Collaborative Research: U.S. SO GLOBEC Synthesis and Modeling - Habitat Utilization and Predator-Prey interactions In Western Antarctic Peninsula

这项由加州大学圣克鲁斯分校、杜克大学、南佛罗里达大学、阿拉斯加大学安克雷奇分校和加州大学圣地亚哥分校共同开展的研究将考察与南极捕食者个体的丰度和分布相关的生物和物理特征的识别；南极半岛西部生物热点的识别和表征；以及脊椎动物捕食者在WAP内对磷虾消耗的时间和空间显式模型的开发。它是使用南大洋全球海洋生态系统动力学(SO GLOBEC)实验现场工作过程中获得的数据的几个数据合成和建模组件之一。SO-GLOBEC是一项多学科努力，重点是了解影响南极磷虾(Euphausia Superba)生长、繁殖、补充和生存的物理和生物因素。该计划使用多营养级别的方法，包括南极磷虾的捕食者和竞争对手，以其他浮游动物、鱼类、企鹅、海豹和鲸目动物为代表。它目前正处于合成和建模阶段。这一合作项目涉及了解捕食者如何利用“热点”，即生物生产力的局部密集区域，以及“热点”如何在时间和空间上构成磷虾捕食率，并将与涉及水文初级生产力和磷虾动态的其他综合和模拟研究相结合。

This collaborative study between the University of California, Santa Cruz, Duke University, the University of South Florida, the University of Alaska-Anchorage, and the University of California, San Diego will examine the identification of biological and physical features associated with the abundance and distribution of individual Antarctic predators; the identification and characterization of biological 'hot spots' within the Western Antarctic Peninsula; and the development of temporally and spatially explicit models of krill consumption within the WAP by vertebrate predators. It is one of several data synthesis and modeling components that use the data obtained in the course of the field work of the Southern Ocean Global Ocean Ecosystems Dynamics (SO GLOBEC) experiment.SO-Globec is a multidisciplinary effort focused on understanding the physical and biological factors that influence growth, reproduction, recruitment and survival of Antarctic krill (Euphausia superba). The program uses a multi-trophic level approach that includes the predators and competitors of Antarctic krill, represented by other zooplankton, fish, penguins, seals, and cetaceans. It is currently in a synthesis and modeling phase. This collaborative project is concerned with understanding how predators utilize 'hot spots', i.e. locally intense areas of biological productivity, and how 'hot spots' might temporally and spatially structure krill predation rates, and will be integrated with other synthesis and modeling studies that deal with the hydrography primary production, and krill dynamics.
