野生动物学报, 2013 2011年4月20日～5月7日,以七星河自然保护区繁殖的白枕鹤为研究对象,采用扫描取样法对孵化期白枕鹤的觅食行为进行了研究。研究结果表明:白枕鹤偏好在芦苇地和苔草地中觅食,多以植物的嫩叶为食。孵化期昼间行为活动时间分配中觅食行为所占时间为39.31%。日节律显示:觅食行为在一天中出现2次高峰,即6:00～8:00和16:00～17:00之间,而在14:00～15:00出现低谷。

A new beef: An analysis of discourse coalitions in the nascent cellular agriculture policy subsystem
Review of Policy Research, Volume 42, Issue 6, Page 1404-1427, November 2025.Abstract A robust approach to examining the nature and influence of coalitions in the policy process is the Advocacy Coalition Framework (ACF), which is especially useful to study policy issues fraught with scientific and technical controversy. Yet, important gaps exist in ACF literature regarding nascent policy subsystems. Consequently, there is scant

Integrative Conservation, Volume 4, Issue 3, Page 302-309, September 2025.We discussed the key assumptions of Distance sampling that were considered hard to meet in mountainous terrains and potential solutions for them. Our survey yielded comparable estimates from distance sampling and double‐observer survey, although the confidence interval from distance sampling was broader.

野生动物学报, 2011 2008年11～12月,在姚家坪小熊猫繁育基地采用目标取样法和瞬时扫描取样法对19只圈养小熊猫指名亚种的活动规律进行了研究。结果表明,圈养小熊猫1d大部分时间用于休息（56.2%）,其次是运动（25.1%）和采食（9.9%）,其余行为分配的时间较短。在行为节律上,休息行为除9:00～9:55外,其余时间均为所占比例最高的行为,出现4个休息高峰,分别为8:00～8:55、11:00～11:55、14:00～14:55和17:00～17:55,在9:00～9:55出现极低值16.3%,此时是运动和采食的高峰;

, 2013 以往研究表明受发情交配行为制约,一些雄性反刍动物在发情期食物摄入量明显降低.已有两个相关假说解释该现象:能量摄入最大化假说和能量保存假说.作者于2009～2010年在卡拉麦里山有蹄类自然保护区研究了雄性鹅喉羚不同发情阶段的时间分配.结果表明雄羚发情期采食时间比例明显下降(37.9％),低于发情前期(63.6％)和发情后期(65.8％)；发情期卧息时间比例(6.0％)与发情后期相近(5.4％),明显低于发情前期(23.2％)；发情前期至发情后期采食卧息时间比(分别为2.7、6.3、12.1)显著增加 ...
