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.

本项目旨在探讨马达加斯加、巴西和古巴三个模式区热带两栖动物物种系统地理结构和遗传多样性的相关因素和决定因素。我们假设繁殖方式、历史生境稳定性和生态位宽度是热带两栖动物系统地理结构的主要决定因素。为了验证这一假设，我们将在每个模型区域确定6种蛙的1个线粒体和3个核基因的DNA序列，重建它们在种群内和种群间的系统地理和遗传多样性，模拟它们过去和现在的潜在分布区域和环境生态位呼吸，并使用各种单变量和多变量统计程序在meta分析中分析这些数据。我们希望我们的研究能够为热带两栖动物的生殖方式对系统地理结构的可能影响以及这些动物的线粒体和核基因多样性的相关性提供结论性的答案，以及可能与两栖动物遗传多样性和物种形成相关的许多其他因素的迹象，从而为未来的研究提供更好的重点。
