flowers agreed with the description of flowers given for ff. isrightii in den 

 Hartog (1970) and since leaf tip morphology varied from bldenate to tridentate 

 in clonal material, it is concluded that this material is E. umightii- It is 

 also possible that all Halodule in the Gulf of Mexico is E, wvightii- The 

 authors question the practice of creating new species in the genus Halodule 

 based solely on whether vegetative leaf tips are bidentate or tridentate.

 Britain," Aquaoulture, Vol. 4, No. 2, Oct. 1974, pp. 185-198. 



Zostera noltii and Zosteva rmvtna var. angustifolia turfs have been 

 transplanted on sheltered estuarine mudflats in carefully selected areas in 

 Norfolk and Suffolk, Great Britain. Transplanting with turfs can be done on 

 suitable mudflats where mud surface changes in level of at least +7 or +3 

 centimeters per week occur. Growth is favored in areas where a close balance 

 between erosion and accretion occurs. Field scale transplanting of Z. noltii 

 appears feasible in areas approaching 1 hectare in size at a cost of about 

 $1,000 per hectare (1973 prices).

 for Transplanted Portions of Eelgrass (Zostera marina)," M.S. Thesis, 

 Adelphi University, Garden City, New York, 1976. 



Comparison was made of three transplant techniques for eelgrass (ZostervL 

 marina). More than 2,000 plug parts was planted. Survival was technique- 

 dependent and varied from 100 percent for plugs to 36 percent for individual 

 shoots, after 2 months. Miniplugs (survival rate of 71 percent) were best 

 because of ease in harvesting, transporting, and planting. Large initial 

 transport size resulted in greater production of material per unit time. 

 Treatment of single shoots with the hormone, naphthalene acetic acid, was not 

 advantageous. The use of a slow-release fertilizer resulted in greater dry 

 weight values for the shoot and rhizome material. Transplants also showed a 

 difference in growth response once removed from the established community* 

 Transplant success can be achieved without anchoring devices. Areas with 

 shifting sediments and current velocities approaching 1 knot prevent survival 

 beyond 4 months.

 Plant," Marine Pollution Bulletin, Vol. 2, No. 6, June 1971, pp. 87-90. 



Damage to the biota of Biscayne Bay by the heated effluent of a power- 

 plant is demonstrated. Algae and seagrasses were replaced by blue-green 

 filamentous algal mats; seasonal recovery was slow and the affected areas 

 contained fewer kinds and smaller numbers of animals. Increased temperature 

 was the chief cause.

 ceedings of the First Annual Conference on Restoration of Coastal Vege- 

 tation in Florida, Hillsborough Community College Environmental Study 

 Center, Tampa, Fla., May 1974, pp. 21-26. 



Four species of seagrasses (Vallisneria amerioana, Ruppia maritima, 

 Ealodule wrightii, and Thalassia testudinum) were planted in three parts of 

 Escambia Bay. The outcome of the project is not given. Future experimental 

 trials of artificial seaweed are described.
