Changes in trace metals in Thalassia testudinum after hurricane impacts

Marine Pollution Bulletin, 2011
Major hurricanes Emily and Wilma hit the Mexican Caribbean in 2005. Changes in trace metals in the seagrass Thalassia testudinum prior to (May 2004, 2005) and following passage of these hurricanes (May, June 2006) were determined at four locations along a ≈ 130 km long stretch of coast.

Vegetative Branching in Thalassia testudinum (Hydrocharitaceae)-A Correction

Botanical Gazette, 1972
Horizontal scale-bearing rhizomes in Thalassia produce, at fairly regular but distant intervals, lateral branches which develop into erect, leafy shoots. These branches are leaf-opposed, not axillary. Since they originate precociously and are at first equal to the main axis, it had been suggested that they are the result of an equal dichotomy of the ...

Thalassia testudinum as a potential vector for incorporating microplastics into benthic marine food webs.

Marine Pollution Bulletin, 2018
Seagrasses are among the most productive shallow water ecosystems, serving a diverse assemblage of fish and invertebrates. Tropical seagrass communities are dominated by the turtle grass Thalassia testudinum, whose wide, flattened blades host diverse ...

ABCG2/BCRP interaction with the sea grass Thalassia testudinum

Drug Metabolism and Personalized Therapy, 2015
Abstract Background: The aqueous ethanolic extract from leaves of the marine plant Thalassia testudinum has shown antioxidant, cytoprotective, and neuroprotective properties. The chemical composition of this extract, rich in polyphenols, could interfere with active transport of drugs out of the cell and circumvent the ...

Ecological risks of trace elements in sediments and Thalassia testudinum from Cartagena Bay.

Marine Pollution Bulletin
This study assesses the ecological risks from trace elements in sediments and Thalassia testudinum in two contrasting areas of the Colombian Caribbean: Cartagena Bay (CTG Bay), an industrialized zone, and the Rosario and San Bernardo Corals National ...

Factors affecting the reproductive ecology of Thalassia testudinum (Hydrocharitaceae)

Aquatic Botany, 1987
Abstract 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

Hypersalinity affects leaf and meristem O2 dynamics exposing meristems to H2S in the dominant tropical seagrass Thalassia testudinum

, 2020
Large-scale (>80 km2) seagrass mortality events have been reported worldwide. While the mechanisms triggering these sudden die-off events are not well understood, plant hypoxia and H2S intrusion, at times linked to hypersaline conditions, have been ...

Vertical growth of Thalassia testudinum: seasonal and interannual variability

Aquatic Botany, 1994
The vertical growth of shoots of the seagrass Thalassia testudinum Banks ex Konig in four meadows, along a range of exposure to waves, in the Mexican Caribbean was examined to elucidate its magnitude and its relationship to sediment dynamics. Average internodal length varied between 0.17 and 12.75 mm, and was greatest in the meadow which experienced ...

Structural variation of potentially toxic epiphytic dinoflagellates on Thalassia testudinum from two coastal systems of Colombian Caribbean.

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.

Multiple stressors result in reduced reproductive effort by Thalassia testudinum in Florida Bay, USA

Marine Ecology Progress Series, 2020
Sexual 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 ...
