Week Four

A group of Philodina sp.
Rainis and Russell 1996, Figure 88.
It is the final week of observation, and things are slowing down in the microaquarium. Some of the decrease in diversity and population could be accounted for by the loss of water (evaporation) and higher organisms on the food chain. I would hypothesize that the Philodina had a significant influence on the foodchain and the present state of the aquarium.I snapped a shot (Figure 1.) of some Philodina congregated around some foliage feeding on random bits of food. Although the Philodina population has exploded, I noticed an increase of Diatoms and Green Algae. The population of Tachysoma has remained steady with just a handful times throughout the entire observation time.
