An International Training Workshop on Tropical Soil Properties and Hydrology Linked to Existing Forest Dynamics Projects; Barro Colorado Island, Panama; September 2003

0314581危害这个美洲计划奖将支持一个关于热带森林的结构和动态如何与它们发生的环境的物理特性相关的研讨会。这次会议是由路易斯安那州立大学的凯尔·哈姆斯博士与巴拿马巴尔博亚史密森热带研究所的克里斯蒂安·桑佩尔博士合作组织的。 该讲习班将使来自美国、欧洲和八个热带国家的研究生和高级研究人员聚集一堂，学习和交流有关技术，以确定为长期研究森林多样性和动态而建立的研究地块的土壤和水文特征。 该研讨会将有助于由史密森热带研究所热带森林科学中心（CTFS）协调的NSF资助的正在进行的研究项目，该项目试图将树木多样性与热带土壤，气候和其他物理因素的全球变化联系起来。在森林问题专题小组协调的网络内，目前有15个大型森林动态监测点，拟议的讲习班将使参与整个项目的人员和地理区域增加一倍以上。讲习班的活动将包括：（1）关于热带森林养分循环和水文学理论和背景的晚间讲座和非正式讨论;（2）讨论测量土壤资源的实验设计和取样技术;（3）在巴罗科罗拉多现场实际进行关键土壤和水文分析;和（4）讨论和发展各种新的测量和协议，这些测量和协议可以由每个地点的当地合作者以低成本独立地进行。 因此，拟议的讲习班将促进许多国际参与者参与项目的设计，确保所有地点的数据收集遵循一套统一的方法，并将促进进一步的跨地点比较。

0314581HarmsThis Americas Program award will support a workshop on how the structure and dynamics of a tropical forest are related to physical properties of the environment in which they occur. The meeting is being organized by Dr. Kyle Harms of Louisiana State University, in collaboration with Dr. Cristian Samper of the Smithsonian Tropical Research Institute in Balboa, Panama. The workshop will bring together graduate students and senior researchers from the United States, Europe, and eight tropical countries to learn and exchange techniques aimed at characterizing the soils and hydrology of research plots already established for long-term studies of forest diversity and dynamics. The workshop will contribute to an ongoing NSF-funded research project coordinated by the Center for Tropical Forest Science (CTFS) of the Smithsonian Tropical Research Institute that is attempting to link tree diversity with global variation in tropical soils, climate and other physical factors. There are now 15 large-scale forest dynamics monitoring plots within the network coordinated by CTFS and the proposed workshop will more than double the participation of people and geographic regions in the overall project. Workshop activities will consist of: (1) evening lectures and informal discussions on the theory and background of nutrient cycling and hydrology in tropical forests; (2) Discussions of experimental design and sampling techniques to measure soil-borne resources; (3) Hands-on practice of key soils and hydrological analyses at the Barro Colorado site; and (4) Discussion and development of a variety of new measurements and protocols that could be carried out inexpensively, and independently by local collaborators at each site. Thus the proposed workshop would promote the involvement of many international participants in the design of projects, would ensure that data collection at all sites follows a unified set of methodologies, and would catalyze further cross-site comparisons.
