Dispersal and delimitation: Phylogenomics of Connaraceae prompts revised generic delimitation in Cnestideae and reveals global biogeographic patterns

TAXON, Volume 75, Issue 2, April 2026.
Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

The Conditions for Emissions: Exploring the Dynamics of Carbon Policy Emissions Across the United States

Politics &Policy, Volume 54, Issue 2, April 2026.
ABSTRACT In this paper, we investigate the adoption of carbon pricing policies within the U.S. across states. While policymakers have many tools at their disposal, carbon pricing is a policy option that utilizes market theories to curtail harmful effects from emissions through pricing structures.

Calibration and evaluation of a carbon net primary productivity module based on the SIMPLE model

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract This study presents the carbon net primary productivity (CNPP) module, an implementation of the simple generic crop model (SIMPLE model) that we have extended to predict aboveground and belowground biomass production and carbon assimilation. The goal for this module is to predict biomass inputs at and below the soil surface, during and at the ...

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
