MtDNA genetic diversity and structure of Eurasian Collared Dove (Streptopelia decaocto)

Abstract

The Eurasian Collared Dove (Streptopelia decaocto) is one of the most successful biological invaders among terrestrial vertebrates. However, little information is available on the genetic diversity of the species. A total of 134 Eurasian Collared Doves from Europe, Asia and the Caribbean (n = 20) were studied by sequencing a 658-bp length of mitochondrial DNA (mtDNA) cytochrome oxidase I (COI). Fifty-two different haplotypes and relatively high haplotype and nucleotide diversities (Hd±SD = 0.843±0.037 and π±SD = 0.026±0.013) were detected. Haplotype Ht1 was particularly dominant: it included 44.03% of the studied individuals, and contained sequences from 75% of the studied countries. Various analyses (FST, AMOVA, STRUCTURE) distinguished 2 groups on the genetic level, designated ‘A’ and ‘B’. Two groups were also separated in the median-joining network and the maximum likelihood tree. The results of the neutrality tests were negative (Fu FS = -25.914; Tajima D = -2.606) and significantly different from zero (P≤0.001) for group A, whereas both values for group B were positive (Fu FS = 1.811; Tajima D = 0.674) and not significant (P>0.05). Statistically significant positive autocorrelation was revealed among individuals located up to 2000 km apart (r = 0.124; P = 0.001). The present results provide the first information on the genetic diversity and structure of the Eurasian Collared Dove, and can thereby serve as a factual and comparative basis for similar studies in the future.

The Genetic Diversity and Structure of the European Turtle Dove Streptopelia turtur

“…Microsatellite markers have been used to determine the genetic diversity, gene flow, and relationships between different populations or lineages [ 11 , 13 , 29 , 30 ], while mtDNA has been applied for the analysis of genetic variability, genetic structure, and phylogeography of different Columbidae species [ 15 , 31 ]. For population genetic analysis of Columbidae species, different regions of mtDNA, the noncoding D-loop, cytb , and cytochrome oxidase I ( COI ) were used [ 7 , 15 , 17 , 30 , 31 , 32 , 33 ]. To date, there was only one study on the genetic structure of the Turtle Dove based on the results of cytb analysis, with samples analysed from 95 birds collected in eight countries of Western and Southern Europe (1–17 individuals sampled in each country) [ 7 ].…”

“…It is possible that Turtle Doves of the nominal subspecies breeding in Eastern Europe mix with S. t. arenicola on the wintering grounds [ 34 ]. Notably, two genetic groups within the mtDNA COI were also shown for the Eurasian Collared Dove Streptopelia decaocto [ 15 ]. The genetic segregation of the species can be possibly caused by the former geographic isolation of different populations [ 7 ].…”

“…Also, intraspecific genetic variation of the Feral Pigeon Columba livia , was extensively examined [ 11 , 12 , 13 , 14 ]. Meanwhile, comprehensive studies analysing genetic structure and diversity of other species of the Columbidae family are still scarce [ 15 ].…”

High Genetic Diversity among Breeding Red-Backed Shrikes Lanius collurio in the Western Palearctic

“…To illustrate this, we mention the Black Grouse (Lyrurus tetrix), which overall shows specific haplotypes for each subpopulation in the Austrian Alps [69]. Regarding the distinct haplotype clades structure of the RBS, among European bird taxa, the occurrence of a two clade structure with no geographical distinction has been previously observed in the Common Redstart (Phoenicurus phoenicurus) [70] and the Eurasian Collared Dove (Streptopelia decaocto) [71]. For the two haplotype groups characterizing the Common Redstart, Johnsen et al mention a high maximum intraspecific distance (%) i.e., 5.08 [42], whereas for the RBS the distance is 2.76.…”

Common patterns in the molecular phylogeography of western palearctic birds: a comprehensive review

“…In the dataset we compiled, several bird species show two main mtDNA haploclades. The Eurasian Collared Dove (Bagi et al 2018), Common Redstart (Hogner et al 2012) and Red-backed Shrike (Pârâu et al 2019) are characterized by two main haplotype clades, with no geographic structure. However, the Little Owl (Pellegrino et al 2014) and Great Reed Warbler (Hansson et al 2008), also with two main mtDNA groups, display Western and Eastern European specific haploclades.…”
