Patterns and Internal Stability of Carbon, Nitrogen, and Phosphorus in Soils and Soil Microbial Biomass in Terrestrial Ecosystems in China: A Data Synthesis
spatial pattern C:N:P vegetation types nutrient limitation homeostasis
2023/12/11
Inspired by the strict constraint ratio (relatively low variability) between carbon (C), nitrogen (N), and phosphorus (P) in global soils and soil microbial biomass, our study explores the biogeograph...
The Soil Aggregates and Associated Organic Carbon across the Greater Khingan Mountains: Spatial Patterns and Impacting Factors
Greater Khingan Mountains forest soils soil aggregates soil organic carbon spatial variation
2023/12/1
1) Background: The preservation of soil organic carbon (SOC) by soil aggregates (SA) is a key mechanism for the stability of the soil carbon (C) pool. (2) Methods: Soil samples were collected at a 0–2...

日前，2018级博士研究生夏宇轩在国际学术期刊《分形》发表题为《一种基于多孔介质孔径分布的分形维数新计算方法》的论文，入选Mathematics学科领域高被引论文。在该论文中，夏宇轩提出了一种基于分形毛细管假设的计算多孔介质孔隙空间和迂曲度分形维数的新方法。
在这项研究中，我们对七个优良棉花品种的PAV模式进行了综合分析，发现大部分PAV小于20kb,小于40kb的PAV总共有1.27Gb，占到整个基因组的50.7%，大于40kb的PAV共有15430个，共有1.23Gb，占到整个基因组的49.3%。基因结构分析发现大部分缺失型PAV不在内含子区域或者外显子区域，说明这些PAV可能不对基因功能起直接作用。多倍性PAV主要定位在内含子区域，并且紧邻外显子...
