The lesser white-fronted goose is a sub-Arctic species with a currently fragmented breeding range,which
extends from Fennoscandia to easternmost Siberia.The population started to decline at the beginning of
the last century and,with a current world population estimate of 25,000 individuals,it is the most threa-
tened of the Palearctic goose species.Of these,only 30 –50 pairs breed in Fennoscandia.A fragment of the
control region of mtDNA was sequenced from 110 individuals from four breeding,one staging and two
wintering areas to study geographic subdivisions and gene flow.Sequences de fined 15 mtDNA haplotypes
that were assigned to two mtDNA lineages.Both the mtDNA lineages were found from all sampled
localities indicating a common ancestry and/or some level of gene flow.Analyses of molecular variance
showed signi ficant structuring among populations (/ 0.220,P <0.001).The results presented here to-
gether with ecological data indicate that the lesser white-fronted goose is fragmented into three distinctive
subpopulations,and thus,the conservation status of the species should be reconsidered.
