Understanding the marine ecosystem dynamic in different environmental characteristics

气候变化对海洋生态系统的影响是近年来备受关注的问题之一。然而，对大面积海洋生态系统的连续监测在后勤上是困难的。在这项研究中，生物热点被确定从觅食区的远洋海鸟，条纹剪，在不同的海洋环境（亚热带，温带，亚北极）使用微型数据记录仪。然后，研究了这些热点的特点。利用觅食环境的关系，统计模型（即栖息地建模），建立了使用广义加性模型，以预测其对预期的水温里泽情景的响应。从这些结果来看，觅食行为的条纹剪切水可以是一个指标（或监测）的海洋生态系统的动态在日本。

The effect of climate-related changes on marine ecosystem has been one of the recent concerned issues. However, the continuous monitoring of marine ecosystem over large area is logistically difficult. In this study, the biological hotspots were identified from foraging areas of a pelagic seabird, streaked shearwaters, in different marine environment (subtropical, temperate, subarctic) using miniturized data-loggers. Then, the characteristics of these hotspots were examined. Using the foraging-environment relationship, statistical models (i.e. habitat modelling) were established using the generalized additive model to predict their responses to the expected water temperature rize scenario. From these results, the foraging behaviour of streaked shearwaters can be an indicator (or monitor) of marine ecosystem dynamics around Japan.
