The distribution among size and reproductive classes of the digenean Lankatrematoides gardneri was recorded from the pancreatic ducts of 41 dugongs from the Gulf of Papua, Papua New Guinea. Infrapopulation sizes ranged from 5 to 921 worms and showed no correlation with host age, sex, or month of capture. Immature worms tended to be concentrated in intermediate size classes, the largest immatures being no more numerous than matures. The mean proportion of mature worms in the 29 infrapopulations containing them was small (9.8%). Mature worms were significantly greater in mass than the largest immatures. There is evidence of an interaction between the presence or absence of mature worms and the distribution of immatures among classes.
在巴布亚新几内亚巴布亚湾的41头儒艮的胰管中记录了加德纳兰卡吸虫在大小和繁殖类别的分布情况。虫口数量从5条到921条不等，与宿主的年龄、性别或捕获月份均无相关性。未成熟的虫体倾向于集中在中等大小类别中，最大的未成熟虫体数量并不比成熟虫体多。在包含成熟虫体的29个虫口群体中，成熟虫体的平均比例较小（9.8%）。成熟虫体的质量明显大于最大的未成熟虫体。有证据表明成熟虫体的有无与未成熟虫体在类别中的分布之间存在相互作用。
