Acording to <Genetic diversity of endangered brown bear (Ursus arctos) populations at the crossroads of Europe, Asia and Africa>, brown bears in Turkey, Syria, Iran and Caucasus is different from brown bears of Lebanon, so the real U. a. syriacus probable have extinct.

Acording to < Genetic diversity of endangered brown bear (Ursus arctos) populations at the crossroads of Europe, Asia and Africa>, brown bears in Turkey, Syria, Iran and Caucasus is different from brown bears of Lebanon, so the real U. a. syriacus probable have extinct. "This genetic pattern contradicts the classical taxonomy of Ursus arctos in the region, which recognizes a single subspecies (U. a. syriacus) characterized by small body size, small molars and the blondness of its coat (Kurten, 1965). However, very few of the many subspecies defined to date are monophyletic with respect to their mtDNA (Talbot & Shields, 1996; Waits et al., 1998). On the basis of mtDNA alone (which is maternally inherited), it is difficult to assess patterns of gene flow or determine whether shared states of characters reflect] common ancestry or adaptations to similar environments. In any case, occupation of the Middle East by brown bears has involved at least three of the extant clades of brown bears,gathering characteristic haplotypes in close proximity. To our knowledge, the only comparable case is that of Hokkaido brown bears, which also belong to three different clades (Matsuhashi et al., 1999), albeit closer geographically and phylogenetically than their Middle Eastern counterparts (Matsuhashi et al., 1999, 2001)."
