Establishment of metacommunity approach toward conservation of coastal biological community in varying environment

为了给沿海生态系统和资源的保护与管理提供科学依据，本研究采用综合方法研究了沿海海洋群落的结构、动态及其与全球气候变化（如气温上升）的关系。我们特别针对海草床，岩石潮间带和海带森林群落作为模型系统。基于定期普查、遥感和GIS分析、元群落结构统计分析、基于分子数据的遗传分析和野外操作实验，对这些群落进行了大规模、长期的监测。结果表明，海岸带群落结构受不同空间尺度的多种因素的影响，其动态可能会随着气候变化而不稳定，这主要是通过改变生产者和消费者之间的物种相互作用过程实现的。

To provide scientific information for the conservation and management of coastal ecosystems and resources, the present study carried out an integrated approach to investigate structure and dynamics of coastal marine community and their changes in relation to global climate change such as temperature rise. We specially targeted on seagrass bed, rocky intertidal and kelp forest communities as model systems. We conducted broad-scale, long-term monitoring of these communities based on periodical census and the use of remote sensing and GIS analyses, statistical analyses on meta-community structure, genetic analyses based on molecular data, and field manipulative experiments. The results demonstrated that structures of coastal communities are affected by multiple factors that operate at different spatial scales, and that their dynamics can be unstable with ongoing climate change through modification of species interaction processes between producers and consumers.
