This study investigates the breeding success of the critically endangered White‐rumped Vulture in Khaireni Community Forest, and examines local knowledge and perceptions toward its conservation. We found that 71% of active nests were successful, with breeding success significantly influenced by the proximity to carcass deposition sites.

Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowers with deep corollas are frequently associated with nectar robbing, a behaviour that often reduces pollen transfer and seed production. Robbing scars, however, may further affect plant reproductive success through rainwater entry into corolla tubes.

When and why to give shorebirds a head start
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

Advancing conservation breeding programs for marine invertebrates
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

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 ...

Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...

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.

Genomics‐informed management of ex situ populations
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

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 ...
