Coastal reclamation impacts on carbon storage in China’s coastal wetland [PDF]
, 2017 滨海湿地具有较高的初级生产力和较缓慢的有机质降解速率，是缓解全球变暖的有效碳汇，得到全球学术界的广泛关注。近年来由于人口增长和沿海城市的快速发展，海岸带地区围填海活动呈加剧趋势，导致滨海湿地的急剧退化。开展围填海活动对滨海湿地碳储量造成影响的研究，对我国海岸带围填海活动的优化管理、制定滨海湿地保护行动计划以及减缓气候变化的战略决策具有非常重要的学术价值和现实意义。 本论文以全国围填海区内的滨海湿地作为研究对象，基于全国围填海土地利用分类数据、滨海湿地和沿海自然保护区空间分布数据以及文献检索碳密度数据 ...

Engaging youth in biodiversity education through visual narrative
Conservation Biology, Volume 38, Issue 6, December 2024.Abstract Engaging youth in early and sustained conservation education has important implications for promoting positive attitudes and behaviors in those who will become the future of conservation and management. Toward this goal, visual narratives (comic books, graphic novels) are an increasingly popular method used by conservation scientists to ...

, 2009 通过土壤盆栽研究了不同浓度镉(CCdd，0、2.5、50 mg kg -1)、锌(ZnZn，0、100、500 mg kg -1)胁迫下红树植物秋茄的 幼苗体内可溶性蛋白、可溶性糖、脯氨酸、有机酸含量的变化. 结果表明，Cd 、Zn 单一处理下，秋茄体内渗透调节物质 含量随重金属浓度升高而增加；Cd 、Zn 复合处理对秋茄体内可溶性蛋白质含量的复合效应主要表现为协同作用：Cd 的加入减弱Zn 对秋茄体内可溶性糖含量的刺激作用，低Cd 浓度处理下Zn 的加入导致可溶性糖含量增加，而高Cd 浓度 ...

Wildlife Letters, Volume 2, Issue 3, Page 149-164, September 2024.Time‐local convex hull indicates smaller home range size for the African savannah elephants than MCP, indicating that elephants are likely exploiting certain regions more intensively rather than traveling extensively. During the transitional season, the home range size grows.

Gradient distributions of nitrogen and organic carbon in the soils from inland to tidal flat in the Yellow River Delta [PDF]
, 2014 黄河三角洲是我国典型的通过黄河冲积泥沙填海造陆形成的近代沉积区。区域受到黄河冲积、沉积等自然过程和农业耕种熟化等人类活动的双重影响。本研究通过在黄河三角洲地区内陆到河口海湾不同距离采集典型土壤类型剖面发生层样品，探讨土壤有机碳、总氮等生源要素的空间分布规律，为阐明我国典型海岸带地区陆源碳、氮的输送及循环特征提供基础依据。研究结果表明，黄河三角洲内陆与河口地区呈现出完全不同的土壤碳、氮分布规律。表层土壤碳、氮含量在黄河沿岸及三角洲南部均表现出由陆向海逐级递减的空间分布特征 ...

Influence of microclimate and forest management on bat species faced with global change
Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Climate refugia, areas where climate is expected to remain relatively stable, can offer a near‐term safe haven for species sensitive to warming temperatures and drought. Understanding the influence of temperature, moisture, and disturbance on sensitive species is critical during this time of rapid climate change.

野生动物学报, 1999 今年江河横溢,早在意中,名曰天灾,实为人祸.道理很简单,森林被砍了,湿地被占了,长江和诸多河流忍无可忍,不得不以暴怒的姿态发话了,这才使得许多人猛省过来.我们应该借助于大自然的现身说法,因势利导,努力认识湿地,宣传湿地,保护湿地.今年的主题是“保护湿地”组织大学生绿色营今年是第三届了.1996年为保护滇金丝猴奔赴滇西北;1997年为保护原始森林奔赴藏东南 ...
