In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

不同内膜准备方案在子宫内膜异位症患者冻融囊胚移植中的疗效观察 [PDF]
, 2019 目的研究不同内膜准备方案对子宫内膜异位症(EMs)患者囊胚冻融移植(FET)妊娠结局的影响。方法回顾性分析EMs患者375个囊胚FET周期,按照子宫内膜准备方式分为:单纯人工周期组(HRT组,45个周期),促性腺激素释放激素激动剂降调节后人工周期组(GnRH-a+HRT组,121个周期)和自然周期组(NC组,209个周期)。比较3种内膜准备方案的囊胚FET妊娠结局。结果 3组EMs患者间年龄、不孕年限、基础抗苗勒管激素(AMH)和基础内分泌水平比较均无统计学差异(P>0.05 ...

Informing spatial conservation prioritization with species’ traits
Conservation Biology, EarlyView.Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.

不同受精方式对第六天囊胚解冻移植周期妊娠结局的影响 [PDF]
, 2023 目的比较常规体外受精（IVF）和卵胞质内单精子注射（ICSI）两种不同授精方式对解冻移植第六天（D6）囊胚患者妊娠结局的影响。方法回顾性队列研究分析中山大学附属第三医院生殖中心2018年1月至2020年4月期间解冻移植第六天囊胚移植患者的临床资料，按受精方式分为常规IVF组（446例）和ICSI受精组（200例）。按是否有第五天（D5）囊胚移植史，分为仅有D6囊胚冷冻及移植的患者，以及有D5囊胚移植史的患者。比较两组患者基本资料、囊胚质量及妊娠结局。结果IVF组和ICSI组患者BMI，不孕年限 ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, EarlyView.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

High nitrogen enrichment buffers plant photosynthesis against herbivory damage
Functional Ecology, Volume 40, Issue 1, Page 229-238, January 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivorous insects and nitrogen deposition are key drivers of ecosystem productivity under global change. However, their combined effects on plant photosynthesis, particularly during insect outbreaks, remain poorly understood in natural ecosystems.

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 ...
