“…In line with previous results, we also found discordance between mitochondrial markers of the same individuals: mitochondrial DNA heteroplasmy is a known phenomenon in both plants and animals [65], and it was also already described in both the Grey and Rock Partridges [21,40].…”

“…The spread of allochthonous genotypes from artificially translocated or farm-reared partridges into conspecifics or congeneric wild populations is a known pattern already found in several previous analyses [15,16,18,40,41,44,[58][59][60]. Consistent with these results, we found haplotypes of the allochthonous A. chukar in Italian A. graeca (Table S1).…”

“…Furthermore, given the highlighted possible inconsistence between different markers, in selecting individuals for restocking or reintroduction interventions, it should be appropriate to test more than one marker. This should be encouraged especially in the case of Grey Partridge conservation programs for which the genetics is still based on mtDNA [ 18 , 39 , 40 ].…”

“…Diversification in this genus is considered related to the Tibetan Plateau uplift combined with Pleistocene glaciations [ 38 , 39 ]. Among these species, only the Grey Partridge is naturally present in Italy and hybridization problems were previously investigated principally between conspecifics farm-reared and wild individuals [ 18 , 40 ].…”

Translocations and releases of farm-reared birds are considered among the major drivers of genetic pollution with consequent loss of genetic diversity in wild populations. In this study, we aimed to assess the extent of hybridization and introgression in the Italian partridges as a consequence of translocation. We surveyed two mitochondrial markers and one nuclear marker of Alectoris and Perdix from collections (museums and private collections), extant wild populations and farms. Consistent with previous studies, we found haplotypes of allochthonous species within the same genus, likely due to introductions for hunting activities. In addition, we found hybrids between Perdix and Alectoris species with genetic markers from both genera in single individuals. Such introgression was bidirectional and in both mitochondrial and nuclear markers. Counterintuitively, most of the hybrid samples came from collections before the 1950s, when large-scale translocations started, from wild populations where Grey Partridge (Perdix perdix) and Rock Partridge (Alectoris graeca) overlap in their distribution, whereas only one hybrid occurred among the farmed birds. Our results suggest that Perdix and Alectoris species can hybridize in nature and that artificial translocations and releases of farm-reared birds for restocking or reintroduction purposes may be only partially responsible for the genomic mismatches of Italian partridges.

“…1). As mentioned in previous similar studies (Wernick et al, 2016;Williams et al, 2019;Pizzirani et al, 2020;Ricardo et al, 2020;Tikochinski et al, 2020) double peaks on sequence traces with both alleles from one individual were identified as mitochondrial heteroplasmy and a single individual with two haplotypes. At least one heteroplasmy was detected in 93 of 157 individuals for COI and at least 105 of 170 individuals for CytB in the current study.…”

Bombus terrestris dalmatinus is naturally common in many countries, including Turkey, and is also used commercially for the pollination of greenhouse plants. Intensive commercial production and international trade in many countries are considered as reasons for the disappearance of some natural populations. Hybridization of native bumble bees with those produced commercially, but having escaped from greenhouses and colonization of these commercial bees in natural habitats are cause for concern. In order to assess this concern, B. t. dalmatinus workers were collected from twelve different populations: five commercial producers, three surrounding greenhouse centers, three natural areas at least 30 km away from greenhouses, and one more recent greenhouse zone in Antalya, Turkey. The genetic variations and relationships among the twelve populations were estimated using SNP haplotypes determined in mitochondrial COI and CytB. Twenty and sixteen haplotypes were obtained for COI and CytB, respectively. A single haplotype, H1, was widespread with a high frequency in all individuals for both genes. Individuals collected from around greenhouse centers and commercial companies had more common haplotypes. The genetic variations of intra-populations were higher than the interpopulations in both COI (65.41%>34.59%) and CytB (72.47%>27.53%). The natural and commercial populations were genetically more distant from each other considering Fst values. However, samples from near the greenhouses had a higher similarity with the commercially produced samples, while the natural populations far away from greenhouses still retained their genetic distinctiveness.

First evidence of heteroplasmy in Grey Partridge (Perdix perdix)

Abstract: We report for the first time the occurrence of heteroplasmy in Grey Partridge (Perdix perdix) revealed by means of two mitochondrial fragments. The possible serious biological and management implications of this exception to unilateral inheritance of mtDNA were underlined.
