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

Effects of nitrogen deposition on territory numbers of breeding birds
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Deposition of atmospheric N (nitrogen) is assumed to be a major cause of biodiversity decline in Europe. To date, few studies on the direct or indirect effects of N on bird species have been conducted. Using Swiss bird count data and habitat data, we analyzed the correlation of N deposition with numbers of territories of 112 breeding bird ...

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 ...

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.

IMPACTO DEL PETRÓLEO CRUDO EN SUELO SOBRE LA MICROBIOTA DE VIDA LIBRE FIJADORA DE NITRÓGENO
Tropical and Subtropical Agroecosystems, 2011 Los derrames de petróleo afectan las propiedades fÃsicas del suelo y especialmente las poblaciones naturales de microorganismos. En particular causan disminución en bacterias fijadoras de nitrógeno de vida libre, encargadas de asimilar y reciclar nutrientes en los ciclos biogeoquÃmicos; al alterarse éstos, se afecta la fertilidad del suelo.
