Aim: Biodiversity conservation relies in part on enduring habitat in protected areas. In fire-prone ecosystems, shifts in species’ ranges will result both from changes in climate and fire-catalysed vegetation change, which could lead to niche…

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…
Year Published:
Numerous research works, numerical simulations and real experiments have been dedicated to the use of Unmanned Aerial Vehicles (UAV) before, during and after wildfire occurrences, for multiple purposes including terrain and vegetation mapping for…
Year Published:
Wildfires often exhibit complex and dynamic behaviour arising from interactions between the fire and surrounding environment that can create a rapid fire advance and result in loss of containment and critical fire safety concerns. A series of…
Year Published:
Post-fire remote sensing provides a promising tool for assessing building damage, destruction, and defensive actions from wildland fire. However, limited studies exist to guide image acquisitions. Consequently, we compare remotely piloted aircraft…

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…
Year Published:
The increasing incidence of wildfires across the southwestern United States (US) is altering the contemporary forest management template within historically frequent-fire conifer forests. An increasing fraction of southwestern conifer forests have…
Year Published:
This research was designed to address the need for a more cohesive approach to managing wildfire risk in the western United States. This involves multiple entities with diverse, often competing policies, incentives, and practices who are not well-…
Year Published:
While managed fire often produces clear changes in aboveground functional diversity, we know little about how fire affects belowground fauna and their mediation of biogeochemical processes. Because soil micro- and mesofauna, particularly nematodes,…

A 106 acre (43 ha) aspen clone lives in the Fishlake National Forest in south-central Utah. Clones are comprised of multiple aspen stems, called ramets, which are genetically identical. This particular colony of ramets was named “Pando” (Latin for “…
Year Published:
Elevated fuel loads represent a wildfire hazard in a landscape. Reducing fuel load is one mitigation strategy commonly employed to decrease the severity and impact of wildfires. The planning of such fuel management operations, however, represents a…
Year Published:
Increases in Vapor Pressure Deficit (VPD) have been hypothesized as the primary driver of future fire changes. The Coupled Model Intercomparison Project phase 5 (CMIP5) models agree that western U.S. surface temperatures and associated dryness of…
Year Published:
Indigenous communities in the Pacific West of North America have long depended on fire to steward their environments, and they are increasingly asserting the importance of cultural burning to achieve goals for ecological and social restoration. We…
Year Published:
Human and natural disturbances are key drivers of change in forest ecosystems. Yet, the direct and indirect mechanisms which underpin these changes remain poorly understood at the ecosystem level. Here, using structural equation modelling across a…
Year Published:
Computer models used to predict forest and fuels dynamics and wildfire behavior inform decisionmaking in contexts such as postdisturbance management. It is imperative to understand possible uncertainty in model predictions. We evaluated sensitivity…
Year Published:
Wildfires pose a significant challenge to the natural and the built environments, as well as the safety and economic well-being of the communities residing in wildfire-prone areas. The electric power grid is specifically among the built environments…
Year Published:
Northern Eurasia is currently highly sensitive to climate change. Fires in this region can have significant impacts on regional air quality, radiative forcing and black carbon deposition in the Arctic which can accelerate ice melting. Using a MODIS-…
Year Published:
Catastrophic wildfires are often a result of dynamic fire behaviours. They can cause rapid escalation of fire behaviour, increasing the danger to ground-based emergency personnel. To date, few studies have characterised merging fire behaviours…

wo years ago, the crew of the Po- larstern, a German icebreaker frozen into Arctic sea ice, shot a green laser up into the night. The beam’s reflected light was meant to help researchers study icy winter clouds. Instead, the beam encountered…

Children and youth are among the most vulnerable to the devastating effects of disaster due to the physical, cognitive, and social factors related to their developmental life stage. Yet children and youth also have the capacity to be resilient and…
