| 1 | N_2O emissions from agricultural soils in the North China Plain: the effect of chemical nitrogen fertilizer and organic manure显示文摘An enclosed chamber technique was used to measure N 2O emissions from intensively agricultural soils of the North China Plain during the periods of 1995—1996 and 1997—1998, to reflect distinct components of winter wheat and summer maize growing seasons. The results showed that the continuous application of fertilizer in agricultural soils increased N\-2O emissions by a factor of 24.1—28.1, the calculated annual chemical N fertilizer\|transformed N\-2O\|N emissions was 0.67%. Our results indicated that the application of organic manure also had a significant influence on soil N 2O emissions, which combined with the use of chemical N increased about 20% in a year. It was calculated that there were about 0.11% N of organic manure transformed as N 2O N. Annual mean N 2O emission from our study area of fertilized soils was estimated to be 57.1 μgN 2O/(m 2·h). A weak correlation was also found between N 2O emissions and soil available nitrogen content NH + 4. | DONG Yun\|she 1,2,3 , Dieter Scharffe 2, Manfred Domroes 3, QI Yu chun 1, ZHANG Shen 1 (1.

| 2 | Rapid phenotypic evolution with shallow genomic differentiation during early stages of high elevation adaptation in Eurasian Tree Sparrows显示文摘Known as the‘third polar region’,the Qinghai-Tibet Plateau represents one of the harshest highland environments in the world and yet a number of organisms thrive there.Previous studies of birds,animals and humans have focused on well-differentiated populations in later stages of phenotypic divergence.The adaptive processes during the initial phase of highland adaptation remain poorly understood.We studied a human commensal,the Eurasian Tree Sparrow,which has followed human agriculture to the Qinghai-Tibet Plateau.Despite strong phenotypic differentiation at multiple levels,in particular in muscle-related phenotypes,highland and lowland populations show shallow genomic divergence and the colonization event occurred within the past few thousand years.In a one-month acclimation experiment investigating phenotypic plasticity,we exposed adult lowland tree sparrows to a hypoxic environment and did not observe muscle changes.Through population genetic analyses,we identified a signature of polygenic adaptation,whereby shifts in allele frequencies are spread across multiple loci,many of which are associated with muscle-related processes.Our results reveal a case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution,shedding light on early stages of adaptive evolution to a novel environment. | Yanhua Qu Chunhai Chen Ying Xiong Huishang She Yong E Zhang Yalin Cheng Shane DuBay Dongming Li Per G P Ericson Yan Hao Hongyuan Wang Hongfeng Zhao Gang Song Hailin Zhang Ting Yang Chi Zhang Liping Liang Tianyu Wu Jinyang Zhao Qiang Gao Weiwei Zhai Fumin Lei | 2020 | National Science Review2020，7，1： | 2 |
