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 287-301, September 2025.Qilianshan National Park covers approximately 40% of core snow leopard habitat patches and 50% of movement corridors between patches. Including more of these important areas within the park boundaries should be considered, as the Qilianshan National Park sits at a pivotal juncture between critical snow leopard habitat in China and Mongolia, and may ...

, 2013 动物常依据捕食风险强弱改变其行为策略,在警戒与采食及其它行为的时间分配上权衡,这一理论称为捕食风险的时间分配假说.该假说已在高原鼠兔等动物中得到验证,但对在中亚荒漠地区有代表性的啮齿动物大沙鼠(Rhombomys opimus)是否成立至今未被验证.通过行为观察,比较警戒与采食等行为在单位观察时间内总累积时间、单次行为持续时间以及活动频次之间的关系,验证大沙鼠行为规律是否符合捕食风险的行为时间分配假说.结果显示大沙鼠警戒行为的总累积时间与采食等其它行为间存在显著负相关(警戒与总地表活动:r =-0 ...

Integrative Conservation, Volume 4, Issue 3, Page 405-415, September 2025.Assessing the genetic diversity of edible insects harvested from the wild is a pre‐requisite for designing conservation and management policies. The caterpillars of Gynanisa maja (Saturniidae) are harvested in large numbers in mopane woodlands in southern Africa, where they represent a seasonal source of income and nutrition to many rural communities ...

塔里木马鹿(Cervus elaphus yarkandensis)的食性分析与采食地选择
, 2006 在新疆且末县境内研究了塔里木马鹿(Cervus elaphus yarkandensis)的食性和采食地选择．野外直接观察结合粪便显微分析表明,该亚种共采食15种植物,冬季采食13种植物,夏季采食9种．冬季由于高质量食物缺乏,马鹿采食更多的植物种类．无论在冬季还是夏季,芦苇(Phragmites communis)、胀果甘草(Glycyrrhiza inflata)和胡杨(Populus diversifolia)均为经常采食的3种植物．其中,芦苇在研究区资源最为丰富,是塔里木马鹿最主要的食物 ...

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;

, 2010 社会学习是动物快速获得新行为的有效途径。本研究对鳜稚鱼摄食行为的社会学习进行了检验和分析。将500尾未驯化鱼平均分配到实验组和对照组中,并在实验组中另外加入50尾已驯化鱼作为示范鱼。采用分批投饵方法群体驯化两组实验鱼摄食死饵料鱼,测量两组实验鱼摄食每批死饵料鱼的群体袭击反应时间和群体袭击持续时间。结果显示,实验组的群体袭击反应时间比对照组的稳定;实验组的群体袭击持续时间比对照组的短,且在第1次、5次、6次训练时存在显著差异。由此分析鳜稚鱼具有社会学习能力,示范鱼可能通过局域增强和反应易化社会学习过程 ...

European Policy Analysis, Volume 11, Issue 1, Page 114-137, Winter 2025.Abstract In Europe, and specifically in countries bordering the Baltic Sea, preparedness issues have moved up the policy agenda since Russia's 2014 and 2022 invasions of Ukraine. “Ordinary people” are encouraged to prepare for crises—be it through stockpiling food at home, fact‐checking information, or signing up for military training.
