Antarctic Marine Biology: Symposium, to be held January 4-8, 2000

南极海洋环境的特点是水温持续较低，但有明显的浮冰运动和光周期的季节性模式。近海生物系统由上涌的、营养丰富的深环极水提供燃料，这支持了南极南部夏季丰富的初级生产。虽然南极海洋生物学是一门相对年轻的科学，但研究已经远远超出了对南极水域发现的动植物的描述。这些生物群如何在如此极端的环境中生存和相互作用的更基本方面已经得到了研究。这种独特的海洋环境提供了一个机会，就南极洲丰富多样的海洋生物的生物学方面举办一次基础广泛的研讨会。该项目将支持在综合与比较生物学学会2000年1月会议上举行的“南极海洋生物学”专题讨论会。将讨论的一般主题包括海洋微生物过程，海冰微藻的生理学，磷虾，海豹和企鹅的能量学和繁殖，大型动物的光热适应策略，海洋无脊椎动物的生理学和发育以及鱼类防冻的起源和演变。报告的综合和比较性质将具有广泛的科学吸引力。会议记录将在《美国动物学家》杂志上发表，供广大科学界查阅。

The antarctic marine environment is characterized by constant, low water temperatures yet marked seasonal patterns of pack-ice movement and photoperiod. The offshore biotic system is fueled by upwelled, nutrient-rich, deep circumpolar water, which supports rich primary production during the Antarctic austral summer. Although antarctic marine biology is a relative young science, research has gone far beyond descriptions of plants and animals found in antarctic waters. More fundamental aspects of how these biota live and interact in such an extreme environment have been studied. This unique marine environment provides an opportunity to present a broadly based symposium on aspects of the biology of the rich and diverse marine life in Antarctica. This project will support a symposium on "Antarctic Marine Biology" to be held at the January, 2000 meeting of the Society of Integrative and Comparative Biology. General topics to be addressed include marine microbial processes, physiology of sea ice microalgae, the energetics and reproduction of krill, seals and penguins, strategies of photothermal acclimation in macroalge, the physiology and development of marine invertebrates and the origin and evolution of fish antifreezes. The integrative and comparative nature of the presentations will have broad scientific appeal. The proceedings will be available to the general scientific community through publication in the American Zoologist.
