北美浣熊的饲养管理和繁殖

open access: yes野生动物学报, 2013
动物园饲养的浣熊科动物经常出现异常的繁殖行为:食仔和弃仔现象,而随后的人工哺育需要耗费大量时间和精力。2011年上海动物园新引进3对亚成体浣熊,在参考国内外文献资料中浣熊的野外繁殖习性的基础上,在圈养条件下探索降低异常繁殖行为的方法,于2012年首次使3对浣熊成功繁殖和育幼。本文就北美浣熊的野外习性、饲养管理、繁殖特性等,结合观察到的一窝幼仔的发育情况和行为表现做初步小结,以期为今后的繁殖工作打下基础,减少动物的异常繁殖行为。

Facilitating Large‐Scale Bird Biodiversity Data Collection in Citizen Science: ‘Relaxed’ Point Counts for Anytime, Anywhere Monitoring

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This paper proposes a ‘relaxed’ point‐count survey method to enhance accessibility and expand geographic coverage by easing these constraints. Surveys can be conducted in diverse locations, including urban areas and travel routes, within flexible timeframes (e.g., 6 h after sunrise or during the evening) and with adaptable spacing between survey points,

提高栏养条件下普氏野马繁殖率的主要措施

open access: yes野生动物学报, 1992
新疆野马繁殖中心从1987年开始进行普氏野马的饲养繁殖工作,经过4年的摸索,在栏养条件下繁殖取得了初步的成功。3年共繁殖野马14匹,已引起了世界的关注。本文综述了野马中心在提高繁殖率方面所采取的具体措施。普氏野马(Equns przewalskii Poliakov)是濒危物种,在中国已经绝迹。从1985年8月起新疆先后引进普氏野马16匹(6公,10母),在新疆吉木萨尔县境内,建立了新疆野马饲养繁殖中心 ...

Mechanistic study on mercury or cadmium toxicity in marine copepod Tigriopus japonicus under multigenerational exposure [PDF]

open access: yes, 2016
如今,海洋重金属污染已是最严峻的环境问题之一,会对海洋生态系统乃至人类造成巨大的危害,其中汞和镉是最有代表性的重金属,两者即使在低剂量下也会对海洋生物产生较高的毒性效应,而且会在生物体内累积并在食物链传递过程中有生物放大现象,最终威胁人类健康和生命安全。海洋桡足类日本虎斑猛水蚤(Tigriopusjaponicus),因其广泛的地理分布、相对短的世代周期、高的繁殖力、易于区分的雌雄形态及在海洋环境中重要的生态位等,已成为海洋生态毒理学研究的重要模式生物。因此本论文选取日本虎斑猛水蚤作为受试生物 ...

Global drivers of the conservation–invasion paradox

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract The conservation–invasion paradox (CIP) refers to a long‐term phenomenon wherein species threatened in their native range can sustain viable populations when introduced to other regions. Understanding the drivers of CIP is helpful for conserving threatened species and managing invasive species, which is unfortunately still lacking. We compiled

Assessment of the Threat Status of Bent‐Toed Geckos (Cyrtodactylus) in Indochina: Implementation of the One Plan Approach

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 464-475, September 2025.
This study investigates the diversity, conservation status, distribution, and discovery rate of 84 Cyrtodactylus species in Indochina. Despite rising discovery rates, many species are unassessed, with over half unprotected and 90.5% endemic. This study suggests expanding protected areas and implementing an integrated approach to conservation with IUCN ...

Effects of the Grazing Exclusion Policy on Pheasant Nesting Success and Predation Risk in the Protected Areas of Southwestern China 森林禁牧对中国西南保护区雉类繁殖成功率与捕食风险的影响研究

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 381-392, September 2025.
Grazing bans improved vegetation but increased predator activity, reducing pheasant nesting success in Giant Panda National Park—highlighting trade‐offs in conservation policy. ABSTRACT Grazing has a profound impact on forest ecosystems and biodiversity.

繁殖期与非繁殖期麝鼠香腺中Atg2a和Atg9b基因转录水平分析

open access: yes野生动物学报, 2018
麝鼠是一种有很高经济价值的皮、香两用经济动物,其香腺发育机制至今未能阐明。本研究通过RT-qPCR检测繁殖期与非繁殖期麝鼠香腺中Atg2a和Atg9b基因的转录水平,结果显示非繁殖期两者转录水平分别约为繁殖期的43.7倍和16.6倍,提示麝鼠非繁殖期时香腺组织自噬水平增高。进而推测自噬机制在麝鼠非繁殖期香腺萎缩的过程中起到了重要的调节作用。

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 ...
