Progress on effects of BaP exposure on female reproductive system and pathogenic mechanisms [PDF]
Benzo[a]pyrene (BaP) is the most abundant environmental pollutant among polycyclic aromatic hydrocarbons (PAHs), and is widely distributed in air, water, soil, barbecue, and fried foods. Human beings are inevitably exposed to BaP. Studies have shown that

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

, 2005 目的探讨甲基汞对雄性大鼠生殖功能的影响和通过父系传播对后代的影响。方法将20只Wistar雄性大鼠随机分为4组,分别给予0、0.058、0.580、1.170mg/kg体重的氯化甲基汞,以隔日经口灌胃的方式染毒,持续染毒2个月后,将其与健康雌性大鼠交配,观察仔鼠的生长发育与神经行为发育情况。结果1.170、0.580mg/kg组仔鼠体重低于对照组,其早期生长发育指标落后于对照组仔鼠;染毒组仔鼠转体时间延长、前肢悬挂时间缩短,与对照组相比,差异有统计学意义 ...

Drivers of bat researchers’ intent to adopt field hygiene practices
Conservation Biology, EarlyView.Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Correlation Between Eating Disorders and Family Function of Female University Students in Beijing [PDF]
, 2009 目的考察北京女大学生进食障碍倾向与家庭功能的关系。方法采用进食障碍问卷(EDI)、家庭功能评定量表(FAD)测查北京两所大学共622名本科一年级女生。结果北京大一女生存在进食障碍倾向;生长在大城市的女生求瘦倾向得分明显高于生长在农村或中小城市的女生;体重关注者和非体重关注者相比,其家庭角色和情感介入两个功能更不健康。结论北京女大学生进食障碍倾向较为严重 ...

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, EarlyView.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

A Systematic Scoping Review of Self‐Regulated Learning With AI in Language Education
International Journal of Applied Linguistics, EarlyView.ABSTRACT The rapid development of artificial intelligence (AI) technology has brought new opportunities for second/foreign language (L2) education while also raising concerns about the use of AI tools. This systematic scoping review provides a snapshot of the current state of research situated at the intersection of self‐regulated learning (SRL) and AI

, 2007 蜜蜂群体由1只蜂王、几百只雄蜂和数千只工蜂组成,工蜂数量巨大,除蜂王和雄蜂共同完成生殖任务,巢内外活动均由工蜂完成,其行为呈现多样性。工蜂发育经过卵、幼虫、蛹、成虫4个阶段,其活动范围由温度、湿度相对稳定的巢内环境发展到复杂的巢外自然环境。随发育阶段和生活环境的变化,工蜂的生理、行为等方面也发生相应变化,这种变化为综合研究生物行为的分子机理提供了可能。又因工蜂数量多、体积较大易于观察、标记、饲养管理简单,而且目前对其形态、发育、生理、分子生物学、神经、社会生态等各方面的研究比较充分 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Although the use of AI technologies (e.g., chatbots and automated writing evaluations (AWE)) has gained considerable attention in language learning fields in recent years, how AI technologies have been designed and implemented in language learning education, as well as their effectiveness, is understudied.
