野生动物学报, 2007 迁地保护的海南坡鹿种群可以分为野放、半野放和圈养等3种主要类型。野放种群个体数量最多,约占迁地保护种群个体总数的55．3％;其次为半野放种群,其个体数量占35．6％;圈养种群个体数量最少,只占9．1％。半野放是一种较为稳妥的坡鹿种群恢复方式。在海南坡鹿的迁地保护中,应该增加半野放种群个体数量。本文就海南坡鹿的迁地保护提出了7点保护管理及科学研究建议。

野生动物学报, 2020 麋鹿自1985年重引进中国以来,经过繁殖扩群、行为再塑和野生放养试验3个阶段后,种群数量从79头发展至近7 000头(2018年底),先后形成江苏大丰、湖北石首和湖南洞庭湖野生麋鹿种群。通过对中国麋鹿种群发展现状调查分析,指出目前麋鹿种群健康发展面临的挑战和威胁因素,在扩大奠基种群数量、实施栖息地正向干预、加强疫病防控、开展基因交流等方面探讨中国麋鹿种群健康发展对策。

Conservation Biology, EarlyView.Abstract As nations seek to expand protected area (PA) networks to cover 30% of land and seas by 2030 (30×30), there is an urgent need for systematic conservation planning and spatial prioritization that considers the broad range of ecological and socioeconomic factors influencing the persistence of biodiversity.

Vulnerability of tropical fish communities across depth in the central Indian Ocean
Conservation Biology, EarlyView.Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

野生动物学报, 2015 对中国白头鹤圈养种群的统计学和遗传学结果进行了相关分析,并对种群数量、年龄结构、性比情况、基因多样性、近交系数以及未来100 a种群的发展趋势进行了重点研究。结果表明:截止到2013年12月31日,中国圈养白头鹤种群共有存活个体76只,分别饲养于15家单位,其中建立者的数量为16只,潜在建立者的数量为41只。圈养白头鹤种群中育龄个体充足,但幼龄个体数量不足,种群年龄结构不是很合理。白头鹤种群保留了野生个体92.9%的基因多样性,平均近亲系数为0,是一个没有任何近亲繁殖的优质种群。通过分析发现 ...

Conservation Biology, EarlyView.Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots
Conservation Biology, EarlyView.Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

野生动物学报, 2009 对扎龙湿地的水鸟群落进行资源调查,共记录水禽52种,隶属于5目11科。其中古北界种类42种（占82%）,广布种类10种（占18%）,东洋界种类无记录。对结果进行分析发现:扎龙自然保护区水鸟群落种类和数量随着迁徙活动呈现了明显的季节性变化。春季水鸟迁徙时间集中,种群数量变化剧烈,有高峰期;秋季水鸟迁徙时间分散,种群数量变化缓和,无明显的高峰期。

Heart rate variability in horses with and without severe equine asthma
Equine Veterinary Journal, Volume 57, Issue 3, Page 611-618, May 2025.Abstract Background Equine asthma in severe form (severe equine asthma [sEA]) shares remarkable similarities with human asthma. Human studies detected changes in the autonomic nervous system function in asthmatic patients based on heart rate variability (HRV) analysis. Study design Observational study. Objectives To investigate the relationship between
