Estructura, composición florística y almacenamiento de carbono en bosques nativos del páramo de Anaime, Tolima, Colombia

open access: yesCiência Florestal, 2019
Paramos have a high environmental importance due to their high plant and animal endemism, water regulation and carbon storage. In this work, the structure and composition of the tree vegetation were characterized as well as carbon storage in aboveground ...

Beyond species means – the intraspecific contribution to global wood density variation

open access: yesNew Phytologist, EarlyView.
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

Overcoming barriers to build partnerships for managing plant invasions under global change

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Non‐native plant invasions are a cross‐boundary conservation challenge, requiring coordinated management and policy responses underpinned by science. Global change is expected to exacerbate this challenge by changing abiotic and biotic drivers of invasive plant distribution, abundance, and impact. Current approaches may no longer be effective,

Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1992-2009, February 2026.
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

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

open access: yesJournal 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.
