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合作进行的研究将审查与南极洲个别食肉动物的数量和分布有关的生物和物理特征的确定;南极洲西部半岛内生物“热点”的确定和特性;以及脊椎动物捕食者在WAP内磷虾消费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实验实地工作过程中获得的数据进行数据合成和建模的几个组成部分之一，是一项多学科工作，重点是了解影响南极磷虾（南极磷虾）生长、繁殖、补充和生存的物理和生物因素。该计划采用多营养级方法，包括南极磷虾的捕食者和竞争者，以其他浮游动物，鱼类，企鹅，海豹和鲸目动物为代表。 目前正处于综合和建模阶段。这个合作项目关注的是了解捕食者如何利用“热点”，即当地激烈的生物生产力领域，以及“热点”如何可能在时间和空间上结构磷虾捕食率，并将与其他综合和建模研究，处理水文初级生产，磷虾动力学。

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.
