Ecology of helminth communities in tropical Australian amphibians

Less than 50% of Australian amphibians have been recorded as hosts for helminth parasites. Despite developments in parasite community ecology in amphibians elsewhere, Australia lags behind with only two publications on this subject. Reasons advanced for this are that much of the collecting and taxonomic studies were conducted earlier this century before more recent discoveries of host genera and species as well as species complexes in the amphibian fauna. Consequently, there is a need for re-collection of hosts and parasites, and taxonomic revision of the parasites. In addition, as shown in this study, the parasite fauna in Australian amphibians is depauperate. Composition of the parasite fauna was largely dependent on the ecological associations of the host animal species. Frogs were infected with few helminth species and these occurred at low intensity, indicating, as in Europe and North America, that a depauperate fauna is also characteristic of amphibians in tropical regions.
