Title: The effects of the cyanobacterium Lyngbya majuscula and artificial shading on the seagrass Halodule wrightii.
Creator: Tiling, Kathryn A., Harriet L. Wilkes Honors College
Abstract/Description: Extensive blooms of the marine cyanobacterium Lyngbya majuscula occurred during 2006 in Halodule wrightii seagrass beds. We examined the effects of L. majuscula blooms on seagrass by removal treatments and assessed if this was primarily an effect of shading by conducting artificial shade treatments. We tested the effects of L. majuscula removal and artificial shading on fifty individual 0.25 m2 experimental seagrass plots infested with L. majuscula in a fully crossed, two-way experiment....
Show moreExtensive blooms of the marine cyanobacterium Lyngbya majuscula occurred during 2006 in Halodule wrightii seagrass beds. We examined the effects of L. majuscula blooms on seagrass by removal treatments and assessed if this was primarily an effect of shading by conducting artificial shade treatments. We tested the effects of L. majuscula removal and artificial shading on fifty individual 0.25 m2 experimental seagrass plots infested with L. majuscula in a fully crossed, two-way experiment. Measurements included blade elongation, biomass, and stem density. Blade lengths of H. wrightii were significantly increased by the presence of artificial shading and L. majuscula. L. majuscula removal resulted in increased below ground biomass in shaded plots, suggesting an increase in stores, when possible, for accelerated recovery following a shading event. Adverse L. majuscula effects occurred after declines in bloom biomass indicating that L. majuscula can have a prolonged negative effect on H. wrightii production.

Title: Phosphorus uptake kinetics of the tropical seagrass Thalassia testudinum.
Creator: Gras, Amy Frances, Florida Atlantic University, Koch, Marguerite
Abstract/Description: Recent evidence indicates P-limitation in tropical seagrass beds, but to date no data are available on P kinetics of the dominant tropical seagrass Thalassia testudinum. In this study, T. testudinum leaves and roots exhibited Michaelis-Menten saturation kinetics under high (0.5 to 25 muM SRP) and low (0.5 to 5 muM SRP) P concentrations. Leaf Vmax was similar under light and dark conditions. Root Vmax under the high range was slightly lower (30%) in the dark and 2 to 3-fold lower than leaves...

In this study, T. testudinum leaves and roots exhibited Michaelis-Menten saturation kinetics under high (0.5 to 25 muM SRP) and low (0.5 to 5 muM SRP) P concentrations. Leaf Vmax was similar under light and dark conditions. Root Vmax under the high range was slightly lower (30%) in the dark and 2 to 3-fold lower than leaves in the light and dark. Leaf and root P uptake rates were similar at low substrate concentrations. A two-phase kinetic system appears to be functioning with lower values of leaf Vmax and Km at low P levels, indicating a higher affinity for P by leaves at lower P concentrations. In conclusion, T. testudinum leaf and root tissues may contribute similarly to plant P uptake at low concentrations.

Title: Habitat suitability and population demographics of the seagrass, Thalassia testudinum, in the northeast salt ponds of Key West, Florida.
Creator: Miller, Cheryl L., Florida Atlantic University, Austin, Daniel F.
Abstract/Description: Reconstructive aging techniques were used to construct the age frequency distributions of T. testudinum short shoots in the Salt Ponds of Key West, FL. Median short shoot age was approximately two years. No evidence of sexual reproductive effort was found. A site-specific leaf emergence rate was not used, which may have contributed error in the reconstructive technique. Gradients in salinity, phosphorous availability, community composition, and leaf width were observed along the water flow...
Show moreReconstructive aging techniques were used to construct the age frequency distributions of T. testudinum short shoots in the Salt Ponds of Key West, FL. Median short shoot age was approximately two years. No evidence of sexual reproductive effort was found. A site-specific leaf emergence rate was not used, which may have contributed error in the reconstructive technique. Gradients in salinity, phosphorous availability, community composition, and leaf width were observed along the water flow pathway through the ponds. Populations of short shoots more distal from the tidal source exhibited an older age structure reflecting higher salinity, temperature, and dissolved oxygen stresses. Populations closest to apparent sources of nutrient enrichment were skewed toward young individuals. A significant positive relationship between increasing short shoot mortality and recruitment was identified. A significant correlation between low phosphorous availability and narrow leaf width was observed, and a positive relationship between phosphorous availability and recruitment was suggested.

Title: Examination of the Use of Floating Individuals of Halodule wrightii (Ascherson, 1868) for Restoration.
Creator: Berninger, Jacob J., Hanisak, M. Dennis, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The goal of this study was to develop an alternative approach to typical seagrass transplantation techniques that damage the donor bed. Floating individuals of Halodule wrightii were collected in the Indian River Lagoon (IRL), Florida, during fall of 2013 and spring of 2014, with the fall collection planted in outdoor tanks. Only 25% of individuals collected in the fall survived the winter in the tanks. Individuals from both collections were deployed onto biodegradable mats in a capped dredge...

Floating individuals of Halodule wrightii were collected in the Indian River Lagoon (IRL), Florida, during fall of 2013 and spring of 2014, with the fall collection planted in outdoor tanks. Only 25% of individuals collected in the fall survived the winter in the tanks. Individuals from both collections were deployed onto biodegradable mats in a capped dredge hole in the IRL in March, 2014. Approximately 66% of the mats survived the six-month experiment, and the area covered by seagrass quadrupled. Growth in shoot count, average height, horizontal spread, and biomass was similar for both fall and spring treatments. Thus, time and effort of overwintering had no benefit over spring harvesting. The use of floating individuals can provide a more practical, environmentally friendly alternative to traditional transplanting for seagrass re storation.
