Assessing contributions of deterministic versus stochastic processes to local species assembly: A field experiment with annual plant‐dominated communities in gypsum systems

Journal of Ecology, Volume 114, Issue 3, March 2026.
In this study, we experimentally show that stochasticity can play prominent roles in driving local species assembly in annual plant‐dominated communities of semiarid gypsum ecosystems. Drylands are traditionally viewed as restrictive environments that impose strong deterministic filtering effects, but neutral events can also contribute decisively to ...

Species functional traits affect regional and local dominance across western Amazonian forests

Journal of Ecology, Volume 114, Issue 1, January 2026.
Dominant tree species in western Amazonian forests show distinct functional trait combinations linked to habitat type: conservative traits in stressful habitats and greater plant size in less stressful environments. Local dominants are defined by resource conservation strategies and widespread dominants are defined by resource acquisition strategies. A

Revisiting Deere in an Extractivist Era: Agrarian Reform and Feminist Legacies in Coastal Ecuador

Journal of Agrarian Change, Volume 26, Issue 1, January 2026.
ABSTRACT This article examines how campesinas in coastal Ecuador have navigated shifting labour roles, financial precarity and ecological degradation under Plan Tierras, a state‐led land redistribution policy embedded in an extractivist model of agriculture.

Análisis del banco de semillas y su relación con la vegetación emergente en una clausura de la llanura pampeana

Ecología Austral, 2007
La regeneración de la comunidad vegetal, luego de sufrir algún tipo de disturbio, depende de la disponibilidad de propágulos cuya fuente primaria la constituye el banco de semillas del suelo.

Decadal survival of tropical pioneer seeds in the soil seed bank is accompanied by fungal infection and dormancy release

Functional Ecology, Volume 39, Issue 6, Page 1483-1494, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pioneer trees require high‐light environments for successful seedling establishment. Consequently, seeds of these species often persist in the soil seed bank (SSB) for periods ranging from several weeks to decades.

Landrace diversity and heritage of the indigenous millet crop fonio (Digitaria exilis): Socio‐cultural and climatic drivers of change in the Fouta Djallon region of Guinea

PLANTS, PEOPLE, PLANET, Volume 7, Issue 3, Page 704-718, May 2025.
White fonio (Digitaria exilis [Kippist] Stapf) is an understudied millet crop, indigenous to West Africa and cultivated in the region largely through traditional practices. This species is climate‐resilient, fast‐growing, nutritionally rich, and provides livelihoods and food security to rural communities.

Climb forest, climb: diverse disperser communities are key to assist plants tracking climate change on altitudinal gradients

New Phytologist, Volume 245, Issue 3, Page 1315-1329, February 2025.
Summary Climate change is forcing species to shift their distribution ranges. Animal seed dispersers might be particularly important in assisting plants tracking suitable climates to higher elevations. However, this role is still poorly understood due to a lack of comprehensive multi‐guild datasets along elevational gradients.
