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，但积冰运动和光周期的季节性模式很明显。近海生物系统的燃料是上升的、营养丰富的、深环极地的水，这支持了南极南半球夏季丰富的初级生产力。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中发现的动植物的描述。关于这些生物群如何在这样的极端环境中生活和相互作用的更基本的方面已经被研究。这种独特的海洋环境提供了一个机会，可以就南极洲丰富多样的海洋生物的生物学方面举行一次基础广泛的专题讨论会。该项目将支持将在综合和比较生物学学会2000年1月会议上举行的“南极海洋生物学”专题讨论会。一般性专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、大型海洋生物的光热驯化战略、海洋无脊椎动物的生理和发育以及鱼类抗冻剂的起源和进化。这些陈述的综合性和可比性将具有广泛的科学吸引力。这些会议记录将通过发表在《美国动物学家》杂志上向普通科学界公布。

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.
