Harmful Algae, 2020
Some benthic dinoflagellates produce toxins that can affect other organisms including humans, and their proliferation seems to be related to the environmental variability.

Some Chemical Constituents of Turtle Grass, Thalassia testudinum
Bulletin of the Torrey Botanical Club, 1959Primary biological productivity in the coastal waters of Puerto Rico is based upon the synthetic processes of phytoplankton, benthic algae, mangroves, corals and the turtle grass, Thalassia testudinum. A considerable portion of the total production of organic matter in this region appears to be contributed by the large beds of Thalassia, widely ...

Multiple stressors result in reduced reproductive effort by Thalassia testudinum in Florida Bay, USA
Marine Ecology Progress Series, 2020Sexual reproduction remains an understudied aspect of seagrass ecology. We examined spatiotemporal variability in the percentage of short shoots with sexual reproductive structures and the proportion of sites that had flowered as an indicator of ...

Factors affecting the reproductive ecology of Thalassia testudinum (Hydrocharitaceae)
Aquatic Botany, 1987Abstract Morpho-anatomical studies of short-shoots of Thalassia testudinum Banks ex Konig collected in Tampa Bay, Florida from February 1979 to October 1980 ( n = 5394) demonstrated the presence of sexually reproductive short-shoots during all months, except August and September. Mean inflorescence lengths (MIL) indicated that little inflorescence

The grazing of Thalassia testudinum in Kingston Harbour, Jamaica
Aquatic Botany, 1976Abstract 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 ...

Nitrogen fixation (acetylene reduction) in the phyllosphere of Thalassia testudinum
Marine Biology, 1977N2 fixation (C2H2 reduction) associated with the leaves of the sea grass Thalassia testudinum was investigated at 5 sites in South Florida (Biscayne Bay) and one site in the Bahamas (Bimini Harbor). Significant activities were correlated with the occurrence of a heterocystous blue-green alga (Calothrix sp.) on the leaves.

The water economy of the sea grass Thalassia testudinum
Marine Biology, 1971The osmotic values in the leaves of Thalassia testudinumBanks ex Konig, collected from the natural habitat, were found to be 32 atm; the relative transpiration was 100%. Electronmicroscopical analysis of the cuticle reveals many perforations. The critical sublethal water deficit lies near 65%.

Thalassia testudinum productivity: A field comparison of measurement methods
Marine Biology, 1976A 6-day in situ comparison between the Wetzel inorganic 14C uptake and Zieman leaf-biomass techniques for measuring net primary production rates in the seagrass Thalassia testudinum was performed in the northeastern Gulf of Mexico. Measurement differences between the two methods were insignificant when the 14C uptake technique was corrected for ...
