Wildfires are a dominant disturbance to boreal forests, and in North America, they typically cause widespread tree mortality. Forest fire burn severity is often measured at a plot scale using the Composite Burn Index (CBI), which was originally developed as a means of assigning severity levels to the Normalized Burn Ratio (NBR) computed from Landsat satellite imagery. Our study investigated the potential to map biophysical indicators of burn severity (residual green vegetation and charred organic...
When to salvage burned black spruce and jack pine? Is biomass greater in mixed stands? Is the boreal forest still a carbon sink? Forecasting wood harvesting in private forests Albedo and climate change Poplars fight back against leaf rust

Surface albedo, the fraction of reflected to total incoming solar radiation at the surface, is a property that may be affected by activities related to the extraction or production of biomass. The amplitude of surface albedo changes, and the radiative forcing generated by such changes, may be important relative to other radiative forcing components linked to bioenergy production, with potential positive or negative effects on the net climate footprint of bioenergy. This report presents an overview...
Abstract Brassica vegetables are a source of many biologically active compounds, including glucosinolates (GLS). At present, GLS attract a special attention because of their healthy properties. Four Brassica vegetables: cauliflower, Romanesco-type cauliflower, Brussels sprouts, and broccoli were examined. Analyses of GLS were done in raw, sous-vide cooked, traditionally cooked, and steamed vegetables as well as in samples stored for 5 days at 2 ± 1 °C. In the examined vegetables, 9 GLS were identified....
Mixed forest of Douglas-fir and beech has been suggested as one of the possible future forest types in Northwest Europe but the effects of this mixed forest on soil properties relative to monoculture stands are unknown. In a transboundary investigation of adjacent common garden Douglas-fir and beech stands, we determined the effects on topsoil properties. However, responses of C and N stocks, the C/N ratio and pH were site- and soil layer-specific and were mainly single-sided and without synergistic...
During the history of the Forest Service, human activity has been the dominant influence on climate and the environment; the time being called the Anthropocene. As we look ahead and strive to continue our mission of sustaining the health, diversity, and productivity of the Nation’s forests and grasslands to meet our current and future needs, we must be more flexible to focus our actions to better meet the contemporary conservation challenges now and ahead. During this era of intense human activity,...
