物种。唯一的咸水湖米拉湖的群落组成最小，记录了 6 个物种。瓦斯凯尔湖和克拉吉湖的群落成分值居中。米拉湖与其他湖泊的相似度最低。欧文纳马湖（Lough Owennamarve）的香农-维纳（Shannon-Wiener）多样性指数值最高，米拉湖（Lough Meela）最低，其他两个湖居中。米拉湖的辛普森优势指数和伯杰-帕克指数值最高。欧文纳马湖的布里渊指数最高，米拉湖最低。讨论了使用多元回归技术来控制地理距离作为群落相似性预测因子可能产生的混杂影响。所发现的寄生虫物种中，没有一种可被视为区域性和地方性的丰富物种，因此被描述为核心物种。蠕虫群落似乎具有一定程度的可预测性，但偶然的定殖事件也很重要。

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.
