A typographical error in the original version of Table S1 as posted in 2012 has been brought to our attention. The coefficient in the Thomas (1963) equation (0.02665) is correct but the exponent should have read 0.667 and not 0.46. Any calculations…

Wildfires significantly influence ecosystem patterns and processes on a global scale. In many cases, they pose a threat to human lives and property. Through greenhouse gas emissions, wildfires also directly contribute to climate change. The…

One of the main sources of greenhouse gases is forest fire, with carbon dioxide as its main constituent. With increasing global surface temperatures, the probability of forest fire events also increases. A method that enables rapid quantification of…

Wildfire size and frequency have increased in the western United States since the 1950s, but it is unclear how seeding treatments have altered fire regimes in arid steppe systems. We analyzed how the number of fires since 1955 and the fire return…

Wildfires present an increasing threat to communities through impacts that include destruction of homes or outbuildings, evacuations, damage to public infrastructure, and economic disruption. Effective fire management entails identifying and…

Delaying protective action decision making in wildfire is inconsistent with fire authorities’ advice and is associated with fatalities. A comprehensive understanding of why at-risk residents wait and see whether they will evacuate from a wildfire or…

Expert opinion can be a valuable tool for informed decision making. Concerning wildfire susceptibility reduction at the landscape scale, forest ecosystem experts play a key role in offering advice about appropriate fuel management practices to be…

Fire plays a role in the vast majority of terrestrial ecosystems. Researchers have discovered that the negative effects of prescribed fire on soil, water and vegetation are transitory, and that benefits are much greater. This paper presents a…

Understanding how abiotic disturbance and biotic interactions determine pollinator and flowering‐plant diversity is critically important given global climate change and widespread pollinator declines. To predict responses of pollinators and…

A significant amount of research has examined what motivates people living in fire-prone areas to mitigate their wildfire risk (i.e. engage in activities that reduce vulnerability and the effects of a wildfire on an individual’s property). However,…
