吸引朋友的视觉信号也可能吸引敌人。人们普遍认为花药和花粉的鲜艳颜色可以吸引传粉媒介。在这里，我们假设花药的视觉隐匿，特别是花粉，在开花植物中应该受到青睐，因为对花粉收集者的保护减少了雄配子的损失。为了了解与花粉颜色相关的适应性策略，我们使用光谱仪测量了来自中国西南部横断山脉自然群落的 104 个昆虫授粉开花物种的花粉、未裂开的花药囊及其背景花冠的颜色。这些物种的花药、花粉和花冠的颜色各不相同。暴露花粉的颜色多样性显着高于隐藏花粉，其中花药被花冠包围或遮挡。花粉暴露的物种中花粉和花冠之间的颜色对比度明显小于花粉隐藏的物种。与花药颜色不同，暴露的花粉颜色往往与其背景花冠颜色相匹配。我们的系统发育比较分析显示，花朵中花粉颜色模式与暴露或隐藏花粉的对比效果，揭示了一种通过视觉隐匿隐藏花粉来防止花粉窃贼的策略。本文受版权保护。版权所有。
Visual signals attractive to friends may also attract enemies. The bright colors of anthers and pollen have generally been thought to attract pollinators. Here we hypothesize that visual crypsis of anthers, and particularly pollen, should be favored in flowering plants because protection from pollen collectors reduces the loss of male gametes. To understand adaptive strategies relating to the color of pollen, we measured the color of pollen, undehisced anther sacs and its background, the corolla, with a spectrometer in 104 insect-pollinated flowering species from a natural community in Hengduan Mountains, southwest China. The colors of anthers, pollen and corollas were diverse in these species. The color diversity of exposed pollen was significantly higher than that of concealed pollen, in which anthers are enclosed or shielded by corollas. The color contrast between pollen and corolla was significantly smaller in species with exposed pollen than in those with concealed pollen. Unlike anther color, exposed pollen color tended to match its background corolla color. Our phylogenetic comparative analysis showed contrasting effects of pollen color pattern in flowers with exposed or concealed pollen, revealing a strategy giving protection from pollen thieves by hiding pollen via visual crypsis.
