【タイトル】Machiavellian flowers: power and control in plant reproduction

【要旨】In general, plant reproduction involves interactions between participants with contrasting self-interests. Although such interactions are evident in sexual conflict, parent-offspring competition and sibling rivalry, they are most obvious for plants that rely on animals to disperse their pollen.  Pollinators typically visit flowers to obtain food and while serving their self-interest they coincidentally disperse pollen, which serves the plant's self-interest.  Although mutual benefit can result, it need not, and various characteristics of flowers act as evolutionary adaptations to manipulate pollinators and promote pollen dispersal.  Using examples drawn from my research during the past two decades I will interpret a variety of floral and inflorescence characteristics from this perspective.  These examples provide explanations for: why plants are so attractive; why they restrict pollen removal by individual pollinators; the high frequency of pollination by deceit in orchids, but not other angiosperms; and the size and structure of inflorescences, including the segregation of sex roles.


本セミナーは、GCOEアジア保全生態学コース授業科目「国際セミナーI, II」(D1,D2の必修科目)の一環として開講されます。

この科目では、一年間を通じて4回のセミナー開催を予定しています。対象となる院生の方々は、少なくとも2回は出席するようにしてください。
