Integrating adult occurrence and reproduction data to identify conservation measures for amphibians
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Monitoring programs are pivotal to establishing sound management. Due to economic, logistic, and time limitations, monitoring programs often overlook differences among life‐history stages. However, species occurrence does not necessarily mean population viability, and it is unclear to what extent monitoring programs that do not consider ...

Integrative Conservation, Volume 3, Issue 4, Page 368-381, December 2024.Lack of species information complicates understanding climate change vulnerability, but life history traits can be proxies for missing information. In the north‐central United States, useful traits for discriminating vulnerability of amphibians include range size, clutch size, diel activity patterns, and habitat breadth.

野生动物学报, 2013 2002年始,在江苏大丰麋鹿国家级自然保护区持续观测到东方白鹳。2006年一些东方白鹳个体开始在保护区内繁殖,但至今仅2010年繁殖成功。为了解该物种在保护区内的种群繁殖特征,2010年2～6月,对繁殖期东方白鹳亲鸟的行为进行了观察,并测量了巢和巢址参数,结果如下:东方白鹳的2个巢都筑在刺槐树上,巢材为附近植物的条枝,巢内有内垫物。巢周围生境为狼尾草,巢区面积7.2 hm。。繁殖不同时期,在巢、翻卵、育雏3种行为差异极显著 ...

Linking extinction risk to the economic and nutritional value of sharks in small‐scale fisheries
Conservation Biology, Volume 38, Issue 6, December 2024.Abstract To achieve sustainable shark fisheries, it is key to understand not only the biological drivers and environmental consequences of overfishing, but also the social and economic drivers of fisher behavior. The extinction risk of sharks is highest in coastal tropical waters, where small‐scale fisheries are most prevalent.

野生动物学报, 2010 为了对非洲白犀牛进行有效的饲养与繁殖管理,在浙江省杭州野生动物世界对非洲白犀牛的饲养情况进行了说明。此外,还对白犀牛的繁殖分娩行为作了介绍,这也是我国人工饲养条件下,白犀牛成功繁殖后代的首例。本文通过揭示亚成体犀牛生长发育到成体犀牛并交配、繁殖、分娩的过程,同时对习性进行了记录整理,供同行参考。
