Data and Analysis

   

            The data collected for the different species that were in the vicinity of the anemone was run through a Nominal Logistics Test and an ANOVA test. The results, summarized in Figure 1, showed that there were no significant correlations between the species, the anemones, nor the combination of the species and the anemones. However, the p-value for the test of significance between the species and the anemones was 0.0872 which suggests that there could be a correlation between a specific species and the anemones. More thorough tests need to be conducted, on more data, to determine whether or not there exists a correlation between the species commonly found in Bermuda and anemones.

            The data collected on the dimensions of the anemone was run through several regression tests in order to determine if there was a correlation between any of the parts of the anemones. As can be seen in Figure 2, all of the p-values from the tests show that there are significant correlations between the anatomical shape of the anemone. The oral disc diameter has a correlation with the length of the tentacles. Also there was a significant correlation between the lengths of the tentacles and with both the diameter of the oral disc and the base diameter of the tentacle. All of these results make logical sense. If the body of the anemone is bigger then it is expected that the tentacles would be longer. Same principal applies for the length of the tentacles and the base diameter of the tentacle. However the regression wasn't significant so no dimensions could be predicted with significant accuracy.

               The density of the anemones in Whale Bone Bay was found to be 0.01 anemones per square meter, or one anemone in a 100 meter squared area. This means that if a 10x10m quadrat or a circle of radius 5.64m was randomly placed in Whale Bone Bay there would only be 1 anemone in the designated area. The density suggests that the anemones are widely dispersed, however when the data was being collected most of the areas that contained anemones, contained more that one anemone. In the data collection there were a total of seven areas that contained anemones and only three of those contained single anemones. Thus the density is just a rough estimate for the total amount of anemones that would be expected in an area, but not useful to describe the distribution of the anemones. The area of Whale Bone Bay can be estimated by a circle with readius 102m, and by extraplating the density, 316 anenomes would be expected to be found in the bay.
