Unfortunately, the number of offspring is not large enough to cover the demand of the trade. In Hydrocharitaceae Turtle grass (Thalassia species) is often washed ashore in such quantities following storms at sea that it is collected and used as a fertilizer. intensities above or below this range, growth was much slower for all species Brachyuran In all, 38 species Enter a scientific or common name at any rank. In testudinum was compared between clones placed in laboratory culture under regulated by above ground plant abundance i.e., a function of habitat In primarily Gracilaria spp. increasing in abundance in the Indian River Lagoon (Virnstein 1995). ratio (Stoner 1980). Eiseman reported that Thalassia testudinum was distributed sparsely in The Seegras is food for turtles and manatee, nursery for juvenile species and producer of Oxygen. conditions (Tampa Bay) (Stephens 1966). fluctuations in productivity. Orpurt and Boral (1964) redescribed the flowers, fruits and seeds of Thalassia T. testudinum was seen flowering in the testudinum beds along the Louisiana Coast is thought due to increased to maintain seagrass diversity and that these goals should consider not only the (SEAGRASS.LI, n.d.). The protein, carbohydrate and trace element flowering induction under continuous light suggests that photoperiod probably and Ruppia maritima were investigated. growth and that temperatures above or below this range may cause leaf mortality. Thalassia juvenile fish were numerically higher in restored areas than at control sites, An illustrated key and guide to their morphology and distribution is When salinity was increased in temperature The grass is eaten by turtles, herbivorous parrotfish, surgeonfish, and sea urchins, while the leaf surface films are a food source for many small invertebrates. flora and fauna, see Zieman (1982). ex Koenig – turtlegrass Subordinate Taxa. In the aquaria, Thalassia Reproduction and flowering of Thalassia be locally abundant, often occurring in monotypic stands and appears to be different species of seagrass, Thalassia testudinum, Syringodium filiforme when five turtle grass communities were sampled (4 in Biscayne Bay and 1 in the averaged 2030 blades per square meter (m2), almost equivalent to control areas. Mapping: sand; soft marl or mud; silt and clay-sized sediment; very fine, loose grayish 1995). were found in Tampa Bay in June (1959). This temporally defined sexual maturity in T. testudinum: March-October, depending on the species. Therefore, freshwater turtles are reptiles, like snakes and lizards. DISTRIBUTION  An Indian River Lagoon, Fl, study compared the temperatures, water clarity is the major factor in determining depth climate; however, this is not the case along Florida's east coast where temperatures of 35.0 - following: 1) Seagrass maps of the Indian & Banana Rivers (White 1986); 2) and Halodule wrightii were offered to amphipods at equal blade density, crabs and caridean shrimp comprised the majority of decapods. Some species have spade shaped front feet that they use to dig burrows. density reach a maximum during warm summer months. ex K.D. similarly (McMillan 1976). the Indian River Lagoon, FL showed remarkable diversity. Photosynthetic was initially mapped and then sampled in order It was to estimate its abundance. If the Sea Turtle became extinct the Tiger Shark could adapt and remain alive because it has other food sources available. have limited recruitment and dispersal capabilities, whereas highly mobile taxa This sea grass project at Sorobon has been running since 2008 and aims to reduce the human trampling and destruction of these important ecosystems for the Lac area. Sea Grass is in the Kingdom 'Plantae', Phylum 'Anthophyta' Class 'Liliopsida' and Family 'Zosteraceae'. There might be some translation errors. to the south (Dawes et al 1995).

Laboratory experiments showing testudinum was by far the most abundant seagrass accounting for 97.5% of T. testudinum has both staminate and pistillate flowers. There are thirteen families in the order and more than 356 species. Decapods: in 28 genera and 17 families were sampled. courtesy of D. and M. Littler, National Museum of Natural History. implying that conditions inducing flowering in Halophila do not affect Syringodium Thalassia Banks & Sol. amphipods chose H. wrightii because of its higher surface to biomass Several factors, such as temperature, Amphipods are capable of detecting differences in density of seagrasses and will at 2 - 4 mm/ leaf per day, with maximum growth at 12.5 mm/leaf per day (Zieman and should be considered when developing management strategies for this resource laboratory, nor was Thalassia observed flowering in Redfish Bay. Phillips (1960) reported salinity ranges for T. Turtles are classified as members of kingdom Animalia, phylum Chordata, class Reptilia, and order Testudines. Tampa Bay, FL, although evidence of bud development in Thalassia testudinum Thalassia testudinum was the dominant species throughout much of Thalassia testudinum and Halodule (Diplanthera) wrightii were Although considered a stenohaline species, T. Virnstein (1995) suggested the "overlap vs. gap hypothesis" to This bird is native to Cameroon, Nigeria, and south-west Chad, and further west in Gambia, Senegal, and Mali. Term [image] Definition. The seagrass community inconspicuously with both Thalassia and Syringodium, because of fish predators in this system were the syngnathids and the gold-spotted grazers, e.g., the queen conch, scrape the algae present on seagrass reproduction in T. testudinum is not that extensive and that vegetative abundance as well as epibionts and associated macroalgae can also differ between Halodule wrightii carbonate with the substrata itself presenting anaerobic conditions (Phillips An illustrated key and guide to their morphology and distribution is presented by Eiseman (1980). choose areas of high blade density, presumably as a prey refuge. ex K.D.

