Population genetic analysis provides evidence for six extant subspecies of tiger: the Amur, Indochinese, Malayan, Sumatran, Bengal, and, tentatively, South China tigers. The data will lead to improved conservation strategies for these endangered animals. The cover shows an Amur tiger, one of the last 500 surviving in the Russian Far East. (See Luo, et al.)
