Indian and Northern Affairs.] -- This study summarizes the microclimatic effects of burning of open subarctic woodland in terms of soil temperature, soil moisture, radiation, evaporation and evapotranspiration. Tundra, a major zone of treeless level or rolling ground found in cold regions, mostly north of the Arctic Circle (Arctic tundra) or above the timberline on high mountains (alpine tundra).
Tundra is known for large stretches of bare ground and rock and for patchy mantles of low vegetation such as mosses, lichens, herbs, and small shrubs. Tundra ecosystems are found in the arctic and on alpine zones of mountains.
Arctic tundra is relatively homogeneous in terms of vegetation structure, with low biodiversity due to its recent glacial history, while alpine tundra is much more diverse, with higher biodiversity mostly because of its fragmentation on isolated mountains.
Tundra is. Fire is a dynamic ecosystem process, generally predictable but uncertain in its timing and occurrence on landscapes .It is an integral component of most wildland forest ecosystems as well as wild and managed grasslands ().It has been a factor in shaping plant communities for over million years, as long as vegetation and lightning have existed on earth [2, 3, 4, 5].

Boreal Forest Fire Regimes And Climate Change. predict the effects of climate change on tundra fire regimes, it is critical to have detailed knowledge of the natural frequency and extent of. Climate (from Ancient Greek klima, meaning inclination) is commonly defined as the weather averaged over a long period.
The standard averaging period is 30 years, but other periods may be used depending on the purpose. Climate also includes statistics other than the average, such as the magnitudes of day-to-day or year-to-year variations.
This book explains the structure and functioning of terrestrial ecosystems, using examples ranging from the Arctic to the tropics to demonstrate how they react under differing conditions.
This knowledge is developed into a set of principles that can be used as starting points for analysing questions about ecosystem by: We used a literature review to examine responses across disturbance types (i.e.
fire, warming, nutrient addition, drought) and ecosystems (tundra, meadow, forest, peatland). We included studies that examined moss community responses to disturbance as the change in total species richness, total abundance (% cover of moss), and/or net growth by: Brown, James K.; Smith, Jane Kapler, eds.

Post-fire forest regeneration is strongly influenced by abiotic and biotic heterogeneity in the pre- and post-fire environments, including fire regimes, species characteristics, landforms, hydrology, regional climate, and soil properties.
Assessing these drivers is key to understanding the long-term effects of fire disturbances on forest by: 6. The emerging predominance of western white pine on MD-GNP, especially in mid- and high-elevation stands, resulted from several interacting factors: (1) survival —fires increased in warming climates and with lower levels of higher suppression, and western white pine is better able to survive fire than many other conifer species in the Cited by: White spruce establishment was limited after a "severe" wildfire in the black spruce-white spruce forest-tundra ecotone northeast of Inuvik, Northwest Territories and none of the white spruce that established in the first 5 years after the fire in the acre ( ha) study area survived.
Many physical, chemical, mineralogical, and biological soil properties can be affected by forest fires. The effects are chiefly a result of burn severity, which consists of peak temperatures and.
Microclimate. Even in the complete absence of vegetation, major climatic forces, or macroclimates, are expressed differently at a very local spatial level, which has resulted in the recognition of so-calledthe surface of the ground undergoes the greatest daily variation in temperature, and daily thermal flux is progressively reduced with both increasing distance above and.
Boreal forest is a conifer or conifer-hardwood forest type occurring on moist to dry sites characterized by species dominant in the Canadian boreal forest. It typically occupies upland sites along shores of the Great Lakes, on islands in the Great Lakes, and locally inland.
Modeling: Several fire effects, fuel, and fire behavior models applicable to whitebark pine ecosystems are available at McKenzie and others [ ] provide a model for predicting coarse-scale fire effects in whitebark pine and other potential natural vegetation types of the Columbia River Basin.
These same principles (differences in microclimate and quality of above- and belowground C inputs) also determine the overall effect of vegetation shifts and land use changes in alpine ecosystems, with the encroachment or planting of trees in mountain meadows or tundra systems often resulting in a net loss of soil C.
Detecting the origin of SOC. Sedimentary evidence suggests that O 2 levels have varied greatly in the Phanerozoic. Fire is sensitive to O effects of fire on modern ecosystem structure and on plant morphology are reviewed and used as a basis for predicting how the fossil record might reflect high O 2 fire regimes.
It is observed that fire is a strong agent of natural selection, and that if O 2 has been unstable, the Cited by: - both consider relationships between organisms and environment - bio-geography emphasizes spatial distributions (local and regional scales) and how these change over time (temporal) - focus of bio-geography is primarily on biological/ physical processes but human interactions with the biophysical environment are also addressed.
