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.We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.

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‐

Wildlife Letters, EarlyView.FoxWatch is a user‐friendly analytical workflow that converts camera‐trap detections into dependable estimates of fox abundance. The user‐friendly Shiny R app standardizes data preparation, employs Simultaneous‐Count Models modeling, and displays uncertainty in clear, comprehensible outputs. By connecting field monitoring with decision‐making, FoxWatch

Wildlife Letters, EarlyView.Common cuckoo nestlings from different populations show varying degrees of mimicry of warbler begging calls, with the Yongnianwa population being the most accurate and the Zhalong population the least. Overall, these cuckoos employ a dual strategy: they conservatively mimic the high‐frequency components of host calls while adaptively adjusting their ...

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 ...

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.

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。

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Atmospheric nitrogen deposition disrupts plant–herbivore interactions, but its impact on leaf volatile organic compounds (VOCs)‐mediated multi‐trophic herbivore resistance remains unclear within the context of plant invasion. In this study, we initially investigated the

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 ...
