Microscopic life is usually very similar from one region to another, provided the conditions are similar. However, this limits the sorts of things you can find in any one place. The photos here are mainly from around Calgary, Canada in the northern prairie, which is home to a number of small rivers and creeks.
The weather here is temperate but cool, with intermittent freezing in the spring and fall. Particularly important is that the water here is all very hard, i.e. high in calcium, so many kinds that prefer acidic water will not occur, such as most desmids. Needless to say there is also no tropical or marine life.
Most of the samples were taken home in a clear container and examined for a few days, after which the composition begins changing and they are returned. The following pages give some more notes about where they were from and what was in each, along with many additional images.

I have been using simple light microscopes and Canon cameras, which are good at low-level light and can be attached to the eyepiece via an adaptor. Auto ISO is sometimes a useful feature to avoid changing settings for different magnifications, and video can help capture faster protozoans and animals.
The images have been adjusted for brightness, contrast, and sometimes colour. In addition, the red, green, and blue layers have been lined up to correct for chromatic aberration, and in a few cases several images have been combined together. Otherwise they are more or less unedited.
