The grazing of Thalassia testudinum in Kingston Harbour, Jamaica

Aquatic Botany, 1976
Abstract There are approximately 1,000 ha of Thalassia testudinum Banks ex Konig in Kingston Harbour, and the most extensive and luxuriant meadows are concentrated in the shallow waters (0.5–4.0 m depth) at the western end of the harbour. A pure stand of Thalassia of mean blade standing crop value (epiphyte-free) of 249 g dry weight/m2 and ...

Wound-induced accumulations of condensed tannins in turtlegrass, Thalassia testudinum

Aquatic Botany, 2008
Abstract Turtlegrass, Thalassia testudinum, produces high concentrations of proanthocyanidins (condensed tannins) which we hypothesized are induced by grazing, as a component of a general wound response. To test this we quantified condensed tannins in a variety of turtlegrass tissues following simulated fish grazing, grazing by the urchin Lytechinus ...

Sulfide effects on Thalassia testudinum carbon balance and adenylate energy charge

Aquatic Botany, 2000
Abstract Low iron content in tropical carbonate sediments limits the formation of iron–sulfide compounds such as pyrite. Thus, seagrasses in the tropics may be more susceptible to sulfide toxicity. Sediment sulfide levels greater than 2 mM and up to 13 mM have been hypothesized to cause widespread ‘die-back’ of the tropical seagrass Thalassia ...

Thalassia testudinum response to the interactive stressors hypersalinity, sulfide and hypoxia

Aquatic Botany, 2007
Abstract A large-scale mesocosm (sixteen 500 L tanks) experiment was conducted to investigate the effects of hypersalinity (45–65 psu), porewater sulfide (2–6 mM) and nighttime water column hypoxia (5–3 mg L−1) on the tropical seagrass Thalassia testudinum Banks ex Konig.

Turtle Grass (Thalassia testudinum Banks ex König) — A Seagrass

1988
Seagrasses are aquatic angiosperms that live and complete their life cycles totally submerged in a saline-to-brackish medium (Thayer et al. 1975). They are unique in that they are the only land plants that have totally returned to the sea. Although not true grasses, their habit of ribbon-like leaves results in meadows or beds resembling terrestrial ...

Photosynthetic activity detected in the seed epidermis of Thalassia testudinum

Aquatic Botany, 2017
Abstract Seagrasses are marine angiosperms that have evolved from terrestrial ancestors. Photosynthetic activity on seed has been studied before in Posidonia genus. T. testudinum and P. oceanica share some evolutionary aspects as they live in more stable environments. As in P. oceanica , T.
