RUI:LTREB: Enhancement and Dissemination of Long-term Datasets on Tropical Montane Forest Nutrient Dynamics in Monteverde, Costa Rica

9615341 Nadkarni相对于许多其他栖息地和生态系统组成部分，对热带云雾林及其冠层群落的长期生态过程了解甚少。拟议研究的主要目标是以过去十年在哥斯达黎加蒙特韦尔德云雾森林保护区收集的一套独特数据为基础。拟议的工作包括测试两个假设的作用，冠层成分在森林养分循环和动态。他们将解决的过程，让活的和死的树冠组件作为营养电容器在这片森林中有效地捕获同种异体的大气营养物质，保留在树冠，然后将它们转移到其他生态系统的部分。这项研究还将支持参与正在进行的关于凋落物和树干分解的长期多地点研究。预期成果包括热带云雾林和林冠生态学长期方面的新信息，十多年现场描述，实验和建模工作的综合，以及与蒙特韦尔德地区正在进行的研究，教育和保护活动的整合。

9615341 Nadkarni Long-term ecological processes in tropical cloud forests and their canopy communities are poorly understood relative to many other habitats and ecosystem components. The major objective of the proposed research is to build upon a unique set of data that has been gathered over the past decade at the Monteverde Cloud Forest Reserve in Costa Rica. Proposed work includes testing of two hypotheses concerning the role that canopy components play in forest nutrient cycling and dynamics. They will address processes that allow live and dead canopy components to serve as nutrient capacitors in this forest by efficiently capturing allogenic atmospheric nutrients, retaining them in the canopy, and then transferring them to other ecosystem parts. This research will also support participation in the ongoing long-term multi-site study of litter and stem decomposition. Anticipated results include new information on long-term aspects of tropical cloud forest and canopy ecology, synthesis of more than a decade of descriptive, experimental, and modeling work at the site, and integration with ongoing research, educational, and conservation activities in the Monteverde region.
