Stomatal distribution and post‐fire recovery: Intra‐ and interspecific variation in plants of the pyrogenic Florida scrub

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Amphistomy, the presence of stomata on both leaf surfaces, can increase photosynthesis yet is uncommon across vascular plants. The relative infrequency of amphistomy is often attributed to high costs, such as transpirational water loss.

Deciphering fire tolerance of trees at the Amazonia–Cerrado transition by trait‐based approach: Implications from species to communities

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Understanding how fire impacts trees is essential for predicting the effects of novel fire regimes on plant diversity in the transition between the world's two most diverse biomes, the Cerrado and the Amazonia. Here we addressed knowledge gaps regarding physiological damage and mortality in transitional species within fire‐prone ...

Photocatalytic Co‐Reduction of CO2 and Nitrate over Porphyrin Metal–Organic Frameworks: Dual Atomic Active Site and Nanostructure Synergy Enhances C–N Coupling for Urea Production

open access: yesAngewandte Chemie, EarlyView.
A bimetallic porphyrin metal–organic framework with nanoflower‐like architecture is synthesized as a high‐performance photocatalyst for urea synthesis. The synergy between dual atomic active sites and nanostructure engineering enables an excellent performance with a urea yield of 2459.8 µg h−1 gcat−1 via photocatalytic co‐reduction of CO2 and nitrate ...

Climate‐change‐driven shifts in C3 and C4 grass distributions and leaf traits could lead to changes in community‐level flammability

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Climate change poses challenges to grasslands, including those of the North American Great Plains Region, where shifts in species distributions and fire dynamics are expected. Our present analysis focuses on remaining grasslands within this largely developed and agricultural region. The differential responses of C4 and C3 grass species
