This project proposes to explore correlates and determinants of phylogeographic structure and genetic diversity in tropical amphibian species from three model regions, Madagascar, Brazil, and Cuba. We posit the hypothesis that reproductive mode, historical habitat stability and environmental niche breadth are the main determinants of phylogeographic structure of tropical amphibians. To test this hypothesis we will determine DNA sequences of 1 mitochondrial and 3 nuclear gene across the ranges of 6 frog species per model region, reconstruct their phylogeography and genetic diversity within and among populations, model their past and present potential distribution areas and environmental niche breath, and analyze these data in a meta-analyses using a variety of univariate and multivariate statistical procedures. We expect our study to provide conclusive answers on the possible influence of reproductive mode on phylogeographic structure of tropical amphibians and of the correlation of mitochondrial and nuclear gene diversity in these animals, plus numerous indications of other factors possibly correlated with amphibian genetic diversity and speciation that we will thus make accessible for well-focused future studies.

该项目提议探索来自三个模型区域的热带两栖动物物种的植物地理结构和遗传多样性的相关性和决定因素，即马达加斯加，巴西和古巴。我们认为，生殖模式，历史栖息地稳定性和环境利基广度是热带两栖动物植物地理结构的主要决定因素。为了检验这一假设，我们将确定每个模型区域6种青蛙物种的1个线粒体和3个核基因的DNA序列，重建其在人群内和人群中的植物地理学和遗传多样性，模拟其过去和现在的潜在分布区域和环境niche呼吸，并使用元族裔和多种元素进行分析这些数据，并分析这些数据。我们预计我们的研究将提供有关生殖模式对热带两栖动物植物地理结构的可能影响以及这些动物中线粒体和核基因多样性相关性的可能影响的答案，以及其他可能与两栖动物的遗传多样性和我们将使我们可以访问的其他因素相关的其他指示，从而使未来的未来研究都可以访问。
