Wildfire activity enhanced during phases of maximum orbital eccentricity and precessional forcing in the Early Jurassic

Communications Earth & Environment, 2021
Increased fire activity in the Early Jurassic is related to changes in the hydrological cycle driven by enhanced seasonality due to orbital forcing, according to a mid-latitude sedimentary charcoal record spanning 350,000 years.

The optimum fire window: applying the fire–productivity hypothesis to Jurassic climate states [PDF]

Biogeosciences
Present-day fire frequency is related to a productivity–aridity gradient on regional and global scales. Optimum fire conditions occur at times of intermediate productivity and aridity, whereas fire is limited at the high productivity (moisture) and ...

Quantifying responses of dung beetles to fire disturbance in tropical forests: the importance of trapping method and seasonality. [PDF]

PLoS ONE, 2011
Understanding how biodiversity responds to environmental changes is essential to provide the evidence-base that underpins conservation initiatives. The present study provides a standardized comparison between unbaited flight intercept traps (FIT) and ...

Surface Wildfire Regime and Simulation-Based Wildfire Exposure in the Golestan National Park, NE Iran

Fire, 2023
This research analyzes the spatiotemporal patterns of wildfire regime attributes (e.g., seasonality, size, frequency, and burn rate) across the Golestan National Park (GNP), northeast Iran over the last two decades.

Division of the tropical savanna fire season into early and late dry season burning using MODIS active fires

International Journal of Applied Earth Observation and Geoinformation, 2023
Tropical savannas and grasslands are the most frequently burned biome in the world, and fire has an important role in sustaining ecosystem processes. Modern management of fires in savannas has roots in traditions stretching back centuries, and nowadays earth observation data is incorporated extensively in fire management practices. In tropical savannas

Impact of seasonal cycles on host-pathogen dynamics and disease mitigation for Batrachochytrium salamandrivorans

Global Ecology and Conservation, 2019
Seasonal cycles have a demonstrated effect on the dynamics of human and animal diseases. However, their quantitative implications for disease mitigation in wildlife are less well studied.

Success of post-fire plant recovery strategies varies with shifting fire seasonality

Communications Earth & Environment, 2022
Post-fire recovery success after fires that occur outside of the historical fire season varies between fire response traits, which may impact long term ecosystem composition under changing fire regimes, according to a global systematic meta-analysis.

Repeated Seasonal Fires Drive Soil Nutrient Redistribution Across Depths in a Namibian Savanna, Kavango West Region, Namibia

Fire
Fire is a key ecological driver in savanna systems, influencing soil biogeochemical processes by releasing nutrients but also causing potential losses through volatilization and leaching. In this study, we investigated how fire seasonality and soil depth

COMPARISON BETWEEN DIFFERENT VERSIONS OF INPE'S FIRE RISK MODEL FOR THE BRAZILIAN BIOMES [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Fires are intrinsic disturbances in ecosystems functioning and structure in fire-prone biomes. In recent decades there has been an increase in the number of fire events in Brazilian biomes, especially due to misuse of fire in the land use and ...
