The mobile macroepifauna associated to Thalassia testudinum meadow was studied in quadrants of 1m2 placed on two fringes (shallow water and deep water) of it in Triganá Bay, Gulf of Urabá, Colombia. The results showed significant differences in coverage,

Stable isotopes reveal complex changes in trophic relationships following nutrient addition in a coastal marine ecosystem [PDF]
Complex links between the top-down and bottomup forces that structure communities can be disrupted by anthropogenic alterations of natural habitats.We used relative abundance and stable isotopes to examine changes in epifaunal food webs in seagrass ...

Short-term impacts of salinity pulses on ionic ratios of the seagrasses Thalassia testudinum and Halodule wrightii [PDF]
We examined the effects of short-term salinity pulses on ion accumulation in the seagrasses Thalassia testudinum and Halodule wrightii. Plant fragments were exposed for approximately 1 week to 10, 23 (ambient salinity), 30, 40, 50 and 70 psu.

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

Interaction between hydrodynamics and seagrass canopy structure: Spatially explicit effects on ammonium uptake rates [PDF]
The hypotheses that (1) different seagrass morphologies may facilitate different nutrient uptake rates under similar hydrodynamic forcing and (2) this effect on nutrient uptake rates is spatially explicit, with the highest uptake rates at edges of ...

Nitrogen uptake and internal recycling in Zostera marina exposed to oyster farming: eelgrass potential as a natural biofilter [PDF]
Oyster farming in estuaries and coastal lagoons frequently overlaps with the distribution of seagrass meadows, yet there are few studies on how this aquaculture practice affects seagrass physiology.

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

CO2 and nutrient-driven changes across multiple levels of organization in zostera noltii ecosystems [PDF]
Increasing evidence emphasizes that the effects of human impacts on ecosystems must be investigated using designs that incorporate the responses across levels of biological organization as well as the effects of multiple stressors.
