The Proximal Drivers of Large Fires: A Pyrogeographic Study [PDF]

Frontiers in Earth Science, 2020
Variations in global patterns of burning and fire regimes are relatively well measured, however, the degree of influence of the complex suite of biophysical and human drivers of fire remains controversial and incompletely understood. Such an understanding is required in order to support current fire management and to predict the future trajectory of ...

Deforestation as the Prominent Driver of the Intensifying Wildfire in Cambodia, Revealed through Geospatial Analysis

Remote Sensing, 2023
Cambodia has the most fires per area in Southeast Asia, with fire activity have significantly increased since the early 2000s. Wildfire occurrences are multi-factorial in nature, and isolating the relative contribution of each driver remains a challenge.

Complex responses of birds to landscape‐level fire extent, fire severity and environmental drivers [PDF]

Diversity and Distributions, 2014
AbstractAimTo quantify bird responses to a large unplanned fire, taking into consideration landscape‐level fire severity and extent, pre‐fire site detection frequency and environmental gradients.LocationSouth‐easternAustralia.MethodsA major wildfire in 2009 coincided with a long‐term study of birds and provided a rare opportunity to quantify bird ...

Dominant Drivers of Seedling Establishment in a Fire-Dependent Obligate Seeder: Climate or Fire Regimes? [PDF]

Ecosystems, 2013
Climate change is causing fire regime shifts in ecosystems worldwide. Plant species with regeneration strategies strongly linked to a fire regime, such as obligate seeders, may be particularly threatened by these changes. It is unclear whether changes in fire regimes or the direct effects of climate change will be the dominant threats to obligate ...

Study on the socioeconomic and climatic effects of forest fire incidence in the Changbai Mountain area based on a cross-classified multilevel model

Geomatics, Natural Hazards & Risk, 2023
The occurrence of forest fires is determined by fuel, climate and ignition sources at different temporal and spatial scales. However, most analyses are performed only on a single scale, and few comprehensive statistical analyses elaborate on the cross ...

How climate change and fire exclusion drive wildfire regimes at actionable scales

Environmental Research Letters, 2021
Extreme wildfires are increasing in frequency globally, prompting new efforts to mitigate risk. The ecological appropriateness of risk mitigation strategies, however, depends on what factors are driving these increases. While regional syntheses attribute

Microbial Community Responses to Alterations in Historical Fire Regimes in Montane Grasslands

Diversity, 2023
The influence of fire regimes on soil microbial diversity in montane grasslands is a relatively unexplored area of interest. Understanding the belowground diversity is a crucial stepping-stone toward unravelling community dynamics, nutrient sequestration,

Promoting Low-Risk Fire Regimes: An Agent-Based Model to Explore Wildfire Mitigation Policy Options

Fire, 2023
Landscape patterns and composition were identified as key drivers of fire risk and fire regimes. However, few studies have focused on effective policymaking aimed at encouraging landowners to diversify the landscape and make it more fire-resilient.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

The interaction between temperature and rainfall determines the probability of tropical forest fire occurrence in Hainan Island

Frontiers in Forests and Global Change
Severe forest fires have erupted in numerous tropical regions globally, threatening carbon storage in tropical ecosystems, the survival of plant species, and human health.
