Highly specializedpollination systems, such as figs and their wasp or orchidsthat deceive bees in trying to make them mate with their floralorgans, are intuitively appealing to most people and have, therefore,gained far more attention both in popular and scientific literaturethan the more generalized pollination systems. For a long timethe dominant view was that many, or perhaps even most, plantpollinatorinteractions were specialized. In 1996 Waser and his colleaguestried to stir things up by writing an article in which theyargued that, in contrast to common belief, generalization waswidespread in plantpollinator systems. Ten 相似文献
