美国西海岸棱皮龟数量大幅减少-双语


Major Drop in Leatherback Sea Turtle Population off US West Coast

美国西海岸棱皮龟数量大幅减少。让北京翻译公司北京金橄榄外文翻译有限公司与您一起看看以下内容:


Scientists say there has been a major drop in the population of leatherback sea turtles off the U.S. West Coast.


科学家称,美国西海岸棱皮龟数量大幅减少。


Researchers say there was an 80 percent drop in one group of leatherbacks found off the California coast over the past 30 years.


科学家表示,过去30年间,加州海岸线上某个棱皮龟族群数量下降了80%。


One recent study found a 5.6 percent yearly decrease in the population.


最近的一项研究表明,棱皮龟族群每年数量减少5.6%。


Leatherbacks are massive sea turtles dating back to the time of the dinosaurs.


棱皮龟是大型海龟,跟恐龙同时期出现。


The animals can grow up to 1.5 meters in length and weigh as much as 680 kilograms.


棱皮龟长可达1.5米,重可达680千克。


The leatherback sea turtles found along the U.S. Pacific coast are actually born thousands of kilometers away,


美国太平洋海岸上发现的棱皮龟其实都是在千里之外的地方出生的——


on beaches in Indonesia, Papua New Guinea, Vanuatu and the Solomon Islands.


印尼、巴布亚新几内亚、瓦努阿图、所罗门群岛的海滩上。


The animals migrate 11,000 kilometers across the Pacific Ocean to feed on jellyfish in waters off the U.S. West Coast.


这些棱皮龟迁徙了1.1万千米,跨越了太平洋来到了美国的西海岸,路上的它们以水母为食。


Then, they swim back.


然后,它们会游回去。


As many as 60 percent of the leatherback turtles born in the western Pacific Ocean are believed to make the trip to California.


太平洋西海岸出声的棱皮龟中,有60%都迁徙到了加州。


Scientists are not sure why some do and others do not.


科学家不确定为什么有些棱皮龟会迁徙离开、有些则不会。


Some go farther north, to waters off Oregon or Washington state.


有些棱皮龟迁徙得更远,它们向北迁徙,来到了俄勒冈州或华盛顿州的水域。


Scott Benson is an ecologist with the U.S. National Oceanic and Atmospheric Administration's (NOAA) fisheries service in Monterey, California.


斯科特•班森是一名生态学家,任职于美国国家海洋和大气管理局(NOAA)的渔业处,在加州的蒙特利办公。


He has studied the turtles for many years and recently co-wrote a study on leatherback populations.


多年来,他一直在研究龟类,最近还与人合著了一个与棱皮龟族群有关的研究。


Benson told The Associated Press that the long trip across the Pacific demonstrates the strength of the sea turtles.


班森在接受美联社采访时表示,横跨太平洋的长途迁徙证明棱皮龟体力很强。


There are birds that go farther, but they fly.


有的鸟类的迁徙距离比棱皮龟还要长,但毕竟它们是靠飞的。


There's a whale shark that might swim a little further, but it doesn't have to come up for air, he said.


有一种鲸鲨可能游得稍微更远些,但这类鲸鲨是不需要浮上水面来呼吸空气的,他如是说道。


The leatherbacks, he noted, are actually pushing water all the way across the Pacific Ocean.


他表示,棱皮龟其实是靠推动水的方式一路横跨太平洋的。


Now, just as scientists are beginning to fully understand these unusual creatures, the turtles are quickly disappearing.


如今,就在科学家着手充分了解棱皮龟这种不同寻常的生物时,它却“人间蒸发”了一般。


Similar population decreases have also been documented at beaches where leatherbacks nest on the western Pacific.


类似的数量减少的情况在西太平洋的海滩上也有出现,那里有棱皮龟的窝。


Scientists say that if nothing changes, the leatherbacks could completely disappear from the U.S. West Coast within 30 years.


科学家表示,如果不做出任何改变的话,30年内,棱皮龟会从美国的西海岸彻底消失。


The population drops are mainly blamed on international fishing activities, the destruction of nesting grounds and climate change.


棱皮龟数量的减少主要是因为国际捕鱼活动、窝巢遭到破坏、气候变化。


The turtles were there and we finally started paying attention, said Jim Harvey,


棱皮龟的情况早就出现了,我们现在终于开始关注了,吉姆•哈维如是说道,


director of San Jose State University's Moss Landing Marine Laboratories.


他是圣何塞州立大学莫斯兰丁海洋实验室的负责人。


He was a co-writer of the new study.


他与人合著了这项新研究。


We got into looking at the story just as the story was ending, Harvey told the AP.


我们等到这个情况都快结束了的时候才开始关注,哈维在接受美联社采访时如是说道。


The study provides important information, but also shows the threats the leatherbacks face,


该研究提供了重要的信息,也表明了棱皮龟面临的威胁,


said Daniel Pauly, a fisheries professor at the University of British Columbia in Canada.


丹尼尔•保利如是说道,他是加拿大英属哥伦比亚大学的渔业教授。


Pauly, who was not involved in the study, is an international expert on the effects of fishing on ocean ecosystems.


保利没有参与这项研究,他是一名专家,研究的是渔业对海洋生态系统的影响。


The animals can be killed when they get trapped in fishing equipment.


棱皮龟被困在钓鱼用具中可能会死亡。


Scientists say the population is also harmed because a lot of turtle eggs are removed from beaches.


科学家表示,棱皮龟也因大量龟蛋被人类从海岸上挪走而受到负面影响。


Researchers say that while all the world's leatherbacks are under pressure,


科学家表示,虽然全球范围内的棱皮龟都遭受了压力,


the group that migrates for months across the Pacific faces the greatest threats.


但横跨太平洋数月迁徙而来的棱皮龟面临的威胁是最大的。


If you find the decline in one place, that might have a number of causes,


如果一个地方的棱皮龟数量减少,那有可能有多个原因,


but if you find the same estimate of decline in two places that is something much more serious, Pauly said.


但如果两个地方的数量出现大致相同的减少,情况就更为严重了,保利如是说道。


He added that the sea turtles are really in big trouble.


他补充表示,棱皮龟现在的形势真的不容乐观。


NOAA launched an aggressive plan to save leatherbacks in 2015 and is set to release a new action plan this month.


2015年,美国国家海洋和大气管理局发起了一份目标宏大的计划,旨在于本月发起一项新行动计划。


The plan is meant to persuade governments and international organizations to join efforts to save the turtles.


该计划的目的是劝说政府和国际组织加入到拯救棱皮龟的行动中。


Benson, the NOAA ecologist, said there is still time to stop the decrease, but that it will require an immediate, international effort.


美国国家海洋和大气管理局的生态学家班森表示,阻止棱皮龟数量减少的情况,现在还来得及,但需要国际各方即刻做出努力。


If nothing is done to reverse this course, this population will become extinct in the Pacific Ocean.


如果什么挽救措施都不做,那太平洋里就再也见不到棱皮龟了。
