Microlife: Dirt puddle by park

Jul 6-11, 2013

The day before this was taken there was a thunderstorm, interrupting a week of mostly hot weather and followed by some light rain. There were only a few puddles; this was from a larger one at the edge of a park where several tire tracks had scooped out a dirt basin, taken around a small plant growing there.

Puddle

The water was full of green flagellates, especially Pandorina, various Euglena, and Gonium as well as smaller single-celled types. These became less common after a few days, though when the container was raised to get more sunlight Euglena were soon plentiful in the corner towards it.

Drops from both the surface and mud also often held fast Polyarthra, both with and without attached eggs. Some other common sorts were various Phyllopharyngea, Paramecium, and bdelloids, as well as tube-building ciliates including both long branching Chaetospira and single Stichotricha.
