Workshop: Biological Diversity and Ecosystem Function: Islands as Model Systems; The Bahamas; October 1993

9310767 Vitousek生物多样性的丧失是人类人口和活动水平不断扩大的许多全球性后果中最持久的。 这种多样性的丧失在多大程度上导致生态系统功能的变化？ 二十多年前，生态学界认为我们知道这个问题的答案多样性导致生态系统的稳定，因此多样性的丧失会使生态系统失去稳定性。 然而，当时我们对多样性和生态系统功能的理解甚至不足以以有意义的方式提出这个问题。 生态学的进步，（在种群生物学和生态系统研究方面）以及迫切需要了解生物多样性正在发生的全球变化的后果，促使环境问题科学委员会（SCOPE）建立了一个为期三年的项目，以评估a）生物多样性与生态系统功能之间的联系;和B）现在应该启动什么样的研究，以便我们将来能够理解和管理这些联系。 这项建议要求提供经费，以支助在科学范围方案内举办一个讲习班，评价生物多样性和生态系统;讲习班将于1993年10月中旬在巴哈马举行。 有助于我们理解C4生态系统的发展。根据优秀的评论，该计划同意这一评估，并建议为该提案提供资金。 潘基文·贝蒂将这一提议评为“公平”。她认为这项研究非常重要，PI是高素质的，但这项研究更“geol”。 ! ! !

9310767 Vitousek The loss of biological diversity if the most permanent of the many global consequences of an expanding human population and level of activity. To what extent does this loss of diversity lead to changes in the functioning of ecosystems? Twenty and more years ago, the ecological community thought we knew the answer to this question-diversity leads to ecosystem stability, and its loss therefore should de stabilize ecosystems. However, at that time our understanding of both diversity and ecosystem function were inadequate even to frame the question in a meaningful way. %%% The advances in ecology since (both in population biology and ecosystem studies) and the urgent need to understand the consequences of ongoing global changes in biological diversity have led the Scientific Committee on Problems of the Environment (SCOPE) to establish a 3-year project to evaluate a)what is known about connections between biological diversity and ecosystem function; and b) what research should be initiated now so that we will be able to understand and manage these connections in the future. This proposal requests funding to support a workshop within the SCOPE program to evaluate biological diversity and ecosystems; the workshop will be held in mid-October, 1993, in the Bahamas. ibute to our understanding of the development of C4 ecosystems. Based on the excellent reviews, the Program agrees with this assessment, and recommend that this proposal be funded. Panelist Beatty rated this proposal as "Fair." She believed that the research was very important and that the PI was highly qualified, but that the study w as much more "geol ! ! !
