Genetic progress in yield, biomass, and trait trade-offs in Chilean durum wheat before and after the Green Revolution under Mediterranean irrigated conditions

Frontiers in Sustainable Food Systems
Grain yield in wheat depends on both aboveground biomass production and harvest index (HI). As HI approaches its theoretical limit, future yield improvement is expected to rely increasingly on enhancing biomass production while maintaining efficient ...

Land use intensification results in abrupt transitions between extensively and intensively managed grasslands

Functional Ecology, Volume 40, Issue 11, Page 3577-3591, November 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding whether land use intensification causes regime shifts (i.e. persistent, large changes in ecosystem states) is of key importance for management, particularly if these shifts occur abruptly as thresholds in land use intensity are crossed.

First results on enzymatic activities in two salt marsh soils under different hydromorphic level and vegetation

EQA, 2015
Salt-marsh soils are soils characterized by non-permanent hydric saturation that, depending on factors like duration of submersion periods, are dominated by different salt-tolerant plant species.

Integrating Diverse Approaches, Actors, and Local Knowledge: Lessons From the 61st ATBC Meeting

Biotropica, Volume 58, Issue 6, November 2026.
With roots dating back to 1963, the Association for Tropical Biology and Conservation (ATBC) has broadened its biological focus to embrace the multidimensional nature of conservation. The 61st ATBC Meeting in Oaxaca, México (2025) emphasized integrating ecological, social, and cultural dimensions through diverse approaches, actors, and knowledge ...

Physiologia Plantarum, Volume 178, Issue 6, November/December 2026.
ABSTRACT Holm oak (Quercus ilex subsp. rotundifolia Lam.) is an evergreen tree that experiences a physiological deterioration of the photosynthetic apparatus associated with age‐dependent changes in net photosynthesis (AN), stomatal conductance (gs), mesophyll conductance (gm) and chloroplast surface area exposed to intercellular air space (Sc/S ...

From the Margins: Potential Coalitions in Centralized, High‐Capacity States

Policy Studies Journal, Volume 54, Issue 4, November 2026.
ABSTRACT The early stages of coalition formation remain an understudied area, particularly in centralized, high‐capacity political systems. Examining actor dynamics at this formative stage can reveal how coalitions form and how limited pluralism constrains their development.
