Scientists discover 12 new frog species in India

科学家在印度新发现12个青蛙物种

 科学家在印度新发现12个青蛙物种                              

NEW DELHI (AP) — Years of combing tropical mountain forests, shining flashlights under rocks and listening for croaks in the night have paid off for a team of Indian scientists that has discovered 12 new frog species plus three others thought to have been extinct.

新德里(美联社)—印度科学团队在热带山林进行了多年探寻,通过夜间用手电筒在岩石下照明,倾听呱呱的叫声来寻找青蛙物种,这些努力终见成效。他们发现了12个新的青蛙物种,另外还发现三种被认定已经灭绝的青蛙。

 

It's a find the team hopes will bring attention to India's amphibians and their role in gauging the health of the environment.

该科学小组希望此项发现能引起社会对印度两栖动物的重视,关注他们在测定环境健康方面的作用。

Worldwide, 32 percent of the world's known amphibian species are threatened with extinction, largely because of habitat loss or pollution, according to the group Global Wildlife Conservation.

据全球野生动物保护组织所言,全世界32﹪的已知两栖动物都面临灭绝危险,这主要是由于他们生活的栖息地缩减及环境的污染。

 

"Frogs are extremely important indicators not just of climate change, but also pollutants in the environment," said the project's lead scientist, biologist Sathyabhama Das Biju of the University of Delhi.

“青蛙在气候变迁及环境污染方面都有着极其重要的指示作用”,德里大学生物学家、项目首席科学家Sathyabhama Das Biju说道。

 

Many of the newly found frogs in India are rare and are living in just a single area, so they will need rigorous habitat protection, Biju told The Associated Press on Saturday.

在印度新发现的青蛙物种中大部分都极其罕见并且只生活在一个区域,因此这就需要我们对其栖息地进行严格的保护,比优在周六的美联社专访中说道。

 

"Unfortunately in India, conservation has basically focused on the two most charismatic animals — the elephant and the tiger. For amphibians there is little interest, little funding, and frog research is not easy."

很不幸的是,印度的保护措施主要集中在两种最备受瞩目的动物——大象和老虎身上。对于两栖动物的保护却兴趣寥寥,再加上资金短缺导致青蛙的研究困难重重。

 

Night frogs are extremely hard to find, coming out only at dark and during the monsoon season, living either in fast-flowing streams or on moist forest ground.

夜蛙往往极难发现,他们生活在水流湍急的溪流中或者潮湿的森林地带并且仅在雨季的夜间才会出来活动。

 

Biju said he and his student researchers had to sit in dark, damp forests listening for frog sounds and shining flashlights under rocks and across riverbeds. They confirmed the new species by description as well as genetics.

比优说他和他的学生研究员们只能在黑暗潮湿的森林中倾听青蛙发出的声音并且用手电筒在岩石下面搜寻。他们通过外表及遗传特征来确定这些新物种。

 

 

The 12 new species include the meowing night frog, whose croak sounds more like a cat's call, the jog night frog, unique in that both the males and females watch over the eggs, and the Wayanad night frog, which grows to about the size of a baseball or cricket ball. "It's almost like a monster in the forest floor, a huge animal for a frog, leaping from one rock to another," Biju said.

这12个新物种包括猫叫夜蛙,其叫声与猫叫类似;慢跑夜蛙,其雌雄蛙都会照看卵;还有一种瓦亚纳德夜蛙,它会长成像棒球或是板球那么大。比优说:“它就像森林地表的一只怪兽,一只巨型青蛙从一个岩石跳到另一个岩石上。

 

Three other species were rediscovered, including the Coorg night frog described 91 years ago, after scientists "had completely ignored these animals, thinking they were lost."

另外那三个重新发现的物种,包括91年前描述过的库格夜蛙,那些被科学家认为已经灭绝并完全忽视了的动物。

 

The discoveries — published in the latest issue of international taxonomy journal Zootaxa — bring the known number of frogs in India to 336. Biju estimated this was only around half of what is in the wild, and said none of India's amphibians are yet being studied for biological compounds that could be of further use in science.

该发现已经在最近的国际生物分类期刊《动物分类学》上发布,印度已知的青蛙种类就此增加到336种之多。比优估计这仅仅是野外青蛙种类的一半,他说目前对印度两栖动物的研究中没有任何关于具有科学价值的生物化合物方面的尝试。

 

"We first have to find the species, know them and protect them, so that we can study them for their clinical importance," he said.

他说:“我们首先要找到这些物种,了解他们并且保护他们,这样才能研究他们的临床价值。”

 

Biju is credited with discovering dozens of new Indian frog species during his 35-year career.

比优在35年的职业生涯中新发现了数十种印度青蛙。
