7热带飓风日益活跃及气候变化的相关指标:高盐度蓝藻藻垫显示文摘1999年大西洋飓风造成了整个加勒比海和美国大西洋中部沿海地区大面积的环境灾难,但也同时为某些微生物提供了栖息场所,尤其是以蓝藻细菌为主要种群的藻垫。现代的藻垫代表着地球上为人们所知的最古老的生物群落——叠层群落(stromatolites)。当代的藻垫是大西洋飓风所到之处高盐分的巴哈马湖泊的优势生物群落。在巴哈马群岛圣·萨尔瓦多岛的盐湖,我们分析了不同盐度水平如何通过影响光合作用和氮的固定这两个过程来控制藻垫生长的。研究表明,5倍于盐水浓度的高盐度大大抑制了这两个过程,佛罗伊德飕风以及其它风暴所带来的淡水,则缓解了这种抑制作用。在可以遇见的10~40年内,随着大西洋飓风活动的增强,所导致的稀释效应将促进藻垫的繁殖、CO_2的吸收以及养分循环。蓝藻为主要种群的藻垫,将成为气候和生态长期或短期变化的敏感的指示因子。Hans W.Pearl Timothy F.Steppe Kenneth Buchan C.Buchan Malcolm Potts 王利军 2003AMBIO-人类环境杂志2003,32,2:0
8Reverse Gear: Cairo’s Dependence on a Disappearing Paradigm显示文摘In the 1960s and 1970 s, attention was focused on rapid population growth andlarge scale family planning programs were launched in many developing countries.However, the paradigm for understanding fertility decline assumed that exogenoussocioeconomic changes were necessary to reduce family size. By the mid-1990s, thestandard model of the demographic transition had been all but discarded, partly therewere numerous country experiences inconsistent with the model. The 1994 Interna-tional Conference on Population and Development (ICPD) emphasized women’sbroader needs, which were important but were promoted by reducing attention to popu-lation and the need for family planning. The timing of this shift was peculiar, becausethe Cairo proponents were depending on an already discredited model of reproductivebehavior. The policy shift at Cairo undermined the political coalition that had sup-ported international family planning since the 1960s. As a result of declining financialsupport, the health of women has deteriorated seriously in the past decade. Meantime,the countries that have been successful in lifting unprecedented numbers of peopleout of abject poverty were acting independently of the Cairo consensus.Malcolm Potts Martha Campbell 2005Journal of Reproduction and Contraception2005,16,3:0
