In tide pool A, the amounts of organisms present, especially the Enteromorpha, Chondrus crispus, and L. littorea did not fluctuate much. As was predicted in Lubchenko's paper the abundance of organisms remained constant through the two months that I observed them for. In tide pool A, "Chondrus abundance remained high throughout this monitoring period; Enteromorpha and other ephemeral algae were present but never abundant. Below is a graph that conveys the distribution of Enteromorpha, Chondrus crispus, and L. littorea.
In tide pool B, where there was an abundance of Chondrus crispus, few Enteromorpha, along with the removed L. littorea, there was a problem that we didn't think we would encounter. Lubchenko's experimental report suggests that with the removal of L. littorea, Enteromorpha would increase in mass and would definitely take over in density in tide pool B. What I did not think of encountering was the reintroduction of L. littorea's in the tide pool. When I came back a month after, there were new L. littorea's in the tide pool. So, I concluded that due to the reintroduction of the L. littorea's in the tide pool, it is the reason why the Enteromorpha did not grow. They were eaten by the L. littorea's. Below is the graph of the actions of the organisms in tide pool B.
In tide pool C Enteromorpha was prevailent and the Chondrus crispus was scarce. Also there were few L. littorea's in this tide pool and I reintroduced the removed L. littorea's from tide pool B into tide pool C. In contrast to tide pool B, tide pool C received the same experimental results as in Lubchenko's tide pool. Due to the preferred food source of L. littorea's, Enteromorpha decreased in mass and density in tide pool C while the mass and density of Chondrus crispus increased. Below is the graph for tide pool c.
Below are the before and after pictures of tide pool A, B, and C. Tide Pool A
I did not find the need to take a before and after picture of Tide pool A because it did not change much. Tide Pool B

Before picture of Tide Pool C. You can observe the abundance of E. intestinalis.
After picture of Tide Pool C. Now, you can observe the decrease of E. intestinalis.
