Soybean yield performance in oxisols with varying morphological and physicochemical characteristics

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Soybean (Glycine max (L.) Merril) yield in tropical high‐altitude regions is strongly influenced by soil physical and chemical attributes, particularly in highly weathered oxisols, where variability among suborders may affect crop performance.

Realistic species loss has little effect on local resource depletion and competitive pressure in a temperate wet meadow

Journal of Ecology, Volume 114, Issue 5, May 2026.
Realistic biodiversity loss in a species‐rich wet meadow had limited effects on community competitive ability. Phytometers revealed strong competition compared to competition‐free gaps, but similar pressure across richness levels (1–27 species). Resource depletion poorly explained responses, highlighting that dominance, seasonal dynamics and biotic ...

Macro- and micronutrients availability in a cropped soil in Mabegondo (A Coruña) [PDF]

, 2001
] The Mehlich–3 extraction reagent recommended for use on a wide range of acid soil types was utilised for extracting in a simple step, both major elements (P, Ca, Mg) and micronutrients (Fe, Mn, Cu and Zn,). The study area was an elementary agricultural

Integrated 2D–3D Proteomic Profiling Identifies MLK4 as a Microenvironment‐Responsive Regulator of Chemotherapeutic Resistance in Human Glioblastoma Cells

Biology of the Cell, Volume 118, Issue 5, May 2026.
Glioblastoma U251MG cells were cultured in 2D monolayers and 3D spheroids to model tumor architecture. Comparative LC–MS/MS proteomics identified proteins associated with chemoresistance in 3D conditions. Selected candidates were functionally validated by gene knockdown and drug sensitivity assays to confirm their roles in modulating glioblastoma ...

Nutrition Status of Trees on Spoil Heaps After Coal Mining Can Be Inferred From Seasonal Dynamics of Foliar Nutrient Concentrations

Land Degradation &Development, Volume 37, Issue 7, Page 2583-2596, 30 April 2026.
ABSTRACT A stable vegetation cover on given habitat conditions can be one of the possible requirements for post‐mining sites, as it can prevent erosion and dustiness of these anthropogenic surfaces and bring several practical future benefits, such as biomass production and microclimate improvement.
