1 Betr.: Genetics of the Fennoscandian subpopulation of the Lesser White- fronted Goose.
The Lesser White-fronted Goose is a monotypic species and formerly had a continuous distribution in the southern tundra between Lapland and Chukotka (ALPHÉRAKI 1904, DEMENTIEV & GLADKOV 1952). Since the first population estimates of the 1950’s, a drastic decrease in numbers was recorded from mor...

| Summary: | The Lesser White-fronted Goose is a monotypic species and formerly had a continuous distribution in the southern tundra between Lapland and Chukotka (ALPHÉRAKI 1904, DEMENTIEV & GLADKOV 1952). Since the first population estimates of the 1950’s, a drastic decrease in numbers was recorded from more than 100,000 individuals in the 1950’s (USPENSKI 1965) to less than 27,000 birds in the 1990’s (DELANY & SCOTT 2002). During the 1930’s regularly flocks of c. 50,000 Lesser Whitefronts were recorded in the Western Palearctic (RINGLEBEN 1957) and during the 1950’s the Western Palearctic population was still estimated at more than 50.000 birds (USPENSKI 1965), but in the 1990’s numbers recorded in this region during midwinter counts never exceeded 10.000- 13,000 (DELANY & SCOTT 2002, LORENTZEN et al. 1999) Since the 1980’s on most regularly monitored sites the population numbers decreased with |
