“…The extension of extreme arid areas during Pleistocene glacial periods in Africa and the Middle East was hypothesized to have promoted vicariance events and lineage divergence in several bird species adapted to arid habitats (Guillaumet et al 2008, Schweizer & Shirihai 2013, Korrida & Schweizer 2014, AlaeiKakhki et al 2016. Periods of extreme aridity might also have led to east-west vicariance across the Saharo-Sindian desert belt in larks of the genus Galerida (Guillaumet et al 2008), Houbara and Macqueen's Bustards Chlamydotis undulata/macqueenii (Korrida & Schweizer 2014), wheatears Oenanthe (Schweizer & Shirihai 2013, AlaeiKakhki et al 2016 and the House Bunting complex Emberiza striolata (Schweizer et al 2018).…”

The Dead Sea Sparrow Passer moabiticus occupies a wide and scattered range across the Near East and the Middle East, where it inhabits semi-desert habitats. Two subspecies that differ in underpart coloration are recognized. Both subspecies occur in Iran, P. m. moabiticus in western Iran and P. m. yatii in eastern Iran. Here we document the population genetics of this poorly known species using a multilocus approach. We used seven microsatellite loci and one mitochondrial locus to quantify population structure and gene flow within and between both subspecies. Our study reveals significant genetic differentiation in both nuclear and mitochondrial markers between P. m. moabiticus and P. m. yatii. Our results support the occurrence of two genetic clusters, corresponding to the two subspecies, and suggest the absence of admixed individuals, implying no recent or current gene flow between the two subspecies. Our results support a phylogeographical scenario in which the two lineages diverged from each other about 0.3-0.4 million years ago during a period of extreme aridity in two small allopatric refugia. We suggest that moabiticus and yatii may deserve species status and advocate for additional studies investigating in-depth phenotypic and behavioural variation. We stress that P. m. yatii, which possesses a small and isolated range, may deserve special conservation attention.

A plethora of studies have offered crucial insights in the phylogeographic status of Western Palearctic bird species. However, an overview integrating all this information and analyzing the combined results is still missing. In this study, we compiled all published peer-reviewed and grey literature available on the phylogeography of Western Palearctic bird species. Our literature review indicates a total number of 198 studies, with the overwhelming majority published as journal articles (n = 186). In total, these literature items offer information on 145 bird species. 85 of these species are characterized by low genetic differentiation, 46 species indicate genetic variation but no geographic structuring i.e. panmixia, while 14 species show geographically distinct lineages and haplotypes. Majority of bird species inhabiting the Western Palearctic display genetic admixture. The glaciation cycles in the past few million years were pivotal factors in shaping this situation: during warm periods many species expanded their distribution range to the north over wide areas of Eurasia; whereas, during ice ages most areas were no longer suitable and species retreated to refugia, where lineages mixed.

Implementing efforts to understand biogeographic distribution patterns and taxonomic limits within animal groups is crucial for addressing several challenges of modern zoology. Although avian phylogeography has been extensively investigated within the Western Palearctic, several families, such as shrikes, still display unresolved or neglected biogeographic patterns both between and within species, thus requiring further investigations. The Woodchat Shrike (Lanius senator) is a long-distance migratory species that exhibits three morphologically well-recognizable subspecies, whose boundaries have never been phylogenetically investigated. Here, we aimed to define the phylogeographic structure of Lanius senator throughout its breeding range and assess the genetic coherence with respect to the phenotypically described subspecies. We assembled a collection of 34 samples mainly from breeding populations of each subspecies and analysed them using four mtDNA and two nuDNA markers. We did not find clear phylogenetic structure in nuclear Ornithine Decarboxylase (ODC) and Myoglobin intron 2 (MYO), but all the four mtDNA loci (i.e., ND2, COI, cytb and CR) highlighted two main haplogroups: one including both the nominate subspecies L. s. senator and L. s. badius and a second one consisting of L. s. niloticus (the easternmost part of its range). Surprisingly, individuals phenotypically assigned to L. s. niloticus from Israel were genetically assigned to the senator/badius haplogroup. Moreover, genetic distances between haplogroups showed intermediate values between inter-intraspecies diversity usually reported for Passerines. We estimated a divergence time at ca. 890 kya (554-1.259 kya HPD). Our findings showed a mismatch in subspecies assignment using morphology and genetic information and a marked differentiation between the eastern L. s. niloticus and all other L. senator populations sampled.
