Indices of Biological Integrity (IBIs) are being increasingly used as useful and direct tools for assessing general health of aquatic ecosystems. Although such ecosystems in Iraq, especially the southern marshes, underwent severe alterations during the last two decades, including extensive desiccation in the 1990s, such tools are largely lacking. Phytoplankton Index of Biological Integrity (P-IBI) was developed from data collected seasonally from 2005 up to 2007 in different sites of the southern marshes of Iraq to evaluate the trend of these ecosystems based on phytoplankton data. Ten metrics were selected for measuring P-IBI for the first time in Iraq as a proposed project from Nature Iraq and Twin Rivers Institute, American University of Iraq-Sulaimani. Although generally fluctuated both spatially and temporally, mean P-IBI scores showed better conditions in Al Hawizeh marsh (Good) as compared to the Central and West & East Al Hammar marshes (Fair to Good). However, the results generally indicated evidence of improvement at the Central and West & East Al Hammar marshes, whereas no recovery of the status of water was evident throughout the data obtained at Al Hawizeh marsh. Values were generally higher in winter. These observations clearly reflect the relative stability of the Hawizeh marsh ecosystem which was not subject to the desiccation process in the 1990s, while the severely dried systems of the Central and Hammar marshes are showing positive responses to the restoration efforts that were started after 2003. Among the ten metrics comprising the index, relative abundance of diatoms had the most prominent effect on the P-IBI value in the three marshes. Metrics such as chlorophyll- a concentration and relative abundance of Cyanophyta and Chlorophyta also played a significant role in determining the index value. Continuous monitoring based on the selection of the most suitable metrics is recommended.

本研究以玉米蚜为研究对象,在云南省昭通地区通过田间调查和相关数据分析,研究了玉米蚜田间种群动态,评价了27个不同品种玉米的抗蚜性,探索了更为简便的玉米抗蚜性评价方法。结果表明:玉米蚜在田间的发生有两个高峰期,分别是抽雄散粉期和蜡熟期;采用玉米整个生育期蚜量比值法比较不同品种玉米的抗性,发现高抗品种有6个、抗性品种有6个、中抗品种有6个、感虫品种有4个、高感品种有5个,玉米蚜的种群数量在不同品种玉米间存在显著差异;采用玉米蚜暴发时期到玉米完熟期的蚜量比值来评价玉米抗蚜性可行。

2005年大选之后的经历给伊拉克国内各政治力量留下了深刻教训,他们意识到国家的安全和稳定需要一个有什叶派、逊尼派以及库尔德人代表参加的联合政府。2010年大选产生了一个联合政府,该政府将有机会实现国家统一,并向邻国传递积极的信号,即伊拉克不会对它们产生威胁,同时新政府也将面临巨大挑战。选举产生的政府将承担起领导国家走向主权独立的历史责任,并努力提高伊拉克在该地区的地位和影响力,尤其是在2011年底美军撤出伊拉克之后。2010年12月21日,新内阁获得国民议会投票表决通过,从而开启了多党派联合执政的架构。

目的评价陕西省神木县气象因素与儿童下呼吸道感染住院人数的关系。方法收集2009年1月至2012年12月神木县气象因素（气温、气压、降雨量、光照时间、风速和相对湿度）及≤16岁儿童的住院资料。利用SAS9．3对气象、下呼吸道感染住院人数、总住院人数和下呼吸道感染住院率进行描述性分析。了解各气象因素与下呼吸道感染住院率之间的相关程度，并探讨气象因素与下呼吸道感染住院率之间相关性。结果纳入研究的对象19772例，其中下呼吸道感染住院患者4449例，占22．5％。下呼吸道感染住院率与气温（r=-0．651，P〈0．001）、气压（r=0．560，P〈0．001）、降雨量（r：-0．614，P〈0．001）和相对湿度（r=-0．470，P〈0．001）呈显著相关，而与光照强度、风速无相关性。多重线性回归分析发现，下呼吸道感染住院率随着平均气温和平均湿度的上升而逐渐下降（F=38．30、15．58，P均〈O．001）。结论平均气温和平均湿度是影响神木县儿童下呼吸道感染住院率的主要气象因素。

Rapeseed (Brassica napus),an important oilseed crop,has adapted to diverse climate zones and latitudes by forming three main ecotype groups,namely winter,semiwinter,and spring types. However,genetic variations underlying the divergence of these ecotypes are largely unknown. Here,we report the global pattern of genetic polymorphisms in rapeseed determined by resequencing a worldwide collection of 991 germplasm accessions.A total of 5.56 and 5.53 million singlenucleotide polymorphisms (SNPs)as Well as 1.86 and 1.92 million InDels were identified by mapping reads to the reference genomes of "Darmor-bzh"and "Tapidor,"*** generated a map of allelic drift paths that shows splits and mixtures of the main populations,and revealed an asymmetric evolution of the two subgenomes of *** by calculating the genetic diversity and linkage disequilibrium ***-sweep analysis revealed genetic changes in genes orthologous to those regulating various aspects of plant development and response to stresses.A genome-wide association study identified SNPs in the promoter regions of FLOWERING LOCUS T and FLOWERING LOCUS C orthologs that corresponded to the different rapeseed ecotype groups. Our study provides important insights into the genomic footprints of rapeseed evolution and flowering-time divergence among three ecotype groups,and will facilitate screening of molecular markers for accelerating rapeseed breeding.

Hydro-Pericardium Hepatitis (HPH) is an emerging infectious disease of commercial poultry, caused by different serotypes of Fowl Adeno Virus. The vertical transmission of the virus into the progeny may results in devastating damage, causing huge economic losses to its farmers. In present study, molecular typing is performed on basis of partially conserved hexon gene sequences, using a unique set of primers having common reverse oligo for simultaneous detection of FAdV1, FAdV-4 and FAdV-11. A total of 14 fowl adeno virus strains were isolated from 100 suspected adeno virus liver samples, collected from different districts in Pakistan, between 2018 and 2019. FASTA’s sequence alignment and phylogenetic analysis revealed that out of the 14, one isolate which belonged to group A showed 27% similarity with FAdV-1, while three isolates showed 99%, 95% & 45% similarity to FAdV-4 (Group C). Whereas, ten isolates showed more than 99% similarity to FAdV-11 (Group D). The serotypes FAdV1, FAdV-4 and FAdV-11 are prevailing in the breeder and broilers. These results hold great importance in rapid, reliable and simultaneous detection of the three FAdV serotypes. Therefore, fowl adeno virus vaccine production for commercial poultry shall be according to the prevalent field serotypes.
