Effect of root exudate on behavirors of polycyclic aromatic hydrocarbons (PAHs) in mangrove sediments [PDF]
, 2016 红树林是生长在热带、亚热带海岸潮间带的木本植物群落，对维护河口、海滨生态平衡和保护环境等方面具有重要意义。近年来，大量污染物被排放到红树林湿地生态系统中，其中以多环芳烃（Polycyclicaromatichydrocarbons，PAHs）为代表的有机污染物最为明显。由于PAHs具有较强的致癌、致畸、致突变作用，使其极易在沉积物中被吸附固定，研究根系分泌物对沉积物中PAHs的活化作用，植物修复PAHs的根际响应机制及其在根际微环境中的降解机理，将为深入探讨PAHs在根际沉积物中的生物有效性 ...

The underappreciated roles of fog and dew on vegetation and biocrusts
New Phytologist, EarlyView.Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

A Case Study on the Evolution Mechanism of Ambidextrous Competence of Business Incubator among Entrepreneurial Incubation Ecosystem [PDF]
, 2016 科技企业孵化机构在扶持区域创业创新活动中的重要性不言而喻。在中国经济转型的大背景下，创业活动之繁荣前所未有，原先服务单一的孵化机构已无法适应创业企业多样化的需求，正在积极向多方资源整合者的角色转变。在实践中，转型成功的孵化机构身上普遍具有同时开展利用式创新和探索式创新的双元能力。因此探索孵化机构发挥双元能力的过程，对促进我国孵化行业发展以及营造区域良好创业孵化生态至关重要。然而学界尚缺乏对孵化机构的双元能力的动态研究，导致科技孵化机构的孵化实践缺乏理论指导而陷入盲目摸索的尴尬状况 ...
