we created a boosted regression tree (BRT) model which uses a combination of boosting, a technique used to improve model accuracy by combining many simple models iteratively to reduce predictive error, and regression trees, models in which repeated binary splits in predictors classify a response50...
Nitrous oxide (N2O) is a climate-active gas with emissions predicted to increase due to agricultural intensification. Microbial reduction of N2O to dinitrogen (N2) is the major consumption process but microbial N2O reduction under acidic conditions is co
MULTIPURPOSE treesCONIFERSSOIL profilesTOPSOILPLANT nutrientsWe explored tree species diversity effects on soil C stock, C/N ratio, and pH as compared with effects of tree species identity. We sampled forest floors and mineral soil (0-40 cm) in a diversity gradient of 1-5 ...

Even models with relaxed assumptions on error distribution such as random forest (RF) or gradient boosted trees fail to predict the original distribution (Fig. 2). Neglecting bimodality may result in maps with unimodal distributions (Fig. 2) with a large number of predictions in a soil pH ...
