In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Conservation Biology, EarlyView.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

野生动物学报, 1985 近二十年来,灵长类养殖业迅速发展,遍及世界各地的养猴场采用了多种形式进行种群繁殖,其中有自然保护区人工驯化繁殖、天然岛半放养繁殖、猴园繁殖和小群笼养繁殖等。尽管各种繁殖方式的管理细则有所差别,但原则是共同的。现以猕猴（Macaca mulatta）小群笼养繁殖（即一个笼舍养1♂与5—8♀常年同居配种）为例,现将管理体会介绍于后。繁殖猴群的管理大致可分为种猴选择、

Optimization of mixed fermentation technology of Lactobacillus helveticus andLactobacillus rhamnosus based on high viable count [PDF]
, 2016 以瑞士乳杆菌和鼠李糖乳杆菌混合发酵培养,利用两菌株细胞代谢的差异,以静置发酵24 h后得到的活菌数目为指标,通过单因素实验和正交实验,研究了瑞士乳杆菌和鼠李糖乳杆菌高活菌数混合发酵的最适发酵条件。结果表明,瑞士乳杆菌和鼠李糖乳杆菌高活菌数混合发酵的最优条件为:发酵温度37℃,初始pH=6.8,接种量6%,瑞士乳杆菌:鼠李糖乳杆菌=1∶2,瑞士乳杆菌优先接种3 h。最终得到乳酸菌总活菌数为7.2×10~9m L~(-1)。与在相同条件下单独发酵的瑞士乳杆菌和鼠李糖乳杆菌活菌数相比,分别提高了1∶8倍和10.

野生动物学报, 2017 2014年5月至2014年10月间,在青海省海北自治州祁连县野牛沟乡达玉村附近,从动态的角度研究高原鼠兔在其生境地繁殖季节前后血常规、血气和性激素的变化,并与繁殖期间的各种环境因子相关联,探讨鼠兔繁殖策略对环境及行为的响应。结果表明,可将该地区高原鼠兔的繁殖期分为过渡恢复阶段(5月以前); 繁殖旺盛阶段(5月下旬～7月中旬); 繁殖抑制阶段(7月下旬～9月下旬); 繁殖静止阶段(10月及10月以后)4个阶段,不同的繁殖阶段高原鼠兔在体重、繁殖指数、血常规指标、血气指标、睾丸相对重量 ...

Integrative Conservation, Volume 4, Issue 4, Page 600-615, December 2025.Only 1541 (34.2%) of 4503 recognized non‐passerine bird species are held in ZIMS institutions worldwide. Approximately ~83% of the species kept globally are classified as non‐threatened and ~16% as threatened. To improve the conservation of threatened birds, a shift toward keeping threatened species should be considered within ex situ management ...

野生动物学报, 2013 采用瞬时取样法对圈养的2对蓝鹇和2组白鹇繁殖期行为的时间节律进行了初步研究,分别选择蓝鹇和白鹇繁殖行为较为明显的时期,各记录15 d,即蓝鹇为2008年3月30日～4月15日（12、13日因故未观察）,白鹇为2008年4月16～30日;每天观察12 h,即从7:00～19:00。结果表明第一组蓝鹇和白鹇的繁殖行为都明显少于第二组蓝鹇和白鹇,蓝鹇和白鹇的繁殖行为的发生次数随日期出现波动,两物种繁殖行为的高峰多在早晚时段。蓝鹇和白鹇的产蛋周期分别为3～4 d和1～3 d ...

Integrative Conservation, Volume 4, Issue 4, Page 523-526, December 2025.Here we report three cases of nesting behavior in Yunnan Province, China. Our observations confirmed the presence of multi‐individual participation during the nest guarding, and this behavior was associated with an exceptionally high clutch size. ABSTRACT Although the King Cobra (Ophiophagus hannah) has received considerable conservation attention ...

野生动物学报, 2000 在笼养情况下,东北虎（Pantheratigris altaica）的饲养繁殖报道很多,但大群散放情况下的繁殖行为观察还少见报道.我园自1995年建园以来,在散放东北虎的饲养管理和繁殖方面积累了一些经验.从1998年第一例繁殖成功至今,共繁殖30多只东北虎.期间,我们对东北虎的繁殖行为进行了较详细的观察,现总结如下.
