Dietary selection of ex-situ population in Chinese Egret [PDF]
2008年至2009年在厦门大屿岛白鹭自然保护区建立了黄嘴白鹭(Egrettaeulophotes)异地种群,对异地种群进行了行为时间分配的研究。在对野生黄嘴白鹭食性进行初步研究的基础上,对异地圈养个体进行了食物选择性实验,并对食物进行了营养成分分析。目的在于了解了异地饲养条件下黄嘴白鹭的取食规律,并根据最佳摄食理论探讨其取食策略。 2008年和2009年两年共从野外采集69只黄嘴白鹭幼鸟,在厦门大屿岛白鹭自然保护区进行饲养,记录种群的存活情况,摸索相关饲养方法。其三月龄的存活率达到60%以上 ...

We profiled nutritional and physiological markers in captive sifakas, endangered primates from Madagascar, managed in expansive, non‐native forest enclosures. Variation in many markers reflects freely foraged diets and the energy required to maintain homeostasis under more naturalistic conditions.

After the great Chinese poet Qu Yuan (屈原) was exiled to Xupu (溆浦) county in Hu' nan province, he described the forest there as follows: “mysterious is the deep forest, the place where Yuán yòu dwell (深林杳以冥冥兮,乃猿狖之所居).” What is the referent of the name Yuán yòu in this sentence?

ABSTRACT This paper replicates and extends prior work that demonstrated the general importance of friendships for maintaining well‐being, with a focus on unpartnered/single individuals. Using data from two quota samples of U.S. adults (Nsingle2022 = 552, Nsingle2023 = 391), we systematically examined how 10 theoretically derived characteristics of ...

Commentary to: An integrated historical study on human–tiger interactions in China 中国境内人虎互动的综合历史研究
Abstract The tiger holds a revered position in Chinese culture, symbolizing power and strength, yet its coexistence with human populations has often been marked by tension and conflict. Understanding the historical dynamics of human‐tiger relations is essential for comprehending the current state of tiger populations and shaping future coexistence with

应用种群管理软件SPARKS 1.6及PMX对中国黑叶猴圈养种群的现状进行了统计分析。截至2012年12月31日,黑叶猴谱系记录了574只个体,目前种群存活个体数量为318只,分布在34家动物园或机构中。圈养种群野外捕获个体主要来源于20世纪70~90年代,目前保持稳定状态。圈养出生个体数则一直保持上升状态,是维持黑叶猴圈养种群增长的主要来源,2012年圈养出生数量占种群总数的87.4%。种群周期增长率λ=1.042,性比M:F=1:1.04,目前种群中能够繁殖的个体共110只(♂48只,♀62只 ...

Molecular markers are widely used in conservation genetics of wildlife. A total of 15 novel microsatellite loci with high polymorphism of Blue‐crowned laughingthrush were developed in this study. The genetic diversity level of wild individuals was higher than two captive populations including Ocean Park Hong Kong and Nanchang Zoo. The genetic diversity

为探究圈养梅花鹿(Cervus nippon)肠道菌群的结构、多样性以及肠道菌群组成的性别差异,利用Illumina MiSeq高通量测序平台对10只圈养健康梅花鹿粪便中的细菌16S rRNA V3—V4区扩增子进行PCR扩增,采用生物信息学手段以性别作为分组因素,分析雄、雌圈养梅花鹿肠道菌群的结构、多样性和差异物种。结果显示:在门水平上,圈养梅花鹿肠道菌群的优势菌门为厚壁菌门(Firmicutes;雄性61.69%,雌性58.23%)和拟杆菌门(Bacteroidetes;雄性27.40%,雌性31 ...
