Article Abstract
Guangdong province has diverse local goose breeds with unique characteristics, but there is limited research on their genetic diversity, formation history and breed-specific genes. This study uses whole-genome sequencing to analyze 120 local geese representing four officially recognized breeds and two lines of the folk breed Sanzhou Black goose, as well as five museum goose samples in the region, combined with 56 geese whole genome data from NCBI, with the aim of understanding the genetic diversity and relationships of Guangdong geese, identifying the history of breed formation, and discovering genes linked to various traits in these geese. The results show a considerable degree of genetic diversity in Guangdong local geese. The museum Sanzhou Black goose exhibit multiple ancestral components, and the Magang goose may be derived from the Sanzhou Black goose. A multitude of genes have been identified as related to various functional phenotypes in different Guangdong geese, such as fat deposition (ACER3), feather color (ACTA2), skin pigmentation (GDA), and body growth and development (ARHGAP21), collectively defining the distinctive attributes of indigenous breeds. These results provide a way to study the history of breed formation and a basis for selective breeding or utilization targeting goose breeds in Guangdong.

Shitou goose (STE) and Wuzong goose (WZE) are both characteristic goose breeds in Guangdong, China. Their growth cycle is similar, but there are huge differences in body size. One of the reasons for the difference in body size is the individual muscle mass, which is determined by myofiber development.

Migratory flyways sustain waterbird populations by linking critical habitats across their annual cycle. However, stage-specific impacts of climate change on these habitats remain poorly understood. We integrated species distribution models with annual migration data from 30 Greater White-fronted Geese () to assess changes in habitat suitability, distributional shifts, and suitability fluctuations across breeding, stopover, and wintering stages under mid-century (2040-2060) climate scenarios.

While transposable elements (TE) are critical drivers of genomic diversity, their influence on phenotypic traits in geese remain largely unexplored, primarily because most research has focused on single nucleotide polymorphisms (SNP). In this study, we identified 157,044 TE absence polymorphisms (TAP) in the genome of 566 Sichuan White geese through whole-genome resequencing (with an average coverage depth of 12.44 ×) to evaluate their influence across different populations, and we extended our investigation to include a TE genome-wide association study (TE-GWAS) encompassing 48 traits, with a particular focus on abdominal fat weight.

Birds generally rely on proactive anti-predator strategies when selecting nest sites, as they have limited options to adapt to changing levels of risk once incubation begins. Arctic waterfowl often nest colonially as an anti-predator strategy, but dispersed-breeding species may use other proactive strategies, such as nesting in areas perceived to be safer. However, empirical links between spatial patterns of predation risk and nest habitat selection or success are needed to better understand how predator activity shapes Arctic waterfowl reproduction.

Bee pollen is rich in nutrients and bioactive compounds, exhibiting properties such as antioxidant effects, immune enhancement, and promotion of growth and development. However, there are limited studies on the use of bee pollen in goose breeding. This study aimed to investigate the effects of rape bee pollen (RBP) and camellia bee pollen (CBP) on production performance, intestinal morphology, digestive enzyme activity, antioxidant and immune indices, and gut microbiota in Wanxi white goose.
