Non-local population stocking can have adverse genetic effects on wild populations through loss of genetic diversity and introgressive hybridization. The grey partridge (Perdix perdix) has been an important European game species for centuries, widely subject to translocation and stocking. After c. 80 years of releasing reared grey partridges in Denmark, this study investigated whether an indigenous Danish grey partridge still existed. If so, they would (1) belong to the western European clade (W1) and (2) be more closely related to the historical, indigenous grey partridges than to farm-bred partridges. These predictions were tested by analysing the variation in both the mitochondrial control region (CR1) and microsatellite markers in museum samples representing the ancestral indigenous Danish grey partridge, contemporary wild grey partridges and farmed grey partridges from the five largest farms in Denmark. Phylogeography and population structure analyses showed traces of the indigenous Danish grey partridges amongst recent wild partridges in certain areas and significant genetic differences between farmed partridges and historical and recent partridges. The results also showed that the indigenous Danish grey partridges belonged to the western European clade (W1 haplotype). A foreign stocking effect was detected on the remote island of Bornholm, where the current population originated from introduced Danish and Bohemian grey partridges. The loss of haplotype diversity over time in certain geographical areas probably results from serious declines in wild Danish grey partridge numbers in recent decades. This, combined with the observation that hybridization between released stocked and wild partridges can occur, may complicate recovery of partridge populations. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, 105, 694–710.

    • "It has been intensively bred and re-introduced by both hunters and conservationists in many European countries (Vidus-Rosin et al. 2010; Buner et al. 2011). Most studies on this species have concentrated on population genetics (Andersen and Kahlert 2012) and behaviour (Beani and Dessifulgheri 1995; Svobodova et al. 2013), with relatively few immunological studies undertaken (but see Cucco et al. 2006, 2007; Vinkler et al. 2014a, b). Knowledge of the grey partridge immune system is, therefore, highly fragmentary; despite the fact that the grey partridge is susceptible to some human (e.g. "

    ABSTRACT: Toll-like receptors (TLRs) are a cornerstone of vertebrate innate immunity. In this study, we identified orthologues of TLR4, TLR5 and TLR7 (representing both bacterial- and viral-sensing TLRs) in the grey partridge (Perdix perdix), a European Galliform game bird species. The phylogeny of all three TLR genes follows the known phylogeny of Galloanserae birds, placing grey partridge TLRs (PePeTLRs) in close proximity to their turkey and pheasant orthologues. The predicted proteins encoded by the PePeTLR genes were 843, 862-863 and 1,047 amino acids long, respectively, and clearly showed all TLR structural features. To verify functionality in these genes we mapped their tissue-expression profiles, revealing generally high PePeTLR4 and PePeTLR5 expression in the thymus and absence of PePeTLR4 and PePeTLR7 expression in the brain. Using 454 next-generation sequencing, we then assessed genetic variation within these genes for a wild grey partridge population in the Czech Republic, EU. We identified 11 nucleotide substitutions in PePeTLR4, eight in PePeTLR5 and six in PePeTLR7, resulting in four, four and three amino acid replacements, respectively. Given their locations and chemical features, most of these non-synonymous substitutions probably have a minor functional impact. As the intraspecific genetic variation of the three TLR genes was low, we assume that either negative selection or a bottleneck may have reduced TLR population variability in this species.

    • "The Grey Partridge is a common bird of the Eurasian agricultural landscape, but is presently disappearing in many regions (Kuijper et al. 2009). Therefore, in many European countries, Grey Partridges are artificially bred and released to reinforce the local populations (Andersen and Kahlert 2012; Buner et al. 2011; Liukkonen 2006; Vidus-Rosin et al. 2010). However, currently, the survival rate of the released birds is usually low because of predation (Sokos et al. 2008). "

    ABSTRACT: Birds express various secondary ornaments that can indicate individual condition and health. Amongst these, red-coloured carotenoid-based ornaments are supposed to be particularly valuable predictors of individual quality, due to their sensitivity to oxidative stress. Nevertheless, melanin-pigmented traits might also signal health and immune functions. Both types of ornaments may be either skin-based or feather-based, each differing in their dynamics. In the present study, we compared the health- and stress-indicating capacity of melanin-based feather ornamentation and putatively carotenoid-based skin ornamentation in a single species—the Grey Partridge (Perdix perdix), a vulnerable avian species of the European agricultural landscape. In captive males, we firstly verified the carotenoid content of the red-coloured skin tissue behind the eye by chromatography (HPLC). Secondly, we assessed the individual health status of all males by examining differential leukocyte count, the frequency of immature erythrocytes, malaria prevalence and proinflammatory immune responsiveness to phytohaemagglutinin (PHA). Both the size of the melanin-based ornament and red chroma of the carotenoid-based ornament were related to the heterophil:lymphocyte (H/L) ratio. Hence, in the Grey Partridge, both redness of the skin ornament and area of the feather ornament may serve as honest indicators of individual health and long-term stress. However, the two ornamental components were unrelated to each other, and the directions of their association to the H/L ratio were opposite. We therefore propose that, in this species, larger melanin-based feather ornamentation size is linked to higher levels of stress (possibly caused by more intensive social interactions with other males), while the level of expression of the carotenoid-based skin ornamentation more reliably signals actual individual health status. Our results are potentially valuable from the perspective of Grey Partridge conservation efforts, as they indicate a simple method for assessing individual quality in this species.
