Increasing prevalence of severe fires change the structure of arthropod communities: Evidence from a meta-analysis
<p>1. Animal ecology and evolution are shaped by environmental perturbations, which are undergoing unprecedented alterations due to climate change. Fire is one such perturbation that causes significant disruption by causing mortality and altering habitats and resources for animals. Fire regimes are changing on a global scale, but the effects of these changes on animal communities are poorly understood. Arthropods are one of the most ubiquitous and diverse animal taxa on the planet and their populations are sensitive to environmental change. Given their wide-ranging impacts on ecosystem functioning, a better understanding of arthropod responses to changing fire regimes is critical and may also provide more general insights into how other groups might respond to fire.</p> <p>2. Here, we provide a comprehensive meta-analytical assessment of how fire influences the arthropod community across habitats and functional groups. Using data from 130 peer-reviewed papers across the globe, we tested how a variety of fire characteristics, including management regime, severity, and time-since-fire affect arthropod populations and communities across habitats.</p> <p>3. Our results show that arthropod communities display substantial variation in response to fire and that community-level responses are most likely to be detected within the first year. Responses also vary depending on fire characteristics and habitat. Specifically, while community metrics such as diversity were increased by low severity fires, they were reduced by high severity fires. Likewise, evenness increased after prescribed burns but was reduced after wildfire. Measures of arthropod community structure decreased following fires in deserts and forests.</p> <p>4. Across the entire arthropod community, fire also had variable effects on community diversity. Fire tended to have a negative effect size on arthropods across life stages, but responses did vary among groups. Nearly all functional groups exhibited a negative response to fire with the exception of herbivores, for which abundance, diversity, and richness increased after fire.</p> <p>5. Our results suggest that the increasing prevalence of high-severity wildfires is changing the structure of arthropod communities. Given their ubiquitous presence and diverse roles in terrestrial ecosystems, these community changes are likely to affect ecosystem functioning in various ways, including through increased herbivory.</p>

Fire Breathing Snail Car
I shot this quick and dirty photoscan early one morning at Makerfaire before the crowds engulfed it. The scan is not as good as Jon's amazing car deserves, but it is a very difficult subject to capture.

Remotely sensed vegetation phenology drives large fires spreading in northwestern Europe
<p><span>In recent years, an increase in the frequency of large fires has been reported in NW Europe, a region where a deeper understanding of the conditions conducive to dangerous fire behavior is needed. This study builds on recent efforts to characterize rate of spread (ROS) variation in the region and delves into vegetation and climatic drivers. For 58 large fires in this region, we analyzed phenology (using the temporal variation of satellite-measured vegetation indices) and weather, (using as the Canadian Fire Weather Index System). Results suggest that short-term vegetation greenness play an important role in predicting ROS: High greenness correlated non-linearly with low ROS, and fires spreading in the growing season described a drastic reduction in spread. Fire weather did not prove to be a good indicator of fast spread. Contrary to expectations, high danger related to fire weather ratings were associated with low ROS. This indicates the importance of temporal variability of vegetation greenness, the capability of remote sensing in capturing times when an ignition could generate fast-spreading fires, and the need for a fire weather danger rating system tailored to regional conditions.</span></p> <p> </p> <p><span>This is the repository for the clusterd fire events and its isochrones, and ROS vectors.</span></p>
Dataset related to publication: Landcover-categorized fires respond distinctly to precipitation anomalies in the South-Central United States
<p>Landcover-categorized fires respond distinctly to precipitation anomalies in the South-Central United States</p> <p>Kátia Fernandes and Sen g. Young</p> <p>doi: 10.3389/fenvs.2024.1433920</p> <p>Abstract</p> <p>Satellite detection of active fires have contributed to advance our understanding of fire ecology, fire and climate dynamics, fire emissions and how to better manage the use of fires as a tool. In this study we use 12 years (2012-2023) of active fire data combined with landcover information in the South-Central United States to derive a monthly, <strong>open access dataset of categorized fires.</strong> This is done by calculating a fire predominance index used to rank fire prone land covers, which are then grouped into four main landscapes: grassland, forest, wildland and crop fires. County level aggregated analyses reveal spatial distributions, climatologies, and peak fire months that are particular to each fire type. Using the Standardized Precipitation Index (SPI), it is found that during climatological fire peak-month, SPI and fires exhibit an inverse relationship in forests and crops, whereas grassland and wildland fires show less consistent inverse or even direct relationship with SPI. This varied behavior is discussed in the context of landscapes’ responses to anomalies in precipitation, and fire management practices, such as prescribed fires and crop residue burning. In a case study of Osage County (OK) we find that large wildfires, known to be closely related to climate anomalies, occur where forest fires are located in the county and absent in areas of grassland fires. Weaker grassland fires response to precipitation anomalies can be attributed to the use of prescribed burning, which are normally planned under environmental conditions that facilitate control and thus avoided during droughts. Crop fires on the other hand, are set to efficiently burn residue and practiced more intensely in drier years than in wetter, explaining the consistently strong inverse correlation between fires and precipitation anomalies. In our increasingly volatile climate, understanding how fires, vegetation, and precipitation interact has become imperative to prevent hazardous fire conflagrations and to better manage ecosystems.</p>
A Multi-site Passive Approach for Studying the Emissions and Evolution of Smoke from Prescribed Fires
<p>The uploaded data consists of ground measurements of CO, O3, PM2.5 mass, and PM2.5 BC taken at Fort Moore, Columbus, GA, USA, during the prescribed burning seasons of 2021-2022. This data was used in a manuscript that will be submitted to ACP for review. Each Excel file includes a header that details the measurement location, instruments used, and units. The data is provided in its highest resolution and can be averaged over different durations to smooth out fluctuations and cancel noise at background levels.</p>
