This study compared the monogeneans community in from the Tapajós River (state of Pará) and Jari River (state of Amapá), northern Brazil. A total of 2188 monogeneans belonging to eight taxa were collected from the gills of fish: , , , , , , and . was the dominant species for from the Tapajós River basin, while predominated among the hosts from the Jari River basin. For the two populations of , the prevalence, mean intensity and mean abundance of monogeneans were different and the of parasites community had a high qualitative similarity (87.5 %). The monogeneans community of was characterized by high species richness, with infection values varying from low to moderate. The geographic distance and differences in environmental characteristics arising from the same did not influence the richness of species of monogeneans infesting in the Tapajós and Jari rivers, but appear to have been determinants in the differences observed in the structure of the monogenean communities in each region.
本研究比较了巴西北部帕拉州塔帕若斯河和阿马帕州雅里河的单殖吸虫群落。从鱼类鳃部共采集到2188条属于8个分类单元的单殖吸虫：[此处原文缺失具体分类单元名称]。[此处原文缺失具体物种名称]是塔帕若斯河流域[此处原文缺失具体宿主名称]的优势种，而[此处原文缺失具体物种名称]在雅里河流域的宿主中占主导地位。对于[此处原文缺失具体宿主名称]的两个种群，单殖吸虫的感染率、平均感染强度和平均丰度不同，寄生虫群落的[此处原文缺失具体内容]具有较高的定性相似性（87.5%）。[此处原文缺失具体宿主名称]的单殖吸虫群落具有物种丰富度高的特点，感染值从低到中等不等。地理距离以及由此产生的环境特征差异并未影响塔帕若斯河和雅里河中感染[此处原文缺失具体宿主名称]的单殖吸虫物种丰富度，但似乎是每个区域单殖吸虫群落结构差异的决定因素。
