野生动物学报, 2020 人类活动直接或间接地威胁着野生动物的生存，导致许多物种种群数量急剧下降。为保护物种多样性，十分有必要加强野生动物保护教育，调整公众对待野生动物的态度和方式。世界上一些国家关于物种多样性保护教育的法律法规包含在环境教育法中，少数国家制定了专门针对野生动物保护教育的法律。世界野生动物保护教育实践中的成功经验主要有：重视学校的保护教育以及师资的培养；充分发挥非正规教育的力量；利用野生动物保护教育基地开展体验式教育等。世界保护教育相关法律法规及实践经验对加强我国野生动物保护教育的启示有 ...

野生动物学报, 2011 为了解散放情况下盘羊的昼间活动节律、时间分配规律及游人活动的影响,2009年5～6月,在新疆天山野生动物园用直接观察法对909头盘羊的昼间活动节律进行了观察。经过数据统计分析,结果表明:散放情况下盘羊夏季昼间活动规律性较强,从8:00～13:00活动频率较高,之后活动频率逐渐降低,在14:00～15:00降至最低值20%,后逐渐回升,至18:00活动频率达98%。在8:00～10:00和17:00～18:00采食频率较高;11:00～12:00警戒频率较高。昼间各类行为所占的时间比例从大至小为:采食41%

Zhejiang Daxue xuebao. Lixue ban, 2002 采用Percoll密度梯度离心等技术,对处于两种不同活性状态的草鱼头肾和腹腔巨噬细胞(Macrophage, Mϕ)进行了分离纯化,并对两者的生理生化代谢作了比较分析.证实活化Mϕ的体积增大, , H2O2,ACP活性和RNA、蛋白质含量显著升高,吞噬杀菌力明显增强,5′ND活性显著下降,这些变化规律与高等脊椎动物Mϕ相一致,说明鱼类和高等脊椎动物Mϕ存在相同的活化机制., H2O2, ACP, RNA,蛋白质和5′ND活性和含量以及吞噬杀菌力均可作为反映鱼类Mϕ活性水平的生理生化指标.
