Conservation genetics of barbel species (Teleostei, Cyprinidae) facing hybridization and introgression along an elevational gradient in protected areas of northern Italy

Zoologica Scripta, Volume 54, Issue 1, Page 1-16, January 2025.
Abstract The European endemic barbels represent important bioindicators of river quality and are nowadays threatened by changing environmental conditions and hybridization with the invasive alien Barbus barbus. It is therefore fundamental to investigate interactions among species and adaptability to climate changes in protected areas of Northern ...

Generic Revision of the Southeast and East Asian Torrent Carp Subfamily Acrossocheilinae (Pisces: Teleostei) With Description of Three New Genera and a New Species From Vietnam

Journal of Zoological Systematics and Evolutionary Research, Volume 2025, Issue 1, 2025.
Molecular data from 35 of the 50 Acrossocheilinae species suggest that the species‐level diversity in the subfamily has been overestimated, likely due to inadequate taxon and geographic sampling and reliance on morphological characters that vary intraspecifically. Three new genera, one resurrected genus, two resurrected species, and one new species are

Unclear host taxonomy hinders parasite studies: An up‐to‐date checklist of the protozoan and metazoan parasites of Phoxinus minnows (Teleostei: Leuciscidae)

Journal of Fish Biology, Volume 105, Issue 6, Page 1501-1539, December 2024.
Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...
