Pandas face bamboo shortage threat
①Already threatened by a slow breeding rate and rapid habitat loss, China's endangered giant pandas now also risk losing their main food, bamboo, to climate change, claim scientists.
利与弊
A study in China's northwestern Qinling Mountains, home to around 270 pandas—about a fi
fth of the world's wild population—predicts a big bamboo decline this century as the globe warms.
"The pandas may face a shortage of food unless they can find alternative food resources; the giant panda is a picky eater."
Ninety-nine per cent of its diet ②consists of bamboo—being destroyed ③up to 38 kilograms per day. Bamboo itlf also has a slow reproductive rate, flowering only every 30 to 35 years, which means it would be slow to adapt to a change in local climate.
Bad on the data gathered for this study, rearchers predict that three bamboo species which ④make up almost the entire diet of the Qinling pandas will all but disappear in a warmer climate.
"Results suggest that almost the entire panda habitat in the region may disappear becau of climate change ⑤by the end of the 21st century," the study's authors write.
Already, deforestation is threatening the survival of about half of all bamboo species wor
ldwide.
The rearchers say bamboo distribution has historically changed ⑥in respon to changes in the climate. In the modern era, though, even if other areas were to become climatically more suited for bamboo growth, the would be ⑦far away.
The findings should be ud for planning ahead to protect areas that have a better climatic chance of providing enough food sources or begin creating natural bridges to allow pandas an escape from bamboo famine.
大熊猫面临着食物短缺的威胁
科学家们声称，由于一直以来受到低繁殖率和栖息地快速流失的威胁，中国濒临灭绝的大熊猫如今又因气候变化而陷入失去它们的主食——竹子的危险之中。
大约270只大熊猫栖息于中国西北部的秦岭山脉地区，这占世界野生大熊猫总数的五分之一。据这一地区的调查研究推测，随着全球变暖本世纪竹子的产量将平稳下滑。
“除非大熊猫能够找到另外一种食物资源来代替竹子，否则它们将很可能面临食物短缺的困境。大熊猫可是个挑剔的食客。”
大熊猫的食物中99%都是竹子，它们平均每天吃掉的竹子达到38千克。竹子本身再生率低，每单核细胞高30年至35年为一个生长周期，这也就意味着竹子适应当地气候变化的过程很慢。
根据这个调查得出的数据，调查者预测随着气候越来越暖，三种竹子将濒临灭绝。而这三种竹子正是几乎秦岭地区的大熊猫的全部食物源。
调查研究的发起者们写道：调查结果表明到饵料配方21世纪末秦岭地区基本上所有大熊猫的栖息地将很可能消失。
滥伐森林正在在并且已经威胁着世界上将近一半种类的竹子的生存。
调查者说到自古以来竹子的分布状况都随着气候的变化而波动。不过在现代，即使其他地区从气候因素上来讲更适合竹子的生长，但是这些地区与目前大熊猫保护区相隔太远，没有重合区。
这些调查结果应该用于主动保护计划中，保护那些有更好的气候条件提供充足的食物资源的地区，或者为大熊猫搭建起快速摆脱饥荒的自然通道。
