Environmental DNA Metabarcoding Reveals the Variations in Fish Diversity Across the Yangtze River Basin and the Effects of the Three Gorges Dam

It is imperative that freshwater fish biodiversity research incorporates diverse components, encompassing taxonomy, phylogeny and function, alongside multifaceted facets, including richness, divergence and regularity. This comprehensive approach is essential to facilitate a more...

E3 Ubiquitin LigasePdSINA2D in Populus deltoides Positively Regulates ABA-Dependent StressTolerance through Ubiquitination of FREE1 in Poplar

Abstract Populus deltoides “Shalinyang” (PdS) displays reduced tolerance to abiotic stresses. SINA (seven in absentia) proteins, a subtype of E3 ubiquitin ligases, play crucial roles in regulating plant growth and responses to abiotic stresses. However, the characteristics and po...

Impact of ozone pollution on gross primary productivity during a large-scale emission reduction: Implications for strengthening carbon sink over megacity clusters in China

Ozone (O 3 ) pollution poses a significant threat to plant growth and diminishes ecosystem carbon sequestration capacity in China, representing a critical challenge to achieving “dual carbon” goals. A large-scale emission reduction that occurred during the Coronavirus disease 201...

Mannose Ameliorates Radiation-Induced Intestinal Injury in Mice via Preventing Mitochondrial Dysfunction

Aims: Radiation-induced intestinal injury (RIII) severely compromises the quality of life in patients undergoing abdominal/pelvic radiotherapy and may necessitate treatment discontinuation. To date, there is no approved agent for the prevention or treatment of RIII. This study ai...

Flocculation and Dewatering Mechanisms of Pyrite Flotation Tailings: Synergistic Roles of Polyferric Chloride, Polydiallyldimethylammonium Chloride, and Skeleton Builders on Microstructure Evolution

This study investigates the conditioning and deep dewatering of pyrite tailings slurry using a composite system comprising polyferric chloride (PFC), polydiallyldimethylammonium chloride (PDMDAAC), and fly ash as a skeleton builder. The synergistic application significantly enhan...
