Competitive relations between protostrongylid nematodes parasitic in the ovine lung, using competition coefficients and asymptotic densities showed that two relatively scarce species (Neostrongylus linearis and Protostrongylus rufescens) exert strong competitive actions on the two most abundant species (Cystocaulus ocreatus and Muellerius capillaris). P. rufescens could lead to the disappearance of the more abundant species, if other compensatory factors did not exist in their life cycle.
利用竞争系数和渐近密度对寄生于绵羊肺部的原圆线虫之间的竞争关系进行研究，结果表明，两种相对稀少的线虫物种（线状新圆线虫和红原圆线虫）对两种数量最多的线虫物种（有囊尾泡线虫和毛细缪勒线虫）具有强烈的竞争作用。如果在它们的生命周期中不存在其他补偿因素，红原圆线虫可能会导致数量较多的物种消失。
