Abstract Due to anthropogenic mechanisms, global freshwater biodiversity is declining, and non‐indigenous species are consistently cited as a major threat to native ecosystems. In particular, exotic freshwater gastropods and their parasites have invaded ecosystems through deliberate introductions and/or accidental transfer.

Cepaea spp. as a source of Brachylaima mesostoma (Digenea: Brachylaimidae) and Brachylecithum sp. (Digenea: Dicrocoeliidae) larvae in Poland [PDF]
AbstractParasite diagnostics were carried out on 11 Polish populations ofCepaeaspp. In three of them, coming from the roadside ditches of a village (Rytel, northern Poland), very high (up to 60%) prevalence ofBrachylaima mesostomawas observed. This study provides the first molecular evidence of the presence ofB. mesostomainsideCepaeaspp. in Europe.

Abstract We explored whether parasites are important in kelp forests by examining their effects on a high‐quality, high‐resolution kelp‐forest food web. After controlling for generic effects of network size, parasites affected kelp‐forest food web structure in some ways consistent with other systems.

No Tail No Fail: Life Cycles of the Zoogonidae (Digenea)
The Zoogonidae is the only digenean family where known cercariae lack the tail but actively search for the second intermediate host. However, the data on the zoogonid life cycles are scarce. In the present study, we elucidated and verified life cycles of the Zoogonidae from the White Sea.

Modifications of Prenyl Side Chains in Natural Product Biosynthesis
This review summarizes the unique modifications of prenyl side chains involved in natural product biosynthesis, including epoxidation, dehydrogenation, oxidation of methyl groups to carboxyl groups, C−C bond cleavage and oxidative cyclization. Abstract In recent years, there has been a growing interest in understanding the enzymatic machinery ...

Characterization of Clinostomum (Digenea: Clinostomidae) spp. in India
Abstract Platyhelminths belonging to the family Clinostomidae (Digenea) have a worldwide distribution and are known to infect piscivorous birds through their intermediate hosts, usually fish species. In the present study, clinostome metacercariae were collected from fish hosts, including Channa punctata (Bloch 1793) (n = 25) and Trichogaster fasciata ...
