CHANGES IN FIRE SEASON PRECIPITATION IN IDAHO AND MONTANA FROM 1982-2006
Abstract. Fire season precipitation trends were investigated using daily rainfall data obtained from seventy-six Remote Automated Weather Stations (RAWS) across Idaho and Montana for the period 1982 to 2006. Missing and erroneous values from each station were corrected with gridded data from the …

Beaver moderated fire resistance in the North Cascades and potential for climate change adaptation
<p>Climate change and fire suppression have altered historic fire regimes, creating conditions for larger, more intense fires. Intense burns can alter watershed hydrology, increasing the potential for harmful channel incision, which impairs riparian ecosystem function by lowering the water table, …

Heat acclimatization during seasonal wildfire suppression
… determine heat acclimatization across a 4-month fire season in the western United States. Methods: Wildland firefighters (WLFF) (n =12) and non-WLFFs (n =14) completed a 60-min heat stress trial (treadmill walking at 50% peak VO2) in a climate controlled chamber (43.3°C, 33% RH) prior to and …

The Effects of Fire on the Vernal Herbs of an Eastern Mesic Forest
<p><sup></sup>The effects of fire on vernal herbs of the mesic forests of eastern North America are poorly understood. I studied the influence of prescribed fire on species richness, abundance of rare and common species, and density of exotics in the vernal herbaceous layer. To determine these …

Long-term effects of prescribed fire on vegetation structure, dynamics, and tree growth in red pine (Pinus resinosa Ait.) forests in north central Minnesota.
Prescribed fire is increasingly being viewed as a valuable tool for mitigating the ecological consequences of long-term fire suppression within fire-adapted forest ecosystems. While the use of burning treatments in northern temperate conifer forests has at times received considerable attention, the …

Evaluation of Wildland Firefighter Leadership
… crisis leaders and followers, such as wildland firefighters make decisions in high-stress environments. In this study, wildland firefighters were examined to assess their decision-making skills using a wildland fire simulation computer game called the Networked Fire Chief (NFC). These results …

Spatiotemporal Distribution of Siberian Wildfires and Impacts from Meteorological and Climatic Factors
Wildfire is a major disturbance affecting carbon cycling, land–atmosphere energy exchange, and ecological security in high-latitude ecosystems. Siberia is one of the most fire-prone regions in the high latitudes of the Northern Hemisphere, and the spatiotemporal variability of its wildfire activity …

Burning for birds : the response of bird communities to recent fire history in the Serengeti ecosystem
Fire is a ubiquitous ecosystem process with important implications for savanna ecology and conservation. In this study we aimed to explore the short-term and long-term effects of recent fire history on bird communities in the greater Serengeti savanna ecosystem in Tanzania. The study investigated …

A comparison and synthesis of polar-orbiting and geostationary observations of African biomass burning
… independently detect and characterize all active fires from ignition to extinction. Instead SEVIRI (at 15 min temporal resolution) fails to detect relatively smaller and/or lower intensity fires within its coarser 3 km pixels while MODIS (at 1 km spatial resolution) fails to detect fires between …

Spatiotemporal Variability of CO2, Solar-Induced Fluorescence, And Precipitation Over the Tropical Rainforests
… ecosystems change forest dynamics during the dry/fire season, transitioning from an atmospheric CO2 sink to a CO2 source. The Amazon basin, Congo basin, and the tropical Indo-Pacific play vital roles in biospheric processes, which contribute to Earth’s atmospheric CO2 concentration. This …

The differences in grass species composition and the effects on fire behaviour in an African mesic savanna
Fire is a key determinant of savanna dynamics, particularly with respect to its influence on vegetation dynamics. The grass species composition and structure of savannas have impacts on fire behaviour through their differing fuel characteristics related to each species specific phenologies and …

Vegetation and Forest Fire Dynamics in Alberta: A Ground and Remote Sensing Data Analysis
… analysis of the interplay between forest fires and vegetation dynamics in Alberta, Canada, under the lens of climate change. By synthesizing data from remote sensing, climate records, and fire databases, the study reveals the intricate relationships between vegetation cover changes and …

The role of human disturbance in the dynamics and distribution of sand forest in and around Tembe Elephant Park, KwaZulu-Natal.
… The first disturbance investigated was that of fire and its role in determining the spatial patterning of sand forest at the landscape level. Secondly human disturbance was investigated i11 the fom1 of utilisation of forest products and the effects of this on the d}11amics of sand forest as a …

Firestorms in a mesic savanna-forest mosaic
… are maintained by positive feedback loops with fires, promoting fires in savannas and excluding fires in forests. Occasional extreme fires do however burn into forest edges and cause extensive mortality. So, while our understanding of bistability in these systems has advanced, our understanding …
