  Study Panda’s bamboo diet appears deceptively carnivorous

  研究发现,熊猫的竹饮食似乎是食肉性的

  Despite feeding almost exclusively on bamboo, the nutrients that giant pandasconsume and absorb most closely resembles that of carnivores, a joint Chinese-Australian study revealed on Friday.

  达到周五宣布的同件中澳联合研究显示,尽管大熊猫几乎完全以竹子为用,但是大熊猫消耗和收的营养物质与食肉动物最为相似。

  The study by the University of Sydney (UoS) and Chinese Academy of Sciences (CAS) showed that 50 percent of the pandas’ energy intake comes from protein, a similar figure to wolves and feral cats.

  这项由悉尼大学和中华科学院共同进行的研究表明,熊猫摄入的能量中发生50%来蛋白质,立即同数字和狼和野猫相似。

  To achieve their findings, researchers employed an approach called nutritional geometry which considers how nutrients and dietary components mix, rather than focussing only on one nutrient in isolation.

  为证明他们的发现,研究人员使用了同种叫营养几何的方法,这种方法考虑了营养成份和饮食成分是怎样混合的,如果不是独自关注一种营养成份。

  This study demonstrates the importance of considering both foods and nutrients in understanding the evolutionary ecology of animals, exactly what nutritional geometry is designed to do, UoS’s Prof David Raubenheimer explained.

  悉尼大学的大卫·劳本海默讲课说说:“这项研究表明,在知道动物进化生态学的过程中,并且考虑食物和营养物质的重要,如果立即正是营养几何学的目的所在。”

  The findings help to show how giant pandas evolved from their carnivorous ancestors to the bamboo-munching vegans of today. It can also explain why pandas have a strange mix of herbivore and carnivore traits, Raubenheimer said.

  立即更现有助于揭示大熊猫是怎样从食肉的祖先进化到今日吃竹的纯粹素食主义者的。罗本海默商谈,立即为可以说明为什么熊猫有相同种食草动物和食肉动物的奇妙的混合特征。

  Over time giant pandas have developed a skull, jawbone and teeth, ideally adapted to chew on fibrous plant materials, as well as a "pseudo-thumb" with which to grip stems while they eat.

  乘时间的缓,熊猫已经提高出了最适合咀嚼纤维状植物材料的头骨、颌骨和牙齿,和一个“借拇指”,当它吃东西的时候可以用它来吸引植物的根。

  However, their digestive tract, digestive enzymes, and gut microbes resemble that of carnivores and not herbivores.

  但是,它的消化道、消化酶和肠道微生物与食肉动物相似,如果不食草动物。

  Based on what they eat, giant pandas absolutely belong to the herbivores, but considering the macronutrient composition of the ingested and absorbed diets, they could also belong to the carnivores, co-author Fuwen Wei from CAS said.

  中科院的合著者韦福文说道,从它吃的东西来看,熊猫绝对属于食草动物,但是考虑到摄入和收的食物中所含的大度营养成份,它为可能属于食肉动物。
