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 ...

野生动物学报, 2021 2019年4—10月，利用访问调查法和样方调查法对海南长臂猿（Nomascus hainanus）食源植物展开调查，确定了海南长臂猿食源植物组成及其季节性变化。研究表明，海南长臂猿采食的食源植物有166种，隶属于52科99属。在雨季（5—10月），海南长臂猿食源植物有47科88属148种。在旱季（11月至翌年4月），海南长臂猿食源植物有39科61属90种。在雨季，海南长臂猿可采食成熟果实的植物种类较多，相对更容易获得食物。而在旱季能够取食果实的植物种类减少，结果量较低、且分布不集中 ...

Wildlife Letters, EarlyView.By comparing widespread surveys with randomly placed cameras to a protocol pairing detection dogs with cameras, we found that the detection‐dog‐guided camera survey had approximately 33 times greater detections with fewer camera nights and reduced survey costs. We recommend using detection dogs to identify areas to focus camera trapping. ABSTRACT Multi‐

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowers with deep corollas are frequently associated with nectar robbing, a behaviour that often reduces pollen transfer and seed production. Robbing scars, however, may further affect plant reproductive success through rainwater entry into corolla tubes.

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 ...

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 ...

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, 2018 食管炎是临床上最常见的食管疾病,一般是由食管黏膜受到刺激或者损伤,继而引发食管黏膜充血水肿所致。根据病因不同可以分为反流性食管炎、真菌性食管炎、病毒性食管炎、化脓性食管炎等,其中真菌性食管炎是特殊的食道炎症,主要由于霉菌侵入食管粘膜组织导致食管感染,属消化道念珠菌病之一。食管破裂是食管病变的严重并发症,病情严重者可能引起穿孔,继而导致纵膈感染,病情进展迅速,预后不良,甚至死亡[1]。食管炎并发食管破裂者极其罕见,我院收治1例食管炎并发食管破裂、感染性休克的患者,现报告如下。

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.
