低温和限食对黑线仓鼠贮食行为的影响

open access: yes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 ...

Local Ecological Knowledge Reveals the Distribution of Cryptic Nocturnal Wildlife 局域生态知识揭示隐秘夜行野生动物的分布

open access: yesWildlife Letters, EarlyView.
Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

Wild Pigs (Sus scrofa) Stand Their Ground: Investigating Flight Response, or Lack Thereof, to Perceived Predation Risk 野猪坚守原地:探究其面对感知捕食风险时的逃逸反应 (或无逃逸行为)

open access: yesWildlife 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.

Detection‐Dog‐Guided Camera Placement Increases Efficiency of Surveys for Long‐Tailed Weasels (Neogale frenata) 利用探测犬引导布设相机可提升长尾鼬调查效率

open access: yesWildlife 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‐

Taxonomic and functional diversity of urban bees of the world

open access: yesConservation 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 ...

儿童过敏性紫癜患者食物特异性IgG抗体检测分析

open access: yesZhongguo 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 ...

在宅療養者とその家族・関係スタッフにおける要食事介護者向けアイスクリーム活用可能性についての検討 [PDF]

open access: yes, 2022
アイスクリームは食欲不振時にも食べやすく,低栄養の改善にも使われるが,溶けやすい性質から嚥下機能低下や喫食に時間を要する場合は提供が難しい。そこで,考案した要食事介護者向けアイスクリームが介護食として活用できるかの可能性を検討するため,訪問栄養食事指導を利用する在宅療養者とその家族・関係スタッフを対象にアイスクリーム喫食後質問紙調査を行い,コレスポンデンス分析ならびにCS分析を行った。在宅療養者26名と家族・関係スタッフ31名の回答結果より,「食べ終わりまでアイスクリームとして楽しめたか」の質問に対して「

食管炎合并食管破裂1例病例报道

open access: yesZhongguo 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。

Psychometric framework for coexistence with large carnivores

open access: yesConservation 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 ...
