长江江豚感染铜绿假单胞菌肺炎的诊治 [PDF]

open access: yes, 2007
本文记录了一例患急性铜绿假单胞菌肺炎的长江江豚诊断、治疗和预后观察过程。病原学鉴定采用鲜血琼脂平板对该江豚鼻腔拭子,在37℃下进行细菌需氧、厌氧培养和分离,并对所分离的细菌种类进行细菌学鉴定,结合血常规和血生化的检测结果,判定病原为铜绿假单胞菌(Pseudomonasaeruginosa,PA)。依据病原菌的药敏试验结果对患病江豚进行治疗,预后良好。通过对整个过程的资料分析以及预后观察,得到如下提示:1)应做好饲养环境的消毒措施,防止江豚出现获得性PA感染;2)对江豚日常呼吸道和粪便中PA的检测 ...

Taxonomy of Genus Branchiostoma in Xiamen Waters and Continuous Breeding of Two Lancelets in the Laboratory [PDF]

open access: yes, 2007
文昌鱼是现存无脊椎动物中与脊椎动物直接祖先很相似的一个类群,在动物进化史上占据重要的地位,是进化发育生物学和比较基因组学研究领域的重要模式生物。厦门曾经以盛产文昌鱼并形成世界上唯一的文昌鱼渔场而闻名于世,厦门文昌鱼自1932年被鉴定为白氏文昌鱼BranchiostomabelcheriGray以来一直被认为是同一种,直到2005年应用分子生物学技术进行文昌鱼物种鉴定时,才发现其中包含有2个独立物种,即白氏文昌鱼B.belcheri和日本文昌鱼B.japonicum。本研究详细观察了这2种文昌鱼大量标本 ...

Use of consumer insights to inform behavior change interventions aimed at illegal pet turtle trade in China

open access: yesConservation Biology, Volume 38, Issue 5, October 2024.
Abstract Illegal poaching and overexploitation for the international pet trade are among the greatest threats to freshwater turtles in Southeast Asia. Expanding consumer research in China is crucial to filling knowledge gaps about the scale and structure of illegal trade and developing audience‐targeted and relevant interventions that may reduce demand

Effects of captions on viewers’ perceptions of images depicting human−primate interaction

open access: yesConservation Biology, Volume 38, Issue 3, June 2024.
Abstract Promoting human contact with wildlife can be harmful to animal conservation and welfare by exposing animals to unsafe situations and driving demand for wildlife tourism and exotic pets. Conservationists and researchers justifiably use social media to raise awareness, but professionals posting pictures of themselves with animals can have ...

Dietary selection of ex-situ population in Chinese Egret [PDF]

open access: yes, 2010
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 ...

Egretta eulophotes’ Cluster Breeding Impact on Heavy Metals in Soil of Nest Area and The Study of Their Molt [PDF]

open access: yes, 2012
本研究采用电感耦合等离子质谱(ICP-MS)对取得的土壤、蛋壳、粪便样品进行了钒(V)、铬(Cr)、锰(Mn)、镍(Ni)、铜(Cu)、锌(Zn)、砷(As)、硒(Se)、镉(Cd)和铅(Pb)等10种重金属元素含量的测定,并且对大屿岛上人工饲养的黄嘴白鹭的脱羽进行了研究。 为了研究黄嘴白鹭集群繁殖对营巢区土壤重金属累积的影响,我们对小菜屿2008年~2011年繁殖前后的非巢区和营巢区土壤中的重金属含量进行了测定和分析。营巢区繁殖后土壤中重金属含量与营巢区繁殖前土壤相比,有差异性的元素逐年增加 ...
