长江丽棘虫和黄颡异钩棘头虫单独在黄颡鱼肠中分布的相似性比例PS =0 684。它们共同寄生在黄颡鱼肠道内 ,长江丽棘虫的寄生部位向前移 ,黄颡异钩棘头虫的寄生部位明显向后移 ,生态位宽度变窄 ,生态位重叠值下降。但是 ,它们的平均感染强度并未降低 ,种间正关联显著
The similarity ratio of the distribution of L. catenella and C. heterophylla was only found in the intestine of C. mackerel PS = 0 684. They co-parasitized in the intestine of the yellow catfish, the parasites of Crabgrass were moved forward, the parasitic sites of C. hooker obviously moved backwards, the width of niche narrowed and the niche overlap decreased. However, their mean infection intensity did not decrease, and the interspecific association was significant
