Applications of Laparoscopic Techniques in Wildlife 腹腔镜技术在野生动物中的应用

open access: yesWildlife Letters, Volume 3, Issue 3, Page 124-137, September 2025.
In wildlife conservation, we have compiled the applications of laparoscopy, summarized into four areas. First, laparoscopy provides a reliable protocol for sex identification in wild species lacking apparent sexual dimorphism. Second, reproductive management with the involvement of laparoscopy is instrumental in maintaining and restoring species ...

笼养绿孔雀繁殖期行为观察

open access: yes野生动物学报, 2007
采用扫描取样法对秦皇岛野生动物园40只笼养绿孔雀繁殖期的行为进行了为期58d,325h的观察,结果显示繁殖期各行为所占的比例分别为休息31.31%、取食22.03%、理羽16.37%、游走15.93%、警戒9.79%和繁殖4.59%。方差分析和μ检验表明:天气状况对笼养绿孔雀的休息、取食、理羽和游走行为的时间分配的影响明显,但对繁殖和警戒行为影响不大。

Ecological safety assessment of egrets in Xiamen National Nature Reserve [PDF]

open access: yes, 2006
[摘要]:白鹭的生态安全是指白鹭所处的生态系统能够维持白鹭种群持续生存的需求和条件, 其中关键是白鹭生境的安全。白鹭 生境安全从根本上取决于生境的适宜性和人为对生境的干扰程度, 又可以理解为生境受到人类干扰后所能保持的生态适宜性。 分别选择白鹭在厦门的2 个主要繁殖栖息生境 大屿岛和鸡屿岛和10 个代表性觅食生境为研究对象, 对白鹭生境的生态适 宜性和人为干扰程度进行分别评价。其中, 生境适宜性评价采用指标体系法, 通过赋值、计算进行评价; 人为干扰程度评价主要 依靠地理信息系统分析方法 ...

灰雁繁殖期的行为日节律及时间分配

open access: yes野生动物学报, 2011
2011年4~6月,采用瞬时扫描法对徐州睢宁金桥禽业发展有限公司2对繁殖良好的灰雁的繁殖行为时间分配和活动节律进行研究,采用非参数检验的Kruskal-Wallis H法分析不同性别灰雁繁殖前中后期行为的性别差异,以及相同性别的灰雁在繁殖的不同时期的行为差异。结果显示:灰雁在采食、理羽、静立、趴卧、孵化等行为上存在着明显的节律性。取食行为多发生在上午和下午的中间时段,孵化多在早晨和傍晚,而中午的大部分时间处于休息状态。孵化期内雌雄个体的行为差异很大,灰雁繁殖时期各种行为所占的比例不仅存在着一定的性别差异,

The Influencing Factors and Harmonious Ways between Jamily Determination on Child-Bearing and Population Demand of Society [PDF]

open access: yes, 2008
生育决策关系到人口的布局,关系到民族和国家的发展,因此,社会学、社会心理学和经济学各个学科都对生育决策进行了研究。社会学派对生育决策的研究是主流的,但贝克尔将经济学方法引入了家庭和生育决策领域,社会心理学也将心理学理论和方法应用于生育决策的分析,这都拓宽了研究生育决策的视角。纵使诸子百家各持已见,笔者一览全局,认为生育决策是个多元因素影响的过程,不能片面运用单一学科方法和理论进行分析。因此,本文以资本观为分析工具,借用社会-心理-经济分析方法,分别从社会学、社会心理学和经济学多学科角度 ...

人工饲养白枕鹤繁殖期行为观察

open access: yes野生动物学报, 2007
本研究对笼养白枕鹤行为进行观察记录和分析,结果表明笼养白枕鹤繁殖期行为日活动节律依次为休息(32.15%)、取食(30.02%)、理羽(12.92%)、警戒(12.14%)、游走(8.86%)、繁殖(3.90%),另外,繁殖期的不同时期、不同性别其行为时间分配都存在一定差异。人为干扰,邻近笼舍内东方白鹳的干扰,以及外界噪音的干扰对笼养白枕鹤繁殖期行为影响十分显著。同时气候条件以及温度变化对笼养白枕鹤总体行为亦存在一定影响。
