In order to study the situation of musk oxen live, researchers dressed as polar bears-musk ox-IT information

According to the daily mail newspaper reported on February 13, researchers to study whether the polar bear threatened the survival of musk ox, himself dressed up as polar bears.

Wrangel Island in the Arctic Ocean, the researchers slowly close to musk ox populations. Although in this case, the researchers may be hurt, but for the protection of musk ox, researchers cannot carry guns. And because the weather is too cold, making the pepper spray in the face of danger and cannot use. But he can jump on the ice to confound the musk ox, stop its attacks.

The researchers said, his research focuses on protecting large species that live in cold places, these species are mostly distributed in the northern Rocky Mountains, Central Asia, Asia and Alaska's Tundra all year round. Researchers said that this winter was his 11th year, he returned to the Arctic. "I want to know the temperature change for the musk ox (periods with the extinct mammoths) effects of this animal. To solve this problem, I need to determine population trends and pressures that may arise, and carefully study the animal's physiology, breeding status, predators and food sources. ”

Due to climate change habitats animals have adapted over thousands of years, ice and snow in some parts of today are rapidly dissipating, others melting at an accelerating rate. Melting sea ice makes polar bears stranded on land, and shortened the length of its hunting hunting season.

Earlier this year, NASA and the National Oceanic and Atmospheric Administration scientists issued a report according to which two independent research institutions to detect, by 2016, has its highest average global surface temperature record for three consecutive years. Warming of the polar region is the most serious, particularly in the Arctic. The most striking trend in the Arctic that we observe here is the winter temperatures rarely drop below freezing.

为了研究麝牛生存状况，研究人员扮成北极熊 - 麝牛 - IT资讯

据英国《每日邮报》2月13日报道，研究者为探究北极熊是否威胁到麝牛的生存，将自己装扮成北极熊。

在北冰洋的弗兰格尔岛,研究者慢慢接近麝牛种群。虽然这种情况下，研究人员可能会被刺伤，但出于对麝牛的保护，研究人员不能携带枪支。而由于天气太冷，制作的胡椒喷雾在遇到危险时也不能使用。但他可以在冰面上跳跃来迷惑麝牛，使其停止攻击。

研究者称，他的研究侧重于保护生活在寒冷的地方的大型物种，这些物种大多分布在落基山脉北部、中亚、亚洲和阿拉斯加的终年冻土地带。研究者表示到今年冬天，已经是他研究的第十一个年头了，他又回到了北极。“我想了解温度变化对于麝牛(与已经灭绝的猛犸象同时期)这种动物的影响。为解决这一问题,我需要判断人口增长趋势和可能出现的压力，并仔细研究这些动物的生理机能、繁殖状况,捕食者和食物来源。”

由于气候改变了动物们已经适应了数千年的栖息地,一些地方的冰雪现如今正快速消散，另外一些地方也在加速融化。不断融化的海上浮冰使得北极熊困于陆地，同时缩短了其狩猎捕食季节的长度。

今年早些时候，美国宇航局和国家海洋和大气管理局的科学家们发布了报告称根据这两家独立的研究机构探测，到2016年，已连续三年创下全球最高平均地表温度记录。变暖的情况最严重的是极地地区，尤其是在北极。我们观测到的北极地区最引人注目的变化趋势是冬天时这里的气温很少低于零度。