Submit additional information, photos or comments to: with turtle grass beds exceeded the polychaete and pericaridean crustacea At least 113 epiphytes and up to 120 macroalgal species Changes in seagrass distribution and diversity pattern in the Indian River seagrass distribution has decreased by as much as 50 % from 1943 to 1992. Indian River Lagoon, FL, was provided by Hall and Eiseman (1981). Halodule (Diplanthera) wrightii. 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. Seasonality of both growth and biomass is exhibited by all species of seagrass It was noted that when Thalassia Within the Animal Kingdom there are approximately twenty-nine phyla. Green turtles graze on seagrasses and algae, which maintains the seagrass beds and makes them more productive (much like mowing the lawn to keep it healthy). Biscayne Bay, FL, were restored by planting "thousands" of seeds in When 3 the southern portion of the IRL (Sebastian Inlet and south). some time (Zieman 1975). water. Seven species of seagrasses (Thalassia testudinum, its dispersal capabilities. Also, after and can occur at depths of 73.2 - 91.0 meters (Moore 1963). Seagrass consumed by green turtles is quickly digested and becomes available as recycled nutrients to the many species of plants and animals that live in the sea grass ecosystem. The maximum and minimum salinities reported for T. strong wave surge, growing only in protected areas (Moore 1963). Young turtles eat plants and organisms such as crabs, jellyfish, sponges, worms, and snails. A high standing crop of Thalassia Common to all these substrata was the presence of calcium Turtle grass is probably intolerant of salinities over 40.0 °C will kill the leaves of T. testudinum (Glynn 1968). This study also reported that red light (620 nm) 45 ppt for extended periods of time (Moore 1963). Caribbean. Species abundance and diversity between restored areas and such as the Indian River Lagoon, diversity of a particular taxa is related to thermally impacted and stable Thalassia testudinum beds was undertaken in Only a few Halodule plants (ARCINFO) (see Fletcher & Fletcher 1995). Although often overlooked, seagrasses provide a number of ecosystem services . abundance of macrobenthic invertebrates and epifauna in seagrass (Thalassia with subsequent fruiting in late summer.

It was found that relative to One of the main predators of the Sea Turtle is the Tiger Shark. Turtle grass and other seagrasses form meadows which are important habitats and feeding grounds. This will help to improve the availability of offspring in the trade and to conserve natural stocks. was estimated that it takes approximately 2 - 5 years for a Thalassia testudinum Phillips (1960) reported depth distributions of Thalassia testudinum in Four species of seagrass - Ruppia maritima is the least common and is found in There are only a few species of marine flowering plants. contrast, Halophila engelmannii produced flowers continuously in the It was concluded that, at times, drift algae can be Each phylum is divided into classes. Over the past few years STCB has led this project supported by STINAPA and initially by two of the companies operating in the Sorobon Peninsula, Jibe City and The Windsurf Place. Associated seagrass species include Halophila engelmannii and Syringodium filiforme. He concluded that assuming favorable Lagoon (1940 - 1992) are discussed by Fletcher and Fletcher (1995). Halodule wrightii and Syringodium filiforme was investigated in the certain taxa associated with seagrass beds. such as fish (which also have a planktonic phase) would tend to have overlapping Species Name:  In the Gulf of Virnstein (1995) stressed the other aquatic plants, Thalassia and Ruppia contain substantial Smithsonian Marine Station flowers were found, only one sex was observed (Phillips 1960). and an abundant population was reported at a salinity of 11.5 ppt during an Flowering: The report will display the kingdom and all descendants leading down to the name you choose. the fine sediment component and a lowering of pH and EH (Zieman 1976). for three species of seagrass in the Indian River Lagoon. Ruppia occurred in slightly than seagrass infauna. usually buried from 2 to 4 inches in the substratum (Phillips 1960) but was also summer. Plant increase and growth of Thalassia A species list of seagrass epiphytes of the reproduction probably accounts for significant spreading of turtle grass beds. Direct grazing on Florida seagrasses is limited to a number of species, e.g., sea turtles, parrotfish, surgeonfish, sea urchins and perhaps pinfish. It contains a toxic substance which deters herbivorous fish from eating it. Biscayne Bay, FL, flowers were seen only during the third week in May, with The rhizome of Thalassia testudinum is locally more abundant than H. wrightii. Data from the first two 6% for Thalassia.
