Traveling southward from the Arctic regions of Canada to the tropics of Panama, one passes through several biomes - tundra, coniferous forest, temperate deciduous forest, and tropical rain forest. This pattern of change in vegetation is primarily the result of

• primary and secondary succession

• the invasion of exotic species

• an increase in mean annual temperature and a decrease in mean annual precipitation

• an increase in both mean annual temperature and mean annual precipitation
