Maybe I missed it here or on aquatic plants... What is you thesis on?

1)Algae in Floridian springs.
2)Photorespiration in freshwater ecosystems
and 3)Themal cycling flux of substrates in aquatic ecosystems.

That should keep me out of trouble for a while.

As
my boys and I learned, falling off logs is half the fun ;-) Sometimes, I
think when I retire, I'll go back to school ;-)
