上一篇的深入淺出講述了人體的體味，緊接以來的這一篇將會講述一下大自然界的「體味」互動。1347Please respect copyright.ＰＥＮＡＮＡS0Qpg7c3ls

適者生存，弱肉強食，一向被喻為大自然界的法則。1347Please respect copyright.ＰＥＮＡＮＡowxUFmSRfb
植物作為食物鏈的最底層，大多時候也逃不過被食物鏈上層生物侵食的局面。1347Please respect copyright.ＰＥＮＡＮＡ8WuajXUcRq

圖1為毛蟲獵食樹葉的畫面，這棵植物並不是捕蠅草系列，看起上來的確沒有任何反擊或防禦的手段，任人魚肉。1347Please respect copyright.ＰＥＮＡＮＡvKZS1jsKUs
1347Please respect copyright.ＰＥＮＡＮＡLS8Nd74FY5
但實情其實並非如此。1347Please respect copyright.ＰＥＮＡＮＡior9vliG1k

圖2為椿象從後出現，反過來獵食毛蟲的畫面。然而，椿象的出現並不是偶然，而是植物暗中「召喚」而來的。1347Please respect copyright.ＰＥＮＡＮＡj1PrzdX75o

圖3，當樹葉收到傷害的時候，它們會即時釋放出一堆統稱為 Green Leave Volatiles(GLV)的化合物（Ref1)，這個情況下，毛蟲的口水包含著一些物質，會將這些GLV化合物由Z形態轉化成為E形態；1347Please respect copyright.ＰＥＮＡＮＡcH3SmPxs7q
1347Please respect copyright.ＰＥＮＡＮＡlBZV6Verhk
這物質究竟是甚麼，科學家暫時還沒清楚，只是知道該物質在高溫下便會失效。1347Please respect copyright.ＰＥＮＡＮＡubxNn8NpYj
1347Please respect copyright.ＰＥＮＡＮＡfaVd3hfTXZ
Z形態及E形態是化學用詞，用在描述化學物的形態。1347Please respect copyright.ＰＥＮＡＮＡg8MtFYFpkT
1347Please respect copyright.ＰＥＮＡＮＡ0UZqC8gETQ
強硬來說的話，Z形態就是用胡蘿蔔當作雙耳、樹枝當作雙手的雪人。1347Please respect copyright.ＰＥＮＡＮＡEyGFDrl9l3
而E形態就是用樹枝當作雙耳、胡蘿蔔當作雙手的雪人。1347Please respect copyright.ＰＥＮＡＮＡhnUcMSN7Oc

大家所組成的元素均是一樣，但位置上卻有著不同的地方。1347Please respect copyright.ＰＥＮＡＮＡbzNiN2foAT

我並沒有能力再以更深入淺出的方式解釋，有興趣的話可以自行Google。1347Please respect copyright.ＰＥＮＡＮＡUolXYUKUp4

圖4）對於椿象來說， E形態的GLV是一種非常強大的吸引劑，亦因而被吸引前來，反咬毛蟲。1347Please respect copyright.ＰＥＮＡＮＡ615Uz7JZPp
1347Please respect copyright.ＰＥＮＡＮＡ4rCBLDQU0f
所以整件事情的來龍去脈，就是毛蟲傷害樹葉的時候，其口水觸化樹葉裡頭的摔發性化學物轉變，其轉變的化合物吸引捕食毛蟲的獵人前來，因而「間接」地救了樹葉一命。1347Please respect copyright.ＰＥＮＡＮＡu5bZF8r8r4
1347Please respect copyright.ＰＥＮＡＮＡSHbw1fzVgx
在這裡必須強調的是，這種關係是物種針對性的。1347Please respect copyright.ＰＥＮＡＮＡOeMszX8Im4
1347Please respect copyright.ＰＥＮＡＮＡmV3sRTpgFF
科學家在一篇學術文章（Ref1)證實，若果毛蟲品種並不是圖1列明的那一個品種，其口水是不會觸發樹葉化合物Z到E的轉變。1347Please respect copyright.ＰＥＮＡＮＡdHmnsHiO4o
1347Please respect copyright.ＰＥＮＡＮＡ4I8gfjCFic
植物是否會用不同的方式應付不同品種的入侵者，這暫時還是未知之數。1347Please respect copyright.ＰＥＮＡＮＡdT8Ma7f6QZ
但至少圖1-4的物種互動已有科學證據支持，由此已經可以看得出大自然物種之間的互動是絕非簡單的。1347Please respect copyright.ＰＥＮＡＮＡgndA7RoP8o
