Pitt Labs @ Pymatuning

This morning we went to the University of Pittsburgh laboratory located at Pymatuning.  There were a ton of kiddie pools and cattle feeders in which the scientists would fill with water and use to grow whatever they need for their experiments, typically tadpoles or plants.  Then there was a small building that actually held the lab equipment.  Most of the researchers were working on a joint project with scientists in Oregon involving a disease that is killing frogs in Oregon.  The egg masses were shipped from Oregon and have been grown in the pools.  Now the researchers are working with the metamorphlings and pesticides in order to find out if the use of pesticides is weakening the frog's immune system.  Later on we were allowed to feed some tadpoles to a drangonfly nymph.
