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。1058Please respect copyright.ＰＥＮＡＮＡRRgEbuw5na

適者生存，弱肉強食，一向被喻為大自然界的法則。1058Please respect copyright.ＰＥＮＡＮＡnycfPUB4Uk
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。1058Please respect copyright.ＰＥＮＡＮＡ9UikfFRecG

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。1058Please respect copyright.ＰＥＮＡＮＡu0D3KFUikh
1058Please respect copyright.ＰＥＮＡＮＡTmW5NL2PrV
但實情其實並非如此。1058Please respect copyright.ＰＥＮＡＮＡWgvClfZL1N

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。1058Please respect copyright.ＰＥＮＡＮＡOCsMp5HuI4

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；1058Please respect copyright.ＰＥＮＡＮＡcqDE9L0WAu
1058Please respect copyright.ＰＥＮＡＮＡfmDhMjJsoG
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。1058Please respect copyright.ＰＥＮＡＮＡZFfx2RWyO6
1058Please respect copyright.ＰＥＮＡＮＡUzD8MGzIT6
Z形態及E形態是化學用詞，用在描述化學物的形態。1058Please respect copyright.ＰＥＮＡＮＡUaZogWlTxn
1058Please respect copyright.ＰＥＮＡＮＡxaMsWx6XRr
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。1058Please respect copyright.ＰＥＮＡＮＡKfQzxMktp3
而E形態就是用樹枝當作雙耳、胡蘿蔔當作雙手的雪人。1058Please respect copyright.ＰＥＮＡＮＡbiu6lljnJB

大家所組成的元素均是一樣，但位置上卻有著不同的地方。1058Please respect copyright.ＰＥＮＡＮＡGdrF0yZHeX
1058Please respect copyright.ＰＥＮＡＮＡ1u44pOBgNT
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。1058Please respect copyright.ＰＥＮＡＮＡNE2637MrSq

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。1058Please respect copyright.ＰＥＮＡＮＡWL5npEH0WL
1058Please respect copyright.ＰＥＮＡＮＡwcGfdQFRDL
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。1058Please respect copyright.ＰＥＮＡＮＡSuoRiBvmfI
1058Please respect copyright.ＰＥＮＡＮＡ6ljdwK13UP
在這裡必須強調的是，這種關係是物種針對性的。1058Please respect copyright.ＰＥＮＡＮＡdKz2cf5B7T
1058Please respect copyright.ＰＥＮＡＮＡykey2nuH2M
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。1058Please respect copyright.ＰＥＮＡＮＡ4nELPNp3ss
1058Please respect copyright.ＰＥＮＡＮＡfXvCC4Ekle
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。1058Please respect copyright.ＰＥＮＡＮＡ2x4P1MfwfW
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。1058Please respect copyright.ＰＥＮＡＮＡbi35XVFkAn
