SGER: Biocomplexity associated with controls of sensitivity and stability in tundra systems over decadal time scales.

将召开为期5天的研讨会，探讨生物复杂性如何在十年时间尺度上控制苔原系统的敏感性和稳定性。该领域的专家将被邀请发表主题演讲，参与评估现有知识，并准备一项科学计划，以确定研究冻土带系统复杂性、功能和动态的研究途径。与气候和苔原有关的五个主题和主要问题将在多个时空尺度上进行讨论。这包括变革的驱动因素；变化的模式；对变化的敏感性；对变化的反应；以及变化的含义。本次研讨会将汇集参与北美冻土带实验（NATEX）的科学家，该实验是被称为国际冻土带实验（ITEX）的更大科学家网络的一部分。ARCSS计划支持ITEX工作，作为陆地-大气-冰相互作用（LAII）组件的一部分。为了加强国际和学生的参与，将举行实时视频网络广播和电话会议。这些广播将被转发到科学支持联合办公室，最终纳入ARCSS数据协调中心。将编写和分发一份综合报告。在研讨会期间确定的关键人员将起草一份类似于LAII科学计划的科学计划，并将包括北极陆地系统生物复杂性相关研究的大纲。计划在适当的国际公认期刊上发表一份手稿。

A 5-day symposium will be convened to explore how biocomplexity controls the sensitivity and stability of tundra systems over decadal time scales. Experts in the field will be invited to give keynote presentations and participate in appraising existing knowledge and prepare a science plan to identify avenues of research examining the complexity, function and dynamics of tundra systems. Five themes and primary questions related to climate and the tundra will be addressed across multiple spatial and temporal scales. This includes drivers of change; patterns of change; sensitivity to change; responses to change; and implication of change. This symposium will bring together scientists involved in the North American tundra Experiment (NATEX) that is part of a larger network of scientists known as the International Tundra Experiment (ITEX). The ARCSS program supports ITEX work as part of the Land-Atmosphere-Ice Interactions (LAII) component. To enhance international and student participation, real time video web casting and teleconferencing will take place. These broadcasts will be forwarded to the Joint Office of Scientific Support for ultimate inclusion in the ARCSS Data Coordination Center. A synthesis report will be prepared and circulated. Key personnel identified during the symposium will draft a science plan similar to the LAII science plan and will include an outline for biocomplexity related research in Arctic terrestrial systems. A manuscript for publication in an appropriate internationally recognized journal is planned.
