Wet Season Carbon (δ13C) and Nitrogen (δ15N) Composition of Modern Plants as Isotopic Framework for Agropastoral and Palaeoecological Studies in Northern Greece

open access: yesArchaeometry, Volume 68, Issue S2, Page S150-S160, May 2026.
ABSTRACT Mediterranean wetlands are one of Europe's most vital and endangered biodiversity hotspots. This study determined the carbon (δ13C) and nitrogen (δ15N) isotope values of modern plants to construct an isotopic framework by which to contextualize agropastoral management in and around past wetland ecosystems.

Enhancing Role of Nitrogen Fixation in Biogeochemical Cycles of the Pacific Arctic

open access: yesGlobal Change Biology, Volume 32, Issue 5, May 2026.
Composite mean fields of sea surface temperature and sea‐ice distribution for September during 2015–2024, comparing years with high (2015, 2016, 2021) and low (2017, 2019, 2023) sea‐ice coverage. Earlier sea‐ice melt can promote the advection of diazotrophs (UCYN‐A2 and their haptophyte hosts) from the Bering Sea into the Beaufort Sea basin, where ...

A Global Review of Salt Marsh Restoration: Why Simpler, Context‐Specific Strategies Can Outperform Complex Approaches

open access: yesGlobal Change Biology, Volume 32, Issue 5, May 2026.
Salt marshes are vital coastal ecosystems, yet restoration outcomes remain highly variable and difficult to predict. We present the first global meta‐analysis comparing active salt marsh restoration interventions across physical, biotic and functional attributes.

Predicting Biochar‐Induced Changes in Soil Organic Carbon With Ensemble Machine Learning

open access: yesGCB Bioenergy, Volume 18, Issue 5, May 2026.
We developed an ensemble machine learning (ML) framework, combining Extremely Randomized Trees (ExtraTrees), Light Gradient Boosting Machine (LightGBM), and Categorical Boosting (CatBoost) regressors, to model SOC responses to biochar application using a globally curated dataset of 800 field observations.

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2

open access: yesPlant, Cell &Environment, Volume 49, Issue 5, Page 2654-2672, May 2026.
ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.
