Microbiome‐mediated response to pulse fire disturbance outweighs the effects of fire legacy on plant performance

New Phytologist, 2021
Summary Fire plays a major role in structuring plant communities across the globe. Interactions with soil microbes impact plant fitness, scaling up to influence plant populations and distributions. Here we present the first factorial manipulation of both fire and soil microbiome presence to investigate their interactive effects on plant performance ...

Forest resilience to fire in eastern Amazon depends on the intensity of pre-fire disturbance

Forest Ecology and Management, 2020
Abstract Researchers and managers face the challenge of how to determine when frequency, spatial extent and magnitude of disturbances can overcome the resilience of forest ecosystems. Among the disturbances in tropical forests, the mid- and long-term impacts of fire are still poorly known, especially how fire interacts with selective logging. In this

Fire disturbance in Amazonian blackwater floodplain forests

Plant Ecology & Diversity, 2012
Background: Large fire scars were detected in floodplain forests of the middle Rio Negro in dry years of the 1990s, using satellite data. Aim: To relate fire years and river level anomalies to the Tropical Pacific Southern Oscillation Index (SOI); to measure fire damage and post-fire succession rate.

The pattern of fire disturbance in Liangshui Nature Reserve

Journal of Northeast Forestry University, 1996
Fire disturbance pattern of Liangshui Nature Reserve was studied by investigating fire scar tree and analyzing distribution of charcoal particle in soil-layer. The results show that, fire disturbance regular is related with the accumulation and disposition of fuels in space pattern.

Effects of fire disturbance on forest hydrology

Journal of Forestry Research, 2003
Fire is quite a common natural phenomenon closely related to forest hydrology in forest ecosystem. The influence of fire on water is indirectly manifested in that the post fire changes of vegetation, ground cover, soil and environment affect water cycle, water quality and aquatic lives.

Wave disturbances of the atmosphere due to large fires

Combustion, Explosion and Shock Waves, 1983
Because the mechanism responsible for generation of waves by sources acting over a prolonged period of time is still not clear, an artificial large-scale experiment was set up according to given specifications. Tests derived the following parameters: the dependence of the square of the amplitude of oscillations in the wind velocity at the source and on

Recovery of Forest Vegetation After Fire Disturbance

2009
Fire is the dominant form of disturbance in boreal forests (Wein and MacLean 1983; Van Cleve et al. 1986; Payette 1992; Rees and Juday 2002). In the Siberian cryolithic zone, ground fires are predominant among the disturbance factors; about 1.5% of the total forested area is damaged annually by wild fires (Sofronov et al. 1998).

Fire Disturbance of a Chironomid (Diptera) Community on Heathlands

The Journal of Applied Ecology, 1994
Three different heathlands (dry, mesic and tall) were submitted to prescribed fire either in spring or in summer in Brittany (France). After the fire, the terrestrial Chironomidae were studied for 4 years using emergence traps. The community consisted of eight chironomid species, of which five were numerically abundant and widespread at the regional ...

Exploitation of Copernicus Sentinels Data for Sensing Fire-Disturbed Vegetated Areas

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
This paper aims at investigating the use of microwave and optical images for the detection and characterization of fire scars in vegetated areas. To cope with this issue, Sentinel-1 (S-1) C-band synthetic aperture radar (SAR), and multispectral Sentinel-2 (S-2) multispectral data are used.

Soil N2O emissions in a Mediterranean shrubland disturbed by experimental fires

International Journal of Wildland Fire, 2011
In the present work, post-burning soil N2O fluxes and related microbial processes were investigated in a Mediterranean shrubland subjected to experimental fires. Nine plots were selected, of which three were used as controls, three were burned with low-intensity fire and three with higher intensity fire.
