Variability of the body size in females of the Cosmocerca ornata (Dujardin, 1845), a parasite of marsh frogs, is studied. The influence of both biotic (age, sex and a phenotype of the host, density of the parasite population) and abiotic (a season of the year, water temperature) factors on the formation of the body size structure in the C. ornata hemipopulation (infrapopulation) is demonstrated. The body size structure of the C. ornata hemipopulation is characterized by the low level of individual variability as within certain subpopulation groups of amphibians (sex, age and phenotype), so within the population of marsh frogs as a whole. The more distinct are the differences in biology and ecology of these host subpopulations, the more pronounced is the variability in the body size of C ornata.
对沼泽蛙寄生虫华丽科斯莫线虫（杜雅尔丹，1845年）雌性个体的体型变异性进行了研究。研究表明，生物因素（年龄、性别、宿主表型、寄生虫种群密度）和非生物因素（一年中的季节、水温）均会对华丽科斯莫线虫半种群（感染种群）的体型结构形成产生影响。华丽科斯莫线虫半种群的体型结构特点是，在两栖动物的某些亚种群组（性别、年龄和表型）内以及整个沼泽蛙种群中，个体变异性水平较低。这些宿主亚种群在生物学和生态学上的差异越明显，华丽科斯莫线虫的体型变异性就越显著。
