  25日,四川卧龙国家级自然保护区管理局对外发布了首张白色大熊猫照片。

四川卧龙惊现“白色大熊猫” 专家解释说这是一种病!(双语)

  The photo, believed to be the world's first image of an albino panda, taken in the wild, and clearly shows the all-white body and paws of the panda captured by an infrared camera around 2,000 meters above sea level in the reserve.

  这张照片据信捕捉到了全球首个白色大熊猫的影像,图片清晰地显示了它的形态:毛发和爪子都呈白色。照片由保护区内海拔2000米的一台野外红外触发相机拍摄。

  albino /ælˈbiːnəʊ/:患白化病的个体

  infrared /ɪnfrə'red/:红外线

  The only part of the panda's body that is not white are its eyes, which are red, the bureau said.

  大熊猫通体白色,只有眼睛是红色的,管理局相关人员说。

  大熊猫保护和研究中心专家已确认,这只大熊猫是一例白化个体,性别还无法判定。但从体型判断,是一只亚成体或青年熊猫,年龄大概在1至2岁。

  "A panda becomes an adult at the age of 4. One year for a panda is the equivalent of about 3.5 years for a human," said an official at the center.

  “大熊猫4岁成年。熊猫寿命的1年相当于人的3.5年”,研究中心工作人员说。

  世界自然保护联盟熊类专家组成员、北京大学生命科学学院李晟研究员介绍,“白化”现象在脊椎动物中普遍存在,但比较罕见。

  It is usually caused by genetic mutations in which melanin cannot be synthesized normally, with skin and body hair expressed as white, yellowish-white or light-yellow.

  白化现象由基因突变引起,导致黑色素无法正常合成,皮肤和毛发呈白色、黄白色或浅黄色。

  单纯的“白化”突变并不会影响动物的身体结构和生理功能。

  Simple "albinism" mutations do not affect the normal body structure and physiological functions of animals, and have no significant impact on their activities and reproduction except that they are more easily spotted in the wild and their body is more sensitive to direct sunlight.

  单纯的“白化”突变并不会影响动物的身体结构和生理功能,也不会影响日常活动和繁殖,只是在环境中更容易被发现,身体对阳光比较敏感。

  Albino mutations can be inherited. Each animal has two sets of genes from its parents.

  “白化”突变基因会遗传。每个动物个体都有来自父母双方的两套基因。

  Only when the genes from both parents contain the same mutation do offspring show characteristics of albinism.

  “白化”突变基因是隐性基因,只有当来自父母双方的基因都携带 “白化” 突变,后代才会显现出白化特征。

  卧龙此次拍摄到的熊猫,表明在卧龙的大熊猫区域种群中,存在“白化”突变基因。

  The panda looks strong, and its steps are steady, a sign that the genetic mutation does not affect its daily life, Li said.

  李晟称,从照片上来看,该个体体格壮实,步态稳健,也从侧面证实了该突变可能没有影响到这只熊猫的正常生活。

  卧龙保护区工作人员说,他们将会在发现白色大熊猫的区域安装更多红外触发相机,观测大熊猫的活动。

  “If its offspring can be photographed, it will be valuable for further research .”

  “如果能拍到它的后代,对未来深入研究会很有意义。”
