ABSTRACT The parasitic nematode communities are described from the oesophagi and stomachs of eastern grey kangaroos, Macropus giganteus (Shaw), red-necked wallabies, Notamacropus rufogriseus (Desmarest) and swamp wallabies, Wallabia bicolor (Desmarest) (Marsupialia: Macropodidae) from coastal and montane habitats in southeastern New South Wales. The number of nematode species recorded for each macropodid species was similar to that recorded in previous studies in Victoria. Overall diversity of nematode communities was greatest in N. rufogriseus and greater in montane than in coastal localities in both N. rufogriseus and M. giganteus. Community similarity between coastal and montane localities was highest in N. rufogriseus compared to M. giganteus and W. bicolor. Few nematode species were shared between host species. There were more significant differences in species prevalences than intensities of infection in M. giganteus between coastal and montane localities, less so for N. rufogriseus but these were not calculated for W. bicolor due to small montane sample size. Community differences between macropodid species were attributable primarily to host-specific parasite species. This is the first comparison of helminth communities in macropodids in a replicated study in different habitats at similar latitudes.

新南威尔士州东南部沿海和山地环境中三种同域巨足类动物的食道和胃线虫群落

摘要 从东部灰袋鼠的食道和胃中描述了寄生线虫群落，Macropus giganteus (Shaw)、红颈小袋鼠、Notamacropus rufogriseus (Desmarest) 和沼泽小袋鼠、双色袋鼠 (Desmarest)：Marsupialia新南威尔士州东南部的山地栖息地。每个巨足类动物记录的线虫种类数量与维多利亚之前的研究记录的数量相似。N. rufogriseus 线虫群落的总体多样性在 N. rufogriseus 和 M. giganteus 中最大，在山地比沿海地区更大。与 M. giganteus 和 W. bicolor 相比，N. rufogriseus 的沿海和山地地区之间的群落相似性最高。宿主物种之间共享的线虫物种很少。沿海和山地地区之间的 M. giganteus 的物种流行率差异比感染强度更显着，N. rufogriseus 的差异较小，但由于山地样本量较小，因此未对双色 W.进行计算。巨足动物物种之间的群落差异主要归因于宿主特定的寄生虫物种。这是在相似纬度的不同栖息地的重复研究中对巨足类蠕虫群落的首次比较。
