Influence of Enhanced Rock Weathering of Nepheline‐Syenite Tailings on Major and Trace Elements Accumulation in Wheat

European Journal of Soil Science, Volume 77, Issue 1, January–February 2026.
Enhanced weathering of silicates consumes atmospheric CO2 and releases bio‐essential ions and trace elements that enrich the rhizosphere. This increases availability and uptake, influencing plant nutrient status and growth. ABSTRACT Soil nutrient depletion and quality are critical challenges facing agriculture and have been exacerbated by the long‐term

Strong Variation in Land‐Use Change Impacts on Tropical Avian Phylogenetic Diversity Between Ecoregions Highlights the Need to Sample Large Spatial Scales

Global Change Biology, Volume 32, Issue 1, January 2026.
Forest conversion for agriculture is a major cause of biodiversity loss in the tropics, but its impacts depend on how broadly they are measured. Using data from across Colombia, one of the most biodiverse countries in the world, we examined how deforestation for cattle farming affects the evolutionary history of bird species.

Individuality obscures geographical song variation in two passerine sister species with contrasting distributions and movement ecology

Ibis, Volume 168, Issue 1, Page 95-116, January 2026.
Songbirds are a well‐established model group for the study of cultural evolution as their songs are learned (i.e. culturally transmitted), which may lead to divergence in song characteristics between populations. Song variation across populations may be affected by geographical isolation, timing and duration of the learning period, and life strategies ...

Understanding the Biogeographic Scope of Next‐Generation Sequencing Methods in Genomic Studies of Montane Taxa

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Next‐generation sequencing has become a powerful tool for increasing the robustness and reliability of phylogeographic analyses. However, it is unclear how much the use of these techniques has grown quantitatively, and to what extent their use has been equitably distributed among regions.

Dark matter as a dynamic effect due to a non-minimal gravitational coupling with matter

, 2010
In this work the phenomenology of models possessing a non-minimal coupling between matter and geometry is discussed, with a particular focus on the possibility of describing the flattening of the galactic rotation curves as a dynamically generated effect
