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.

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，这是加速物种形成的关键创新。食物植物的毒素将被映射到一个<$total evidence <$重建的Hyles属天蛾（鳞翅目：天蛾科）的繁殖，以推断推定的毒性的原始Hyles食物植物。核基因的分子序列将补充线粒体序列数据，并将在SYNTHESYS与自然历史博物馆（伦敦，英国）的Ian J. Kitching博士合作中编码形态学矩阵。该项目的第二部分将为审查两个复杂问题提供基础：1。幼虫型多态性的遗传基础;一种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标的适用性。这两个问题的一个很好的候选物种是物种H。tithymali。利用现代分子生物学技术，我将研究两个感兴趣的领域的人群中的基因流动：ad 1。人口表现出形态梯度的幼虫形态型的加那利群岛，和广告2。与温带姊妹种H. Euphorphine。
