摘要
棕囊藻Phaeocystissp.独特的生理、生态学特征使它能在不同营养条件、光照强度和温度变化的环境中生长,并且由于受自身的毒性和粘液质的保护使它不能作为摄食者的食物而被大规模摄取,这使它不仅成为高纬度和极地海域一种重要的浮游植物类群,而且在中、低纬度海域它也能旺发,达到非常高的细胞密度,或形成赤潮。棕囊藻对不同生存环境的可塑性,归属于它独特的生理适应性和生理学的某些特点。棕囊藻特有的生物学特征使它在全球范围内高丰度、富分布,对改变整个生态环境存在潜在的威胁,应当引起有关单位的重视。
Global climate and marine environment change creates fit of living environment of Phaeocystis.The characteristics of special physiology and ecology of Phaeocystis make it able to grow on the different environment that changes with temperature,light and nutrient conditions.Because its toxin and the mucilaginous protection,Phaeocystis can't be used as the food to be taken by large grazers.Phaeocystis is one of the most important phytoplankton goup in the high latitude seas, in the low latitude seas but also can form blooms.The environmental plasticity of Phaeocystis survival are attributable to its special physiology adaptability and biochemistry characteristics.Great importance should be attached to that the characteristics of biology can cause to higher abendance and wide distribution of Phaeocystis in the world, and result in potential danger to change the ecological enrionment.
