圈养亚成体大熊猫（Ailuropoda melanoleuca）春、夏季行为节律的研究
野生动物学报, 2013 2010年2～6月,应用瞬时扫描取样法对上海动物园10只圈养亚成体大熊猫的行为分配和节律进行研究研究结果表明,圈养亚成体大熊猫的行为组成以取食和休息为主。春季,亚成体大熊猫取食行为频次高于夏季,而休息行为频次则低于夏季,春夏两季的行为总体分配间没有显著差异;从行为节律来看,圈养亚成体大熊猫的行为均呈现非正态特征。走动行为主要集中于7:00～8:00和13:00～15:00,攀爬行为主要出现于12:00之后,玩耍行为以13:00～14:00为主;亚成体大熊猫的部分行为之间存在相关性 ...

野生动物学报蹄部疾病是圈养象健康与福利的常见隐患，其中蹄甲开裂易引发继发感染并损害运动功能，严重影响其生存质量。本报告详细记录了一例圈养雄性非洲象（Loxodonta africana）严重蹄甲开裂病例的综合诊疗过程。该病例于2024年1月在北京动物园确诊，其左前肢中趾见一长达60 mm的纵向蹄甲开裂。治疗采用以荧光生物调节疗法（肤维安PHOVIA系统，蓝光波长440～460 nm）为核心的综合方案，每周治疗1次，共20次，并辅以绿勒修蹄喷剂局部护理、祖诺消毒剂环境与蹄部消毒，同时优化饲养环境和行为干预 ...

Optical spectrum of the post-AGB Star HD56126 in the wavelength interval 4010-8790 Å Å [PDF]
Astrophysical Bulletin, 2007 The optical spectrum of the post-AGB star HD56126 identified with the infrared source IRAS07134+1005 is studied in detail using high spectral resolution observations (R = 25000 and 60000) performed with the echelle spectrographs of the 6-m telescope. A total of about one and a half thousand absorptions of neutral atoms and ions, absorption bands of C2,

Measurement of the A-Value of the Intersystem Transition in Al II at 2670 Å: Å Progress Report [PDF]
International Astronomical Union Colloquium, 1984 Ratios of intensities of spectral lines produced in the radiative decay of collisionally-excited levels of atomic ions are versatile indicators of electron density in astrophysical plasmas when one of the lines involves a metastable level (see the review by Feldman 1981 and references therein). Radiative transition probabilities (A-values) and electron

Wildlife Letters, Volume 1, Issue 4, Page 163-170, December 2023., 2023 Per‐ and polyfluoroalkyl substances (PFASs), especially long‐chain perfluorinated carboxylates and perfluorinated sulfonic acids, were considered as global environmental contaminants due to their wide industrial and commercial applications and their threat to human and animal health.

A review to the methods of personality measurements in wild animals 野生动物个性测量方法的综述
Wildlife Letters, Volume 1, Issue 3, Page 131-142, September 2023., 2023 One of the challenges in animal personality study is finding a suitable method to measure personality. Here, we outlined three methods (traits rating, behavioral coding, and experimentation) used in animal personality measurement. We found that traits rating was commonly used to test large‐sized animals (e.g., primates), behavioral coding was conducted

Conservation Biology, Volume 37, Issue 4, August 2023., 2023 Abstract Inner phenomena, such as personal motivations for pursuing sustainability, may be critical levers for improving conservation outcomes. Most conservation research and policies, however, focus on external phenomena (e.g., ecological change or economic processes). We explored the factors shaping 9 conservation attitudes toward forest and wildlife

Association of reproductive traits with captive‐ versus wild‐sourced birds in trade
Conservation Biology, Volume 37, Issue 4, August 2023., 2023 Abstract The wildlife trade is a billion‐dollar global business, involving millions of people, thousands of species, and hundreds of millions of individual organisms. Unravelling whether trade targets reproductively distinct species and whether this preference varies between captive‐ and wild‐sourced species is a crucial question.

Conservation Biology, Volume 37, Issue 2, April 2023., 2023 Abstract Managed breeding programs are an important tool in marsupial conservation efforts but may be costly and have adverse genetic effects in unavoidably small captive colonies. Biobanking and assisted reproductive technologies (ARTs) could help overcome these challenges, but further demonstration of their potential is required to improve uptake. We

Bibliometric investigation of the integration of animal personality in conservation contexts
Conservation Biology, Volume 37, Issue 2, April 2023., 2023 Abstract Consistent individual differences in behavior, commonly termed animal personality, are a widespread phenomenon across taxa that have important consequences for fitness, natural selection, and trophic interactions. Animal personality research may prove useful in several conservation contexts, but which contexts remains to be determined.
