微藻油脂合成的转录调控研究进展Advances in transcriptional regulation of lipid synthesis in microalgae
Zhongguo youzhi生物燃料是传统化石燃料的理想替代品，微藻是生产生物燃料的优良原料,通过对微藻油脂合成和调控的了解，能够有效提高微藻生产生物柴油的效率。转录因子是一种具有特殊功能结构、行使调控基因表达功能的蛋白质分子，在复杂的油脂合成代谢过程中，转录因子能对代谢过程中多个酶系进行集体调控，从而促进藻细胞中油脂积累。从微藻油脂的合成途径出发，简要介绍了合成途径中的关键酶，重点综述了bZIP、MYB、Dof、bHLH转录因子对于微藻油脂合成的调控影响。微藻油脂合成涉及多个亚细胞单位的多条途径，是一个十分复杂的代谢网络过程 ...

Integrative Conservation, EarlyView.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,

Integrative Conservation, EarlyView.We found the estimated use of tiger bone glue within the last 12 months to be 6.9%. We found a stated motivation of taking TBG to improve health, and by the suggestion of one's social group. We suggest reducing the acceptability of TBG as medicine and encouraging non‐animal‐based medicinal alternatives.

Integrative Conservation, EarlyView.Our research allows us to understand the predictors of extinction risk in traditional Chinese medicinal (TCM) plant species with known threat status, and incorporate this knowledge to predict other TCM plants with unknown conservation status in China so as to improve the overall effectiveness of conservation strategies.

Wildlife Letters, EarlyView.Eimeria saudiensis represents a genus of apicomplexan parasites capable of inducing coccidiosis in Arabian oryx. Our research concentrated on the morphological and molecular investigation of Eimeria spp. in the captive oryx herd in Oman. The therapeutic and management practices employed at the Mammals Breeding Center were reassessed to diminish ...

Wildlife Letters, EarlyView.Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Analysis on the reliability of reanalysis surface flux datasets for China(我国范围内多个再分析地表通量数据集的可信度分析)
Zhejiang Daxue xuebao. Lixue ban, 2006 利用NCEP/NCAR (NCEP1)、NCEP/DOE(NCEP2)及ECMWF的再分析地表通量（感热和潜热通量）资料，以及由经验公式计算得出的我国地表通量的气候值（以下简称气候值），采用可视化分析、统计分析和天气气候学诊断方法，分析了三组再分析数据集的地表感热、潜热通量，以及基于地表热通量的鲍文比和地表热源在不同季节的空间分布和年变化，并与气候值做了比较.结果显示，尽管存在一些共同的问题（如三组再分析数据集潜热通量的值明显偏大），但不同再分析地表通量所反映的我国不同季节地表感 ...

Strangers on the ladder of the party‐state: Women in teaching in Nationalist Taiwan, 1940s–1980s
Gender &History, EarlyView.Abstract As the ruling party of a party‐state in China and Taiwan, the Nationalist Party (Kuomintang/Guomindang) built a close relationship with the teaching profession. Many teachers joined the party and there was a well‐trodden pathway from teaching into local representative politics and civil service.

粪便显微分析和DNA宏条形码技术在野猪食性分析中的应用和比较
野生动物学报, 2022 有蹄类动物食性分析对基础生态学研究乃至大型濒危食肉动物保护与恢复有重要科学价值。食物组成定量化有很多方法,常用的方法有粪便显微分析和DNA宏条形码技术,但各有其优缺点。2014年12月—2016年3月,在珲春、汪清、黄泥河、天桥岭和穆棱5个地区收集了野猪(Sus scrofa)新鲜粪便样品,运用粪便显微分析和DNA宏条形码技术比较研究了冬季野猪食性。仅对比分析了野猪植物性食物,通过粪便显微分析获得的野猪食物组成包含32属植物,比例大于4%的主要食物有木贼属(Equisetum,(22.76±1.87)%)
