摘要

认知能力在生态群落的背景下进化。蜜蜂和大黄蜂已经成为认知生态学的模型系统,但授粉是由不同的昆虫群体在类似的压力下进行的,以有效地在混合花卉群落中觅食。在一个岛屿植物群落中,研究了6种膜翅目昆虫(2种群居大黄蜂、1种杜鹃大黄蜂、2种黄蜂和1种切叶蜂)的颜色学习能力。利用野外昆虫访花记录,确定了岛屿植物-传粉媒介网络中各物种的专门化指数,并测量了它们访花的光谱反射率。在我们的植物传粉者网络中,专业化指数较高的物种在颜色学习任务中的正确选择比例高于通才物种。更多面手的物种也在膜翅目动物的色彩视觉空间中访问了一组彼此更相似的花。这些结果表明,较好的颜色学习能力可能使昆虫能够在不同颜色的植物上觅食,而更多的通才昆虫会访问颜色相似的花朵,因此较少依赖于重复的颜色学习来有效地觅食。

Pollinator cognition in a plant network.

Cognitive abilities evolve within the context of ecological communities. Honeybees and bumblebees have become model systems for cognitive ecology, but pollination is performed by a diverse group of insects under similar pressures to forage efficiently in a mixed floral community. We studied the colour learning abilities of six species of Hymenoptera (two eusocial bumblebees, a cuckoo bumblebee, two wasps and a leaf-cutter bee) within the context of an island plant community. We used records of insect visits to flowers in the field to determine the index of specialization of each species in the island plant-pollinator network, and measured the spectral reflectance of the flowers they visit. Species with higher specialization indices in our plant-pollinator network made a larger proportion of correct choices in a colour learning task than more generalist species. The more generalist species also visited a group of flowers more similar to each other in hymenopteran colour vision space. These results indicate that better colour learning abilities may enable insects to forage on plants of different colours, whereas more generalist insects are visiting flowers that are similar in colour, and therefore are less reliant on repeated colour learning to forage efficiently.

期刊介绍: Previously a supplement to Proceedings B, and launched as an independent journal in 2005, Biology Letters is a primarily online, peer-reviewed journal that publishes short, high-quality articles, reviews and opinion pieces from across the biological sciences. The scope of Biology Letters is vast - publishing high-quality research in any area of the biological sciences. However, we have particular strengths in the biology, evolution and ecology of whole organisms. We also publish in other areas of biology, such as molecular ecology and evolution, environmental science, and phylogenetics.
