Predictive performance of Fetal Medicine Foundation first‐trimester screening algorithm for pre‐eclampsia according to conception mode

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 6, Page 806-814, June 2026.
ABSTRACT Objective To investigate the incidence of pre‐eclampsia (PE) and the predictive performance of the Fetal Medicine Foundation (FMF) first‐trimester PE screening algorithm across pregnancies conceived using assisted reproductive technology (ART), after ovulation induction (OI) and through spontaneous conception (SC).

Rapid construction of insect–plant interaction networks via multiplexed long‐fragment DNA metabarcoding and NGS

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 6, Page 1896-1909, June 2026.
Abstract Molecular identification of insect food webs can accurately reveal complex trophic interactions and serve as a foundation for understanding ecosystem functioning and advancing biodiversity conservation. This process typically involves DNA library construction, high‐throughput sequencing and subsequent steps, including data assembly, annotation,

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Narrative formatting, chronotopic orderings, and moralization in ex‐gay stories

open access: yesJournal of Linguistic Anthropology, Volume 36, Issue 1, May 2026.
Abstract Formatted stories rely on spatiotemporal cues to evoke recognizability through linearity, which prescribes a particular template for meaning‐making. This article examines stories narrated by ex‐gay members of a Christian organization in Singapore and considers how chronotopes within the stories are ordered to regiment ways of feeling for ...

麝鼠仔鼠的性别鉴定

open access: yes野生动物学报, 1988
有关成龄和幼龄麝鼠性别鉴定的报道屡见不鲜(华树芳,1985,刘桂仁,1984;曲增文,1987,李晓坤,1987),其方法大同小异,我们亦采用其中的“看”和“触摸”法对成龄和幼龄麝鼠进行性别鉴定。但就仔鼠的性别鉴定至今尚未见报道。如能对仔鼠进行性别鉴定,对科研及生产会有重要意义。笔者通过1986 ...

Cu‐Based Catalysts Design Toward Electrochemical CO2 Reduction to Valuable Multi‐Carbons Products

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Electrochemical reduction of CO2 to multi‐carbon products (e.g., C2+, ethene, ethanol, etc.) not only effectively decreases the CO2 concentration in atmosphere but also shows great potential economic benefits due to these exploitable value‐added products. The Cu‐based catalysts have caught much attention in CO2 electroreduction due to the good

犀牛角仿冒品研究现状

open access: yes野生动物学报, 2021
本研究总结了犀牛角仿冒品的研究现状。当前犀牛角的仿冒品主要包括以下几类:洞角、蹄匣、纤维聚合物、真假结合仿品和古犀角等。在这些仿冒品中,洞角的组织特征与犀牛角差别较大,鉴别二者相对容易;蹄匣、纤维聚合物、真假结合仿品和古犀角等特征与犀牛角存在很大的相似性,鉴定时存在一定难度。本研究分别指出了仿冒品与真犀牛角之间的差异或应采取的鉴定方法,将对从事犀牛角鉴定的工作人员提供一些参考。

Multi‐barcoding‐based species identification using a hierarchical attention network with staged curriculum learning

open access: yesMethods 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

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.
