Savanna soil carbon accrual occurs through particulate organic matter from grass rather than tree biomass, regardless of atmospheric CO2 levels

Functional Ecology, Volume 40, Issue 8, Page 2532-2547, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Afforestation schemes in savannas are increasingly promoted as a carbon storage strategy despite threats to biodiversity. We also lack a clear understanding of how trees and grasses differentially contribute to the major carbon store in savannas, that is, soil organic ...

Nanopore Long‐Read Metagenomics Reveals Pollution‐Driven Antibiotic Resistance and Xenobiotic Degradation in Urban Beach Microbiomes

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Using nanopore metagenomics, this study reveals that anthropogenic pollution drives ecological and functional shifts in coastal microbiomes. Pristine island environments act as stable, Prochlorococcus‐dominated baselines, whereas urban beaches function as hotspots for opportunistic taxa, harbouring a robust genomic potential for xenobiotic degradation ...

The multifaceted regulatory network of microRNA396: Orchestrating plant plasticity through coordinating development and various stresses

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 3073-3085, August 2026.
This review examines the character and function of the microRNA miR396, which helps plants balance growth, reproduction, regeneration, and survival under various stresses, highlighting recent progress and evidence that this pathway shapes crop yield, pest and disease resistance, and tissue regeneration, making it a promising target for precision crop ...

Soil phosphorus drives subcontinental patterns of carbon isotope discrimination across Australia

New Phytologist, Volume 251, Issue 3, Page 1038-1053, August 2026.
Summary Several transects have been established to study the sensitivity of carbon isotope discrimination (Δ13C) in woody plants to mean annual precipitation (MAP) across Australia. These have shown a surprising divergence in Δ13C‐MAP sensitivity among subcontinental regions.

Pollen longevity and viability dataset: an integrated resource for plant research and conservation

New Phytologist, Volume 251, Issue 4, Page 1631-1639, August 2026.
The most common methods to estimate pollen viability. Summary Pollen viability and longevity are key traits in plant reproduction, with implications for gene flow, crop breeding, and ex situ plant conservation. However, published data on these traits remain dispersed across disciplines, languages, and methods, limiting their accessibility and reuse ...
