轮虫

But if that theory is correct then bdelloid rotifers, freshwater invertebrates that haven't had sex in at least 30 million years, should have been parasited into extinction long ago.

但是如果这个理论是正确的，那么蛭形轮虫，这种至少已经存活了3千万年的无性繁殖的淡水无脊椎生物，应该早就因为感染寄生虫而灭绝了。

They haven't had sex in some 30 million years, but some very small invertebrates named bdelloid rotifers should have gone extinct long ago.

蛭形轮虫这种无脊椎动物应该在很久以前就已经灭亡了，因为他们已经禁欲大约3000万年了。

The researchers, based at Cambridge University, focused on bdelloid rotifers, female microscopic organisms that live in freshwater pools.

剑桥大学的研究者们对生活在淡水池塘中的雌性微生物蛭形轮虫进行了研究。

Few creatures—even bacteria—do without sex entirely, but bdelloid rotifers are among that minority.

很少有生物是完全的无性繁殖，连细菌也不是，但蛭形轮虫却属于这个少数群体。

So while most animals are locked in evolutionary arms races with their foes, bdelloid rotifers escape them altogether simply by being carried on the wind.

所以当大多数动物都在进化的&军备竞赛&中被竞争者淘汰时，蛭形轮虫凭借风的搬运作用轻松逃离了所有进化中的竞争。

And they found that bdelloid rotifers can shake the infection by drying out, drifting away and then rehydrating once they land someplace moist but fungus-free.

他们发现蛭形轮虫通过自身脱水、飘荡到别的潮湿的但没有真菌的地方后再补水，从而摆脱感染。

And they found that bdelloid rotifers can shake the infection by drying out, drifting away and then rehydrating once they land someplace moist but fungus-free.

他们发现蛭形轮虫能够通过自身风干，然后飘走来摆脱细菌，等降落到潮湿而没有细菌的地方后，它们会再次补水。

Bdelloid rotifers, microscopic asexual freshwater invertebrates are the ultimate escape artists, able to outpace their enemies by drying up and blowing away.

蛭形轮虫，只能在显微镜下观察的无性淡水无脊椎动物是最好的&脱身专家&，它们通过&干枯&和&随风吹走&来超越竞争对手。

Bdelloid rotifers (pronounced DELL -- oyd ROWtiff-ers) are tiny, freshwater invertebrates that have long puzzled scientists because, as completely asexual animals, they should have been extinguished by parasites and pathogens long ago in evolutionary time.

蛭形轮虫这种细小的淡水无脊动物已经困扰科学家们很长时间了，因为作为一种无性生殖动物他们在进化中早就应该因为寄生虫和病原体而灭亡了。

Food compositions of M. albus were investigated in areas of three counties in Hubei province. Diets of the M. albus with body length less than 100mm change with their growth: from Rotifera and Cladocera to Oligochaeta and Chironomidae.

通过对不同产地的271尾野生黄鳝的食性的研究表明，全长小于100mm的稚鱼，其食性随着全长的生长而变化，稚鱼前期以摄食轮虫、枝角类为主，后期以水生寡毛类、摇蚊幼虫为主。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
