Phylogenetic Relationships of Monal Pheasants Lophophorus Inferred from Sequences of Mitochondrial Cytochrome b Gene

The phylogeny of the monal pheasants (Lophophorus) and their relationships to some species of the genera Tragopan,Pucrasia and Ithaginis were studied by comparing mitochondrial cytochrome b (cyt b) nucleotide sequences.The molecular phylogenetic trees show that:①the genus Tragopan and the genus Pucrasia share a common ancestor which is the sister taxon of the ancestor of the genus Lophophorus;②the genus Lophophorus had evolved into two branches:One was the Sclaters Monal;the other included the Chinese Monal and the Himalayan Monal.Considering its molecular phylogeny,distribution patterns and morphological evidences,the genus Lophophorus might originate in the Hengduan mountains region of southwestern China.

白尾梢虹雉(Lophophorus sclateri)隶属于鸡形目(Galliformes)雉科(Phasianidae)虹雉属(Lophophorus)鸟类[1],中国分布于西藏和云南,见于西藏东南部的米林、易贡藏布下游地区、丹巴曲上游山脉和伯舒拉岭等地,在云南沿怒江两岸的高黎贡山和怒山山脉分布。

色彩绚丽的尼泊尔国鸟——棕尾虹雉

大家好,我叫棕尾虹雉,是鸟纲、鸡形目、雉科、虹雉属下的一种珍稀动物,主要分布在中国西藏南部、尼泊尔以及喜马拉雅山脉地区。我是一只雄鸟,头顶上长有蓝绿色的羽冠,身上长有如彩虹般绚丽的羽毛,红棕色的尾巴则像一把漂亮的羽扇,因此人们也叫我“九色鸟”。更让我引以为傲的是尼泊尔将我视为吉祥、美好的象征,把我奉为国鸟。

高黎贡山观“雪鹅”

在云南的极西部,有一条巍峨陡峭的狭长山脉,由北向南亘延数百千米。她就是美丽而神奇的高黎贡山。高黎贡山地势险峻,海拔变化剧烈,大部分山体20千米水平面的垂直高差在2500米以上。
