Distribution of black carbon in Ponderosa pine litter

Interactive Effects of O3 and CO2 on the Ponderosa Pine Plant/Litter/Soil System

Soil pH trends in a sagebrush meadow and Ponderosa pine ecosystem

1. The acidification effect of Ponderosa pine (Pinus ponderosa) needles on soil pH was tested by sampling and measuring pH of soil in areas with ponderosa pine needle litter and without. 2. A total of three depth classes for five samples in each category of pine needles present and absent were collected and analyzed. 3. Statistical analysis of pH data did not indicate statistically significant ...

Distribution of black carbon in ponderosa pine forest floor and soils following the High Park wildfire

Biomass burning produces black carbon (BC), effectively transferring a fraction of the biomass C from an actively cycling pool to a passive C pool, which may be stored in the soil. Yet the timescales and mechanisms for incorporation of BC into the soil profile are not well understood. The High Park fire (HPF), which occurred in northwestern Colorado in the summer of 2012, provided an opportunit...

Interactive comment on “Distribution of black carbon in Ponderosa pine litter and soils following the High Park wildfire” by C. M. Boot et al

Dear Claudia et al. We are happy to see that our method development was put to good use. The large dataset that you generated using the BC marker method is impressive. Moreover, the finding that the majority of post-fire BC persists in the litter and is probably easily transported elsewhere before incorporation into the soil could be of high interest to the BC community. We have a few technical...

Climate change and fire effects on a prairie–woodland ecotone: projecting species range shifts with a dynamic global vegetation model

Large shifts in species ranges have been predicted under future climate scenarios based primarily on niche-based species distribution models. However, the mechanisms that would cause such shifts are uncertain. Natural and anthropogenic fires have shaped the distributions of many plant species, but their effects have seldom been included in future projections of species ranges. Here, we examine ...
