Attachment and stress regulation in socioeconomically disadvantaged children: Can public childcare compensate?

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 42, Issue 6, Page 839-850, November/December 2021., 2021
Abstract Children growing up in families experiencing socioeconomic disadvantage (SED) are at greater risk for deficits in attachment and stress regulation as compared to peers in families with more socioeconomic resources. The present study hypothesized that care providers in out‐of‐home care might help these children to compensate.

光照对哺乳动物学习和记忆的影响及其机制研究进展

open access: yes野生动物学报, 2022
综述光照对哺乳动物学习和记忆的影响及其基础机制的结果表明,强光照刺激可以引起哺乳动物昼夜节律紊乱、生理性节律紊乱、睡眠节律紊乱、视网膜损伤和激素分泌紊乱等,并导致空间学习记忆障碍。其中昼夜节律紊乱、视网膜损伤、激素分泌紊乱、突触可塑性过低和内在光敏感视网膜神经节细胞介导可能是强光照刺激引起哺乳动物机体认知障碍的主要机制。研究结果可为进一步研究强光照对哺乳动物学习和记忆的影响提供理论依据。

基于红外相机技术对中华斑羚活动节律的研究

open access: yes野生动物学报, 2022
动物行为是动物对外界环境变化和内在生理活动改变所做出的整体性反应,动物行为节律研究是了解其活动特征时空变化及影响因素的重要内容。因此,于2017年3月—2018年12月采用红外相机监测技术,在药山国家级自然保护区布设了45台红外相机对中华斑羚(Naemorhedus griseus)的日活动节律进行研究。结果表明:中华斑羚的活动具有明显的晨昏性,活动模式呈经典的双峰型,上午的活动高峰出现在06:00—09:00,活动的最高峰出现在09:00,下午的活动高峰出现在16:00—20:00 ...

佛坪国家级自然保护区大熊猫与潜在捕食者的时空动态

open access: yes野生动物学报, 2022
了解同域分布物种的行为活动在空间和时间上的分化,从群体行为上判断其生态位分化,是揭示其共存机制的重要途径。为了探明秦岭大熊猫(Ailuropoda melanoleuca)与同域分布的金钱豹(Panthera pardus)、黄喉貂(Martes flavigula)和豹猫(Prionailurus bengalensis)3种潜在捕食者的日活动节律、时空生态位及共存机制,于2017年1月—2019年12月在陕西佛坪国家级自然保护区利用红外相机技术开展监测。相关监测数据采用核密度估计 ...

关于人的记忆日节律的研究 [PDF]

open access: yes, 1986
在生物组织几乎所有的水平都存在生物节律,其频率范围很大,高达几毫秒一次,低至数年一次。在各种生物节律中,研究得最多的是以约24小时为周期的似“昼夜节律”(“Circadianrhythms”),常被简称作昼夜节律。人体多种生理功能的节律周期是接近一个昼夜,如体温、血压、代谢变化和激素分泌等。近期,有人研究证明,如果没有环境昼夜信号的影响,人体“自由运行”(“free run”)的节律周期略长于24小时 ...
