Taxonomic and functional diversity of urban bees of the world
Conservation 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 ...

Dianci bileiqi, 2020 提出一种基于三参数Burr分布的估计方法来描述零值悬瓷绝缘子的温度分布特性。为验证这一方法,以某省电网运行10年及以上变电站悬式绝缘子红外测零项目的红外测温数据为研究对象,通过统计分析建立了三参数Burr分布数学模型。由于该分布函数的参数在极大似然估计法下没有显式解,故采用牛顿法对其求解,可得到三参数Burr分布对绝缘子零值温差分布的拟合曲线;然后,在MATLAB中利用Kolmogorov-Smirnov方法对于该分布模型进行了参数检验。检验结果表明 ...

Emerging applications of large language models in ecology and conservation science
Conservation Biology, EarlyView.Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Conservation Biology, EarlyView.Abstract Reversing ongoing biodiversity loss requires effectively managing anthropogenic threats. Although conservation actions can mitigate these threats, prioritizing and targeting such actions remain challenging because species respond differently depending on the nature of the threats and their biological traits.

OnomázeinAlthough å§å§ /jiejie/ (“elder sister”) and 妹妹 /meimei/ (“younger sister”) are basic relatives' terms of the nuclear and consanguinity kinship, they mean a big challenge when they are translated into Spanish because of the linguistic and cultural differences and defaults between the Chinese and the Spanish.

Conservation Biology, EarlyView.Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

Subspecies taxonomy reflects social and geographic patterns of taxonomic effort in tetrapods
Conservation Biology, EarlyView.Abstract Subspecies have been used in conservation biology to account for intraspecific patterns in genetic diversity, which is crucial to long‐term population viability. Although over 3200 subspecies are currently assessed by the International Union for Conservation of Nature Red List, their biological relevance remains controversial.

Dianci bileiqi, 1980 本文研究了具有内部微观结构缺陷的瓷件在单轴向应力状态下强度的维布尔分布,给出δu=0情况下决定维布尔参数的一个图解方法。根据维布尔分布导出抗折瓷件在一定可靠性下极限应力下限值的计算公式,并比较了按维布尔分布和按正态分布计算的在相同可靠性下瓷件极限应力下限值的结果,结果表明按维布尔分布计算的下限位偏于安全。

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
