U.S.-France Workshop: Causes, Consequences and Mechanisms of Dispersal at the Individual, Population and Community Level, April 24-May 1, 1999, Roscoff, France

该奖项将支持美国参加于1999年4月24日至5月1日在法国罗斯科夫举行的关于个体、种群和社区层面上扩散的原因、后果和机制的美法研讨会。大约10名美国人和15名欧洲人（主要是法国科学家）将参加这次研讨会。提议的研讨会的目的是讨论和合并科学家在分散的各个方面的观点。它将集中于(1)研究扩散的方法；(2)扩散原因多；(3)分散的行为机制；(4)个体、种群和物种水平上的扩散后果；(5)从基因流动和局部适应的角度研究扩散的前景。扩散是人类应对栖息地破碎化和全球气候变化带来的环境威胁的重要生存行为。一个物种在这种变化中幸存下来的可能性很大程度上取决于它在环境中转移的能力，要么是通过在栖息地之间移动，要么是通过迅速适应当地条件。这种行为对所有物种的重要性为本次研讨会提供了动力。预计研讨会的结果将导致这一领域的合作和未来的研究。

Approximately 10 Americans and 15 Europeans, chiefly French scientists, will participate in the workshop. The aim of the proposed workshop is to discuss and merge the perspectives of scientists working on various aspects of dispersal. It will focus on (1) methods for studying dispersal; (2) the multiple causes of dispersal; (3) the behavioral mechanisms involved in dispersal; (4) the consequences of dispersal at the individual, population and species levels; and (5) perspectives for the study of dispersal in terms of gene flow and local adaptation. Dispersal is an important survival behavior in response to environmental threats posed by habitat fragmentation and global climate change. The probability of a species surviving such changes is strongly dependent on its ability to tract shifts in the environment, either by moving between patches of habitat or by rapidly adapting to local conditions. The importance of this behavior to all species provides the motivation for this workshop. It is anticipated that the results of the workshop will lead to collaborations and future research in this area.
