BioNB 221: Lecture 40 Nov. 30, 2011 Lecture 40: Chemical Deception & Aggressive Mimicry Professor Robert Raguso 1. Introduction We previously discussed mimicry (and crypsis) as defensive strategies, but fraud can be used as an offensive strategy, too. The most famous examples of mimicry are stunningly visual, but other sensory modalities (smell, taste, hearing) also should be subject to signal parasitism. Is mimicry more effective when more than one sense is involved? We will use my 2004 paper (Current Opinion) on mimicry in pollination biology as a touchstone for discussion. 2. Learning Objectives - To consider ways by which mimicry and deception can be used as aggressive strategies by signal parasites. - To appreciate that plants also utilize mimicry and deceit, particularly in the context of pollination. 3. Code Breakers & Assassins Some organisms use mimicry to exploit or harm their models directly. -
