High phosphate uptake requirements of the scleractinian coral Stylophora pistillata

High phosphate uptake requirements of the scleractinian coral Stylophora pistillata Claire Godinot, Renaud Grover, Denis Allemand, Christine Ferrier-Pagès The Journal of Experimental Biology  2011  214: 2749-2754;  doi: 10.1242/jeb.054239  http://jeb.biologists.org/content/214/16/2749 Also poorly understood in the nutrient balance is phosphate’s role. This sheds light on why zero is not the goal. Addition of ammonium or nitrate (up to 6.0 μmol l–1) did not enhance saturated phosphate […]

Spectrometer

  This is my Project STAR spectrometer.  It was very inexpensive. I  use it for examining the color of different lights inside and outside.  (Don’t look directly at the sun through this device – or anything else!) It works by taking in light via the small opening at the upper-right. The light bounces off the diffraction […]
