Marine flavobacterium Gramella flava JLT2011 utilization polysaccharide of phytoplankton and characterization of new species of Pelagibaca bacterium [PDF]
, 2015 海洋浮游植物是海洋食物网的初级生产者，是海洋有机质重要分泌者。海洋浮游植物光合作用产生的有机质,通过海洋细菌分泌的一系列胞外酶等将颗粒有机质POM（ParticleOrganicMatter,POM）进一步代谢为生物可利用的溶解有机质（BioavailableDissolvedOrganicMatter,BDOM）。在这一个过程中噬纤维菌-黄杆菌-拟杆菌(Cytophaga-Flavobacterium-Bacteroides,CFB)菌群起着重大的作用。这类细菌形态多样，一般具有较强的运动性和粘附性 ...

Integrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

The Key Process of Colonization and Spread of Sonneratia apetala introduced in the Local Mangrove Wetland [PDF]
, 2016 无瓣海桑(Sonneratiaapetala)于20世纪80年代引入中国后，由于其具备速生性、抗逆性等生理特点，被广泛种植于中国华南沿海地区，随着种植面积的增大，人们对于无瓣海桑的入侵潜力产生了担忧。本研究选择雷州湾北家村红树林保护区为主要研究区域，通过野外调查、野外种植、室内对照的方式研究了无瓣海桑的果实凋落、果实漂浮、土壤种子库分布、林窗内无瓣海桑的定植、光胁迫下的生理响应，为无瓣海桑防治积累了科学的理论依据。本研究结果如下： 无瓣海桑的果实一年内有两次成熟期，秋季为无瓣海桑成熟的主要季节 ...

Shuitu Baochi Xuebao, 2005 采用第二次土壤普查资料,研究了安徽省不同土地类型表层土壤的有机碳密度和碳库的特点。结果表明,安徽省平均有机碳密度为(31.64±16.39)tC/hm2,林地土壤表层有机碳密度高于全省表层土壤平均有机碳密度,旱作土壤表层有机碳密度则低于全省平均值。有机碳密度的大小顺序为:林地>水稻土耕层>旱地。安徽省表层土壤有机碳储量分布也表现为:林地>水稻土>旱地。表层土壤有机碳总量达0.28 Pg,其中林地占50%,水稻土占23%,而旱地只占18%。因此,人为利用特点是区域土壤碳库和碳密度的主要影响因素。分析表明 ...

World Water Policy, Volume 10, Issue 4, Page 1170-1186, November 2024.Abstract Sustainable land management (SLM) practices is a key to reducing rates of land degradation and has proven to ensure water security by increasing soil moisture availability, decreasing surface runoff, decreasing soil erosion, increasing infiltration, and decreasing flood discharge. Land degradation is adversely affecting over 75% of the Earth's
