How do the mysterious snow leopards survive in the cold mountains? It turns out that every physical feature of the “King of the Snowy Mountains” helps them with the cold.
神秘的雪豹如何在寒冷的高山上生存?原来“雪山之王”的每个身体特征都成为它们的“护身符”。
Listed as a vulnerable species, there are at least 4,500 snow leopards in China, making up more than half the species’ global population.
作为“易危”物种,雪豹在中国的数量至少有4500只,约占全球总数的一半以上。
Their short ears reduce heat loss. A shallow nasal cavity warms the air before it reaches the cat’s lungs. Their jaws can open wider than 70 degrees, making it easier for them to eat larger prey, including bharal, ibex and white-lipped deer. Their long, thick tail is roughly the same length as its body. The tail can also act as a blanket or scarf, covering the animal’s mouth and nose when it lies down. Snow leopard fur is 20 times denser than human hair.
它们短小的耳朵能减少热量的散失。较浅的鼻腔空间,可在空气到达肺部前将其加热。而它们能够张开超过70度的颌骨,使它们可以轻松吃下岩羊、北山羊和白唇鹿等较大猎物。它们长而浓密的尾巴,长度和身体相当。尾巴还可以充当毯子或围巾,在雪豹躺下时覆盖住口鼻。雪豹皮毛比人类毛发密集20倍。
China is home to the animal’s key habitat, which comprises about 1.1 million square kilometers. The snow leopard’s natural habitat is in the mountains, at altitudes between 2,000 meters and 5,000 meters. Snow leopards are regarded as barometers of high mountain ecosystems. When the population declines, it likely indicates that the local ecosystem is under pressure or being damaged.
中国是雪豹的主要栖息地,它们生活的地区占地约110万平方公里。雪豹分布的自然栖息地为海拔2000至5000米的山区。雪豹被视为高山生态系统的晴雨表。当它们的种群数量下降时,意味着当地生态系统可能正面临压力或遭受破坏。
The snow leopard’s core distribution areas still retain their natural state to a high degree, thanks to shelter provided by national parks and nature reserves, according to the National Forestry and Grassland Administration.
据国家林业和草原局表示,得益于国家公园和自然保护区等保护地的庇护作用,雪豹的核心分布区仍保持着较高程度的自然状态。
Meanwhile, snow leopards continue to face threats to their survival because of problems resulting from human activities persisting on the edges of their distribution areas, leading to declines in prey po
