However, existing studies focus on temperate forest (Fukuda et al., 2003; Kaipainen et al. 2004).
The results focus on temperate climates and were derived using Dutch climate conditions.
Research into the effects of erosion on productivity in the United States has mainly focused on temperate, arable croplands.
Much carbon cycle research has focused on temperate and tropical forests whereas savannas have been less frequently studied [1].
So far, studies addressing the dynamics of labile C and N have mainly focused on temperate forests, but the potential contribution of subtropical primary forest soils to C and N loadings is still poorly known.
Previous studies focussing on temperate natural forests and forest plantations (Iio et al. 2014) and tropical forests in East Africa (Pfeifer et al. 2014) have found a decline in canopy LAI in regions with very high levels of rainfall and water availability.
Most studies have focused on temperate parts of the country, where the use of molecular approaches have already revealed the presence of Bradyrhizobium, Ensifer (formerly Sinorhizobium), Mesorhizobium and Rhizobium genera of legume root-nodule bacteria.
In forest genetics, most efforts so far have focused on temperate and boreal tree species.
Initial interest in the effects of these oscillations largely focused on temperate species within Europe [ 2].
Much carbon cycle research has focused on temperate and tropical forests whereas savannas have been less frequently studied [ 1].
