We present the phylogeny, receptor binding property, growth in mammal cells and pathogenicity in mammal model of H3N8 viruses, which were isolated from wild birds in China. The human receptor preference and efficient replication in mice without prior adaption highlight that the H3N8 virus possesses the public threat potential.

With the continued spread of highly pathogenic avian influenza (HPAI), understanding the complex dynamics of virus transfer at the wild - agriculture interface is paramount. Spillover events (i.e.

(γ-CoV) primarily infects poultry, wild birds, and marine mammals. The widespread distribution and circulation of γ-CoV in the ecological environment may lead to sustained transmission and economic loss. To better understand the diversity of γ-CoV in wild birds, we collected 482 wild-bird faecal samples from Yunnan, encompassing 14 bird species.

Natal dispersal is a key process in ecology and evolution. Similarities of dispersal patterns between relatives can lead to small-scale kin structure within populations with consequences for population dynamics and genetics. Most studies have focused on birds, lizards, and small mammals.

In zebra finches and other birds, males are the homogametic sex (ZZ) while females are heterogametic (ZW), and females are distinguished by the presence of specific sequences on the female-specific W chromosome. However, when only a single W locus is analyzed, lack of a PCR product in a sample could potentially arise from genetic variation or technical failure of the amplification, leading to false identification of female samples as males.

Ligulosis is an important parasitic disease of freshwater fish, causing serious economic losses in the fisheries industry. In this study, we report the distribution of Ligula pavlovskii in avian definitive hosts in Türkiye and the first genetically confirmed presence of this species in Podiceps cristatus (great crested grebe). To achieve this, the mitochondrial cox1 gene region was used for molecular characterization and phylogenetic assessment.
