11998年印度洋珊瑚死亡事件的生态影响和社会经济影响:是ENSO影响和未来变化的警告吗?显示文摘自大约15O年前开始有气温记录以来,1998年是所记录到的最热的一年,20世纪90年代是最热的十年。另外,1998年也是有记录以来厄尔尼诺现象最严重的一年。这一现象产生的结果是,海洋中许多地方的水温很高,尤其是位于热带的印度洋的水温常常比正常年份高3~5℃。该区域内的大量珊瑚脱色并死亡,可能是由于高的水温以及其它气象、气候因子共同作用所致。斯里兰卡、马尔代夫、印度、肯尼亚、坦桑尼亚和塞舌尔群岛的珊瑚礁中珊瑚的死亡率较高,许多浅海区甚至高达90%。在位于印度洋其它地方和距海面20米以下的珊瑚礁中,珊瑚的死亡率通常为50%。因此,1998年珊瑚的死亡情况是空前严重的。印度洋的珊瑚褪色对沿海社区的二级社会经济影响可能是长期的和严重的。除了鱼资源可能减少和对旅游造成不良影响外,侵蚀可能成为一个严重的问题,尤其是在马尔代夫和塞舌尔群岛。如果目前已经发现的全球温度升高的趋势继续下去,那么1998年印度洋珊瑚礁上发生的情况在未来一些年内极有可能加剧并在其它的热带海洋区出现。印度洋的珊瑚礁可能是反映全球气候变化潜在影响的一个重要信号,我们应当对这一警告引起注意。Clive Wilkinson OlofLindén Herman Cesar Gregor Hodgson Jaston Rubens Alan E.Strong 李岱青 1999人类环境杂志1999,28,2:4
2Anti-porcine circovirus type 2(PCV2) antibody placental barrier leakage from sow to fetus: impact on the diagnosis of intra-uterine PCV2 infection显示文摘Dear Editor,Fetuses develop antibodies when they are infectedwith porcine circovirus type 2(PCV2).At abortion orbirth,both PCV2 and/or anti-PCV2 antibodies can thenbe detected.Finding anti-PCV2 antibodies in aborted fe-tuses or stillborn piglets is generally used as evidence ofan intra-uterine PCV2 infection.However,a recent anal-ysis of fetuses sent in for PCV2 diagnosis and caesare-an-derived,colostrum-deprived pigs revealed thatDipongkor Saha Rubén Del Pozo Sacristán Nicolaas Van Renne Liping Huang Ruben Decaluwe Annelies Michiels Alfonso Lopez Rodriguez Maria José Rodrí-guez Margarita García Durán Ilse Declerk Dominiek Maes Hans J.

4Shoot-level biomass allocation is affected by shoot type in Fagus sylvatica显示文摘Aims The present study aims(i)to examine if recently reported interspecific shoot-level biomass allocational trade-offs,i.e.isometric trade-offs between leaf mass(LM)and stem mass(SM)and between leaf size and leaf number,hold intraspecifically and(ii)to explore whether those scaling relationships are independent of shoot type(i.e.long vs.short shoots).Methods In order to address our questions,we used Fagus sylvatica saplings growing under a broad light range that were sampled in theWestern Carpathians Mountains(Slovakia).Important Findings We found that:(i)intraspecific shoot-level biomass allocational trade-offs differ from those reported interspecifically and that(ii)long and short shoots differ in biomass allocation scaling coefficients.Allometric relationships with slopes statistically smaller than 1.0 or higher than-1.0,were found between SM and LM and between mean leafing intensity and individual leaf mass,respectively,in long shoots.In contrast,isometric scaling was found in short shoots.This suggests that leaf mass in short shoots is unaffected by shoot stem mass,in contrast to long shoots.Short shoots also had a larger fraction of biomass allocated to leaves.Beech shoots,as has been observed in other shoot dimorphic species,are specialized,with short shoots specializing in carbon gain and long shoots in space acquisition.A greater shift in LM than in SM among species during speciation shifting from allometric intraspecific relationships to an isometric interspecific scaling relationship between those traits could explain the discrepancies between the outputs of the present intraspecific study and others similar studies.This study draws attention to the importance of considering shoot types in future studies dealing with allocation rules in species with dimorphic shoots.Benjamín Jarcuska Ruben Milla 2012Journal of Plant Ecology2012,5,4:2
