野生动物学报, 2022 为了解栖息地和气候变化对北树鼩（Tupaia belangeri）活动的影响，于2012年8月—2013年7月采用红外相机技术对广西弄岗国家级自然保护区15 hm2森林动态监测样地及其周边区域内的北树鼩进行监测，采用核密度估计、重叠指数及相对活动强度指数分析其日活动节律及季节性变化规律。结果表明：北树鼩的日活动节律模式属于晨昏活动类型（日活动高峰期：07：00—08：00、16：00—17：00）。不同月份间北树鼩的活动强度指数（t=13.072，df=11 ...

Zhejiang Daxue xuebao. Lixue ban, 2005 园林鸟类是城市环境质量的重要指标，也是城市自然保护和生态建设的重要组成部分.1997年10月至1998年12月，通过选取杭州市区20个主要园林，根据季节每月一至两次调查园林鸟类的物种和数量，对杭州市园林鸟类的群落结构及其季节变化进行了分析探讨，结果显示：全部园林中共记录到鸟类82种，其中迁徙鸟类50种，占61%，留鸟32种，占39% ；园林鸟类群落呈现出较强的季节性，从全部园林总体上看，物种数和总数量呈现春秋两个高峰，夏季最低；从单个园林来看，多数园林鸟类群落物种数的最高峰集中在冬季 ...

Integrative Conservation, Volume 5, Issue 1, Page 86-103, March 2026.Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...

Integrative Conservation, Volume 5, Issue 1, Page 74-85, March 2026.This study investigates distribution patterns of Galliforms in the Indian Himalayas, focusing on factors influencing their occurrence, regions of high diversity and endemism, and their overlap with protected areas. Our study highlights the need for assemblage‐level conservation strategies in high Himalaya which primarily relies on snow leopard‐focused ...

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

Zhongguo shiyan zhenduanxue, 2019 目的观察长春市2型糖尿病(T2DM)患者糖化血红蛋白(HbA1c)的冬夏季变化。方法选取2015年12月至2018年9月于吉林大学第二医院就诊的长春市2型糖尿病患者,且病程5年以内、病情稳定者共650人为研究对象,观察其冬季(12月至次年2月)及夏季(7月至9月)的HbA1c值。所有观察对象按冬、夏季分为两组,探究糖化血红蛋白与季节是否具有相关性,同时探究所有观察对象的一般情况及相关代谢指标是否也受季节变化的影响。结果糖化血红蛋白(HbA1c)存在冬季高、夏季低的统计学差别[(9.71±1.84)%比 ...

Integrative Conservation, Volume 4, Issue 4, Page 652-664, December 2025.We profiled nutritional and physiological markers in captive sifakas, endangered primates from Madagascar, managed in expansive, non‐native forest enclosures. Variation in many markers reflects freely foraged diets and the energy required to maintain homeostasis under more naturalistic conditions.

Wildlife Letters, Volume 3, Issue 4, Page 194-202, December 2025.This study establishes the optimal nonlethal laser deterrence range (210–260 W, 1s) for wild boars, preventing agricultural damage while ensuring animal safety. Results demonstrate that efficacy requires seasonal power adjustments (≤ 285 W in winter) and precise targeting control—enabling effective, injury‐free wildlife conflict mitigation.

野生动物学报, 2006 本文通过潘文石对22只秦岭大熊猫的家域观察资料为基础,获得生态年龄段和家域对数转换值等次生数据, 并以次生数据为基础,对不同生态年龄段和不同季节大熊猫的家域和个体季节性迁移面积的动态特征进行定性比较分析,通过季节、性别和年龄对秦岭大熊猫种群家域动态的影响机制进行了探讨,结果发现以下新细节: （1）虽然在同一季节,大熊猫家域面积随着年龄的增长逐渐增加,但雌性个体家域面积增加不大,雄性个体也仅在夏季家域面积增加极大,秋冬季增加也不大; （2）同一生态年龄段,秦岭大熊猫家域面积:全年>秋冬季>夏季; （3 ...
