Fires, Hurricanes, and Volcanoes: Comparing Large Disturbances [PDF]

BioScience, 1997
T he importance of natural disturbances in shaping landscapes and influencing ecosystems is now well recognized in ecology (e.g., Pickett and White 1985, Turner 1987, White 1979). Disturbance can be defined generally as any relatively discrete event in time that disrupts ecosystem, community, or population structure and changes resource or substrate ...

Fire disturbance and climate change: implications for Russian forests

Environmental Research Letters, 2017
Change in the Russian boreal forest has the capacity to alter global carbon and climate dynamics. Fire disturbance is an integral determinant of the forest’s composition and structure, and changing climate conditions are expected to create more frequent ...

Scenarios in tropical forest degradation: carbon stock trajectories for REDD+

Carbon Balance and Management, 2017
Background Human-caused disturbance to tropical rainforests—such as logging and fire—causes substantial losses of carbon stocks. This is a critical issue to be addressed in the context of policy discussions to implement REDD+.

The Rapid Initial Community Builder (RICB) V1.1 for LANDIS-II

MethodsX
Forest succession, or ecosystem process models, can aid in many land management decisions as they inherently incorporate ecological processes to predict how disturbances impact the resilience of the forest and its potential future structure.

Empirical analyses of the factors influencing fire severity in southeastern Australia

Ecosphere, 2021
Fire severity is a key component of fire regimes, and understanding the factors affecting it is critical given the increasing incidence of wildfires globally.

Contrasting effects of urbanization and fire on understory plant communities in the natural and wildland–urban interface

Ecosphere, 2023
As human populations expand and land‐use change intensifies, terrestrial ecosystems experience concurrent disturbances (e.g., urbanization and fire) that may interact and compound their effects on biodiversity.

A minimal model of fire-vegetation feedbacks and disturbance stochasticity generates alternative stable states in grassland–shrubland–woodland systems

Environmental Research Letters, 2015
Altered disturbance regimes in the context of global change are likely to have profound consequences for ecosystems. Interactions between fire and vegetation are of particular interest, as fire is a major driver of vegetation change, and vegetation ...

Identifying Conifer Tree vs. Deciduous Shrub and Tree Regeneration Trajectories in a Space-for-Time Boreal Peatland Fire Chronosequence Using Multispectral Lidar

Atmosphere, 2022
Wildland fires and anthropogenic disturbances can cause changes in vegetation species composition and structure in boreal peatlands. These could potentially alter regeneration trajectories following severe fire or through cumulative impacts of climate ...

Fire regime: history and definition of a key concept in disturbance ecology [PDF]

Theory in Biosciences, 2010
"Fire regime" has become, in recent decades, a key concept in many scientific domains. In spite of its wide spread use, the concept still lacks a clear and wide established definition. Many believe that it was first discussed in a famous report on national park management in the United States, and that it may be simply defined as a selection of a few ...

Wildfire affects boreal forest resilience through post-fire recruitment in Northeastern China

Ecological Indicators, 2022
Climate change has increased the severity, frequency, and impact of fire disturbance on boreal forests worldwide. Unusual fire events can trigger a shift from needle-leaf dominated forests to broad-leaf dominated forests, altering the original succession
