Influence of pelagic sargassum influxes on the δ15N in Thalassia testudinum of the Mexican Caribbean coastal ecosystem.

Marine Pollution Bulletin, 2023
The conservation of Mexican Caribbean Ecosystems (MCE) involves ensuring their capacity to provide resources and ecosystem services to society. Monitoring programs are necessary to establish their management and ensure their sustainability.

Scientific analysis of Thalassia testudinum leaves

2022
Seagrass meadows are an important element of coastal ecosystems and they perform numerous environmental functions. Because of their importance, the ability to properly monitor the health of the seagrass meadows is imperative. Seagrass can greatly affect acoustic propagation and therefore acoustics can be used for remotely sensing the health of the ...

Landscape-scale variation in a sulfur-based sediment stress indicator for the seagrass Thalassia testudinum in Florida Bay, USA

Marine Ecology Progress Series, 2021
Intrusion of sediment-derived hydrogen sulfide into above-ground tissues of seagrasses is correlated with reduced growth and has been linked to large-scale die-offs of Thalassia testudinum in Florida Bay, USA. In May of 2019, leaves from T.

The takeover of Thalassia testudinum by Anadyomene sp. at Biscayne Bay, USA, cannot be simply explained by competition for nitrogen and phosphorous.

Marine Pollution Bulletin, 2021
Apart from direct light effects, we tested whether the takeover of the seagrass Thalassia testudinum by the seaweed Anadyomene sp. in high nutrient areas of Biscayne Bay, Florida, USA, is related to a faster nutrient surge uptake capacity of the seaweed ...

Leaf epifauna of the seagrass Thalassia testudinum

Marine Biology, 1982
The abundance, composition and trophic relationships of metazoan leaf epifauna of the marine angiosperm Thalassia testudinum Konig were studied in Barbados, West Indies. Approximately 90 species from 11 phyla consisted chiefly of nematodes, harpacticoid copepods, crustacean nauplii, ostracods, and turbellarians. Epiflora- and detritus-feeders dominated

Photoperiodism and Related Ecology in Thalassia testudinum

Botanical Gazette, 1968
A study was conducted to determine, through ecological observations and experimental manipulation, whether the marine angiosperm Thalassia testudinum Koening and Sims is responsive to photoperiod. The field observations, made in St. Andrew Bay on the northwestern Gulf Coast of Florida and in Biscayne Bay on the southern Atlantic Coast of Florida ...

Dormancy and foliar density regulation in Thalassia testudinum

Aquatic Botany, 2000
Abstract The hypothesis that the tropical seagrass, Thalassia testudinum from the Puerto Morelos reef lagoon (Mexican Caribbean) has a dormant apical meristem bank (as opposed to a dormant axillary meristem bank) was investigated by morphological and anatomical analyses of vertical shoot apices.

Some Chemical Constituents of Turtle Grass, Thalassia testudinum

Bulletin of the Torrey Botanical Club, 1959
Primary 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 ...

Effects of heavy rainfall on Thalassia testudinum beds

Aquatic Botany, 2007
In 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.
