The Alaska Reference Database originated as the standalone Alaska Fire Effects Reference Database, a ProCite reference database maintained by former BLM-Alaska Fire Service Fire Ecologist Randi Jandt. It was expanded under a Joint Fire Science Program grant for the FIREHouse project (The Northwest and Alaska Fire Research Clearinghouse). It is now maintained by the Alaska Fire Science Consortium and FRAMES, and is hosted through the FRAMES Resource Catalog. The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

1 The effects of catchment fire on lake Pieni Majaslampi are examined by means of geochemical, charcoal, pollen, and diatom analyses of surface sediments. Particular emphasis is paid to pH responses in this naturally acid, weakly buffered, small-catchment lake. 2 An increase of…

This article explores the evidence for monoterpenes to alter rates of nutrient cycling, with particular emphasis on the nitrogen (N) cycle, from an ecosystem perspective. The general N cycle is reviewed and particular processes are noted where monoterpenes could exert control.…

Global annual NO emissions from soil are of the order of 10 Tg NO-N. This is about half the amount fossil fuel combustion processes contribute to the annual global NOx budget. Reducing the emissions of soil derived NOx requires an understanding of the source of the flux and the…

Near Kamloops in the British Columbia interior, a series of small plots were control-burned during the summer of 1977 after detailed botanical assay. Fire parameters were recorded, and soil and vegetation responses to burning were measured in detail for 3 years after the fires.…

Sructural changes in lignocellulosic biomass heated under conitions comparable to those encountered in several types of natural or planned burnings have been studied by solid-state 13C- and 15N-CPMAS NMR spectroscopy of 15N-MNR spectra of biomass subjected to severe heating…

In previous communications it has been shown that soils heated to temperatures from 60° to 150° exhibit an inhibitory effect on the germination of seeds, due to the presence of some toxic substance, which must be a soluble organic, and, probably, nitrogenous, body, for the…

Nitrogen distribution and nitrogen fluxes were studied in a 35-year-old Pinus pinea L. stand growing on a coastal sand site of the French Mediterranean. The amounts of nitrogen in the aerial and root biomass (301 kg ha-1) in the litter layer (498 kg ha-1) and in the first metre…

Grassland communities dominated by Festuca scabrella or by Stipa curtiseta and Agropyron dasystachyum were burned experimentally in spring or autumn. Forb, shrub and graminoid biomasses were greater in the unburned Festuca community than in the Stipa-Agropyron type. Spring and…

'Two studies were undertaken. An initial study in 1974 produced results that indicated significant losses of nitrogen and some other elements. The study was repeated 1981 as a check on the results of the 1974 burn, and to provide an assessment of the methods used in the first…

'Fires are natural in boreal coniferous forest ecosystems, occuring every 100-200 years. Burning of the humus and forest vegetation (mainly spruce and understory) raises the pH of the humus of the podzolic soil and leads to new succession of the forest plant community. The…

We present estimates of nitrogen oxide (NOx) emission from worldwide biomass burning totaling ~13 Tg N yr-1 on a 1 degree longitude by 1 degree latitude grid. Roughly 80 percent of these emissions occur in the zone from 25N to 25 degrees S. The inventory presented here is…

Prescribed burns usually have minimal hydrologic impact on watersheds because the surface vegetation, litter, and forest floor is only partially burned. Wildfire can, however, have a pronounced effect on basic hydrologic processes, leading to the increased sensitivity of the…
