Demography and Ecophysiology of Regeneration of Tropical Rain Forest Trees

这项研究的目的是检查模式， 热带湿林树种的生长和存活，以及 以确定最影响这些模式的因素。 该项目是一个长期的，多学科的 林冠和挺水树种多样性研究 在哥斯达黎加热带潮湿森林（La Selva生物 热带研究组织（Organization for Tropical Studies）。 的这一阶段 这项研究将集中在植物种群过程， 幼树和成株对光合和生长的响应 环境条件和森林一级的评价 光环境。 电子光传感器和新技术 森林冠层的计算机分析将用于 测量光的分布和变化， 树木在再生过程中 还将收集以下数据： 的生理特性（光合能力） 具有已知生长和光照历史的树苗和成年树 环境 这种综合信息对于以下方面至关重要： 了解和管理热带森林， 只有结合来自不同领域的专业知识。

The purpose of this research is to examine patterns of growth and survivorship of tropical wet forest tree species, and to determine the factors which most influence these patterns. This project is a continuation of a long-term, multidisciplinary study of a diverse spectrum of canopy and emergent tree species in a Costa Rican Tropical wet forest (the La Selva Biological Station of the Organization for Tropical Studies). This phase of the research will focus on plant population processes, photosynthetic and growth responses of saplings and adults to environmental conditions, and forest-level evaluation of the light environment. Electronic light sensors and new techniques for computerized analysis of the forest canopy will be used to measure the distribution and variation in light availability to the trees during regeneration. Data will also be gathered on the physiological characteristics (photosynthetic capacity) of saplings and adults with known histories of growth and light environment. Such integrated information is critical for understanding and managing tropical forests, and can be obtained only by combining expertise from different fields.
