Fire
Bahre
From a Pacific Historical Review ... '..., it has long been presumed that changes in the region's climate have also contributed to vegetation change. Geographer Conrad Bahre now challenges the view that these vegetation changes are due to climatic…

Northern peatlands: role in the carbon cycle and probable responses to climatic warming
Gorham
Boreal and subarctic peatlands comprise a carbon pool of 455 Pg that has accumulated during the postglacial period at an average net rate of 0.096 Pg/yr (1 Pg = 10'5 g). Using Clymo's (1984) model, the current rate is estimated at 0.076 Pg/yr.…

Fossil fuel and biomass burning effect on climate-heating or cooling?
Kaufman, Fraser, Mahoney
Emission from burning of fossil fuels and biomass ( associated with deforestation ) generates a radiative forcing on the atmosphere and a possible climate change. Emitted trace gases heat the atmosphere through their greenhouse effect, while…

The influence of island and mainland lakeshore landscapes on boreal forest fire regimes
Bergeron
In order to characterize the fires regime of the southern boreal forest and to understand the way in which landscape and fire regime interact, a detailed study of fire history was undertaken in two adjacent contrasting landscapes in northwestern…

A spatial model for studying the effects of climatic change on the structure of landscapes subject to large disturbances
Baker, Egbert, Frazier
Global warming may have many consequences for natural ecosystems, including a change in disturbance regimes. No current model of landscapes subject to disturbance incorporates the effect of climatic change on disturbances on decade to century times…

North American forests and global climate change
Kurz, Sampson
From the text...'In this paper, we will provide a brief overview of the predictions of climatic change and the current understanding of forest response through changes in growth rates, disturbance regimes, and species composition. We will explore…

Determinants of plant distribution
Richardson, Bond
The question of which factors limit the occurrence of a plant species to a particular site is addressed by considering 53 cases in which the distribution of pines (Pinus species: Pinaceae) has changed in the last century. We consider expansions of…

Reduced postfire tree regeneration along a boreal forest - forest-tundra transect in northern Quebec
Sirois, Payett
The large 1950s fires that burned > 5500 km2 of land across a south-to-north climatic gradient in northern Quebec provide an opportunity to evaluate the role of fire in forest-tundra development on a demographic basis. The tree population density…

Biomass fires: preliminary hydrocarbon to carbon monoxide emission ratios
Olbu, Susott, Ward
Due to the increasing concern about global climate change and the realization that biomass fires are a significant source of CO2, CH4, and other greenhouse gases, there is a need to quantify the emissions of these gases from biomass fires. The…

Quantitative assessment of gaseous and condensed phase emissions from open burning of biomass in a combustion wind tunnel
Jenkins, Turn, Williams, Chang, Raabe, Paskind, Teague
Agricultural practices and land use modification were estimated to produce 14% and 9%, respectively, of the total greenhouse gas emissions contributing to global warming in the decade preceding 1990 (Marshall, 1989). Carbon release rates from…
