Sequencing multiple species that share the same ecological niche may be a new frontier for genomic *** such studies should shed light on molecular convergence, genomic-level analyses have been unsuccessful, due mainly to the absence of empirical controls. Woody plant species that colonized the global tropical coasts, collectively referred to as mangroves, are ideal for convergence studies. Here, we sequenced the genomes/transcriptomes of 16 species belonging in three major mangrove clades. To detect convergence in a large phylogeny, a CCS+ model is implemented, extending the more limited CCS method(convergence at conservative sites). Using the empirical control for reference, the CCS+ model reduces the noises drastically, thus permitting the identification of 73 convergent genes with Ptrue(probability of true convergence) > 0.9. Products of the convergent genes tend to be on the plasma membrane associated with salinity tolerance. Importantly, convergence is more often manifested at a higher level than at amino-acid(AA) sites. Relative to >50 plant species, mangroves strongly prefer 4 AAs and avoid 5 others across the genome. AA substitutions between mangrove species strongly reflect these tendencies. In conclusion, the selection of taxa, the number of species and, in particular, the empirical control are all crucial for detecting genome-wide convergence. We believe this large study of mangroves is the first successful attempt at detecting genome-wide site convergence.

Salinity influence on soil microbial respiration rate of wetland in the Yangtze River estuary through changing microbial community

引用

Journal of Environmental Sciences 2014年第12期26卷 2562-2570页

作者： Xue Fei Xi Lei Wang Jia Jun Hu Yu Shu Tang Yu Hu Xiao Hua Fu Ying Sun Yiu Fai Tsang Yan Nan Zhang Jin Hai Chen Key Laboratory of Yangtze River Water Environment Ministry of Education College of Environmental Science and EngineeringTongji University Collaborative Innovation Center for Regional Environmental Quality College of Civil Engineering Tongji University Shanghai Jiuduansha Wetland nature reserve administration Department of Science and Environmental Studies Hong Kong Institute of Education

Estuarine wetland, where freshwater mixes with salt water, comprises different regions（rivers and marine ecosystems） with significantly varying tidal salinities. Two sampling areas, ZXS and JS, were selected to investigate the effect of tidal salinity on soil respiration（SR）. ZXS and JS were located in Zhongxia Shoal and Jiangyanan Shoal of Jiuduansha Wetland respectively, with similar elevation and plant species, but significantly different in salinity. The results showed that with almost identical plant biomass, the SR and soil microbial respiration（SMR） of the tidal wetland with lower salinity（JS） were significantly higher than those of the tidal wetland with higher salinity（ZXS）（p 〈 0.05）. However, unlike SMR and SR, the difference in the soil microbial biomass（SMB） was not significant（p 〉 0.05）with the SMB of ZXS a little higher than that of JS. The higher SMR and SR of JS may be closely connected to the soil microbial community structures and amount of dominant bacteria. Abundant β- and γ-Proteobacteria and Actinobacteria in JS soil, which have strong heterotrophic metabolic capabilities, could be the main reason for higher SMR and SR,whereas a high number of ε-Proteobacteria in ZXS, some of which have carbon fixation ability, could be responsible for relatively lower carbon output. Path analysis indicated that soil salinity had the maximum negative total influencing coefficient with SMR among the various soil physical and chemical factors, suggesting that higher soil salinity, restricting highly heterotrophic bacteria, is the principle reason for lower SMR and SR in the ZXS.

生物多样性与生态系统功能之间的关系已成为森林生态系统研究的核心问题。然而,在具有不同人类干扰历史的亚热带森林群落中,关于环境因子对生物多样性与生态系统功能关系影响的研究仍然较少。在本研究中,选择位于中国东部浙江省的34个亚热带森林样地,在考虑样方中的环境因子的基础上,利用线性模型,分析样地中木本植物多样性(物种、功能和谱系多样性)与样方内木本植物生物量或生物量变化量之间的关系。物种多样性和功能多样性,并非谱系多样性,与生物量和生物量的变化量之间存在显着相关性。生物量或生物量变化量与年平均温度和海拔高度之间存在显著的正相关关系。此外,在考虑环境因子和森林群落的演替阶段时,生物量变化量与功能多样性的关系显著强于生物量变化量与谱系多样性或物种多样性之间的关系。这些研究结果表明,生物多样性与生态系统功能之间的关系可能取决于生物多样性指数的选择和环境条件。

Influences of the Weather and Climate on Wintering Migratory Bird in Dongting Lake

引用

Meteorological and Environmental Research 2012年第11期3卷 29-32,64页

作者： HUANG Ju-mei NIU Ling-zhi YAO Yi QIN Hong Dongting Lake Climate Center Yueyang Meteorological Bureau in Hunan Province East Dongting Lake national nature reserve administration in Hunan

[Objective] The research aimed to study influences of the weather and climate on wintering migratory bird in Dongting Lake. [Method] Bird analysis data provided by East Dongting Lake national nature reserve and wintering migratory bird monitoring data in big and small west lakes in recent 5 years were used. By combing water level data and various meteorological factors in Chenglingji, wintering migratory bird in Dongting Lake was analyzed. [Result] Abnormal precipitation led to drought or flood in Dongting Lake, causing significant adverse effect on the birds. Abnormal climate was important reason for that wintering migratory bird greatly reduced, such as high temperature and later going south of the strong cold air. Extreme weather and climate events led that some birds in Dongting Lake significantly reduced. Meteorological element had certain influence to bird survey. We should select a reasonable investigation time based on weather and climate. In Birding Festival, weather had little effect on bird species observation. In the migratory season of bird, we could see many birds in fine cold weather after a strong cold air, which suitable for observing bird. When it was low temperature or less rain in autumn, and was high temperature or more rain and sunshine in early winter, it was suitable for migratory birds wintering in Dongting Lake. Ardea cinerea, Anser fabalis and Anser erythropus were more in sunny days while Phalacrocorax carbo was more in rainy weather. Grus grus was more in heavy wind weather while Recurvirostra avosetta was more in small wind weather. [Conclusion] The research provided scientific basis for studying migratory bird in east Dongting Lake.
