International Dissertation Enhancement: Interactive Effects of Harvest, Grazing and Fire on Plant Populations and Communities in the Western Ghats, India.

01104989 Ticktin/丽莎曼德尔这个博士论文增强奖提供资金的最后一次前往印度的coPI曼德尔进行一套额外的实地测量为她的论文研究。 该研究的重点是收获，放牧和火灾对印度主要生物多样性地点收获的棕榈种群动态的相互作用？在西高止山脉，人类活动强烈影响当地的植物群落。虽然以前已经做了一些棕榈叶收获的人口影响的研究，这项研究通过新的统计人口建模技术的应用，打破了新的知识基础。 多中心比较研究与明确的实验研究相结合，将加强coPI？的论文。 在西高止山脉等热带地区，研究本地植物种群与人类活动之间的关系尤其有价值。在这个项目中学到的东西可能是实际适用的地方和模型方法，在许多类型的网站，特别是在热带地区的研究。该项目的更广泛的影响是强大的国家之间的交叉互动的水平，在该领域的印度同事和当地人民的纳入，以及它的潜力，开发新的建模和实验方法，植物保护工作在面对重大的持续人类活动。 这一增强为当前NSF研究生研究奖学金获得者的国际研究提供了额外的资金。

01104989Ticktin/Lisa MandleThis Doctoral Dissertation Enhancement award provides funding for a final trip to India for coPI Mandle to carry out a suite of additional field measurements for her dissertation research. The focus of the study is the interactive effects of harvest, grazing, and fire on the population dynamics of a harvested palm in a prime biodiversity site in India?s Western Ghats, where human activities strongly impact native plant communities. Although a number of studies of demographic effects of palm leaf-harvest have been done previously, this study breaks new intellectual ground through the application of new statistical population modeling techniques. The combination of multi-site comparative studies with explicit experimental studies will strengthen the coPI?s thesis. Research focused at the nexus between native plant populations and human activities is especially valuable in tropical sites such as the Western Ghats. What is learned in this project could potentially be both practically-applicable locally and a model approach for such research at many types of sites, particularly in the tropics. The broader impacts of this project are strong with respect to the level of cross-interaction between countries, the incorporation of Indian colleagues and local people in the field, as well as its potential to develop new modeling and experimental approaches for plant conservation efforts in the face of significant on-going human activities. This enhancement provides additional funding for international research to a current NSF Graduate Research Fellowship awardee.
