An important challenge in global-change research is to stimulate short-term transient changes in climate, disturbance regime, and recruitment that drive long-term vegetation distributions. Spatial features (e.g., topographic barriers) and processes,...
Alaska Reference Database
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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

Organic matter is of primary importance to the sustainability of long-term site productivity in forest ecosystems. In boreal forests, organic matter accumulates at the surface as mor humus. This may represent a substantial portion of the total nutrient...

A micro-ecosystem approach was used to study the changes in the edaphic conditions after a medium-intensity ground fire in ca. 120 ha of larch (Larix gmelinii) forest in Evenkia (N. central Siberia). Data are presented on micro-relief, permafrost,...

The lichen woodland is one of the most important forest ecosystems in North America, dominating the central part of the boreal forest. The southernmost lichen woodland is paradoxically in the heart of the southern boreal forest. This distribution...

The nonvascular (lichens and bryophytes) and vascular plant composition of the early regenerating vegetation present following wildfires and clear-cut logging has been compared separately in three areas of the black spruce (Picea mariana)/feathermoss (...

Observations show that the amplitude of the annual atmospheric carbon dioxide cycle has increased. Lagged correlations between carbon dioxide, temperature, and vegetation suggest a modulation by ecosystem response, but the mechanisms remain unclear....

Slow growth, maintenance of a high leaf:wood ratio and adoption of a clonal growth habit, more than size per se, may increase the life span in trees species. The longevity of black spruce (Picea mariana (Mill.) BSP.) is increased from 200 to 300 years...

Although plants of Equisetum spp. are generally thought to be of little value to ecosystems, as study of a cold-temperature Alaskan shrub wetland showed that they acquired and cycled phosphorus and other nutrients more efficiently than other plant...

Changes in terrestrial carbon storage in the United States. 1: The roles of agriculture and forestry
Changes in the areas of croplands and pastures, and rates of wood harvest in 7 regions of the USA, including Alaska, were derived from historical statistics for the period 1700-1990. These rates of land-use change were used in a cohort model, together...
