Four new species of Cichlidogyrus (Platyhelminthes, Monopisthocotyla, Dactylogyridae) from Lake Victoria haplochromine cichlid fishes, with the redescription of C. bifurcatus and C. longipenis. [PDF]

open access: yesParasite
African cichlids are model systems for evolutionary studies and host-parasite interactions, because of their adaptive radiations and because they harbour many species of monogenean parasites with high host-specificity.

Spraints demonstrate small population size and reliance on fishponds for Eurasian otter (Lutra lutra) in Hong Kong

open access: yesConservation Science and Practice, Volume 5, Issue 1, January 2023., 2023
Eurasian otter (Lutra lutra) are declining widely across China and remain rare and virtually unstudied in Hong Kong. We intensively sampled spraints in the Mai Po wetlands across two years and through microsatellite genotyping identified seven individuals and a dominance of fish (97%) in their diet based on prey‐remains analysis.

Meta‐analysis of major histocompatibility complex (MHC) class IIA reveals polymorphism and positive selection in many vertebrate species

open access: yesMolecular Ecology, Volume 31, Issue 24, Page 6390-6406, December 2022., 2022
Abstract Pathogen‐mediated selection and sexual selection are important drivers of evolution. Both processes are known to target genes of the major histocompatibility complex (MHC), a gene family encoding cell‐surface proteins that display pathogen peptides to the immune system.
