Helminth diversity in brine shrimps () from Ukraine.

Brine shrimps ( spp.) are aquatic crustaceans known as important intermediate hosts for a wide range of helminth species. From 2011 to 2021, 4,347 individuals of brine shrimp were collected for this study, investigating the diversity and infection rates of helminth species in spp.

Helminth Parasites of Invasive Freshwater Fish in Lithuania.

Freshwater ecosystems in Lithuania are threatened by the introduction of invasive fish species including , , , and . Data on helminth parasites of these fishes have not been comprehensively studied, with only two reports on parasites of from the Curonian Lagoon and Baltic Sea, Lithuania. We examined 278 fish individuals representing 4 invasive species from 13 waterbodies.

Trematode species diversity in the faucet snail, at the western edge of its native distribution, in Ireland.

Trematodes and their snail hosts have developed intimate parasite-host associations, with snails supporting a diverse and often species-specific trematode fauna. In the faucet snail, (Caenogastropoda, Littorinimorpha), a unique trematode fauna has been recorded recently. However, knowledge of the exact species identity, phylogenetic relationships, and geographical distribution remains limited as many of the species belong to groups with unclear or controversial taxonomical assignment.

Discovering high species diversity of tapeworms (Cestoda: Proteocephalidae) of watersnakes (Colubridae) in North America.

Tapeworms of the genus La Rue, 1911 parasitize herptiles (= amphibians and 'reptiles') throughout the world, with about 100 species recognised as valid. In the present work, the North American species found in watersnakes (Colubridae) are reviewed. An examination of the holotype of La Rue, 1911, the type species of the genus, and other specimens from (Hallowell) revealed that two species were used for the species description.
