Emerging applications of large language models in ecology and conservation science
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

Physiological responses of three cultivar seedlings of Bougainvillea under drought stress [PDF]
该研究对勤花三角梅(Bougainvillea buttiana Miss Manila')、樱花三角梅(B.glabra Imperial; Delight')和金心鸳鸯三角梅(B.peruviana; Thimma')三个三角梅品种的幼苗进行人工干旱胁迫,分析了干旱胁迫对三角梅品种的外观形态和生理生化水平的影响,探讨了不同品种三角梅对干旱胁迫的; 适应能力。结果表明:随着干旱时间的延长,三角梅品种的叶片出现下垂、皱缩、变黄、脱落,最后植株死亡;过氧化物酶POD活性先升高后降低,而超氧化物歧 ...

ABSTRACT This study investigates how ordinary Taiwanese netizens perform linguistic authority by policing others’ use of Mainland Chinese expressions in everyday online interactions not originally intended to be political and how such policing is subsequently supported, resisted, or (de)legitimized in the context of Taiwan–China relations.

为探讨工程堆积体不同植被类型的枯落物特征、枯落物持水及拦蓄能力、土壤物理性状和土壤涵水性能,采用室内浸水法和环刀法分别对工程堆积体植被与原生植被的枯落物及0—20 cm土层的持水能力进行研究。结果表明:(1)不同植被类型枯落物厚度及蓄积量均存在显著差异(P灌木林>乔木林。(3)各植被类型土壤最大持水量及毛管持水量均存在显著差异(P灌木林>乔木林。从堆积体枯落物和土壤持水能力角度来看,草灌混交这一搭配模式可以作为工程堆积体的先锋植被,用于在堆积体初期构建稳定群落生态结构 ...
