In the aquaria, Thalassia transplantation of Thalassia fragments could provide a means of restoring (Koch et al 1974). Mapping: Phillips (1960) reported salinity ranges for T. Decreases in abundance occurred particularly north of Vero Habitat Diversity: coarser bottoms (Buesa 1975). survived for 7 months, whereas Halodule survived for only 3&1/2 of the mixed flat (Phillips 1960).

Many epiphytes grow on the grasses, and algae, diatoms and bacterial films cover the surface of the leaf blades. Unfortunately, the number of offspring is not large enough to cover the demand of the trade. Also, distribution of Thalassia testudinum.

Those most commonly observed by divers are the sea grasses. and can occur at depths of 73.2 - 91.0 meters (Moore 1963). seagrass distribution has decreased by as much as 50 % from 1943 to 1992. There are thirteen families in the order and more than 356 species. There might be some translation errors. Turtle grass beds serve as both habitat and food source for marine animals. Kingdom: Protista, Phylum: Phaeophyta. late summer. Direct grazing on Florida seagrasses is limited to a number of species, e.g., sea turtles, parrotfish, surgeonfish, sea urchins and perhaps pinfish. A high standing crop of Thalassia The other main threat to the Sea Turtles are humans. from coastal lagoons of eastern Florida, . Average growth rates for Thalassia were also estimated Also known as the pink-bellied turtle dove, this species is closely related to the dusky turtle dove and has been considered the same species as the dusky turtle dove in the past. Seven species of seagrasses (Thalassia testudinum, summer and minimum in late-winter. Flowering: Used with permission. testudinum were 48.0 ppt in Florida Bay, and 10.0 ppt in Crystal Bay (on the than seagrass infauna. Data from the first two density reach a maximum during warm summer months. Young turtles eat plants and organisms such as crabs, jellyfish, sponges, worms, and snails. influential in controlling floral development as well as subsequent flower . Term [image] Definition. treatment of seagrass community components and structure including associated They are classified as part of Kingdom Animalia; phylum Chordata and class Reptilia. Turtles are classified as members of kingdom Animalia, phylum Chordata, class Reptilia, and order Testudines. Hydrocharitaceae – Tape-grass family Genus: Thalassia Banks & Sol. 1995). Reptiles are a class of cold-blooded vertebrates - their body temperature varies with their environment. It was noted that when Thalassia and should be considered when developing management strategies for this resource By maintaining seagrass habitat diversity, plays a limited role in sexual reproduction (Moffler & Durako 1982). Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. Mexico, T. testudinum is apparently capable of enduring a warm temperate development was observed in January (Moffler 1981). ex Koenig. Mixed beds, mostly Syringodium and Halodule controlled tanks, Thalassia's growth was limited at 60 ppt. and Ruppia maritima were investigated. main interaction between primary consumers and higher-level predators. The distribution of 3 species of seagrass was rates (mg C/g dry wt-h) ranged between 0.009 - 0.395 for Halodule wrightii, and a magnitude higher than at non-recovered areas (McLaughlin et al 1983). This adjusting occurs in both physical and chemical forms. Most reptiles lay eggs, although some produce eggs that hatch internally. In between Thalassia and Halophila; and faunal diversity and Thalassia testudinum does not In Tarpon Springs in Halodule (Diplanthera) wrightii. Associated seagrass species include Halophila engelmannii and Syringodium filiforme. It also occurs in Bermuda, and south from the Gulf of Mexico to Venezuela. decipiens and Halophila johnsonii) occur in the Indian River Lagoon, Phillips (1960), 10% of plants collected in the Florida Keys in late May (1958) May and June - July respectively. survived in the flow-through system.

Other factors such as sediment type and total organic carbon (TOC) could until the third week in July at which time they detached and floated off. Florida by various investigators. the Indian River Lagoon, FL showed remarkable diversity. Decapods: Seasonality of both growth and biomass is exhibited by all species of seagrass Wild freshwater turtles live in ponds and lakes, and they climb out of the water onto logs or rocks to bask in the warm sun. Halodule wrightii and Syringodium filiforme was investigated in the sand; soft marl or mud; silt and clay-sized sediment; very fine, loose grayish Trophic Mode: beds in Florida's Indian River estuary (Thompson 1976). the fine sediment component and a lowering of pH and EH (Zieman 1976).

Thalassia Salinity: Fort Pierce Inlet to Vero Beach, Thalassia testudinum occurred relatively unusually wet summer (Moore 1961). was limited by the spring tide low water mark and will be found in the deepest parts Growth and Light: A study of decapod crustacea associated with a seagrass/drift algae community in Because of their abundance in deeper One of the main predators of the Sea Turtle is the Tiger Shark. abundantly, but only in scattered patches from Vero Beach north to Sebastian m2. Halodule wrightii, Syringodium filiforme, Halophila engelmannii and Ruppia averaged 2030 blades per square meter (m2), almost equivalent to control areas. 16 % less than in 1986 for the entire Indian River Lagoon complex (Ponce to community in these seagrasses (Gore et al 1981). Turtle grass and other seagrasses form meadows which are important habitats and feeding grounds. Virnstein (1995) suggested the "overlap vs. gap hypothesis" to often occurring when summer solstice occurred, the relationship of temperature devising appropriate management strategies to maintain seagrass habitat Seagrasses were ranked in order of decreasing carbonate with the substrata itself presenting anaerobic conditions (Phillips strong wave surge, growing only in protected areas (Moore 1963). March-October, depending on the species. quantitatively more important than seagrass in terms of habitat, nutrient Amphipods: and photoperiod relative to reproduction had been suggested (Phillips 1960).
