Sea grasses, a new unreported habitat for the heterobranch mollusk Umbraculum umbraculum in the Caribbean region

Marine and Fishery Sciences, 2020
Herein, a new habitat for the heterobranch mollusk Umbraculum is described. One specimen was found on a Thalassia testudinum bed at Taganga Bay at 3 m depth, a buffer area of the Tayrona National Park, Colombian Caribbean.

Composición química de la seiba (Thalassia testudinum K.D. Koenig, 1805)

Revista de Investigaciones Marinas, 2022
La perspectiva de usar las hojas de seiba como suplemento alimentario para el ganado o como abono agrícola requirió determinar la composición química de sus hojas con los siguientes resultados: peso seco 17-34%; cenizas 21-52%; carbono 23-50%; proteínas 8-12%; azúcares reductores 2-13%; fibras 29-40% y grasas 0,5-0,7% con variaciones entre hojas sin ...

Experimental evidence of pollination in marine flowers by invertebrate fauna

Nature Communications, 2016
Marine plants reproduce by hydrophilly, that is, the movement of pollen by water. Here, the authors show that invertebrates can also carry pollen from male to female Thalassia testudinum plants.

Fruit development in the seagrass Thalassia testudinum: Possible relationships between structure, physiology and defense

, 2021
Even though seagrasses are clonal plants, they also invest substantial energy in sexual reproduction. However, little is known about the development of the reproductive structures of seagrasses and their complex interactions with ambient conditions. Here,

Effects of community structure on the seagrass Thalassia testudinum [PDF]

Marine Ecology Progress Series, 1999
The influence of community structure on the seagrass Thalassia testudinum was studied in 3 distinct communities low and high density monocultures, and patches intermixed with Halodule wrightii, in Cockroach Bay, Tampa, Florida. T. testudinum shoot-specific leaf mass and growth were significantly higher in low density monocultures, and both variables ...

Recovery of a cultivation grazer: A mechanism for compensatory growth of Thalassia testudinum in a Caribbean seagrass meadow grazed by green turtles

Journal of Ecology, 2020
Recovery of green turtles (Chelonia mydas), mega‐herbivores that consume seagrasses, is resulting in dramatic ecosystem‐wide changes as meadows are returned to a natural grazed state.

Spatio-Temporal Variation in Cyanobacteria and Epiphytic Algae of Thalassia testudinum in Two Localities of Southern Quintana Roo, Mexico

Diversity
The leaves of Thalassia testudinum provide an ideal substrate for the establishment of small-sized algae with different morphologies that are abundant and diverse. There are few studies on epiphytism in Mexico, and most of them are floristic lists.

Nutrient availability induces community shifts in seagrass meadows grazed by turtles [PDF]

PeerJ, 2019
In the Caribbean, green turtles graze seagrass meadows dominated by Thalassia testudinum through rotational grazing, resulting in the creation of grazed and recovering (abandoned) patches surrounded by ungrazed seagrasses.

Estimación de la Biomasa de THALASSIA TESTUDINUM a partir de datos de Biomasa húmeda.

Revista de Investigaciones Marinas, 2023
La biomasa seca del macrofitobentos se emplea para analizar la abundancia, productividad y otros procesos que se producen en los ecosistemas. Pero el secado de la biomasa implica la destrucción del especimen, así como consumo de tiempo, electricidad. En
