Abstract:
Lesser White-fronted Goose Anser erythropus is recognized as a globally threatened species. Very small numbers stage and winter in Japan, mostly individually, as families or sometimes in small flocks. Since beginning to observe this species in 2001 at Sarobetsu, northern Hokkaido, Japan, we have noted increasing numbers. The increase, from a few individuals (2001–2004) to flocks (2005–2007), is of interest, given the threatened status of this species. Lesser White-fronted Goose now regularly migrates through Sarobetsu, giving us opportunities to observe this relatively rare winter visitor to Japan. In order to help clarify the status of this threatened species in Japan, we describe and discuss the change in numbers, the proportion of juveniles in flocks, family size and length of stay.

Abstract:
Many captive stocks of economically or otherwise valuable species were established before the decline of the wild population. These stocks are potentially valuable sources of genetic variability, but their taxonomic identity and actual value is often uncertain. We studied the genetics of captive stocks of the threatened lesser white-fronted goose Anser erythropus maintained in Sweden and elsewhere in Europe. Analyses of mtDNA and nuclear microsatellite markers revealed that 36% of the individuals had a hybrid ancestry. Because the parental species are closely related it is unlikely that our analyses detected all hybrid individuals in the material. Because no ancestral polymorphism or introgression was observed in samples of wild populations, it is likely that the observed hybridisation has occurred in captivity. As a consequence of founder effect, drift and hybridisation, captive stocks were genetically differentiated from the wild populations of the lesser white-fronted goose. The high level of genetic diversity in the captive stocks is explained at least partially by hybridisation. The present captive stocks of the lesser white-fronted goose are considered unsuitable for further reintroduction, or supplementation: hybridisation has involved three species, the number of hybrids is high, and all the investigated captive stocks are similarly affected. The results highlight the potential shortcomings of using captive-bred individuals in supplementation and reintroduction projects, when the captive stocks have not been pedigreed and bred according to conservation principles.

Abstract:
The south-east Caspian region of Turkmenistan is an important staging and wintering area for the globally threatened Lesser White-fronted Goose Anser erythropus. During the period 1975-2003, surveys carried out in late autumn and mid-winter recorded Lesser White-fronted Geese at a total of 14 sites. The numbers of geese fluctuated widely from a maximum of 1 850 individuals in November 1999 to none in several years. The most important sites were the Turkmenbashi, Balkan, Mihkailovskiy and Severo-Cheleken Bays in the central part of the Caspian coast of Turkmenistan, and the delta of the Atrek River in the southern part. Changes in the distribution and numbers of geese have occurred as a result of habitat degradation or alteration and other anthropogenic pressures, especially hunting. Various measures are proposed for the protection and management of the Lesser White-fronted Goose in Turkmenistan, and it is suggested that these measures could be used in the development of an international action plan for the conservation of the species in the Caspian region as a whole.
