Using life history traits to assess climate change vulnerability in understudied species 利用生活史特征评估研究不足物种的气候变化脆弱性

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.

Prospects for conserving freshwater fish biodiversity in the Anthropocene: A view from Southern China 人类世下淡水鱼类生物多样性保护的前景:以中国南方为视角

Integrative Conservation, Volume 3, Issue 4, Page 294-311, December 2024.
Freshwater biodiversity in China is threatened by multiple anthropogenic factors, and while there are some reasons to suppose it may be possible to bend the curve of biodiversity loss, the variety of threats and their likely interactions with ongoing climate change provide little basis for optimism. For example, the historic overexploitation of Yangtze

Conservation Biology, Volume 38, Issue 6, December 2024.
Abstract In Assam state, northeastern India, human–elephant conflict mitigation has included technocentric measures, such as installation of barriers, alternative livelihoods, and afforestation. Such measures treat conflict as a technical problem with linear cause–effect relations and are usually ineffective over the long term because they do not ...

笼养绿孔雀繁殖期行为观察

野生动物学报, 2007
采用扫描取样法对秦皇岛野生动物园40只笼养绿孔雀繁殖期的行为进行了为期58d,325h的观察,结果显示繁殖期各行为所占的比例分别为休息31.31%、取食22.03%、理羽16.37%、游走15.93%、警戒9.79%和繁殖4.59%。方差分析和μ检验表明:天气状况对笼养绿孔雀的休息、取食、理羽和游走行为的时间分配的影响明显,但对繁殖和警戒行为影响不大。

人工饲养白枕鹤繁殖期行为观察

野生动物学报, 2007
本研究对笼养白枕鹤行为进行观察记录和分析,结果表明笼养白枕鹤繁殖期行为日活动节律依次为休息（32.15%）、取食（30.02%）、理羽（12.92%）、警戒（12.14%）、游走（8.86%）、繁殖（3.90%）,另外,繁殖期的不同时期、不同性别其行为时间分配都存在一定差异。人为干扰,邻近笼舍内东方白鹳的干扰,以及外界噪音的干扰对笼养白枕鹤繁殖期行为影响十分显著。同时气候条件以及温度变化对笼养白枕鹤总体行为亦存在一定影响。
