It is a serious interest. Before I got sucked into frogs I frequented
swamps for protozoa. In fact that's how I got sucked in. Saw about the
survey, thought that would be a good way to look in more swamps for
protozoa. My field microscope has not been used in a few years, though
I'm going to get back to that. My primary professional training and long
term interest is aquatic micro ecology. I've been toying with this idea
for a while, though have not done a lot of research yet.
Be glad for any references that might help. I can fit a single protozoa
in a larger volume of water if that's what's necessary. I've even got
the micromanipulators to sort bacteria one at a time. Though it would
sure be nice to do it on a slide where I can watch the animal.
