项目摘要

This proposal request funding for a workshop to evaluate the state of our understanding of earthworm ecology in North America. The earthworm fauna and their role in ecosystem function in the western hemisphere are poorly known compared with other regions of Earth, especially Europe and Oceania. Although it is widely recognized that earthworms can exert significant influence on physical, chemical and biological processes in soils, it is not clear how generally results from other biogeographic regions apply to ecological conditions and earthworm assemblages (particularly native earthworm fauna) prevalent in North America. The focus of this workshop will be on the influence of earthworms on soil processes in forest, rangeland and crop ecosystems over the range of climatic and soil conditions that occur in North America, including Canada and Alaska, the continental U.S., Mexico, and the Caribbean islands. Investigators from each region will be invited to participate (total of ca. 30 people). Objectives are to evaluate our current understanding and to chart future research needs in four topic areas: 1) systematics and biodiversity; 2) biogeography 3) ecosystem processes; and 4) management implications. The final product of the workshop will be a peer- reviewed volume containing final position papers in each topic area and short contributions based on poster presentations. This volume will be a state-of-the-art resource for research, teaching and application.

本提案要求为一个研讨会提供资金，以评估我们对北美蚯蚓生态学的了解状况。与地球其他地区，特别是欧洲和大洋洲相比，西半球的蚯蚓区系及其在生态系统功能中的作用鲜为人知。虽然人们普遍认识到蚯蚓可以对土壤中的物理、化学和生物过程产生重大影响，但尚不清楚其他生物地理区域的一般结果如何适用于北美普遍存在的生态条件和蚯蚓组合（特别是本地蚯蚓动物群）。本次研讨会的重点将是蚯蚓对北美气候和土壤条件范围内森林、牧场和作物生态系统土壤过程的影响，包括加拿大和阿拉斯加、美国大陆、墨西哥和加勒比岛屿。将邀请各地区的调查人员参加（共约30人）。目标是评估我们目前的认识，并在四个主题领域绘制未来的研究需求：1)系统学和生物多样性；2)生物地理学3)生态系统过程；4)管理意义。研讨会的最终成果将是一本同行评议的卷，其中包含每个主题领域的最终立场文件和基于海报展示的简短贡献。这本书将是一个最先进的研究，教学和应用资源。
