Genetic Diversity of the Carrion and Jungle Crows as Evidenced by RAPD–PCR Analysis

Genetic Diversity of the Carrion and Jungle Crows as Evidenced by RAPD–PCR Analysis RAPD–PCR analysis of the genetic diversity of the carrion crow (Corvus corone) and jungle crow (C. macrorhynchos) living in the continental parts of their species ranges and on some Russian and Japanese Far Eastern islands has been performed.

In both species, the genetic polymorphism of island samples is almost two times greater than that of continental samples (62 and 31.8%, respectively, for C. corone and 81.5 and 47.2%, respectively, for C. macrorhynchos).

Abstract

RAPD–PCR analysis of the genetic diversity of the carrion crow (Corvus corone) and jungle crow (C. macrorhynchos) living in the continental parts of their species ranges and on some Russian and Japanese Far Eastern islands has been performed. Taxon-specific molecular markers have been found for each species. The genetic diversity of the carrion crow is considerably less than that of the jungle crow at the same genetic distance (P 95 = 68.2%, D N = 0.27 and P 95 = 88.4%, D N = 0.24, respectively). In both species, the genetic polymorphism of island samples is almost two times greater than that of continental samples (62 and 31.8%, respectively, for C. corone and 81.5 and 47.2%, respectively, for C. macrorhynchos). In addition, differences in genetic diversity between males and females (P 95 = 55.1 and 72.1, respectively) has been found in the carrion crow but not in the jungle crow. The gene diversity of C. macrorhynchos is greater than that of C. corone: the mean numbers of alleles per locus are 2 and 1.81, effective numbers of alleles are 1.62 and 1.43, and the mean expected heterozygosities are 0.39 and 0.30, respectively. The phenograms and phylograms significantly segregate the clusters of the carrion and jungle crows. The clustering patterns of carrion crows corresponds to the intraspecies taxonomic and geographic differentiation: subspecies C. c. corone and C. c. orientalis living in the western and eastern parts of the species range, respectively, form different subclusters. The cluster of the jungle crow does not exhibit differentiation into subspecies C. m. mandshuricus and C. m. japonensis; molecular genetic differences between them are small.
