Effects of nitrogen deposition on territory numbers of breeding birds. [PDF]

Conserv Biol
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 ...

Strong scale-dependent relationships between fine-root function and soil properties uncovered with spatially coupled sampling. [PDF]

New Phytol
Summary Substantial fine‐root trait variation is found at fine spatial scales but rarely linked to edaphic variation. We assessed the spatial scales of variation in fine‐root traits and adjacent soils using a spatially coupled, nested sampling scheme along a fertility gradient in a seasonally dry tropical forest tree, Handroanthus ochraceus.

Chromosomal Inversion Associated With Diet Differences in Common Quails Sharing Wintering Grounds. [PDF]

Ecol Evol
A large chromosomal inversion in common quails (Coturnix coturnix) is associated with phenotypic traits. In a wintering population in southern Spain, we found all three karyotypes coexisting but showing differences in migratory behavior and diet, as exemplified by the isotopic signature.

Compost legacy effects in active roadside restoration: Medium‐term shifts in plant succession

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Roadside restoration experiment established on volcanic tephra following road construction in Andean Patagonia. A single application of municipal (MC) or biosolids (BC) compost rapidly increased plant cover compared with untreated controls (C) but led to distinct, exotic‐dominated plant communities over 6 years.

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 ...

ASOCIACIÓN DE ESPECIES LEÑOSAS EN BANCOS DE FORRAJE: INFLUENCIA SOBRE EL APORTE DE HOJARASCA, DESCOMPOSICIÓN Y LIBERACIÓN DE NITRÓGENO

Tropical and Subtropical Agroecosystems, 2012
Se evaluó el aporte de hojarasca, descomposición y liberación de N del follaje de tres especies leñosas, Leucaena leucocephala, Guazuma ulmifolia y Moringa oleifera, en bancos de forraje puros y la asociación de L. leucocephala + G. ulmifolia y L. leucocephala + M. oleifera, como bancos de forraje mixto.

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.
