Workshop: Food Web Structure and Dynamics in Marine, Terrestrial and Freshwater Environments, Summer 1995 at Cornell University

9510113 Solow这一拟议的努力将举办为期4周的暑期学校讲习班，这是专门比较海洋、陆地和淡水生态系统的一系列讲习班中的第四个，重点是食物网结构和动态。食物网代表了不同类型生物之间的摄食关系，是生态学核心主题的一部分。食物网理论和数据对于处理许多具有社会重要性的环境问题至关重要;水质，海洋和淡水渔业，物种保护，全球气候变化，农业生态系统和有毒物质的移动。食物网的三个基本特征是结构、动态以及与物理和化学环境的关系。虽然这些特征还远未被理解，但经验和理论生态学家正在迅速建立一套描述性数据和可检验的理论。拟议的课程将包括一系列讲座，重点放在这些领域的基础理论。这将为更专业的讲座提供基础。这些讲座将涉及其他关键问题，包括食物网的间接影响，不同类型环境中食物网的差异，以及将食物网理论应用于陆地，海洋和淡水生态系统中的一些环境问题。

9510113 Solow This proposed effort will conduct a 4-week summer school workshop, the fourth in a series devoted to comparisons of marine, terrestrial and freshwater ecosystems, to focus on food web structure and dynamics. Food webs represent the feeding relationships between various types of organisms and are part of the core subject matter in ecology. Food web theory and data are crucial to dealing with many environmental issues of social importance; water quality, marine and freshwater fisheries, species conservation, global climate change, agroecosystems, and the movement of toxic materials. Three basic features of food webs are there structures, their dynamics, and their relationships to the physical and chemical environment. Although these features are still far from being understood, empirical and theoretical ecologists are rapidly building up a body of descriptive data and testable theory. The proposed course will include a series of lectures focused on the fundamental theory in each of these areas. This will provide a basis for more specialized lectures. These lectures will address other key issues, including indirect effects in food webs, differences between food webs in different types of environments, and the application of food web theory to a number of environmental problems in terrestrial, marine and freshwater ecosystems.
