An Aging and Fading Biome

[Don Schaeffer]

I've been keeping these mudpuddle samples for quite some time, many months. At first the water samples contained larger, more conventional microbes. But these samples have been changing quickly of late. Clearly I have to begin new biomes that will contain more conventional protists. These samples are shifting more to bacteria and more or less stationary organisms. The conventional food supply gets used up and the rarer and smaller organisms remain. It is clearly a different biology. I found this process to happen in a number of biomes.
