Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1143-1160, April 2026.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that

International Journal of Applied Linguistics, Volume 36, Issue 1, Page 522-539, February 2026.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

Integrative Conservation, Volume 4, Issue 4, Page 569-583, December 2025.Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...

The Genome of Phoebe zhennan (Lauraceae) and Comparative Genomics of Phoebe 楠木(樟科)基因组与楠属植物比较基因组学研究
Integrative Conservation, Volume 4, Issue 4, Page 584-599, December 2025.Phoebe zhennan is a Chinese endemic and valuable timber species of Phoebe (Lauraceae). We present a chromosome‐level genome assembly of P. zhennan. Our research provides novel insights into the genome evolution of Phoebe, including whole‐genome duplication, phylogenetic relationships of magnoliids, and key MYB regulatory genes involved in lignin ...

A new beef: An analysis of discourse coalitions in the nascent cellular agriculture policy subsystem
Review of Policy Research, Volume 42, Issue 6, Page 1404-1427, November 2025.Abstract A robust approach to examining the nature and influence of coalitions in the policy process is the Advocacy Coalition Framework (ACF), which is especially useful to study policy issues fraught with scientific and technical controversy. Yet, important gaps exist in ACF literature regarding nascent policy subsystems. Consequently, there is scant

Functional Study of Ecdysone Signaling Pathway Related Genes During Ovarian Maturation and Juvenile Development of The Mud Crab, Scylla paramamosain [PDF]
, 2015 蜕皮激素在节肢动物蜕皮、附肢再生以及繁殖等生理过程起着重要作用。蜕皮激素受体（Ecdysonereceptor，EcR）在整个蜕皮激素信号通路中起重要作用。当蜕皮激素合成达到一定浓度以后，能够诱导EcR与维甲酸X受体（retinoidXreceptor，RXR）形成有功能的EcR/RXR异源二聚体，进而启动蜕皮激素信号通路产生级联反应，诱导E75、E74、BroadComplex（BR-C）等早期应答基因的转录。这些早期应答基因进一步调控下游一些蛋白酶和其它基因的陆续表达，产生次级应答 ...

, 2010 采用生物信息学方法首次对非洲爪蟾短型肽聚糖识别蛋白(xePGRP-S)基因进行了克隆,并对其在胚胎发育和成年爪蟾各组织中的表达状况进行了分析。xePGRP-ScDNA全长720bp,开放阅读框为549bp,编码182个氨基酸。序列比对显示xePGRP-S与其他物种PGRP-S的序列相似性在42.4%—50.5%之间。RT-PCR显示在非洲爪蟾胚胎发育至3d时可以明显检测到xePGRP-S的表达,之后呈持续性表达,且在所检测的心、肝、脾、肺、肾 ...

Integrative Conservation, Volume 4, Issue 3, Page 405-415, September 2025.Assessing the genetic diversity of edible insects harvested from the wild is a pre‐requisite for designing conservation and management policies. The caterpillars of Gynanisa maja (Saturniidae) are harvested in large numbers in mopane woodlands in southern Africa, where they represent a seasonal source of income and nutrition to many rural communities ...
