Advancing conservation breeding programs for marine invertebrates
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

四川冬水田的发展史大致可分为清代的兴起与扩展,民国的继承与发展,新中国的改造与缩减三大阶段。水稻种植规模的大小、劳动生产率的高低、水利设施的多少均是影响冬水田发展的因素之一。以往提高农业产出的是改造冬水田的动因;现今提倡恢复冬水田又是出于其水利、生态湿地价值的考虑。冬水田作为一项大规模的水利工程,其之于四川农业 ...

采用硅氧烷修复液修复交联聚乙烯电缆老化试样中的水树,进而分析修复效果及机理。将介质损耗因数为4%~6%,绝缘电阻7 500~10 000 MΩ的短电缆在7.5 kV 450 Hz交流电压下老化至介质损耗因数达到20%左右,绝缘电阻3 500~5 000 MΩ。然后用压力注入式修复装置把修复液注入缆芯对水树缺陷进行修复。以介质损耗因数、绝缘电阻和击穿电压为指标对修复效果进行评判;通过显微镜切片观察修复前后水树微观形态;通过仿真修复前后水树附近电场分布来分析和验证水树的修复机理。实验结果证明 ...

Contribution of Different Processes in Wetland Soil N_2O Production in Different Restoration Phases of the Yellow River Estuary, China [PDF]
采用时空替代法,选择黄河口生态恢复前后未恢复区(R_0)、2007年恢复区(R_(2007))和2002年恢复区(R_(2002))的芦苇湿地为研究对象,分析了生态恢复工程对湿地土壤N_2O产生不同过程与贡献的影响. 结果表明,尽管不同恢复阶段湿地土壤N_2O总产生量差异明显,但总体均表现为N_2O释放. 恢复区湿地土壤的N_2O产生量大于未恢复区.

土壤水热因子是影响作物生长发育的重要因子,尤其是在黄土高原自然植被恢复过程中。通过对黄土高原不同自然植被恢复阶段的土壤水分和温度的长期监测,研究植被恢复过程中土壤温度和水分的动态变化及其相关性。结果表明:8-10月草地群落的土壤温度显著高于其他群落,11月辽东栎林群落的土壤温度显著高于其他群落,随着植被恢复,土壤温度变化的范围和峰值均有不同程度的减小,土壤水分有所减少,但并不影响土壤水分随时间变化的总体趋势,不同植被恢复阶段土壤温度和水分呈显著负相关,植被恢复过程中土壤水分有一定的时间稳定性 ...
