| In view of the dramatic climatic and vegetation changes during Quaternary, and later man-induced changes, three hypotheses may be proposed to explain the timing of the population expansion of the grey partridge (Perdix perdix) in Western Europe: A) Northwards expansion started shortly after onset of late Quaternary warming (temperate climate zone bird); B) Expansion depended on initial clearing for cultivation and by animal husbandry (non-forest landscape bird); C) Expansion started when cultivated fields and pastures became dominant landscape features after ca. 700 BP. These hypotheses were tested analysing population structure, isolation by distance and timing of demographic and spatial population expansions reflected by mtDNA control region. Timing of... |

| Non-local population stocking can have adverse genetic effects through loss of genetic diversity and introgressive hybridisation in wild populations exploited by man. The grey partridge (Perdix perdix) has been an important European game species for centuries, widely subject to translocation and stocking. After ca 80 years releasing reared grey partridges into Danish wild partridge areas, this study investigated whether an indigenous Danish grey partridge still existed. We predicted that (i) an indigenous Danish partridge would belong to the western European clade (W1) and (ii) would be more closely related to the historical, indigenous grey partridges than to farm bred partridges. These predictions were tested analysing the variation in the mitochondrial... |

| The analysis of the haplotype diversity represented by the sequences of the control region in the mitochondria in Danish partridges identified signals of population expansion as was the case in other European grey partridges. Based on this genetic analysis of the Danish recent and historical grey partridges together with previously analysed grey partridges from Germany, Poland, Hungary, France and Italy, it is hypothesized that the timing of the Grey partridge population expansions up through western Europe and the following dispersal of the grey partridge from the last LGM refugium in the French Pyrenees might be explained by the origin and spread of agriculture through Europe i.e. “following the plough”. |
