It's not easy being brownish-green

Sorites dominicensis is a common epiphytic foraminifera living throughout the Carribean and South Florida, and is commonly found living on turtle grass, Thalassia Testudinum. S. dominicensis plays host to algal symbionts related to those found in coral. Estimates for the numbers in these symbiotic populations are few, of limited scale, and vary widely. In this thesis we performed a large scale survey of the populations of algal symbionts living within the S. dominicensis population of Jupiter Sound. We then used this data to propose a linear model for the relationship between foraminiferal size and endosymbiont population, and to suggest explanations for the variability seen in the Jupiter Sound population.
