Research Starter Grant Why mountains

项目摘要

This project will test the hypotheses that mountains have endemic biodiversity in reptile and amphibian fauna because they i) facilitate speciation at a given geographic scale because of topographic and environmental complexity, and ii) provide opportunities for increased population persistence and isolation under climatic fluctuations. This research combines field work in poorly explored highland regions of Brazil, collection data, species distribution models, comparative phylogeography, studies of microhabitat use, and physiological experiments. While generating new and much needed data about a poorly known tropical region and its fauna, this project expands and tests the generality of a process-based method of biodiversity prediction formalized in the PI's postdoctoral work on lowland diversity in Brazil.This project will inform research priorities and conservation in montane regions of the Brazilian Atlantic forest hotspot and provide important baseline data for assessing responses to future climate change. Education and training opportunities to CUNY undergraduate and graduate students will encourage students from underrepresented groups to participate in this project. Collaborations between US and Brazilian institutions will be strengthened and will lead to new advances in science and conservation in Brazil and the tropics.

该项目将测试山脉和两栖动物动物区系具有地方性生物多样性的假设，因为它们i）由于地形和环境的复杂性，并且II）为在气候波动下增加人口持久性和隔离提供了机会。这项研究结合了在不良探索的巴西高地地区，收集数据，物种分布模型，比较植物地理学，微生物使用研究和生理实验的研究中的现场工作。该项目在生成有关一个知名的热带地区及其动物区系的新的和急需的数据时，扩展并测试了基于过程的生物多样性预测方法的普遍性，该方法在PI在巴西低地多样性上的博士后工作中进行了正式的预测。该项目将为Brazilian atlantic Forest contelliment contelliment of Brazilian for Spect and claste and compant contelliment contrace consection consection consection consection consection consection consection consection conselly contelliment contrace and contlace contelly Specot。教育和培训机会使本科生和研究生cuny会鼓励人数不足的团体的学生参加该项目。我们和巴西机构之间的合作将得到加强，并将在巴西和热带地区的科学与保护方面取得新的进步。
