Optimizing the Structure/Texture Coupling of Carbon Xerogels for High‐Performance Anodes of Sodium‐Ion Batteries in Glyme‐Based Electrolytes

Battery Energy, Volume 5, Issue 2, March 2026.
Carbon xerogels synthesized via a microwave‐assisted process were carbonized in the range of 1000°C–2800°C and evaluated as anodes for next‐generation sodium‐ion batteries. The material prepared at 1800°C showed optimal structural and textural properties and excellent electrochemical performance. Potential profile analysis provided insights into sodium

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

Enabling conditions for conservation on Indigenous and community lands

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Despite increasing evidence and general acceptance in global environmental policy of the significant role of Indigenous Peoples and local communities (IP&LC) in biodiversity conservation and climate change mitigation, an implementation gap remains between global policy and how conservation plays out on the ground.

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

New 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 ...

CORPORATE FUTURES, ENERGY TRANSITION, AND NATURAL PROSTHETICS IN COLOMBIA'S CESAR MINING CORRIDOR

Cultural Anthropology, Volume 41, Issue 1, Page 134-162, February 2026.
ABSTRACT This essay examines the socioecological transformations of mining and post‐mining landscapes in the mining corridor of the Cesar Department, northern Colombia. When an open pit mine is about to close or has recently closed, companies promote post‐mining strategies framed as ecosystem restoration and social compensation.
