Long‐Term Effects of Biochar Addition on Diameter Growth in Young Established Boreal Scots Pine Stands

open access: yesGCB Bioenergy, Volume 18, Issue 10, October 2026.
Biochar application on top of the soil can be successful in already established and naturally regenerated boreal forest stands. Biochar tends to increase diameter and basal area growth. Increasing biochar dose enhanced growth response. Biochar induced growth response diminished 5 years after application.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

open access: yesJournal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Ectomycorrhizal Cortinariaceae species dominate class II peroxidase gene expression in a boreal forest soil

open access: yesNew Phytologist, Volume 252, Issue 1, Page 400-413, October 2026.
Share of transcripts and ITS2 sequence for each gene families among identified fungal contigs and OTUs. Summary Boreal forest ecosystems constitute a large terrestrial reservoir of carbon. In these nitrogen‐limited environments, release of nutrients through decomposition of soil organic matter is of fundamental importance.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

open access: yesPlant, Cell &Environment, Volume 49, Issue 10, Page 7676-7691, October 2026.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin

open access: yesSedimentology, Volume 73, Issue 6, Page 2454-2487, October 2026.
ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.
