“…But anyway, these above results indicate the fact that domestic geese in China seem to have the low level of genetic diversity. Besides, Poyarkov et al (2010) focused on the maternal investigation on the swan goose breeds in Russia, and they found a similar low value of nucleotide diversity (Pi＝0.0074) in 48 geese from two groups nesting. Among them, in those from Khabarovsk Sun et al: Mitochondrial DNA D-loop Region in Geese krai region, nucleotide diversity of swan geese was only 0.0031.…”

In contrast to other farm animals, the matrilineal structure of domestic goose has remained an open question. In this study, we analyzed mitochondrial DNA control region sequence variation of 245 domestic geese to discern the main matrilineal components and their phylogenetic relationships. The result of phylogenetic analysis indicated the distinct lineage of clade II and the result of network analysis further suggested the major group of Chinese native goose breeds (subclade S) and introgressive goose breeds (subclade G). Except Yili geese, all Chinese domestic goose breeds were clustered in S, whereas clade II were widely distributed in 2 European breeds, Yili geese as well as 3 domestic Graylag geese. The results support that Chinese domestic goose breeds (except the Yili breed) originated from Swan goose (Anser cygnoides) while European goose breeds originated from Graylag goose (Anser anser). In total, 17 Landoise and 16 White Roman geese were clustered in subclade G together with 1 domestic goose (A. anser, AY112966), which supported the previous finding that European geese originated from Graylag goose (A. anser). But 9 unanticipated samples of two Chinese domestic goose breeds including 7 Lion-head geese and 1 Zhedong White goose in haplotype H9 were also clustered in subclade G as well as 3 Lion-head geese in haplotypes H13, H15 and H16 and 2 Zhedong White geese in haplotypes H18 and H19, which may be caused by the potential gene introgressions between swan goose breeds and graylag breeds with a directional contribution towards graylag geese.

“…Therefore, it is necessary to derive a more accurate core home range through continuous tracking of habitat use information in the future. Nevertheless, the information on the core home range estimated in this study can be valuable for protecting the Far East Russian population of Swan Goose, which has a significantly small number and exhibits genetic differentiation compared with the Chinese and Mongolian populations [ 12 , 13 , 15 ].…”

“…The global population has been estimated to be approximately 60,000–90,000 individuals, but the Far East Russian population is known to be less than 10% of the global population [ 10 , 11 ]. In addition, the Far East Russian population may have been genetically isolated from the Chinese and Mongolian populations [ 15 ]. Previous studies using neck-collar marking and telemetry tracking reported that the Far East Russian population commonly visits and uses two regions (the Han River Estuary and Seocheon Tidal Flat, South Korea) as wintering and stopover areas [ 13 , 16 ].…”

The Seocheon Tidal Flat is an important staging and wintering site for the Far East Russian population of Swan Goose (Anser cygnoides) in the East Asian–Australasian Flyway. However, rapid environmental changes for tourism in this area can threaten the survival of this vulnerable population by hindering sufficient rest and wintering; therefore, establishing protection strategies based on Swan Goose behavioral characteristics is necessary. Here, we estimated Swan Goose core home ranges and habitat use based on GPS tracking data collected at the Seocheon Tidal Flat in South Korea from 2017–2018. The home range of Swan Geese was estimated to be an area from Yubu Island in the south to Janggu Bay in the north; however, the core home range and habitat use characteristics differed significantly between daytime and nighttime (Day: 59.9 km2, Night: 40.3 km2, on average, 100% MCP). During the day (08:00–18:00), Swan Geese mostly spent time resting or feeding on tidal flats, especially those around tidal channels or paddy fields near Janggu Bay, whereas they mostly rested on sand dunes near Yubu Island along with the mudflats at Janggu Bay at night. Our results provide practical information on the habitat use of wintering Swan Geese population over time and indicate that Yubu Island is an important resting place. Hence, these results can contribute to evaluating threats to Swan Geese and establishing management and protection strategies for the Seocheon Tidal Flat, a major wintering site for the Far East Russian population of Swan Geese.

Lack of conspicuous sex‐biased dispersal patterns at different spatial scales in an Asian endemic goose species breeding in unpredictable steppe wetlands

Dispersal affects the spatial distribution and population structure of species. Dispersal is often male‐biased in mammals while female‐biased in birds, with the notable exception of the Anatidae. In this study, we tested genetic evidence for sex‐biased dispersal (SBD) in the Swan Goose Anser cygnoides , an Asian endemic and IUCN vulnerable species, which has been increasingly restricted to breeding on Mongolian steppe wetlands. We analyzed the genotypes of 278 Swan Geese samples from 14 locations at 14 microsatellite loci. Results from assignment indices, analysis of molecular variance, and five other population descriptors all failed to support significant SBD signals for the Swan Goose at the landscape level. Although overall results showed significantly high relatedness within colonies (suggesting high levels of philopatry in both sexes), local male genetic structure at the 1,050 km distance indicated greater dispersal distance for females from the eastern sector of the breeding range. Hence, local dispersal is likely scale‐dependent and female‐biased within the eastern breeding range. These findings are intriguing considering the prevailing expectation for there to be female fidelity in most goose species. We suggest that while behavior‐related traits may have facilitated the local genetic structure for the Swan Goose, several extrinsic factors, including the decreasing availability of the nesting sites and the severe fragmentation of breeding habitats, could have contributed to the absence of SBD at the landscape level. The long‐distance molt migration that is typical of goose species such as the Swan Goose may also have hampered our ability to detect SBD. Hence, we urge further genetic sampling from other areas in summer to extend our results, complemented by field observations to confirm our DNA analysis conclusions about sex‐specific dispersal patterns at different spatial scales in this species.
