Meet the (Newest Known) Beetles! 【科学60秒】 新发现的甲壳虫引发的思考 “The Creator would appear…endowed with a passion for stars, on the one hand, and for beetles on the other.” That quip from biologist and atheist J.B.S. Haldane in 1949 is really about the extraordinary number of beetles researchers had characterized, some 300,000 at that time. 上帝会出现…一方面赋予星球热情,同时也赋予甲壳虫热情。这句话正来自于生物学家以及无神论者 J.B.S. Haldane,他1949当时在感叹甲壳虫的数量,那时研究人员们已经确认大约300000种。 Now we know of about 400,000 beetles. And scientists have just added 98 previously unlisted beetle species to that tally, as well as one rediscovered species thought to be extinct. 现在我们大概知道有400,000种了。科学家们只在 甲壳虫种类标签中增加了之前没有列出来的98种,还重新发现了之前被认为已经灭绝了的一种。 The beetles hail from Bali, Java and Lombok in Indonesia, showing once again that islands can be major cradles of biodiversity. The 99 species can be found in the open access journal ZooKeys, and in the leaf litter of Indonesian forests. [Alexander Reidel et al, Ninety-eight new species of Trigonopterus weevils from Sundaland and the Lesser Sunda Islands] 从Bali,Java到印尼的Lombok的甲壳虫风暴再次显示,岛屿能够成为生物多样新的主要发源地。这上述增加的99种已经可以在Zookeys动物志杂志上查到,同时你也能在印尼森林中的散落的树叶上发现它们。 But those forests are falling, to make room for people and palm oil plantations. With the forests go the forest creatures, including unique fauna like these newly discovered beetles. And there no doubt exist many, many more unknown species, as the tropical forests of Indonesia remain largely unexplored—despite expeditions since at least the time of naturalist Alfred Russel Wallace, co-discoverer with Darwin of evolution via natural selection. 但是这些森林面积正在减少,还不是为了要给人类增加居住面积和棕榈树种植园。随着森林面积的减少,一些森林中产生出的物种包括一些独有的动物种类就像是那些刚刚被发现的甲壳虫们也随之减少。我们相信那里还有许许多多未知的物种,因为印尼的热带雨林还保持着大量原始的为开发的地带——尽管人类的探索至少从自然博物学家Alfred Russel Wallace那个时代就开始进行了,他和达尔文当时可是一起通过自然选择提出进化论的哦。 The question is, will deforestation wipe away the other unknown insects—and nematodes, microbes and other uncharismatic microfauna—before we had a chance to know them? 问题就是,是否森林开发会彻底摧毁其它还被我们知道的昆虫——以及线虫阿,微生物阿以及其它未被神明感召 出现的显微原生动物群——当然是在我们还有机会发现了解它们之前?
