The Ecology Of Drift Algae In The Indian River Lagoon, FloridaLiss, Julie Lynnae 01 January 2004 (has links)
To gain an understanding of the ecology of drift algae in the Indian River Lagoon system along the east coast of central Florida, four questions were addressed: 1) What is the composition and rate of accumulation of drift? 2) How much movement and turnover occurs within drift accumulations? 3) Do growth rates differ for drift versus attached algae? 4) Is there a difference in photosynthetic performance in drift versus attached algal species? Manipulative field and laboratory experiments were conducted to address these questions with the green macroalga Codium decorticatum and the red macroalga Gracilaria tikvahiae. Changes in pigment concentration and biomass were used as indicators of acclimation from an attached to drift state in Gracilaria tikvahiae and Codium decorticatum. Short-term physiological changes as demonstrated by electron transport rate (ETR) were also used as indications of acclimation from an attached to drift state in C. decorticatum. Composition and rate of accumulation of drift varied by season. While both transport and turnover of drift occurred, turnover within drift accumulations occurred at low rates and was significantly lower in the spring during decreased flow rates. There were no significant differences in growth or pigment concentrations in drift versus attached G. tikvahiae or C. decorticatum. In addition, there were no apparent physiological acclimations to a drift state in C. decorticatum.
