  1. How would synchrony in the timing of oak pollination across multiple species in the same location affect animals living in the oak woodland?
    Synchrony is when pollen release happens at the same time across locations or among species, which causes there to be a good year everywhere or a bad year everywhere; hence affecting animals way of living.
  2. How are coast redwoods able to survive the summer drought characteristics of California's Mediterranean climate?
    The redwoods use fog water; fog reduces the vapor pressure deficit so trees lose less water when they open the pores on their leaves to take up CO2 for photosynthesis.
  3. How does coastal upwelling influence fog formation along the coast?
    Moist ocean air is drawn onto coast by rising air inland because air blows over cold water of california current; air cools and water condenses which then becomes fog
  4. give two examples of chaparral plant adaptations to fire, explaining how they are adaptive.
    an example of chaparral plant adaptation would be the Mariposa Lily; it is a fire stimulated reproduction. Another would be the chamise, it reduces heat gain by having vertically oriented leves and sliver or whitish leaves that reflect the sun.
  5. what is plant adaptation?
    Plant adaptaion is a genetically controlled characteristic or trait that is beneficial to an organism's survival or reproduction, which is then passed on.
  6. where is there multiple "stair steps" (5)
    in Mendocino
  7. Staircase shape results from:
    coastal uplift and changing sea level
  8. (chaparral) Reduce water loss by:
    having small leaves and thick leafe cuticle; example: the chamise
  9. (chaparral) reduce heat gain by:
    vertically oriented leaves, silver or whitish leaves (color reflects the sun)
  10. chaparral regions have....
  11. what is ocean upwelling?
    when the coast brings cold water to surface, making water. (and therefore coastal areas) cooler, and foggy
  12. what does fog do?
    fog reduces vapor pressure deficit so trees lose less water when they open the pores on their leaves to take up CO2 for photosynthesis
  13. what is vapor pressure deficit(VPD)?
    the difference between amount of water in air and amount it can hold when saturated.
  14. what is an example of a fire stimulated reproductiong?
    the mariposa lily, they come out almmost only after fire
  15. what are example of ignition sources?
    lightening, sparks from falling rocks, volcanic activity, and people
  16. Fire requires what three things?
    fuel source, heat, and oxygen; remove one of the three and thre fire can not exist.
  17. What is mutalism?
    interactions betwwen individuals of different species that benefit both partners
