Biogeographical regions have boundaries that may be drawn by geological barriers such as mountains or rivers that prevent the organisms from either side from intermixing. These regions differ from biomes in the sense that adjacent biogeographical regions may experience similar amounts of rainfall, exist at the same altitudes or feature some similar organisms. In contrast, biomes are separated from each other very distinctly based on environmental factors such as rainfall and temperature.
