Different types of plant tissues and resin can account for the wax lipids found in sedimentary contexts and archaeological samples. Consequently, there is increasing research to characterize the fatty acid carbon isotope ratios of different plant…

In this episode of Fire Ecology Chats, Fire Ecology editor Bob Keane talks with Megan Friggens and Rachel Loehman about results from their study that identified the environmental and climate variables that best predict observed fire severity and…

Background: Wildfires of uncharacteristic severity, a consequence of climate changes and accumulated fuels, can cause amplified or novel impacts to archaeological resources. The archaeological record includes physical features associated with human…

This seminar is part of the USFS Missoula Fire Lab Seminar Series.
The need for science to improve the application of prescribed fire has never been greater. Increasing complexity, be it from altered land use patterns, changing climate, or invasive…

This study describes a multivariate statistical model (derived using partial least squares regression, PLS-R) that derives charring intensity (reaction temperature and duration) from the attenuated total reflectance (ATR) Fourier Transform Infrared…

An increasingly accepted paradigm in conservation attributes valued modern ecological conditions to past human activities. Disturbances, including prescribed fire, are therefore used by land managers to impede forest development in many potentially…

Here, we show that the last century of fire suppression in the western U.S. has resulted in fire intensities that are unique over more than 900 years of record in ponderosa pine forests (Pinus ponderosa). Specifically, we use the heat-sensitive…

Warm summer temperatures and longer fire seasons are promoting larger, and in some cases, more fires that are severe in low- and mid-elevation, dry mixed-conifer forests of the Northern Rocky Mountains (NRM). Long-term historical fire conditions and…

Paleofire studies frequently discount the impact of human activities in past fire regimes. Globally, we know that a common pattern of anthropogenic burning regimes is to burn many small patches at high frequency, thereby generating landscape…

The high-resolution Adriatic RF93-30 core shows changes in its microcharcoal record, which correlate to terrestrial fires from the last 7000 years. Pollen and microcharcoals were transported by wind and fluvial transport from the sedimentary basin,…
