Although time consuming would it have been better to analyze trace elemental concentrations yourself rather than getting averages from a book or previous studies? I thought that it may play a larger than minimal role due to variations in those concentrations from conservative/non conservative metal distributions.
Excuse my ignorance on this next question, but keeping in mind the changes in local SW concentrations of these trace metals how much of a factor do you see in having an organism (if regional) from the East coast such as the urchins peforming in SW from the Long Beach area. Surely the test performance would have proved better if in NSW from the area in which the urchins were collected would they not?
How much greater would you expect the trace metal concentrations to be considering horizontal transport and land based runoff when assessing East and West coast concentrations? Is this a valid factor?
Thank you for your work and contribution to the science and the hobby.
