半散养东北虎繁殖期PAE编码行为谱的构建 总被引:2,自引:0,他引:2
2006—2007年,采用全事件记录法、目标动物取样法和行为取样法对泰山东北虎园半散养东北虎繁殖期的各种行为进行了观察。基于以"姿势-动作-环境"(posture-act-environment,PAE)为轴心,以行为生态功能为依据的PAE编码系统,对半散养东北虎的行为进行分类和系统编码并构建PAE行为谱。研究结果区分和定义了14种姿势、47种动作和98种行为型;并将所区分、命名和编码的所有行为型归类于摄食、排遗、调温、发情、交配、分娩、冲突、育幼、通讯、聚群、休息、运动和杂类等13类;由此构建了基于PAE编码系统的半散养东北虎首个繁殖期行为谱。 相似文献

麋鹿行为谱及PAE编码系统 总被引:49,自引:10,他引:39
以麋鹿为实例,通过辨识行为的基本单元,区别了“姿势”、“动作”和“环境”,分解了动物行为的层次,然后根据行为的适应和社群机能归类,建立了以“姿势—动作—环境”为轴心的,以生态功能为分类依据的动物行为分类编码系统(PAE编码分类系统)。PAE编码分类系统以集合论为基础,明确了动物行为的三要素:姿势、动作和生态环境之间的关系,避免了笼统地将动物的姿势、动作和行为混为一谈的做法,区分了动物行为的组成要素和结构层次。行为要素编码方法为动物行为学研究提供了一个新的生长点。在继承前人工作的基础上,记录了有关麋鹿的姿势、动作和行为达200多种,还区别了各种行为在雄性、雌性和幼体之间的相对发生频次以及发生季节。 相似文献

基于PAE编码系统的半放养阿拉伯狒狒的行为多样性 总被引:1,自引:0,他引:1
《生物多样性》2017,(9)
动物行为多样性作为生物多样性的重要组成部分,与珍稀动物的迁地保护以及行为管理密切相关。2015年12月至2016年8月,我们在广州长隆野生动物世界园区内的狒狒岛,利用焦点取样法和瞬时扫描取样法,观察并记录了半放养条件下阿拉伯狒狒(Papio hamadryas)行为的发生过程、内容和环境。基于以"姿势–动作–环境"(posture-act-environment,PAE)为轴心、以行为生态功能为依据的PAE编码系统,对该环境下阿拉伯狒狒的行为进行分类和系统编码,构建并利用PAE行为谱表征其行为多样性。结果如下:(1)研究中分辨并记录到阿拉伯狒狒的18种姿势,120种动作,208种行为;(2)记录到的行为可分别归入摄食、排遗、调温、配对、交配、育幼、亲密、高序位、威胁、攻击、屈服、通讯、聚群、休息、运动、玩耍、讨食和杂类18个类别中;(3)编制基于PAE编码系统的人工饲养阿拉伯狒狒行为谱,描述了各种行为的相对发生频次与性别、年龄的关系;(4)在前人工作的基础上为非人灵长类PAE行为编码系统丰富了两类行为(玩耍行为和讨食行为),描述了半放养环境下阿拉伯狒狒这两类行为的特点,并探讨了其生态功能和适应意义;(5)基于PAE行为谱求得阿拉伯狒狒各年龄–性别组的行为多样性指数。本研究发现,阿拉伯狒狒各年龄–性别组的行为多样性在总体层面上很接近,在细分的行为层面上则有着渐进明显的差别。这表明,利用PAE行为编码分类系统对动物的行为进行归类细分以及编码标准化,对于行为多样性的研究是有帮助的。 相似文献

黔金丝猴的行为谱及PAE编码系统 总被引:2,自引:0,他引:2
2009年10月~2014年4月,在贵州梵净山国家级自然保护区和北京动物园,采用焦点动物取样法和随意取样法,观察记录了野外和圈养黔金丝猴Rhinopithecus brelichi行为发生的过程及环境特征。按照以"姿势-动作-环境"(posture-act-environment,PAE)为轴心,以行为的生态功能为依据的PAE编码系统,对黔金丝猴的行为进行分类和系统编码并构建PAE行为谱。分辨并记录了黔金丝猴的16种姿势,107种动作及163种行为,将记录到的行为分别划归于摄食、排遗、调温、交配、分娩、育幼、亲密、作威、冲突、通讯、聚群、休息、运动和杂类等14个类别中;区别了各种行为在雄性、雌性、亚成体、幼猴和婴猴之间的相对发生频次以及发生季节。与川金丝猴R.roxellana和滇金丝猴R.bieti相比,黔金丝猴在个体行为和社会行为方面均有所不同,这可能与三者生活环境差异有关。 相似文献

