In species assemblages of larval trematodes in individual snail hosts, fewer multispecies
infections are observed than might be expected by chance. Both interspecific competition …

Review of the trematode genus Ribeiroia (Psilostomidae): ecology, life history, and
pathogenesis with special emphasis on the amphibian malformation problem Page 221 Review …

The first half of this book is primarily a systematic survey of the snails, beginning with
glossaries, keys for identification to genera and a checklist of species. This is followed by a …

The wide geographic distribution of Schistosoma mansoni, a digenetic trematode and
parasite of humans, is determined by the occurrence of its intermediate hosts, freshwater …

Spatial variation in parasitism is commonly observed in intermediate host populations.
However, the factors that determine the causes of this variation remain unclear. Increasing …

Descriptive analyses of parasite community structure are now available for a wide variety of
vertebrate hosts (see Chapters 1, 5, 6, 7, 8 and 9; see also Choe and Kim, 1987). Parasite …

The study of parasite communities has traditionally focussed on helminth communities in
vertebrate hosts. However, the literature reveals a substantial body of information which …

Freshwater and marine snails serve as intermediate hosts for numerous species of larval
trematodes. Any particular population of snails may be infected by several species. It is …

Paramphistomoids are ubiquitous and widespread digeneans that infect a diverse range of
definitive hosts, being particularly speciose in ruminants. We collected adult worms from …

Invasive non-native species are a major threat to global biodiversity. Often introduced
accidentally through international travel or trade, they invade and colonize new habitats …
