在我們的印象中,往往會(huì)把豬籠草與“吃小動(dòng)物”這樣恐怖的概念劃等號(hào)。其實(shí),豬籠草也可以很親切大方,與小動(dòng)物和平相處,讓我們看看這到底是怎么回事吧!
經(jīng)緯 選 陳默 譯
The pitcher plant is probably the most mysterious plant in the whole wide universe. With its unique ability to obtain food, it has inspired many people to reshape their concept on how nature works. As we might have already known, pitcher plants eat small insects. They use a sweet-smelling juice to lure an unsuspecting insect into the mouth. When the insect is unable to climb back, it can only flails[1] helplessly in the fluid until it loses energy and submits to the overpowering force of its fate. Larger pitchers could even trap small frog, snakes and birds inside. Sound scary? Pitcher plants are actually very alluring and beautiful plants. A Canadian country even makes it the official flower. Yes, it’s true! In fact, the New Foundland and Labrador province in Canada has the Purple pitcher plant as its one and only floral emblem. Meat-eating is just an everyday happening for these pretty pitcher plants. Even though they are deadly traps for mosquitoes, they can be very generous and have amazing relationships with other animals. On a report, the scientists in Brunei have finally discovered why one pitcher beauty, the Nepenthes rajah is one of the biggest in the world! Though its mouth could very well swallow a whole tree shrew[2], the researchers were confused that throughout the years of their study, they were not able to find even a single dead individual inside. Suddenly, the answer finally showed itself one day. Upon examining the inside contents of the Nepenthes rajah, they discovered a freshly delivered fecal matter[3] and soon found out that its owner is the resident tree shrew who lived nearby. Further tests have led them to conclude that indeed these little primate[4] relatives make toilet bowls out of the pitcher plant! If you think that their relationship is strange enough, hear this: it seems that the tree shrew was not the only that shares this close friendship with the pitchers! Still, on the forests of Brunei, the biologists have ascertained that bats also use the plant’s “facilities” as its rest room. And, not only that—do you know that these winged mammals can also afford to make it as its dormitory? Yes, the pitcher plant, the ever-generous landlady, has even made a girdle on its side to serve as the bat’s bed! Unlike us humans, the pitcher plants think that this is a very lucky thing! Actually, every waste matter that is excreted[5] by all animals is rich in nitrogen. And we learn in school that nitrogen is very helpful for all plants in their growth and development. Then, what could excite you more than seeing these wonderful pitchers standing in front of you? With the convenience of modern technology, we would only not see them in pictures—but you could actually bring home one if you want to! See the nature unravel its wonders within the confines of your own home. Inspire great curiosity and knowledge on children as they open their eyes to the fact that mother Earth indeed holds wonderful secrets that they have yet to unlock!

豬籠草恐怕是整個(gè)浩瀚宇宙中最神秘的植物了。它獲取食物的獨(dú)特方式激發(fā)很多人改變了自己對(duì)大自然生態(tài)機(jī)制的看法。正如我們所知的那樣,豬籠草會(huì)吃一些小昆蟲(chóng)。它們分泌出一種香甜的汁液,把毫無(wú)警惕心的昆蟲(chóng)誘騙到嘴里。當(dāng)昆蟲(chóng)無(wú)法再爬出來(lái)的時(shí)候,它只能無(wú)助地在粘液中亂動(dòng)掙扎,直到?jīng)]有力氣,最終屈從于命運(yùn)無(wú)法抗拒的安排。大的豬籠草甚至還能將小青蛙、小蛇以及小鳥(niǎo)困在里面。 聽(tīng)起來(lái)很恐怖吧?但豬籠草其實(shí)是一種很有誘惑性又漂亮的植物。加拿大某地區(qū)甚至把豬籠草視為當(dāng)?shù)氐墓俜交ǘ?。沒(méi)錯(cuò)兒,這是真的!事實(shí)上,加拿大的紐芬蘭–拉布拉多省就把紫色的豬籠草作為本省唯一的省花。 對(duì)于這些漂亮的豬籠草來(lái)說(shuō),肉是每天必不可少的一餐。盡管這對(duì)于蚊子來(lái)說(shuō)是死路一條,但同時(shí)豬籠草也可以相當(dāng)大度,與其他動(dòng)物有著驚人的微妙關(guān)系。文萊的科學(xué)家們?cè)谝环輬?bào)告中指出,他們最終發(fā)現(xiàn)為什么馬來(lái)王豬籠草(一種美麗的豬籠草)是世界上最大的豬籠草之一!雖然它的嘴大得足以吞下一整只樹(shù)鼩,但是在這么多年的研究中,研究人員卻從未在馬來(lái)王豬籠草中找到一具樹(shù)鼩尸體,這令他們十分困惑。 突然有一天,答案不言自明。經(jīng)過(guò)對(duì)馬來(lái)王豬籠草內(nèi)部物質(zhì)的檢查,他們發(fā)現(xiàn)了剛剛排泄的糞便,接著很快便查出它的主人就是住在旁邊的樹(shù)鼩。更多的測(cè)試引導(dǎo)研究人員得出了這樣一個(gè)結(jié)論:這些靈長(zhǎng)類動(dòng)物的小近親們確實(shí)把豬籠草當(dāng)作馬桶來(lái)使用了! 如果你覺(jué)得他們之間的關(guān)系太奇怪的話,那么聽(tīng)聽(tīng)這個(gè)吧:看來(lái)不僅僅是樹(shù)鼩能與豬籠草享有如此親密的友好關(guān)系!同樣,在文萊的森林中,生物學(xué)家已查明:蝙蝠也把這種植物的“衛(wèi)生設(shè)備”當(dāng)作廁所使用。不僅如此——你知不知道這些會(huì)飛的哺乳動(dòng)物還可以把它變成自己的臥室?是的,這種植物正是豬籠草,它是胸懷最寬廣的房東,甚至它的側(cè)面還有個(gè)圍擋給蝙蝠當(dāng)床用呢! 與我們?nèi)祟惒煌?,豬籠草把這當(dāng)作是一件很幸運(yùn)的事!事實(shí)上,任何動(dòng)物的排泄物都含有豐富的氮。我們?cè)趯W(xué)校也學(xué)過(guò)氮對(duì)于所有植物的生長(zhǎng)和發(fā)育都十分重要。 那么,還有什么事能比親眼看到這些神奇的豬籠草出現(xiàn)在你面前更令人激動(dòng)呢?由于現(xiàn)代科技帶來(lái)的便利,我們不僅能在照片中看到豬籠草,如果你想的話,其實(shí)也可以帶一個(gè)回家養(yǎng)!這樣在自家里便能看到大自然是如何揭開(kāi)奇跡般的神秘面紗的。當(dāng)孩子們看到地球母親確實(shí)有許多令人驚奇且尚未揭開(kāi)的謎題時(shí),這就能激發(fā)他們的好奇心并幫助他們?cè)鲩L(zhǎng)知識(shí)。 (來(lái)源:英語(yǔ)學(xué)習(xí)雜志) |
