Field assessment of nitrogen sources in Brassica carinata using physiological indicators of nitrogen status under temperate no‐till conditions

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Improving nitrogen (N) use efficiency in Brassica carinata is essential to sustain yield and lower biofuel carbon intensity under variable field conditions. We hypothesized that integrating physiological indicators, such as the nitrogen nutrition index (NNI) and the critical nitrogen uptake curve (CriNUC), into N management frameworks would ...

Species functional traits affect regional and local dominance across western Amazonian forests

Journal of Ecology, Volume 114, Issue 1, January 2026.
Dominant tree species in western Amazonian forests show distinct functional trait combinations linked to habitat type: conservative traits in stressful habitats and greater plant size in less stressful environments. Local dominants are defined by resource conservation strategies and widespread dominants are defined by resource acquisition strategies. A

The Impact of Sustainable Nitrogen Management on the Health Risks of Unsafe Drinking Water and the Mediating Role of Food Production

Review of Policy Research, Volume 42, Issue 6, Page 1496-1508, November 2025.
ABSTRACT This study adopts a policy‐centric perspective to explore the complex relationship between sustainable nitrogen management (SNM) and the health risks associated with unsafe drinking water. The critical policy challenge lies in balancing the essential role of nitrogen fertilizers in achieving high agricultural productivity with their ...

Increasingly conservative N cycling in a wet tropical forest: Litter and stream N concentrations decline over 29 years despite surges from hurricanes

Journal of Ecology, Volume 113, Issue 9, Page 2476-2496, September 2025.
Conceptual model integrating short‐ and long‐term responses of N in litterfall and stream water in a wet tropical forest subject to hurricanes. Despite N surges following hurricanes, N cycling becomes more conservative in the absence of frequent hurricanes.
