 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
• An increase in both mean annual temperature and mean annual precipitation 
• An increase in the total annual hours of sunlight
• The invasion of exotic species
