Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates
Land Degradation &Development, EarlyView.ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

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 ...
