The Antarctic krill, Euphausia superba, is a major component of the Southern Ocean ecosystem, yet little is known about the physiological ecology of this species. This project will examine the degree and consequences of food limitation in the adults and larvae. The response of adults and larvae to long periods of starvation are different; the adults can survive periods of starvation of over a year, whereas the larvae only survive a few months. Experiments will focus on the effect of different food levels on development and growth. A seasonal energy budget will be constructed from data gathered on rates of ingestion, fecal pellet production, growth, molting, reproduction and metabolism. This project will combine laboratory and shipboard measurements to determine the energetics of this important member of the Antarctic marine community.

南极磷虾，南极磷虾，是南大洋生态系统的主要组成部分，但人们对该物种的生理生态知之甚少。 该项目将研究成虫和幼虫食物限制的程度和后果。 成虫和幼虫对长期饥饿的反应是不同的；成虫可以在饥饿中存活一年以上，而幼虫只能存活几个月。 实验将重点关注不同食物水平对发育和生长的影响。 季节性能量预算将根据收集的摄入率、粪便颗粒产生、生长、蜕皮、繁殖和新陈代谢的数据构建。 该项目将结合实验室和船上测量，以确定南极海洋群落这一重要成员的能量。
