Diversity of Plagiorchis (Trematoda: Digenea) in high latitudes: Species composition and snail host spectrum revealed by integrative taxonomy
Parasites are important components of ecosystems, thus identifying patterns of their diversity is crucial for studies investigating ecosystem functioning, food web structure, trophic interactions and epidemiological parameters.

Parasites are important components of ecosystems, thus identifying patterns of their diversity is crucial for studies investigating ecosystem functioning, food web structure, trophic interactions and epidemiological parameters. Via an integrative taxonomic approach, we studied the diversity and distribution of trematodes of the genus Plagiorchis Lühe, 1899 in snails in the sub-Arctic freshwater ecosystems of Iceland and for comparative purposes in West and North Europe (Ireland and Finland, respectively), supplemented by data from Alaska, USA, all regions with remarkably few data on trematode diversity.
