Extent of threats to marine fish from the online aquarium trade in the United States
Conservation Biology, Volume 40, Issue 1, February 2026.The global marine aquarium hobby is a multibillion‐dollar industry, largely driven by demand from the United States. Much of this trade occurs online. We web scraped 4 major US‐based e‐commerce platforms selling marine aquarium fish to determine the retail price and source (wild capture, aquaculture, or both) of 13 families of ray‐finned marine fish ...

野生动物学报, 2013 黑龙江七星河国家级自然保护区位于三江平原腹地,是丹项鹤的重要繁殖地,2011年4～5月对保护区繁殖前期的丹顶鹤孵化行为进行了观察,结果表明:丹顶鹤孵化期的各种行为具有较强的规律性,各行为频率依次为:繁殖31.34%、觅食28.26%、警戒20.12%、静栖8.99%、游走4.51%、其他6.78%。在不同繁殖阶段,丹顶鹤各行为的生境分配存在一定差异。在产卵前期,繁殖行为主要发生在芦苇火烧地,觅食行为主要发生在农田;在孵化初期,繁殖行主要发生在苇丛里,觅食行为主要发生在芦苇火烧地。

Taxonomy of Genus Branchiostoma in Xiamen Waters and Continuous Breeding of Two Lancelets in the Laboratory [PDF]
, 2007 文昌鱼是现存无脊椎动物中与脊椎动物直接祖先很相似的一个类群，在动物进化史上占据重要的地位，是进化发育生物学和比较基因组学研究领域的重要模式生物。厦门曾经以盛产文昌鱼并形成世界上唯一的文昌鱼渔场而闻名于世，厦门文昌鱼自1932年被鉴定为白氏文昌鱼BranchiostomabelcheriGray以来一直被认为是同一种，直到2005年应用分子生物学技术进行文昌鱼物种鉴定时，才发现其中包含有2个独立物种，即白氏文昌鱼B.belcheri和日本文昌鱼B.japonicum。本研究详细观察了这2种文昌鱼大量标本 ...

Integrative Conservation, Volume 4, Issue 4, Page 600-615, December 2025.Only 1541 (34.2%) of 4503 recognized non‐passerine bird species are held in ZIMS institutions worldwide. Approximately ~83% of the species kept globally are classified as non‐threatened and ~16% as threatened. To improve the conservation of threatened birds, a shift toward keeping threatened species should be considered within ex situ management ...

Integrative Conservation, Volume 4, Issue 4, Page 523-526, December 2025.Here we report three cases of nesting behavior in Yunnan Province, China. Our observations confirmed the presence of multi‐individual participation during the nest guarding, and this behavior was associated with an exceptionally high clutch size. ABSTRACT Although the King Cobra (Ophiophagus hannah) has received considerable conservation attention ...

, 2007 蜜蜂群体由1只蜂王、几百只雄蜂和数千只工蜂组成,工蜂数量巨大,除蜂王和雄蜂共同完成生殖任务,巢内外活动均由工蜂完成,其行为呈现多样性。工蜂发育经过卵、幼虫、蛹、成虫4个阶段,其活动范围由温度、湿度相对稳定的巢内环境发展到复杂的巢外自然环境。随发育阶段和生活环境的变化,工蜂的生理、行为等方面也发生相应变化,这种变化为综合研究生物行为的分子机理提供了可能。又因工蜂数量多、体积较大易于观察、标记、饲养管理简单,而且目前对其形态、发育、生理、分子生物学、神经、社会生态等各方面的研究比较充分 ...

Dietary selection of ex-situ population in Chinese Egret [PDF]
, 2010 2008年至2009年在厦门大屿岛白鹭自然保护区建立了黄嘴白鹭（Egrettaeulophotes）异地种群，对异地种群进行了行为时间分配的研究。在对野生黄嘴白鹭食性进行初步研究的基础上，对异地圈养个体进行了食物选择性实验，并对食物进行了营养成分分析。目的在于了解了异地饲养条件下黄嘴白鹭的取食规律，并根据最佳摄食理论探讨其取食策略。 2008年和2009年两年共从野外采集69只黄嘴白鹭幼鸟，在厦门大屿岛白鹭自然保护区进行饲养，记录种群的存活情况，摸索相关饲养方法。其三月龄的存活率达到60%以上 ...
