Document Summary
Biogeography and diversity: study of the spatial and geographical distribution of organisms. Similar appearance and nature of organisms found in geographically different regions link form and function similar types of plant communities in similar climates. Convergent evolution: independent evolution of a similar characteristic in 2 different species not derived from a recent, common ancestor. Biomes: biotic units are classified by predominant plant types there are 9 major terrestrial biomes: Fig 23. 2: temperature and precipitation have an inverse relationship. Fig 23. 6 tropical rainforest: between 10 degrees n and s the mean temperature >18 degrees c minimum monthly precipitation is 60 mm. Tropical savannahs: temperature is >18 degrees c distinct precipitation season soil texture is unique in that is can hold water until the dry season comes. 23. 12 + 23. 13 + 23. 28 (in canada) + 23. 26 + 23. 29a + 23. 30 + 24. 31b + 23. 32 + 23. 33a. Aquatic ecosystems: first, we separate by marine (saltwater) and freshwater then we have subcategories:
