North African hybrid sparrows (Passer domesticus, P. hispaniolensis) back from oblivion – ecological segregation and asymmetric mitochondrial introgression between parental species

Popis výsledku v původním jazyce

A stabilized hybrid form of the house sparrow (Passer domesticus) and thenSpanish sparrow (P. hispaniolensis) is known as Passer italiae from the ItaliannPeninsula and a few Mediterranean islands. The growing attention for the Italiannhybrid sparrow and increasing knowledge on its biology and genetic constitutionngreatly contrast the complete lack of knowledge of the long-knownnphenotypical hybrid sparrow populations from North Africa. Our study providesnnew data on the breeding biology and variation of mitochondrial DNA innthree Algerian populations of house sparrows, Spanish sparrows, and phenotypicalnhybrids. In two field seasons, the two species occupied different breedingnhabitats: Spanish sparrows were only found in rural areas outside the cities andnbred in open-cup nests built in large jujube bushes. In contrast, house sparrowsnbred only in the town centers and occupied nesting holes in walls of buildings.nPhenotypical hybrids were always associated with house sparrow populations.nHouse sparrows and phenotypical hybrids started breeding mid of March, andnmost pairs had three successive clutches, whereas Spanish sparrows startednbreeding almost one month later and had only two successive clutches. Mitochondrial introgression is strongly asymmetric because about 75% of the ruralnSpanish sparrow population carried house sparrow haplotypes. In contrast,npopulations of the Italian hybrid form, P. italiae, were genetically least diversenamong all study populations and showed a near-fixation of house sparrow haplotypesnthat elsewhere were extremely rare or that were even unique for the ItaliannPeninsula. Such differences between mitochondrial gene pools of Italian andnNorth African hybrid sparrow populations provide first evidence that differentndemographic histories have shaped the extant genetic diversity observed onnboth continents.
