Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)
Land Degradation &Development, EarlyView.ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...

Time to burn: landscape drivers of fuel trait variability and fire regime in savanna ecosystems
Oikos, EarlyView.Fuel traits are important determinants of fire behavior and regime in savannas and, thus, of how fire affects plant communities. However, whether these traits are correlated, predictable and how they are influenced by biotic and abiotic drivers remain to be rigorously evaluated.

ChemistryOpen, EarlyView.Electrolyte temperature significantly affects electrocatalyst performance in water splitting reactions. Catalysts synthesized by solution combustion synthesis were evaluated for oxygen evolution activity at different temperatures. Elevated temperatures reduced overpotential and increased current density, reflecting enhanced reaction kinetics and ...

ChemistryOpen, EarlyView.Targeting a nucleotide‐sensitive groove on Hsp70 that binds the Bim BH3 helix, we integrate structures, biophysics, and SAR from peptides, fragments, and phenalene‐dicarbonitrile “wedges.” These disrupt the Hsp70–Bim complex with sub‐µM cellular engagement and in vivo activity while sparing Hsp90/mortalin.

People and Nature, EarlyView.Abstract Managing wildfire risk requires consideration of complex and uncertain scientific evidence as well as trade‐offs between different values and goals. Conflicting perspectives on what values and goals are most important, what ought to be done and what trade‐offs are acceptable complicate those decisions.
