Maximum water stress is decoupled from climate, traits, and growth in a xeric oak

New Phytologist, Volume 251, Issue 5, Page 2392-2406, September 2026.
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

Morphological, Molecular, and Isotopic Approaches to Termite Ecology: A Mangrove Case Study

Biotropica, Volume 58, Issue 3, May 2026.
Termite communities in Caribbean mangroves, though species‐poor, sustain crucial decomposition and nutrient cycling. Their overlapping niches and stochastic assembly highlight termites' resilience and ecological importance in supporting the functioning of these challenging coastal ecosystems.

Blockchain and Quantum Technologies for Securing the Global Nuclear Supply Chain: Synergies, Applications, Technical Challenges and Opportunities

Journal of Critical Infrastructure Policy, Volume 7, Issue 1, Spring/Summer 2026.
ABSTRACT The infiltration of counterfeit, fraudulent, and suspect items into civil nuclear supply chains, notably within power generation and medical isotope production, poses severe safety and security threats. The ever‐increasing growth in nuclear installations (70 power plants are under construction and another 100 are in the planning stage) and the

Vegetative stage and soil horizon respectively determine direction and magnitude of rhizosphere priming effects in contrasting tree line soils

Functional Ecology, Volume 38, Issue 9, Page 1984-2002, September 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Tree lines in high latitudes and high altitudes are considered sentinels of global change. This manifests in accelerated encroachment of trees and shrubs and enhanced plant productivity, with currently unknown implications for the carbon balance of these biomes.

Drought effects in Mediterranean forests are not alleviated by diversity‐driven water source partitioning

Journal of Ecology, Volume 112, Issue 9, Page 2107-2122, September 2024.
Tree species diversity promotes below‐ground water source partitioning in mixed oak and pine stands, potentially reducing competition for water in more diverse ecosystems. Yet, these results show that it is insufficient to buffer the adverse impacts of severe droughts on above‐ground tree carbon and water use, leading to higher water stress, especially
