9907950FraserLong-term studies on changes in Antarctic and sub-Antarctic seabird populations are presently emerging as important tools for monitoring the effects of human activity, and for understanding and modeling interactions between climate change and ecosystem responses. Despite research that in some regions now spans five decades, attempts to integrate the existing population data have been limited to qualitative assessments focused primarily on the penguins. This means that the status of many Southern Ocean seabirds remains essentially unknown. Also, for the species whose population status in known, it has not been possible to discern if the trends in evidence are statistically significant. This has created a serious deficiency in our ability to detect and understand the causal factors affecting seabird population and to translate this knowledge into basic and applied research, including the management of Antarctic marine living resources. This award will provide partial support for an international workshop with the following objectives: to identify and catalogue existing long-term data bases on Antarctic and sub-Antarctic seabird populations, to subject the extant data to rigorous statistical analysis with the aim of determining the scope, magnitude and significance of the population trends, and to disseminate the results to relevant Antarctic scientific working groups and the general research community.

目前，对南极和亚南极海鸟种群变化的长期研究正在成为监测人类活动影响以及理解和模拟气候变化与生态系统响应之间相互作用的重要工具。尽管在一些地区的研究已经跨越了50年，但整合现有人口数据的尝试仅限于主要关注企鹅的定性评估。这意味着许多南大洋海鸟的状况基本上仍然未知。此外，对于种群状况已知的物种，尚不可能辨别证据趋势是否具有统计意义。这造成我们在探测和了解影响海鸟数量的因果因素以及将这种知识转化为基础和应用研究，包括南极海洋生物资源管理方面的能力严重不足。该奖项将为一个国际讲习班提供部分支持，其目标如下：确定和编目南极和亚南极海鸟种群的现有长期数据库，对现有数据进行严格的统计分析，以确定种群趋势的范围、幅度和意义，并将结果传播给有关的南极科学工作组和一般研究界。
