A systematic review of avian influenza virus transmission models: Gaps and opportunities
Methods in Ecology and Evolution, EarlyView.Abstract Highly pathogenic avian influenza virus (HPAIV) increasingly threatens wild birds, poultry, non‐human mammals and humans, yet gaps and opportunities in avian influenza virus (AIV) transmission modelling have not been comprehensively synthesized.

Dianci bileiqi, 1985 通过对氧化锌电阻片承受短时过电压作用时的电气特性、能量吸收能力特性的研究,对氧化锌电阻片耐受短时过电压能力的评定方法提出讨论。对用变压器进行氧化锌电阻片短时过电压耐受能力试验出现残压波形畸变时,提出用等能量进行耐受时间等价性处理的办法。

Jianzhu Gangjiegou Jinzhan, 2023 采用带锚筋的锚板、腹板、端板以及加劲板作为连接件，可实现相邻上下层预制混凝土墙板之间的干式连接。为研究该新型全装配式剪力墙的受力性能和抗震性能，进行了2个剪跨比为1.916的试件和1个相同剪跨比和配筋率的现浇整体墙体的低周往复拟静力试验，分析了该全装配式剪力墙的承载能力、耗能能力、延性、位移角、耗能效率、刚度退化等性能。研究结果表明：现浇整体墙体和全装配式剪力墙的破坏形式均为受弯破坏，全装配式剪力墙的耗能能力、延性、位移角、耗能效率、刚度退化等抗震性能指标与现浇整体墙体基本接近，但承载力有所提高 ...

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

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon
Conservation Biology, EarlyView.Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

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.
