  3. Ecotone
    the overlap or zone of transition between two plant or animal communities 
  4. Edge effect
    a change in species composition at the boundary between two ecosystems
  5. Forest
    • -trees growing closed together
    • -generally continuous (closed canopy)

  12. Biodiversity "hot spots"
    • -regions with very high natural biodiversity 
    • -Ex. California
  13. Laterites
    highly leached tropical soils
  14. Tropical Seasonal forests
    • -Monsoon forests
    • -semievergreen
    • -partly deciduous forests
    • -heavy rainfall during summer and a distinct dry season during winter
  15. Savanna
    • -tropical grasslands and woodlands
    • -hot, seasonally dry 
    • -scattered trees
  16. Adaptations to the savana environment
    • 1. Xlopodia
    • -woody underground organs
    • 2. Thick bark
    • 3. Sclerophylls
    • -tough leathery leaves
  17. Desertification
    • land degradation in arid regions
    • -Ex. Mali
  18. Bactrian camel
    • -asia
    • -two humps
    • -grows a thick coat of hair each winter. That coat of hair falls off every spring.
  19. Dromedary camel
    • -Arab peninsula
    • -single hump
    • -double row of eyelashes and close nostrils, prevent sand from getting in
