No‐Tillage Enhances Macroaggregate Stability and Carbon‐Nitrogen Storage but Drives Aggregate‐Size‐Dependent Phosphorus and Base Cation Distribution in Highly Weathered Tropical Soils of Central Africa

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT The dynamics of soil aggregate stability and the associated organic carbon and nutrient pools under contrasting tillage practices remain underexplored in the humid tropics of Central Africa, where rapid organic matter decomposition due to high temperatures and microbial activity challenges soil health.

Intercomparison of carbon‐13 and carbon‐14 tracer approaches for estimating marine calcification and net primary production

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...

Role of Si Alloying in the Microstructure Evolution and Corrosion Performance of ZnAlMg Coatings

open access: yesMaterials and Corrosion, EarlyView.
Si alloying refines the coating microstructure and enables formation of Mg2Si. When present at the surface, this phase is the strongest early source of Mg2+, providing short‐term protection, followed by dissolution of MgZn2 and Zn and formation of more stable corrosion products.

Two new rupicolous species of Tibouchina (Melastomataceae) from the Parque Nacional da Chapada dos Guimarães, Mato Grosso, Brazil

open access: yesNordic Journal of Botany, EarlyView.
Two new species of Melastomataceae, Tibouchina caducifolia and T. dispar, are described from the Parque Nacional da Chapada dos Guimarães (PNCG), Mato Grosso, Brazil. Both show characters typical of the Southern clade of Tibouchina, including stamens with villose filaments and villose pedoconnective appendages, suggesting that they likely belong to ...

Applications of nanocarrier‐delivered RNA interference in agricultural biological control (2009–2025)

open access: yesNew Plant Protection, EarlyView.
Despite 17 years of development, the effectiveness of nanocarrier‐delivered RNAi pesticide (NDRP) for agricultural biological control remains limited. The successful development of effective NDRP development requires the coordinated optimization of target gene selection and nanocarrier properties, including RNA dosage, multi‐gene targeting, protection ...

Remote sensing and citizen science for habitat mapping: A machine learning approach to lowland heathland in Surrey, UK

open access: yesPeople and Nature, EarlyView.
Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

Mechanical and Impact Response of Adhesively Bonded ASA/PA12 Sandwich Structures Produced by Fused Filament Fabrication

open access: yesPolymer Engineering &Science, EarlyView.
Adhesively bonded ASA/PA12 FFF sandwich structures reveal that interfacial compliance governs mechanical performance. Cyanoacrylate enhances strength but induces brittle failure, while polyurethane improves ductility and impact resistance, demonstrating that adhesive properties and stacking sequence are critical design parameters for optimizing multi ...

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Precision agriculture for water saving: The case of processing tomato and table grape

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Agriculture faces increasing pressure to produce high‐quality food while reducing water use under intensifying climate change and water scarcity. This study compared sensor‐based precision irrigation, drone monitoring, and near‐infrared spectroscopy with conventional farmer management in table grape and processing tomato production systems.
