  •  Wetland critters is a great idea. (3+ / 0-)

    It helps to concentrate the water down, or find a spot where stuff has settled or accumulated. Sometimes things get trapped within a mass of detritus or roots so a handful of that swished around in a small amount of the wetland water could free those up. Phytoplankton that doesn't swim will settle to the bottom in a very still sample, which you can carefully pipette up.

    I haven't looked at freshwater samples in quite a while but we have wetlands here too. Let's see what we find and compare!

    Aquatic micro-populations are quite responsive to environmental conditions like light, temp. Valuable  phenology markers I'd think. Those date stamps on your micro photos are a great tool.

    •  Thanks for the tips, OD. (1+ / 0-)

      I took air and water temps when I collected the first sample last week. Will collect again on Monday.

      In the meantime, pollen is way cool stuff. Know your enemy... Seems as if cottonwood pollen is everywhere right now.

      Am just beginning to figure out how to use this new tool. Found the date/time stamp yesterday, and really need to work out a way to standardize how I'm looking at stuff. I may need also to check UW surplus for disposable pipettes, and maybe a micro-centrifuge....
