Machine learning models accurately predict clades of proteocephalidean tapeworms (Onchoproteocephalidea) based on host and biogeographical data

Cladistics, Volume 41, Issue 3, Page 264-282, June 2025.
Abstract Proteocephalids are a cosmopolitan and diverse group of tapeworms (Cestoda) that have colonized vertebrate hosts in freshwater and terrestrial environments. Despite the ubiquity of the group, key macroevolutionary processes that have driven the group's evolution have yet to be identified.

A revision of the genus Astatoreochromis (Teleostei, Cichlidae), East–Africa

European Journal of Taxonomy, 2013
A taxonomic revision of the cichlid genus Astatoreochromis is presented. Eighteen meristic and 23 morphometric measurements were taken on 185 individuals, including type specimens. While fin counts separate populations from the Lake Victoria region (Astatoreochromis alluaudi) from those of the Rusizi and Malagarazi rivers in the Lake Tanganyika basin ...

Megalocytivirus: A Review of Epidemiology, Pathogenicity, Immune Evasion, and Prevention Strategies

Reviews in Aquaculture, Volume 17, Issue 3, June 2025.
ABSTRACT Megalocytivirus, a large double‐stranded DNA virus belonging to the Iridoviridae family, has infected over 100 species of fish, leading to significant economic losses in the aquaculture, food, and ornamental fish industries. These viruses exhibit icosahedral symmetry and have diameters ranging from 120 to 200 nm.

Possible Involvement of Ghost Introgressions in the Striking Diversity of Vomeronasal Type 1 Receptor Genes in East African Cichlids

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Possible involvement of ghost introgressions as a source of V1R diversity in cichlids. ABSTRACT Cichlids that have undergone adaptive radiation are genetically close but exhibit extreme ecological and morphological diversity, making them useful for understanding speciation mechanisms.

Global Patterns and Drivers of Freshwater Fish Extinctions: Can We Learn From Our Losses?

Global Change Biology, Volume 31, Issue 5, May 2025.
Nearly one‐third of freshwater fish species are currently at risk of extinction, with 100 species already lost. This study examines extinction patterns over the past 165 years, identifying habitat modification and loss, pollution, and invasive species as key drivers.

Trophic Plasticity of the Invasive Redbelly Tilapia (Coptodon zillii) in China Inferred From DNA Metabarcoding Analysis

Ecology and Evolution, Volume 15, Issue 4, April 2025.
The feeding patterns of invasive populations of C. zillii in different habitats and seasons within a large‐scale geographic area (spanning 9.86° latitude and 10.47° longitude) in China were directly compared. ABSTRACT The redbelly tilapia (Coptodon zillii) is one of the most dangerous invasive alien fishes in the world.
