Pyrogenic plants dominate many fire-prone ecosystems. Their prevalence suggests some advantage to their enhanced flammability, but researchers have had difficulty tying pyrogenicity to individual-level advantages. Based on our review, we propose that enhanced flammability in fire-prone ecosystems should protect the belowground organs and nearby propagules of certain individual plants during fir...
Forest fires represent a quite complex environment and an accurate prediction of the fires generated is crucial when trying to react quickly and effectively in such a critical situation. In this study, an hybrid system is applied to predict the evolution of forest fires. The Case-Based Reasoning methodology combined with a summarization of SOM ensembles algorithm has been used to face this prob...
In September and October 2015 widespread forest and peatland fires burned over large parts of maritime southeast Asia, most notably Indonesia, releasing large amounts of terrestrially-stored carbon into the atmosphere, primarily in the form of CO2, CO and CH4. With a mean emission rate of 11.3 Tg CO2 per day during Sept-Oct 2015, emissions from these fires exceeded the fossil fuel CO2 release r...
The El Niño Southern Oscillation (ENSO) is a climate-forcing mechanism that has been shown to affect precipitation and the occurrence of wildfires in many parts of the world. In the southern United States and northern Mexico, warm events (El Niño) are associated with moist winter conditions and fewer fires, while cool events (La Niñia) tend to favor dry winters and more fires. We tested this re...

Each year, thousands of fires occur on public lands. The vast majority of these fires are effectively suppressed in initial attack at a relatively small size, usually an acre or two, or less. Of fires that exceed initial attack, most are suppressed in extended attack and rarely exceed 100 acres or more. However, for a small proportion of all fires, generally less than 1%, unusual environmental,...
The effects of the fires that burned over 4.7 million ha of Indonesia’s tropical forests during 1997 and 1998 are largely unknown. We assess the immediate impacts of these fires on five forest areas representing several different habitats in Kalimantan 1-2 months after the fires went out. Comparisons of transects in burned and unburned forest areas were conducted at three sites: Tanjung Puting ...
F ood on the stove and grease fires are common responses for fire departments in off-campus housing communities. Like most fires and the associated responses, many could be prevented with a simple awareness to cooking basics – or Cooking 101. The Fire Problem: Cooking fires are a leading cause of fires in any household, but several factors increase the frequency of off-campus cooking incidents;...
The accident of the Chernobyl nuclear power plant (ChNPP) in 1986 was probably the worst environmental disaster in the past 30 years. The fallout and accumulation of radionuclides in the soil and vegetation could have long-term impacts on the environment. Radionuclides released during large, catastrophic vegetation fires could spread to continental Europe, Scandinavia, and Russia. The potential...
