Study Panda’s bamboo diet appears deceptively carnivorous

研究发现,熊猫的竹子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.

上周五公布的一项中澳联合研究显示,尽管大熊猫几乎完全以竹子为食,但大熊猫消耗和吸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国科学院共同进行的研究表明,熊猫摄入的能量中有50%来自蛋白质,这一数字与狼和野猫相似。

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.

为了证明他们的发现,研究人员采用了一种叫做营养几何的方法,这种方法考虑了营养成分和饮食成分是如何混合的,而不是单独关注一种营养成分。

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·劳本海默教授解释说:“这项研究表明,在理解动物进化生态学的过程中,同时考虑食物和营养物质的重要性,而这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.

这一发现有助于揭示大熊猫是如何从食肉的祖先进化到今天吃竹子的纯素食主义者的。罗本海默说道,这也可以解释为什么熊猫有一种食草动物和食肉动物的奇特的混合特征。

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.

随着时间的推移,大熊猫已经进化出了最适合咀嚼纤维状植物材料的头骨、颌骨和牙齿,以及一个“假拇指”,当它们吃东西的时候可以用它来抓住植物的茎。

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

然而,它们的消化道、消化酶和肠道微生物与食肉动物相似,而非食草动物。

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,从它们吃的东西来看,大熊猫绝对属于食草动物,但考虑到摄入和吸收的食物中所含的大量营养成分,它们也可能属于食肉动物。
