Se pu = Chinese journal of chromatography, 2021 食品中残留的痕量有毒物质严重威胁人体健康,对其进行分析十分必要。然而,食品中有毒物质种类多、量少、基质复杂,需选择适当的样品预处理技术进行提取和净化。磁固相萃取(MSPE)因具有操作简单、省时快速、无需离心过滤、环境友好等优点,被认为是一种高效的样品预处理技术并应用于食品分析中。MSPE中使用的磁性吸附剂的吸附容量和选择性是影响MSPE萃取效率和选择性高低的关键,对所建立分析方法的准确度起着关键作用。碳基磁性材料是具有价格低廉、来源丰富、比表面积大、化学稳定性好、吸附容量高 ...

Wildlife Letters, EarlyView.Using a 3‐year, broad‐scale camera‐trap network in western Kansas, we tested whether coyotes and American badgers exhibit spatiotemporal patterns consistent with coordinated hunting. Despite high diel activity overlap, detection‐conditioned co‐detections occurred far less frequently than expected under independence, and short‐term temporal sequencing ...

Wildlife 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.

Wildlife Letters, EarlyView.Although once abundant across its range, gray foxes (Urocyon cinereoargenteus) are purportedly declining. While range maps indicate that gray fox potentially occur throughout the central United States, contemporary distribution maps are needed. We developed a Habitat Suitability Model for six states, leveraging gray fox presence data in an ensemble ...

Methods in Ecology and Evolution, EarlyView.Abstract Molecular identification of insect food webs can accurately reveal complex trophic interactions and serve as a foundation for understanding ecosystem functioning and advancing biodiversity conservation. This process typically involves DNA library construction, high‐throughput sequencing and subsequent steps, including data assembly, annotation,

Using incentive payments to promote human–carnivore coexistence
Conservation Biology, EarlyView.Abstract For many large carnivores, minimizing the financial burden they impose on local people is critical to their conservation. Incentive‐based programs that provide people with financial benefits for taking pro‐conservation actions or achieving conservation goals are a promising tool for promoting human–carnivore coexistence. Although the number of

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 ...

, 2012 动物园人工湖作为一种特殊的湿地,良好的环境设置和科学的管理对生活在其中的鸟类健康和繁殖有着直接的影响。放养鸟类与野生鸟类之间、放养鸟类之间、鸟类与人之间、鸟类与环境之间存在互相干扰,需要综合考虑鸟类的自然栖息地特征和食性以控制放养乌的种类和数量;为鸟类设置合适的隐蔽场所,提供合适的巢材巢穴,多点分散投喂食物等措施有助于减少干扰的发生;参考家鹅生态化养殖法,有意识地种植某些植物或投放鲜活食物既为鸟类提供了自由采食的食物来源,又很好地展示了鸟类的自然采食行为;改变在岛上投喂食物的方式 ...

Integrative Conservation, Volume 5, Issue 1, Page 125-136, March 2026.We collated detections of the sun bear from new and previously published camera trap studies across its range. We then analysed these detections at two different spatial scales to assess the habitat associations and diel activity of this species. We found that the sun bear is tolerant to moderate habitat disturbances. ABSTRACT Degraded tropical forests,

丰容对白臀叶猴(Pygathrix nemaeus)的采食量及行为影响
野生动物学报, 2017 对南宁市动物园的3只白臀叶猴(Pygathrix nemaeus)进行笼舍环境丰容和食物丰容,采用瞬时取样和焦点取样法相结合的方式,探讨丰容前后动物的采食量和各种行为变化。研究表明,环境丰容对白臀叶猴行为的影响明显,其中积极行为的时间增加,刻板行为、异常行为显著降低,而独笼圈养的雄性白臀叶猴的一般行为变化不明显,其余2只白臀叶猴的一般行为均增加。食物丰容仅促进了白臀叶猴在采食时增加了探究行为和其他积极行为,对每天的采食量无影响。
