野生动物学报, 2006 通过统计1959-2005年关于大鸨的研究文献,分别从就地保护、迁地保护两个方面进行分析。结果表明:有关大鸨的研究虽从1959年开始,但直到80年代才逐渐形成系统,其中,就地保护研究数量（67．2％）多于迁地保护的研究数量（32．8％）。迁地保护和就地保护都存在研究内容比较基础的问题。在大鸨的就地保护中,保护区没有真正发挥其功效;大鸨迁地保护工作虽取得一定成就,能够保持人工饲养种群数量的基本稳定,但人工繁育技术只在部分地区取得成功,另外,应激和疾病仍是影响大鸨迁地保护工作的主要因素 ...

Setting goals for pollinator gardens
Conservation Biology, EarlyView.Abstract In recent years, declines in animal pollinators have stimulated tremendous interest in pollinator‐friendly gardening. There is a widespread notion that pollinator gardens are beneficial, but the specific capacity of pollinator gardens to improve biodiversity conservation and societal well‐being remains unclear.

野生动物学报, 2006 黑龙江地处中俄边界,在流域内中俄积极开展保护合作。本文分析了中俄在黑龙江两侧的保护区类型、保护对象,结果表明黑龙江流域的众保护区具有共同的保护对象,保护区的类型也惊人的相似。这些相同相似之处对于中俄保护合作深入发展有重要义。

Conservation Biology, EarlyView.Abstract Primates, 69% of which are threatened with extinction, are the third most specious order of mammals. We used primates as model taxa to examine the umbrella effects of primates on ecosystem services and the protection of other vertebrates and seed plants in Yunnan Province, China.

野生动物学报, 2017 江西鄱阳湖南矶湿地国家级自然保护区位于鄱阳湖主湖区南部,赣江入鄱阳湖的三角洲水域。其特殊的地理位置孕育了非常丰富的鱼类资源和生物多样性,是许多迁徙水鸟的重要越冬地。保护区成立后湿地资源虽得到有效保护,但如何正确处理渔业生产和资源保护的问题,一直困扰保护区管理者。为缓解社区矛盾,保护区开展了“点鸟奖湖”等一系列活动,补偿社区渔民损失。通过这些活动,提高社区民众参与保护鸟类的热情,建立保护区管理者和社区民众的互信,达到保护与发展双赢的效果。关系到社区居民的发展是所有保护区管理人员必需考虑到的问题,“点鸟奖湖”

Using online reports of seahorse seizures to track their illegal trade
Conservation Biology, EarlyView.Abstract Illegal wildlife trade (IWT) is a persistent and extensive threat to global biodiversity. Hundreds of marine fish species are subject to regulation under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but it is unclear how much protection species gain from CITES because information on marine fish ...

Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States
Conservation Biology, EarlyView.Abstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the

野生动物学报, 2010 2008年6月,对广东大峡谷自然保护区社区公众野生动物保护意识进行了问卷调查。结果表明:（1）公众对野生动物保护知识匮乏,缺乏野生动物保护法制意识;（2）公众普遍对野生动物面临的威胁有较明确的认识,具有保护意愿,但缺乏保护野生动物的积极性和主动性;（3）公众接受野生动物保护教育的主要途径是电视。本文针对广东大峡谷自然保护区公众野生动物保护意识现状及其存在的问题,提出了一些建议。

On the normative roles of biodiversity and naturalness in conservation
Conservation Biology, EarlyView.Abstract Nature is an opaque concept. Consequently, the term biodiversity conservation has replaced nature conservation in most conservation contexts. We review the conceptual indeterminacies that plague the terms nature and natural but then show that comparable difficulties plague biodiversity.
