Fauth & Resetarits 9727039 & 9727543 Ecologists have long been interested in understanding the factors controlling the abundance and distribution of species and particularly concerned about identifying the processes controlling species diversity. This project focuses on understanding species diversity in Anuran communities in temporary ponds in coastal and sandhill regions of the Southeastern US, habitats with the highest levels of diversity for these organisms outside of the tropics. Despite substantial earlier work, there is little understanding of the factors that influence the high diversity of these communities under natural situations. This work will test a model of amphibian species richness in Southeastern temporary ponds using a series of replicated whole-pond experiments. Ultimately, the model will be further developed and refined to include other taxa and systems. This research will also address one of the most common criticisms of previous investigations of these amphibian communities. Much earlier work has been conducted in artificial habitats and little effort has been made to relate this work to processes occurring in natural ecosystems. Through its use of experimental manipulations of natural temporary ponds, this project will address this fundamental concern. Ultimately it will be able to test the extent to which mesocosm experiment that are designed primarily to test general or specific ecological theories can simultaneously describe in detail and make specific predictions about the structure and dynamics of natural communities. This work will have important implications for both basic ecology and conservation biology. It will help to identify the factors that have maintained high Anuran diversity in Southeastern habitats while substantial reductions of amphibian species have been noted elsewhere in the US.

Fauth重置 9727039 9727543 长期以来，生态学家一直对了解控制物种丰度和分布的因素感兴趣，特别关注确定控制物种多样性的过程。该项目的重点是了解美国东南部沿海和沙丘地区临时池塘中无尾两栖动物群落的物种多样性，这些生物在热带以外的栖息地具有最高的多样性水平。 尽管大量的早期工作，有很少的理解的因素，影响这些社区的高度多样性的自然情况下。 这项工作将测试两栖动物物种丰富度模型在东南临时池塘使用一系列复制的全池塘实验。 最终，该模型将进一步发展和完善，以包括其他分类群和系统。 这项研究还将解决以前对这些两栖动物群落的调查中最常见的批评之一。 许多早期的工作是在人工生境中进行的，很少有人努力将这项工作与自然生态系统中发生的过程联系起来。 通过对天然临时池塘的实验性操作，该项目将解决这一基本问题。 最终，它将能够测试主要用于测试一般或特定生态理论的中尺度实验在多大程度上可以同时详细描述和对自然群落的结构和动态做出具体预测。 这项工作将对基础生态学和保护生物学产生重要影响。 这将有助于确定在美国东南部栖息地保持高无尾两栖动物多样性的因素，而在美国其他地方已经注意到两栖动物物种的大幅减少。
