Amongst the disastrous effects of the 1997-98 ENSO I have found the
"Sea urchins eroded disturbed coral colonies at rates that exceed
carbonate production, potentially resulting in the elimination of
existing reef buildups"
My question is how sea-urchins erosion can be best assessed?
Mokady et al. 1996 (Biol Bull, 190(3):367-372), suggest
quantification of CaCO3 fecal pellets contents + total gut contents.
Any other suggestions? I would appreciate everything you can track
