No single factor produces wildfires; rather, they occur when fire thresholds (ignitions, fuels,
and drought) are crossed. Anomalous weather events may lower these thresholds and …

There is growing interest in the application of alternative stable state (ASS) theory to explain
major vegetation patterns of the world. Here, we introduce the theory as applied to the …

Deforestation and drought are among the greatest environmental pressures on the Amazon
rainforest, possibly destabilizing the forest-climate system. Deforestation in the Amazon …

Tropical forests modify the conditions they depend on through feedbacks at different spatial
scales. These feedbacks shape the hysteresis (history-dependence) of tropical forests, thus …

Recent extreme wildfire seasons in several regions have been associated with exceptionally
hot, dry conditions, made more probable by climate change. Much research has focused on …

A bstract Across the tropics, climate change is increasing the frequency and severity of
wildfires, exposing tropical forests to the risk of shifting into an open vegetation state. A …

Robust tree regeneration following high‐severity wildfire is key to the resilience of subalpine
and boreal forests, and 21st century climate could initiate abrupt change in forests if postfire …

The southeastern Amazon has recently been shown to be a net carbon source, which is
partly caused by drying conditions. Drying depends on a number of factors, one of which is …

Tropical forests are complex systems containing myriad interactions and feedbacks with
their biotic and abiotic environments, but as the world changes fast, the future of these …

Wildfire occurrence is influenced by climate, vegetation and human activities. A key
challenge for understanding the risk of fires is quantifying the mediating effect of vegetation …
