Regrowth of the seagrass Thalassia testudinum into propeller scars
Aquatic Botany, 1997Abstract Regrowth of turtle grass, Thalassia testudinum Banks ex Konig, into existing propeller scars and artificial cuts was studied in a mangal estuary located in Tampa Bay, Florida. Sediments from scars and cuts and adjacent grass beds were not significantly different in relation to particle size distribution and levels of calcium carbonate ...

Seagrasses are among the most productive shallow water ecosystems, serving a diverse assemblage of fish and invertebrates. Tropical seagrass communities are dominated by the turtle grass Thalassia testudinum, whose wide, flattened blades host diverse ...

Vegetative Branching in Thalassia testudinum (Hydrocharitaceae)-A Correction
Botanical Gazette, 1972Horizontal scale-bearing rhizomes in Thalassia produce, at fairly regular but distant intervals, lateral branches which develop into erect, leafy shoots. These branches are leaf-opposed, not axillary. Since they originate precociously and are at first equal to the main axis, it had been suggested that they are the result of an equal dichotomy of the ...

Effects of heavy rainfall on Thalassia testudinum beds
Aquatic Botany, 2007In December 1999 heavy continuous rains that lasted one week affected the Venezuelan coastline. At Morrocoy National Park, a large marine reserve, rainfall values surpassed previous 32-year records and led to a decrease of salinity to 3 psu, which lasted for over a month at some locations.

Occurrence of intracellular crystals in leaves of Thalassia testudinum
Aquatic Botany, 2004Abstract Refractive, rhomboidal, intracellular crystals were identified in leaves of Thalassia testudinum Banks ex Konig (turtlegrass) from the Bahamas (Lee Stocking Island); Florida (Key Largo and Key West); and Texas (Laguna Madre). At all four collection sites, crystals were present in leaves of all ages and in most but not all epidermal cells ...

Observations on the reproductive ecology of Thalassia testudinum (hydrocharitaceae)
Aquatic Botany, 1981Abstract A phenological inversion in Thalassia testudinum Banks ex Konig was indicated by the presence of early fruit stage in midwinter. Further observations in Januarary 1979 detected early reproductive bud presence, and 44% of the short-shoots examined were reproductive.

Ecological risks of trace elements in sediments and Thalassia testudinum from Cartagena Bay.
Marine Pollution BulletinThis study assesses the ecological risks from trace elements in sediments and Thalassia testudinum in two contrasting areas of the Colombian Caribbean: Cartagena Bay (CTG Bay), an industrialized zone, and the Rosario and San Bernardo Corals National ...

Spectral reflectance of Thalassia testudinum with varying depths
IEEE International Geoscience and Remote Sensing Symposium, 2003Seagrasses are an important component in the marine ecosystem, and also a vulnerable resource subject to environmental change. Satellite and airborne remote sensing has been applied in monitoring and mapping seagrasses. One research issue from a remote sensing perspective is the spectral impact of water column depths since seagrasses normally grow in ...

N2 fixation in the rhizosphere of Thalassia testudinum
Canadian Journal of Microbiology, 1980N2 fixation (C2H2 reduction) associated with the roots, rhizomes, and sediments (rhizosphere cores) of the seagrass Thalassia testudinum was measured at sites in South Florida (Soldier Key, Biscayne Bay) and the Bahamas (Bimini Harbor). Rates of C2H2 reduction were higher in anaerobic than in aerobic assays and were linear for several hours after an ...

Large-scale (>80 km2) seagrass mortality events have been reported worldwide. While the mechanisms triggering these sudden die-off events are not well understood, plant hypoxia and H2S intrusion, at times linked to hypersaline conditions, have been ...