利用红外相机建立野生水鹿行为谱及PAE编码系统 总被引:1,自引:0,他引:1
动物行为谱是动物行为学研究的基础。2015年1月至2016年6月,在四川卧龙自然保护区,利用PAE编码分类系统并结合红外相机所获得的照片和视频数据开展水鹿(Rusa unicolor)行为谱的研究,建立了野生水鹿行为谱及其PAE编码系统。本研究共分辨并记录了野生水鹿的7种姿势,63种动作和74种行为,基本涵盖了水鹿的主要行为,并区别了各种行为在成年雄性、成年雌性和亚成体之间的相对发生频次,分析水鹿的具体行为与环境之间的关联。通过建立野生水鹿的行为谱,能为更深入地开展水鹿行为生态学研究提供基础信息,也为水鹿的保护与管理提供依据。该研究可以推广到其他不易直接观测的野生动物的行为学研究中。 相似文献

正Dear Editor,In December 2019, a novel human coronavirus caused an epidemic of severe pneumonia(Coronavirus Disease 2019,COVID-19) in Wuhan, Hubei, China(Wu et al. 2020; Zhu et al. 2020). So far, this virus has spread to all areas of China and even to other countries. The epidemic has caused 67,102 confirmed infections with 1526 fatal cases 相似文献

Curcumin is the yellow pigment of turmeric that interacts irreversibly forming an adduct with thioredoxin reductase (TrxR), an enzyme
responsible for redox control of cell and defence against oxidative stress. Docking at both the active sites of TrxR was performed to compare
the potency of three naturally occurring curcuminoids, namely curcumin, demethoxy curcumin and bis-demethoxy curcumin. Results show
that active sites of TrxR occur at the junction of E and F chains. Volume and area of both cavities is predicted. It has been concluded by
distance mapping of the most active conformations that Se atom of catalytic residue SeCYS498, is at a distance of 3.56 from C13 of
demethoxy curcumin at the E chain active site, whereas C13 carbon atom forms adduct with Se atom of SeCys 498. We report that at least
one methoxy group in curcuminoids is necessary for interation with catalytic residues of thioredoxin. Pharmacophore of both active sites of
the TrxR receptor for curcumin and demethoxy curcumin molecules has been drawn and proposed for design and synthesis of most probable
potent antiproliferative synthetic drugs. 相似文献

The young pistils in the melanthioid tribes, Hewardieae, Petrosavieae and Tricyrteae, are uniformly tricarpellate and syncarpous. They lack raphide idioblasts. All are multiovulate, with bitegmic ovules. The Petrosavieae are marked by the presence of septal glands and incomplete syncarpy. Tepals and stamens adhere to the ovary in the Hewardieae and the Petrosavieae but not in the Tricyrteae. Two vascular bundles occur in the stamens of the Hewartlieae and Tricyrtis latifolia. Ventral bundles in the upper part of the ovary of the Hewardieae are continuous with compound septal bundles and placental bundles in the lower part. Putative ventral bundles occur in the alternate position in the Tricyrteae and putative placental bundles in the opposite. position in the Petrosavieae. The dichtomously branched stigma in each carpel of the Tricyrteae is supplied by a bifurcated dorsal bundle. 相似文献

Rasmussen’s encephalitis (RE) is a rare pediatric neurological disorder, and the exact etiology is not clear. Viral infection may be involved in the pathogenesis of RE, but conflicting results have reported. In this study, we evaluated the expression of both Epstein-Barr virus (EBV) and human herpes virus (HHV) 6 antigens in brain sections from 30 patients with RE and 16 control individuals by immunohistochemistry. In the RE group, EBV and HHV6 antigens were detected in 56.7% (17/30) and 50% (15/30) of individuals, respectively. In contrast, no detectable EBV and HHV6 antigen expression was found in brain tissues of the control group. The co-expression of EBV and HHV6 was detected in 20.0% (6/30) of individuals. In particular, a 4-year-old boy had a typical clinical course, including a medical history of viral encephalitis, intractable epilepsy, and hemispheric atrophy. The co-expression of EBV and HHV6 was detected in neurons and astrocytes in the brain tissue, accompanied by a high frequency of CD8+ T cells. Our results suggest that EBV and HHV6 infection and the activation of CD8+ T cells are involved in the pathogenesis of RE. 相似文献

正Dear Editor,Chikungunya virus (CHIKV), an arbovirus in the family of Togaviridae, genus Alphavirus, is transmitted by the A.aegyptii or A. albopictus mosquito, and causes disease in humans characterized by fever, rash, and arthralgia (Silva and Dermody 2017; Suhrbier 2019). It was first reported in 1953 in Tanzania, and caused only a few outbreaks and sporadic cases in Africa and Asia in last century. However, in the epidemic in 2004, CHIKV acquired mutations that conferred enhanced transmission by the A. albopictus mosquito(Schuffenecker et al. 2006). Since then, it has successively caused outbreaks in Africa, the Indian Ocean, South East Asia, the South America, and Europe (Zeller et al. 2016). 相似文献

In conclusion, the novel visual RT-LAMP assay is a simple, rapid, and sensitive approach for detection of SARS-CoV-2, and it is ready for application in primary care and community hospitals or health care centers, and even patients' own houses in response to the current SARS-CoV-2 epidemic because the assay does not require sophisticated equipment and skilled personnel. Furthermore, it is also ready to be used in fields for screening samples from wild animals and environments to facilitate the identification of potential intermediate hosts that mediate the cross-species transmission of SARS-CoV-2 from bats to humans. 相似文献
