北极的气候变化和紫外辐射水平的变化将具有深远的影响,会影响各营养级的水生物种、构成其生境的物理和化学环境以及作用于淡水生态系统和其内部的过程。诸如温度和降水之类的气候变量与淡水生态系统的相互作用高度复杂并能够以难以预测的方式在生态系统中蔓延。这部分是由于对北极淡水生态系统及其与气候和其他环境变量的相互关系缺乏了解,同时也由于北极地区缺乏长期的淡水监测点和综合的水文—生态学研究计划。本专刊中的文章是25名国际专家和他们各自的网络关于北极淡水水文学和相关的水生生态系统进行的分析的摘要,该摘要最初在2005年作为北极气候影响评估(ACIA)的"第8章——淡水生态系统和渔业"发表。这些文章广泛地概述了北极各种淡水系统的一般水文学和生态学特征,包括对每一个ACIA地区的描述,后面回顾了全新世期间淡水系统的历史变化。接着是气候变化对大尺度水文生态学、水生生物和生态系统结构和功能,以及北极鱼类和渔业影响的评估。还讨论了潜在的增效效应和累积效应以及紫外辐射和污染物的作用。文章利用环北极地区的案例研究结果说明了许多影响的性质和复杂性,以及重要的临界响应(即:那些产生分阶段影响和/或非线性影响的响应)。本期最后总结了关键的发现,并列举了科学认识方面的空白,以及与政策有关的建议。

引言总的来讲，北极地区气候和紫外辐射的变化将会产生深远的影响，其影响主要作用于不同营养级的水生物种，作为水生生物生境的自然环境及其化学性质，对水生生态系统起作用的进程和水生生态系统自身的进程。气候变量，例如气温和降水，与淡水生态系统的交互作用非常复杂，而且这种作用可以通过生态系统以某些不易察觉的方式扩散。系统的复杂性使准确预测气候和紫外辐射变化对淡水系统的影响增加了难度，尤其是那些跳跃式或非线形的临界反应，更难把握。由于缺乏对北极淡水系统与气候及其他环境变量之间的相互影响关系的了解，加上北极地区非常稀少的长期淡水监测站点和综合水文生态研究项目，我们的预测能力受到进一步的限制。

各类基于生态系统的气候替代数据一直用于评估北极过去的变化。虽然由于河流物质的持续性重新建构使流水生态系统的记录相对缺乏,但可通过高质量静水生态系统数据的组合,回溯到环北极地区的更新世末期和冰川消失时期。总之,可以部分地归因于冰川覆盖收缩效应的变化引起的全新世的气候变化,使北极的水文和淡水生态系统产生了重要的时空变化。特别值得注意的是,在长期的润湿时期,北部泥炭地得到了大规模扩展。较近期的湖泊生物区和沉积学数据揭示了在过去1～2个世纪期间出现的一般性气候变暖趋势,并且表明了淡水特征,譬如冰盖持续时间和热量层化的主要变化。这些数据为预测和量测气候变化对未来的影响提供了一个极好的依据基线。

The first stars in the early Universe were formed about 400 million years after the big bang. Verification of the existence of these stars is important for our understanding of the evolution of the Universe[1]. It has been predicted that for Population-III stellar production yields, the abundances of odd-Z elements are remarkably deficient compared to their adjacent even-Z elements[2]. Astronomers are searching for long-lived, low mass stars with the unique nucleosynthetic pattern matching the predicted yields[3].

一些气候驱动变量(如气温和降水量)的预期变化与北极的淡水生态系统和生物区系有很大的相关性。这些将对那里当前的生态系统和鱼类产生许多直接和间接的影响。预期鱼种群的变化总体上是从正面到负面,随鱼种而不同,相同鱼种不同种群也有差异,取决于鱼种的生物学特性和耐受力。在当地水域内,鱼种群的变化是综合的。这会对未来北极的淡水鱼和河海洄游性鱼类带来大范围的可能性。由于缺乏北方地区鱼类生物学与生境相互作用方面的基本知识,加上未来气候预测的尺度问题和不确定性,大多数案例研究只能给出那些定性情景。这限制了在北极应对气候变化对鱼类和渔业影响所做的一些准备。
