Phylogeography of the rock partridge (Alectoris graeca).

摘要: We used mitochondrial DNA control-region and microsatellite data to infer the evolutionary history past demographic changes in 332 rock partridges (Alectoris graeca) sampled from throughout species' distribution range, with exception of central Balkans region. Maternal biparental markers indicated concordantly that partridge populations are structured geographically (mtDNA phiST = 0.86, FST 0.35; RST 0.31; P < 0.001). Phylogenetic analyses 22 mtDNA haplotypes identified two major phylogroups (supported by bootstrap values 93%), splitting Sicily vs. all other at an average Tamura-Nei genetic distance 0.035, which corresponds 65% between closely related species Alectoris. Coalescent estimates divergence times suggested were isolated for more than 200000 years. This deep subdivision was confirmed multivariate, Bayesian clustering population assignment genotypes, supported also a Alps Apennines, Albania Greece. Partridges Apennines Albania-Greece probably connected gene flow since recently through late Pleistocene Adriatic landbridge. Deglaciated colonized distinct and, perhaps, not yet source populations. Bottleneck mismatch indicate have lost variability declines, did expand recently. areas could been recolonized without any strong expansion. Genetic partially subspecies subdivisions, allowed delimiting conservation units. Rock Sicily, formally recognized as A. g. whitakeri, met criteria significant unit.
