Biological activities of the sulfated polysaccharide from the vascular plant Halodule wrightii [PDF]

Revista Brasileira de Farmacognosia, 2012
A sulfated polysaccharide (SPSG) was successfully isolated from seagrass Halodule wrightii Asch., Cymodoceaceae, and its antioxidant and anticoagulant activities were investigated. The data presented here showed that the SPSG is a 11 kDa sulfated heterogalactan with a sulfatation degree of 20.63% and it also contains glucose and xylose.

New records of Erichsonella attenuata (Isopoda: Valvifera: Idoteidae)in the Gulf of Mexico

Revista Mexicana de Biodiversidad, 2016
Erichsonella attenuata is an isopod species distributed in the Western Atlantic region of the Gulf of Mexico and is associated with sea-grass beds composed of Ruppia maritima, Halodule wrightii and Thalassia testudinum. In the Gulf of Mexico, this isopod

Seagrasses benefit from mild anthropogenic nutrient additions

Frontiers in Marine Science, 2022
Seagrasses are declining globally, in large part due to increased anthropogenic coastal nutrient loads that enhance smothering by macroalgae, attenuate light, and are toxic when in excessive concentrations of inorganic nitrogen and phosphorus.

Patterns of Species Dominance in Two Coastal Restorations: Evidence of Sustained Seagrass Success over Long Time Scales

Diversity
Restoration in coastal settings by reconstructing seagrass coverage after widespread loss has generally been monitored over a short time, with few studies extending ≥5 years.

Decomposition of senescent blades of the seagrass Halodule wrightii in a subtropical lagoon

Marine Ecology Progress Series, 1993
Senescent blades from the seagrass Halodule wrightii Aschers were suspended in the water column of Laguna Madre (Texas, USA) for a period of 419 d , representing the longest seagrass decomposition study to date. The initial stage of decomposition was characterized by a rapid loss of organic matter (36 % in 24 d ) attributed to leaching. A total of 76 %

Live and Live-Dead Intraspecific Morphometric Comparisons as Proxies for Seagrass Stability in Conservation Paleobiology

Frontiers in Ecology and Evolution, 2022
Comparisons of life and death assemblages are commonly conducted to detect environmental change, including when historical records of live occurrences are unavailable.

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.

American manatees adjust their diet composition and trophic niche breadth across different coastal regions

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Marine mammals can exhibit high plasticity in foraging strategies, but how such plasticity is driven by environmental conditions is poorly understood. The American manatee (Trichechus manatus), a large, endangered herbivore, inhabits marine, estuarine, and freshwater environments.

Quantification and classification of the main environmental impacts on a Halodule wrightii seagrass meadow on a tropical island in northeastern Brazil

Anais da Academia Brasileira de Ciências, 2012
Multiple stress mechanisms have caused a worldwide decrease in seagrasses, which are vulnerable to environmental and/or anthropogenic pressure.
