How Are Humans Affecting Sea Anemones' Population Distributions?

CSEF · 2014 Environmental Science

Albert J. Barrios · King-Drew Medical Magnet High School, Los Angeles, Los Angeles County

Overview

Objectives/Goals The purpose of this project was to bring awareness to water pollution and the importance of sea anemones in the environment. Methods/Materials Water samples were collected and test for ammonia, pH, and carbon dioxide were conducted. The numbers of sea anemones were counted per measure quadrant. Results It was determined two of the nine sites had higher numbers of sea anemones. These sites had lower measurements of ammonia, as well as high amounts of carbon dioxide. Conclusions/Discussion It is therefore concluded that there is a correlation between the number of sea anemones and the the chemical composition of the water. Specifically, the presence of ammonia and carbon dioxide result in a more neutral pH which is more favorable to the sea anemones.

Summary statement

The study of water chemical contaminants and their effects on sea anemones' population.

Help received
