野生动物学报, 2020 贮食行为是动物在应对环境变化为度过食物短缺期，或为交配、繁殖后代而储备食物的生存策略。为探究季节性环境因子变化和食物资源对黑线仓鼠（Cricetulus barabensis）贮食行为的影响，本文测定了温度光周期、动物性别、限食对该物种贮食量、摄食量、体重等指标的影响。结果显示，雄性黑线仓鼠的体重、摄食量及贮食量均显著高于雌性；在类似于晚秋的低温等光照（10 ℃±2 ℃，L∶D=12∶12）条件下驯化1周，会诱导雄性个体体重降低，但摄食量不变，雌性个体则增加摄食量维持体重不变，雌雄的贮食量均不变 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2023 目的调查学龄前儿童饮食行为现状，探究家庭亲密度和适应性与其之间的关系。方法以2021年9月至2021年12月深圳市坪山区21 954名学龄前儿童及家庭为研究对象，采用问卷收集一般人口学资料，并采用家庭亲密度与适应性量表、学龄前儿童饮食行为量表收集相关信息。采用多重线性回归分析家庭亲密度和适应性与学龄前儿童饮食行为之间的关系。结果家庭亲密度类型和适应性类型与饮食行为的七个维度：挑食（R2=0.252， F=114.457， P<0.001）、食物响应（R2 = 0.111， F=24.973， P ...

Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Psychometric framework for coexistence with large carnivores
Conservation Biology, EarlyView.Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...

Conservation Biology, EarlyView.Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...

Zhongguo shiyan zhenduanxue, 2011 目的探讨食物特异性IgG抗体与儿童过敏性紫癜的相关性。方法采用ELISA方法检测209例儿童过敏性紫癜患者血清中13种食物特异性IgG抗体。结果 209例过敏性紫癜患儿中有139例检测到1-13种食物特异性IgG阳性升高,总阳性率为66.5%（139/209）;特异性IgG阳性率较高（10%以上）的主要致敏食物有2种,分别为鸡蛋（39.2%）和牛奶（38.8%）;食物特异性IgG浓度分级结果表明,鸡蛋和牛奶均可引起不同程度的食物不耐受,而其余多数食物则以引起轻度不耐受（即IgG浓度为+1级）为主 ...

World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT Household food expenditure continues to be a key factor in ensuring the realization of the Human Right to Adequate Food. Particularly in Brazil, access to food can be limited by economic constraints in vulnerable families, especially among farming families, who have been more vulnerable to food insecurity in recent years in the country.

野生动物学报, 1992 确定食物选择性不仅是估计动物生境营养容纳量和进行生境评价及改良等种群管理学问题的基础,它也将为生境选择、建立最优取食模型和探讨种间关系等许多生态学方面的问题提供有价值的信息,因此成为食性研究中一项主要的工作。在国外,食物选择性（food selectivity）这一术语在食性研究中通常与食物偏爱性（food preference）相混淆,在食性文献中常为后者所代替。在国内,食物选择性的确定仅在最近的有蹄类食性研究中得到重视（陈化鹏等1989）,并且在已往的食性研究中,主要食物（Principal ...

The Making of the Right to Food: Tracing Food Policy Conflict and Negotiated Outcomes in Colombia
World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT The 2016 Peace Agreement between the Colombian Government and the FARC guerrilla group marked a historic step toward ending more than five decades of armed conflict. It also reshaped national food policy with lasting implications. During the negotiations, deep ideological divisions emerged between food sovereignty and food security, and these ...
