Comprehensive study on the evolution of pollination mutualisms between Colocasiomyia flies and Araceae plants

为了从进化的角度全面揭示交链孢属和天南星科植物之间的授粉互惠关系，我们对交链孢属的分类、系统发育、生物地理学、生殖生态及其寄主植物的开花/授粉生态进行了研究。结果表明，这一授粉互惠系统具有很大的多样性，为促进授粉，寄主植物通过在花序开花过程中适时地从花序的适当区域释放热量和气味并提供食物奖励来吸引和引导传粉蝇。

To comprehensively reveal pollination mutualisms between Colocasiomyia flies and Araceae plants from a point of evolutionary view, we studied taxonomy, phylogeny, biogeography and reproductive ecology of the genus Colocasiomyia and flowering/pollination ecology of their host plants. As a result, it has been revealed that there is a large diversity in this pollination mutualism system, and that to promote pollination host plants attract and guide pollinator flies by emitting heat and odor and providing food rewards timely from proper regions of inflorescence through flowering process.
