| genetic variation in rhipicephalus appendiculatus (acari: ixodidae) from zambia: correlating genetic and ecological variation with rhipicephalus appendiculatus from eastern and southern africa. | based on their ecology, rhipicephalus appendiculatus ticks from eastern and southern africa have been divided into three groups. we investigated how two geographic genetically differentiated stocks of r. appendiculatus from the southern and the eastern provinces of zambia, representing two ecological groups, i.e., southern african and transition groups, respectively, genetically compare to stocks from east africa (rwanda) and southern africa (zimbabwe and south africa). the its2 and two mitochon ... | 2007 | 18260504 |
