Flexible parental care in a songbird correlates with sex-specific responses to seasonal phenology, mating opportunity and reproductive success. [PDF]

J Anim Ecol
This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony-specific population trajectories at South Georgia. [PDF]

Conserv Biol
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle. [PDF]

Conserv Biol
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

麝鼠TNFRSF13C和TNFRSF4基因表达分析

野生动物学报, 2020
麝鼠（Ondatra zibethicus）是一种珍贵的毛皮动物和香料动物，在繁殖季节能分泌麝鼠香，而其香腺泌香机制尚不清楚。TNFRSF13C（BAFF受体）和TNFRSF4（OX40受体）基因是TNF受体超家族的成员，参与免疫调节、炎症、凋亡，还与自身免疫病和多种器官的形成有关。本研究通过RT-qPCR技术检测繁殖期与非繁殖期麝鼠的心、肝、肺、肾、睾丸、肌肉及香腺中TNFRSF13C和TNFRSF4基因的转录水平，结果显示两者在繁殖期和非繁殖期7个组织中均有表达，在繁殖期麝鼠的心、肝、肺、肾、睾丸 ...

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

Wildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Updates on Breeding Success and Conservation Challenges for White‐Rumped Vulture (Gyps bengalensis) in Rampur Valley, Nepal 尼泊尔兰普尔山谷白腰兀鹫繁殖成功研究进展及其保护挑战

Wildlife Letters, EarlyView.
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.

When and why to give shorebirds a head start

Conservation Biology, EarlyView.
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

Genomics‐informed management of ex situ populations

Conservation Biology, EarlyView.
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

Conservation Biology, Volume 40, Issue 5, October 2026.
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 ...
