Beyond species means – the intraspecific contribution to global wood density variation
New Phytologist, Volume 249, Issue 6, Page 2630-2651, March 2026.Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.ABSTRACT Climate change significantly threatens biodiversity, particularly in freshwater ecosystems, which host many endemic and threatened species. Among them, aeglids stand out as strictly endemic, ecologically important and highly threatened crustaceans, making them a relevant model for investigating the impacts of climate change on aquatic ...

Nitric oxide supersaturation in the surface waters of the oligotrophic Atlantic Ocean
Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.Abstract Atmospheric nitric oxide (NO) is a pollutant and climate‐relevant trace gas. Dissolved NO accumulates in the surface ocean and therefore the ocean is a natural source of atmospheric NO. It is generally assumed that NO in the surface ocean is produced photochemically from nitrite (NO2−).

Drivers of plant phenolic concentration across global drylands
Journal of Ecology, Volume 114, Issue 1, January 2026.This study advances the understanding of how biotic and abiotic stressors shape plant defence strategies in global drylands. The findings shed novel insights about how plant secondary metabolites and their associated functions shift in response to changes in climate and grazing pressure, two key global change drivers with significant implications for ...
