The Last Stand

This is the last week for the existence of my MA. Sadly, not much has changed from last week. Diatoms are still the majority organism in the MA, and there are still next to no Actinosphaerium. The Euplotes, however, are starting to re-emerge, and almost equal the number of Lecane rotifers and Tachysomas. A few more Coleps have started to appear as well, and the Nostoc cyanobacteria have multiplied in large numbers.

There were only two new features to the MA this week: Nematodes and Cinetochilum. I found two Nematodes, and after a few minutes we discovered that what I thought to be a Euplote was, in fact, a Cinetochilium. Other than that, and the regular growth of algae and plant life, nothing extremely exciting was evident in the MA this week. So we end; on a calm, successful note with a variety of life forms discovered and extinguished, all in 5 weeks.

P.s. I have also uploaded pictures for week 1, and edited last week's post for more detailed content.

Rebirth?

In great opposition to last week, the Actinosphaerium and Euplotes have become almost non-existent (I only managed to find one Actinosphaerium). On the other hand, everything else seems to be flourishing. There has been a mass influx of diatoms, vorticella, amoebas, and cyanobacteria. Along with this influx, I saw three new organisms: Coleps, Nostoc (cyanobacteria), and Oscillatory Cyanobacteria. All of these are pictured below, and I am looking forward to seeing if they stick around, or if they mass like the Actinosphaerium and Diatoms.

Until next week,
