Wheat straw incorporation enhances paddy soil quality: Evidence from a pot experiment

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Evaluating soil quality under various management practices in agroecosystems is crucial for understanding soil functioning. In this study, a soil quality index (SQI) was developed to assess the impact of wheat straw incorporation on soil quality.

Nutritionally Responsive PMv DAT Neurons Are Dynamically Regulated During Pubertal Transition

The FASEB Journal, Volume 39, Issue 13, 15 July 2025.
The ventral premammillary nucleus of the hypothalamus plays an essential role in the metabolic control of reproduction. Puberty brings large changes to a subpopulation of PMvLepRb cells expressing the dopamine transporter (PMvDAT). DAT gene expression is higher in prepubertal females than in adults and is regulated by leptin in prepubertal females ...

Floodplain land use gradients have a stronger effect on soil microbial enzyme activity than spatiotemporal variability

Ecosphere, Volume 16, Issue 7, July 2025.
Abstract Climate change is leading to flood events with higher frequency and longer duration. Changes in seasonal flooding that affect water saturation of soils can impact soil microbial extracellular enzyme activity (EEA) that mediates nutrient and carbon cycling.
