Phylogeny and chemicals ecology of Hyles hawkmoths (Lepidoptera, Sphingidae) with special reference to the Hyles euphorbiae complex

本研究项目的第一部分旨在评估草食动物强大的解毒能力，这是导致物种加速形成的关键创新。食用植物的毒素将被绘制在海鞘属(鳞翅目：天蚕科)鹰蛾的系统发育重建中，以推断原海鞘食用植物的假定毒性。核基因的分子序列将补充线粒体序列数据，形态矩阵将在与自然历史博物馆(英国伦敦)的Ian J.Kitching博士合作的合成系统中进行编码。该项目的第二部分将为研究两个复杂问题提供基础：1.幼虫模式多态的遗传基础；2.多功能嗜热动物作为全球变暖对欧洲动物群影响的生物指示器的适用性。这两个问题的一个很好的候选物种是H.tihyali。利用现代分子生物学技术，我将研究两个感兴趣地区的种群中的基因流：公元1。加那利群岛上表现出幼虫形态类型梯度的种群，以及公元2.几个与其温带姊妹种--胡麻黄蛾(H.euphorbiae)的渐渗带。

The first part of this research project aims at an evaluation of strong detoxification abilities of herbivores acting as a key innovation causing accelerated speciation. The toxins of the foodplants will be mapped onto a ¿total evidence¿ reconstruction of the phylogeny of the hawkmoths of the genus Hyles (Lepidoptera: Sphingidae) to infer the putative toxicity of the proto- Hyles foodplant. Molecular sequences of nuclear genes will supplement mitochondrial sequence data and a morphological matrix will be coded in a SYNTHESYS cooperation with Dr. Ian J. Kitching at the Natural History Museum (London, UK). The second part of the project will provide the foundation for the examination of two complex issues: 1. The genetic basis of larval pattern polymorphism, and 2. The applicability of a versatile thermophilic animal as a bio-indicator of the impact of global warming on European fauna. A good candidate species for both questions is the species H. tithymali. With modern techniques of molecular biology I will examine the gene flow in populations of two areas of interest: ad 1. the population showing a morphological gradient of larval morphotypes on the Canary Islands, and ad 2. several introgression zones with its temperate sister species, H. euphorbiae.
