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-安克雷奇大学和加州大学圣地亚哥分校共同进行的合作研究将检查与南极捕食者个体数量和分布有关的生物和物理特征的鉴定；南极半岛西部生物“热点”的识别和特征；以及在WAP内脊椎动物捕食者消耗磷虾的时间和空间明确模型的发展。它是利用南大洋全球海洋生态系统动力学（SO GLOBEC）实验野外工作过程中获得的数据进行数据综合和建模的几个组成部分之一。SO-Globec是一项多学科合作项目，旨在了解影响南极磷虾（Euphausia superba）生长、繁殖、招募和生存的物理和生物因素。该计划采用多营养水平的方法，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。它目前处于综合和建模阶段。该合作项目关注的是了解捕食者如何利用“热点”，即当地生物生产力密集的区域，以及“热点”如何在时间和空间上结构磷虾捕食率，并将与其他处理水文、初级生产和磷虾动态的综合和建模研究相结合。

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.
