Carbon sinks in mangroves and their implications to carbon budget of tropical coastal ecosystems

Nearly 50% of terrigenous materials delivered to the world's oceans are delivered through just twenty-one major river systems. These river-dominated coastal margins (including estuarine and shelf ecosystems) are thus important both to the regional enhancement of productivity and to the global flux of C that is observed in land-margin ecosystems. The tropical regions of the biosphere are the most biogeochemically active coastal regions and represent potentially important sinks of C in the biosphere. Rates of net primary productivity and biomass accumulation depend on a combination of global factors such as latitude and local factors such as hydrology. The global storage of C in mangrove biomass is estimated at 4.03 Pg C; and 70% of this C occurs in coastal margins from 0° to 10° latitude. The average rate of wood production is 12.08 Mg ha^?1 yr^?1, which is equivalent to a global estimate of 0.16 Pg C/yr stored in mangrove biomass. Together with carbon accumulation in mangrove sediments (0.02 Pg C/yr), the net ecosystem production in mangroves is about 0.18 Pg C/yr. Global estimates of export from coastal wetlands is about 0.08 Pg C/yr compared to input of 0.36 Pg C/yr from rivers to coastal ecosystems. Total allochthonous input of 0.44 Pg C/yr is lower than in situ production of 6.65 Pg C/yr. The trophic condition of coastal ecosystems depends on the fate of this total supply of 7.09 Pg C/yr as either contributing to system respiration, or becoming permanently stored in sediments. Accumulation of carbon in coastal sediments is only 0.41 Pg C/yr; about 6% of the total input. The NEP of coastal wetlands also contribute to the C sink of coastal margins, but the source of this C is part of the terrestrial C exchange with the atmosphere. Accumulation of C in wood and sediments of coastal wetlands is 0.205 Pg C/yr, half the estimate for sequestering of C in coastal sediments. Burial of C in shelf sediments is probably underestimated, particularly in tropical river-dominated coastal margins. Better estimates of these two C sinks in the tropics, coastal wetlands and shelf sediments, is needed to better understand the contribution of coastal ecosystems to the global carbon budget.     

常见儿科病红细胞免疫粘附功能检测的临床意义

检测儿科常见疾病患者中的红细胞免疫粘附功能发现：（１）新生儿的红细胞免疫粘附功能尚未发育完善，低于正常儿童水平；（２）急性肾炎患儿的红细胞免疫粘附功能呈现继发性增强；（３）肾病综合征、风湿性疾病、大叶性肺炎、秋季腹泻及急性白血病等患儿的红细胞免疫粘附功能呈继发性降低；（４）红细胞免疫粘附功能的变化与疾病的发展及转归有关。提示在儿科疾病的诊断和治疗中观察患儿的红细胞免疫粘附功能有重要意义。     

热胁迫对辣椒花粉发育及其生活力的影晌

用光学和荧光显微镜及扫描电镜观察等方法，研究了热胁迫对辣椒花粉形成发育、生活力、萌发率及雌性系统的影响。发现辣椒不同耐热性品种在高温胁迫下，花粉、花药发育过程出现异常，花粉生活力、体外萌发率下降，花粉管生长延迟，正在生长的花粉管伸长停滞。这些影响感热性品种比耐热性品种表现更为明显。在雌性系统中未见明显影响。

振动胁迫对杨梅果实采后衰老生理的影响

振动胁迫促进杨梅果实的衰老，表现为促进膜诱性的增加和ＳＯＤ活性与精胺含量的下降。但在振动胁迫后的贮藏初期，果实多源精胺的合成明显增加，而乙烯产生量明显降低，这可能是杨梅果实抗振动胁迫的一种应激机制。而在振动胁迫后的贮藏后期，果实的精胺含量降低，腐胺积累较多，乙烯产生量较高，表明振动胁迫最终促进果实的全面衰老。     

几种中国野生菊的染色体组分析及亲缘关系初步研究

通过对不同倍性的几种中国野生菊之间杂种F1减数分裂期染色体的配对分析,对它们的亲缘关系和演化过程进行了研究。观察到甘菊(Dendranthema lavandulifolium)和菊花脑(D.nankingense)是两个亲缘关系较近、但已发生了某种程度分化的二倍体;南京野菊(D.indicum)和尖叶野菊(D.indicum var.acutum)是含有相同染色体组的异源四倍体,毛华菊(D.sestitum)为异源六倍体,它们在减数分裂中期Ⅰ,染色体均能较好地配成二价体构型。尖叶野菊(4x)与菊花脑(2x)、南京野菊(4x)与毛华菊(6x)的F1,染色体配对构型分别接近于9Ⅰ 9Ⅱ和9Ⅰ 18Ⅱ,表明菊花脑或其近缘种是尖叶野菊染色体组之一的供体,南京野菊或其近缘种是毛华菊两个染色体组的供体。本文还对这几种菊属植物的演化过程进行了讨论。
