Central Eurasian grasslands are referred to as steppes, while African. Community density decreased independently of soil nutrition but significantly related to decreased species richness. Temperate grasslands are somewhat humid, but can also be arid, meaning dry or little moisture in the air. At the higher latitudes of the Southern Ocean they form the main vegetation of subantarctic islands. Tradeoffs and thresholds within the results of nitrogen-addition on bio-diversity and ecosystem functioning: evidence from inner Mongolia Grasslands. Likewise, temperate grasslands may have a scattering of shrubs or trees that blurs their boundaries when they occur adjacent to scrublands or temperate forests. A restricting factor is something that constrains a populations size and slows or stops it from growing.
