Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers

New Phytologist, Volume 252, Issue 1, Page 69-86, October 2026.
Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.

Acorn caching hotspots of the Eurasian jay in pine plantations: Ecological basis for understorey management to assist oak regeneration

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
Our findings show that Eurasian jay dispersal activity depends on specific understorey structures when selecting caching microsites—particularly shrub cover and standing pines. These features could be directly shaped by management to promote assisted natural oak regeneration.

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1304-1321, July 2026.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

Almacenamiento prehispánico

, 2012
En su obra Les Chasseurs-cueilleurs ou l’origine des inégalrtés (1982), Alain Testart insiste en el papel que la práctica del almacenamiento pudo haber cobrado en el origen de las desigualdades en el seno de los grupos humanos, en particular entre las bandas de cazadores recolectores y, especialmente, aquellas más o menos sedentarizadas.

How Surface Reconstruction Drives Heterogeneous Bulk Delithiation in Single‐Crystalline Ni‐Rich Layered Oxide Cathodes

Small Science, Volume 6, Issue 5, May 2026.
Through multi‐rate operando X‐ray diffraction and soft X‐ray absorption spectroscopy, we demonstrate how surface‐level changes in aged single‐crystalline Ni‐rich LiNixMnyCo1−x−yO2 particles can directly affect bulk Li‐ion diffusion. The effect of this phenomenon on the electrochemical performance is also quantified using single‐layer pouch cells under ...

Estimation of CO2 Emissions in Fault Systems at a Global Scale

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Influenced by tectonic, geophysical, and environmental aspects, the release of carbon dioxide (CO2) in fault systems is a fundamental component of Earth's carbon cycle. Appreciating their contribution to natural greenhouse gas flow depends on knowing these emissions.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle

Conservation Biology, Volume 40, Issue 2, April 2026.
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We
