Aiptasia and Cold Shock
  • After a cold shock, Zoox density will decrease
    after re-warmed to ambient temperatures.
  • The lower the temperature during the cold shocks,
    the lower the Zoox density after re-warmth to
    ambient temp.
  • In conducting the cold shocks, a temperature will
    be reached where no additional Zoox loss will
    occur.

Methods
  • We labeled four independent tubes and placed
    Aiptasia and water within each of those tubes and
    then placed the tubes in a closed container
    containing ice with a thermometer simultaneously
    checking the temperature.
  • We measured the grams of Aiptasia within each
    tube.
  • Every fifteen minutes, beginning at time equals
    zero, we removed a tube, placed the tube outside
    until it went back up to ambient temperature, and
    then measured Zoox density.

Zoox Density of Tubes (1-4)
  • Tube 1 113.9 x 106 Zoox/g wet weight.
  • Tube 2 33.8x106 Zoox/g wet weight
  • Tube 3 34.5 x 106 Zoox/g wet weight
  • Tube 4 32.7 x 106 Zoox/g wet weight

An error..... how? Im perfect!
  • As demonstrated by our data, it appears that
    their was a big gap in Zoox density from the
    first tube to the others.
  • The similar measurements in Zoox density in tubes
    2-4 indicate to us that once a certain
    temperature is achieved (around 2 degrees
    Celsius) no additional Zoox loss will occur.

7
Finally.
  • We will continue to replicate our experiment and
    hopefully well get a constant rate of Zoox loss
    along with a constant temperature level in which
    no additional Zoox loss will occur.
