Population genetic variation and symbiotic and associated bacteria diversity studies of bryozoan Bugula neritina based on high-throughput sequencing [PDF]
, 2016 多室草苔虫是一种重要的药源生物，从这种生物体内提取出的多种草苔虫内酯被证明有着较强的抗癌活性，其中草苔虫内酯bryostatin1是治疗阿尔茨海默症和多种癌症的最有希望的药物来源，而草苔虫内酯bryostatin1的产生与多室草苔虫体内的共生细菌“CandidatusEndobugulasertula”密切相关。然而，国内学者从中国沿海的多室草苔虫中却一直未能成功提取出这种最具药用价值的草苔虫内酯bryostatin1 ...

Investigating the Origin of Topological‐Hall‐Like Resistivity in Zn‐Doped Mn2Sb Ferrimagnet
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Skyrmions and other chiral spin textures have been extensively studied as potential building blocks for novel spintronic devices. Hall‐resistivity anomalies that deviate from magnetization scaling, known as the topological Hall effect, have been widely employed as evidence for the presence of chiral spin textures in magnetic materials. However,

Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.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.

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

Conservation 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.
