Annual variations of biotic integrity in the upper Yangtze River using an adapted index of biotic integrity (IBI)

open access: yes, 2008
Adaptive modification and use of Karr's index of biotic integrity (IBI) for the upper Yangtze River, including 12 metrics in five categories, have typically occurred in line with the data collected by 6-year commercial fisheries investigation.

Continental scale metagenomics reveals Microcystis‐induced synchrony among aquatic taxa is exacerbated by trophic cascades

open access: yesEcography, EarlyView.
Harmful Microcystis proliferation severely threatens aquatic ecosystems globally, but its impacts on food‐web stability remain poorly understood. Here, we analyzed 1309 metagenomic samples from freshwater ecosystems across China to investigate how Microcystis abundance affects synchrony among taxa in multi‐trophic food webs (from bacteriophages to ...

Transcriptome Analysis Elucidates the Potential Key Genes Involved in Rib Development in bmp6-Deficient Silver Carp (Hypophthalmichthys molitrix)

open access: yesAnimals
Bone morphogenetic protein 6 (BMP-6) is a constituent of the TGF-β superfamily, known for its ability to stimulate bone and cartilage formation. The investigation of bmp6’s involvement in the formation of intermuscular bones in fish has garnered ...

Integrated Solvent‐Catalyst‐Dopant Strategy via Acidic DES for Synthesizing Lignin‐Derived Carbon Dots With High‐Quantum Yield to Achieve Efficient Photocatalytic Degradation of Tetracycline

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A deep eutectic solvent (ChCl/pTSA) platform enables integrated solvent, catalyst, and dopant functions, producing sulfur‐doped carbon quantum dots with a high sp2‐C content (82.8%) and a quantum yield of 56.9%. When combined with TiO2, the CQDs form TiOC and TiOS interfacial bridges, achieving 97.3% tetracycline photodegradation with excellent ...

Genome-wide identification of heat shock factors in Myricaria laxiflora and their response to abiotic stresses

open access: yesBMC Genomics
Myricaria laxiflora is a rare and endangered shrub in China, and its wild populations are threatened by diverse abiotic stresses. Heat shock factors (HSFs) are essential for coping with environmental stresses, however, information about HSFs in M ...

Electron‐Rich Para‐Methylpyridine‐Functionalized TEMPO Empowers Long‐Lived Neutral Aqueous Organic Redox Flow Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Three methylpyridine‐functionalized TEMPOs were synthesized through an electron‐rich regulation strategy. The calculation of transition states supported the highest reaction efficiency of para‐MePy‐TEMPOs, which outperformed its analogues to have the best performance of AORFBs, opening a new avenue for exploring TEMPO‐based catholytes.
