Africa's Baobab Trees Are Dying
非洲猴面包树正在经历神秘死亡
Baobab trees are not only iconic images of dry, hot areas of Africa. Baobabs are important because they supply water and food for people and animals. They are sometimes called "the tree of life."
猴面包树不仅是非洲干燥、炎热地区的标志性景象。猴面包树还十分重要,因为它为人类和动物们提供水和食物。猴面包树有时被称为“生命之树”。
Yet, say researchers, some baobabs are mysteriously dying.
然而,研究人员说一些猴面包树正在神秘地死去。
Nine of the 13 oldest trees, aged between 1,000 and 2,500 years, have died in the early part of this century. Researchers reported the finding in the scientific journal Nature Plants.
13棵1000岁到2500岁最古老的猴面包树中有9棵在本世纪初已经死亡。研究人员在科学杂志《自然—植物》中报道了这一发现。
The sudden collapse is "an event of unprecedented magnitude," the researchers wrote. They believe that never before have so many old trees died in such a short period. These baobabs were found in the southern African countries of Botswana, Namibia, South Africa, Zambia and Zimbabwe.
研究人员写道,猴面包树突如其来的死亡是“史无前例的大事件”。他们认为在这么短的时间内从未有过如此多古老的猴面包树死亡。这些猴面包树在非洲南部国家博茨瓦纳、纳米比亚、南非、赞比亚和津巴布韦所发现。
Researchers do not know for sure why the trees died. But they note that temperatures have risen and rainfall decreased in recent years.
研究人员不确定猴面包树为什么会死亡。但他们指出近年来气温上升,降雨量减少。
Stephan Woodborne helped to prepare a report on the study. Woodborne is with South Africa's National Research Foundation. He says the researchers do not think that baobabs across the continent are dying out. Instead, they believe the climate of southern Africa is changing.
斯蒂芬·伍德伯恩(Stephan Woodborne)帮助准备了一份关于该研究的报告。伍德伯恩在与南非国家研究基金会合作。他说,研究人员不认为整个非洲大陆的猴面包树会灭绝。相反,他们认为非洲南部的气候正在改变。
Researchers have observed few young trees in the places where the old trees are dying. As a result, Woodborne says, baobab trees will probably stop growing in some places, and may start growing in others. He calls the move a reaction to "climate forcing."
研究人员在猴面包树死去的地方观察到几乎没有幼树生长。因此,伍德伯恩说,猴面包树在一些地方可能停止了生长,可能会在其他地方开始生长。他对此称作是对“气候强迫性”的应对。
Historically, baobabs are often found in areas where elephants, rhinoceros and other wildlife live.Elephants help the trees spread when they eat baobab fruit. The seeds often grow in the nutritious elephant dung.
历史上,猴面包树通常生长在大象、犀牛和其他野生动物居住的地区。在大象吃猴面包果时,它们帮助猴面包树生长。猴面包树的种子经常在大象营养的粪便中生长。
Baobabs take in large amounts of water during the rainy season and store it in their trunks and tree branches. The water gives the trees their wide shape. Large trees can store as much as 140,000 liters.Thirsty elephants tear off the trees' bark and wood to get to the water inside.
猴面包树在雨季吸收大量雨水,并将其储存在树干和树枝中。水使猴面包树生长的更加粗壮。大的猴面包树可以存储多达140,000公升的水。口渴的大象撕掉猴面包树的树皮和树干以吸取其中的水。
Baobabs are also important to people. Researcher Stephan Woodborne notes that communities have been using the trees for a long time. His group has found many archaeological remains underneath ancient trees from societies that lived hundreds of years ago.
猴面包树对人们也十分重要。研究员斯蒂芬·伍德伯恩指出,社区也长期使用猴面包树。他的团队在几百年前社会中古老的猴面包树下发现了许多考古遗迹。
Even today, people gather around the trees for religious events and to communicate with family and friends who have died. People also use the baobab fruit to make drinks and mix with milk to create a kind of yogurt. In addition, the trees offer protection from the sun on hot summer days.
时至今日,人们仍然聚集在猴面包树的周围进行宗教活动,并向死去的家人和朋友倾诉。人们还使用猴面包果制作饮料,并将它与牛奶混合制作酸奶。此外,猴面包树在炎热的夏天可以提供防晒保护。
Anna Munzhelele lives near the Limpopo River in South Africa. She said eating baobab fruit makes people strong. "It's like a type of medicine, we get energy from it," she said.
安娜(Anna Munzhelele)住在南非的林波波河附近。她说吃猴面包果会使人变得强壮。她说,“它就像是一种药,我们从中获取能量,”。
