Stephanie Lennon Keystone Predator Post-Lab Assignment Section 2 April 21, 2010 Species Reintroduction 1. When we removed starfish from the community in the lab, the mussel population grew enormously. The starfish eat Mussels mainly, along with Chiton and Goose Neck Barnacle. When there were no starfish, the mussel population had no predators to be eating them, meaning they would continue to grow in population without anything stopping them. The mussels also eat five species living in that community (Acorn Barnacle, Nori Seaweed, Coral Weed, Black Pine and Goose Neck Barnacle). With the mussel population growing and their diet being most of the community, it was easy for the mussels to take over the community. When we reintroduce starfish into the population, they will start to regulate the mussel population, allowing the other species to reproduce and even out again. Biocontrol Before introducing this new species of barnacles into the environment, one should

Unformatted text preview: look up what this species eats and or attacks. If the barnacle is going to hurt the other populations of species in the area and is going to decrease their population by a lot, then it would not be a good idea to have these barnacles introduced into the community. Their purpose is to decrease the number of green crabs in the area so that the other species can prosper and reproduce like they would in a community without the green crabs in it. We know that the barnacle enters the crab by a joint and makes its way to the reproductive area. In a female crab, the barnacle implants its self into the sac where the eggs are. In a male crab, the barnacle sterilizes the crab and makes it look and act like a female crab. Seeing that it does this to crabs, and crabs only, we know that it will not affect the other creatures living in the community and will allow them to reproduce and regain their stability in the environment....
