Release of mercury from Rocky Mountain forest fires
[1] Concentrations of mercury (Hg) in soil profiles and vegetation were examined in unburned areas and in areas recently burned by wildfires of low, medium, and high fire severities in western Wyoming. Paired unburned and burned sampling sites with similar tree species composition, forest stand age, climate, and geological substrate were studied. Results indicate that Hg release from forest fir...
متن کاملAspen Increase Soil Moisture, Nutrients, Organic Matter and Respiration in Rocky Mountain Forest Communities
Development and change in forest communities are strongly influenced by plant-soil interactions. The primary objective of this paper was to identify how forest soil characteristics vary along gradients of forest community composition in aspen-conifer forests to better understand the relationship between forest vegetation characteristics and soil processes. The study was conducted on the Fishlak...
متن کاملEcological processes dominate the 13C land disequilibrium in a Rocky Mountain subalpine forest
Fossil fuel combustion has increased atmospheric CO2 by≈ 115 μmol mol 1 since 1750 and decreased its carbon isotope composition (δC) by 1.7–2‰ (the C Suess effect). Because carbon is stored in the terrestrial biosphere for decades and longer, the δC of CO2 released by terrestrial ecosystems is expected to differ from the δC of CO2 assimilated by land plants during photosynthesis. This isotopic ...
متن کاملThe impact of fire on the forest and plants diversity in Iranian Oak forest
Fire, as a natural ecological disturbance factor in forest, this study located in the Marivan region, Northern Zagros forest, and western Iranian state of Kurdistan. In each burned and unburned area 30 circle sample plot (1000 m2) were collected by randomized–systematic method in the 100×200 m net (in total 60 plots). In every sample plot the kind of species, number of tree, the heig...
متن کاملMultiple environmental changes drive forest floor vegetation in a temperate mountain forest
Human-induced changes of the environment and their possible impacts on temperate forest understory plant communities have been examined in many studies. However, the relative contribution of individual environmental factors to these changes in the herb layer is still unclear. In this study, we used vegetation survey data covering a time period of 21 years and collected from 143 permanent plots ...
