Forest fires are key ecosystem modifiers affecting the biological, chemical, and physical attributes of forest soils. The extent of soil disturbance by fire is largely dependent on fire intensity, duration and recurrence, fuel load, and soil…

Background: Model simulations of wildfire spread and assessments of their accuracy are needed for understanding and managing altered fire regimes in semiarid regions. The accuracy of wildfire spread simulations can be evaluated from post hoc…

There remains a high level of ambiguity around post-fire grazing management. The Lodgepole Complex fire burned 109,346 ha in east-central Montana in July 2017, including areas previously burned in 2003 by the Bureau of Land Management for fuels…
Year Published:
Climate warming and an increased frequency and severity of wildfires are expected to transform forest ecosystems, in part through altered post-fire vegetation trajectories. Such a loss of forest resilience to wildfires arises due to a failure to…
Year Published:
Development into the wildland-urban interface, combined with heat and drought, contribute to increasing wildfires in the U.S. West and a range of damages including recreation site closures and longer-term effects on recreation areas. A choice…

Modern Pyromes: Biogeographical Patterns of Fire Characteristics across the Contiguous United States
In recent decades, wildfires in many areas of the United States (U.S.) have become larger and more frequent with increasing anthropogenic pressure, including interactions between climate, land-use change, and human ignitions. We aimed to…

Climate change represents a threat to life; as such, it is associated with psychological disorders. The subjective perceptions of life impacts from different traumatic experiences develop understanding and the enable predictions of future…
Year Published:
Fire has transformative effects on soil biological, chemical, and physical properties in terrestrial ecosystems around the world. While methods for estimating fire characteristics and associated effects aboveground have progressed in recent decades…
Year Published:
Seed dormancy varies greatly between species, clades, communities, and regions. We propose that fireprone ecosystems create ideal conditions for the selection of seed dormancy as fire provides a mechanism for dormancy release and postfire conditions…
Year Published:
Ecologists have long debated the relative importance of biotic interactions versus species-specific habitat preferences in shaping patterns of ecological dominance. In western North America, cycles of fire disturbance are marked by transitions…
Year Published:
The impact of smoke from wildland fires on human health is currently a serious concern due to the high levels of emitted gases and particulate matter that affect populations and firefighters. In recent decades, scientific developments regarding…

Mountain snowpacks provide 53–78% of water used for irrigation, municipalities, and industrial consumption in the western United States. Snowpacks serve as natural reservoirs during the winter months and play an essential role in water storage for…
Year Published:
Snowpack in the western U.S. is critical for water supply and is threatened by wildfires, which are becoming larger and more common. Numerous studies have examined impacts of wildfire on snow water equivalent (SWE), but many of these studies are…
Year Published:
Recent increases in fire frequency and severity across the western US are triggering abrupt changes in ecosystem structure and composition, especially in lower montane forests, but consequences of fire-regime change for mesic, mixed-conifer forests…

Although bull trout (Salvelinus confluentus) and tailed frogs (Ascaphus montanus) have co-existed in forested Pacific Northwest streams for millennia, these iconic cold-water specialists are experiencing rapid environmental change caused by a…

In recent decades, wildfires in many areas of the United States (U.S.) have become larger and more frequent with increasing anthropogenic pressure, including interactions between climate, land-use change, and human ignitions. We aimed to…
Year Published:
Fire is a key determinant of vegetation structure and composition in ecosystems worldwide and is therefore an important management tool. The “pyrodiversity hypothesis”, which postulates that biodiversity will increase as fire diversity increases,…
Year Published:
Wildfires produce a mosaic of burned and unburned patches across varying temporal and spatial scales and provide a range of essential ecosystem services. Fire perimeters mark the separation between the burned and unburned matrix of a fire. Analysis…
Year Published:
Belowground bud bank regeneration is a successful strategy for plants in fire-prone communities. It depends on the number and location of dormant and viable buds stored on belowground organs. A highly diverse belowground bud-bearing organ system…
Year Published:
Background: Humans have altered fire regimes across ecosystems due to climate change, land use change, and increasing ignition. Unprecedented shifts in fire regimes affect animals and contribute to habitat displacement, reduced movement, and…
