, 2019 生物钟是生物体对环境长期适应而形成的自主计时机制。生物钟基因调节人体多项生理活动，比如睡眠-觉醒、激素分泌、细胞代谢和免疫调节等，其目标是使细胞、组织以及器官能够有序、协同作用，并呈现明显的节律。女性生殖功能受下丘脑-垂体-卵巢轴的昼夜节律调控。由于外界因素引起的昼夜节律中断与女性各种生殖功能障碍的发生发展有关，包括月经失调、流产和生育力下降等。本文旨在从月经周期中卵泡发育的调控、排卵 ...

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 ...

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.
